-** Emacs comes with a new set of icons.
-These icons are displayed on the taskbar and/or titlebar when Emacs
-runs in a graphical environment. Source files for these icons can be
-found in etc/images/icons. (You can't change the icons displayed by
-Emacs by changing these files directly. On X, the icon is compiled
-into the Emacs executable; see gnu.h in the source tree. On MS
-Windows, see nt/icons/emacs.ico.)
+\f
+* Installation Changes in Emacs 22.2
----
-** Emacs now supports new configure options `--program-prefix',
-`--program-suffix' and `--program-transform-name' that affect the names of
-installed programs.
+** Emacs is now licensed under the GNU GPL version 3 (or later).
----
-** Emacs can now be built without sound support.
+** Support for GNU/kFreeBSD (GNU userland and FreeBSD kernel) was added.
----
-** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk'
-when you run configure. This requires Gtk+ 2.4 or newer. This port
-provides a way to display multilingual text in menus (with some caveats).
+** Deprecated machine types and operating systems
----
-** The `emacsserver' program has been removed, replaced with Lisp code.
+Certain machine types and operating systems have been deprecated. On
+these systems, configure will print a warning and exit, and you must
+edit the configure script for compilation to proceed. The deprecated
+systems will not be supported at all in Emacs 23. We are not aware of
+anyone running Emacs on these systems; if you are, please email
+emacs-devel@gnu.org to take it off the list of deprecated systems.
----
-** The `yow' program has been removed.
-Use the corresponding Emacs feature instead.
+*** Deprecated machine types
+pmax, hp9000s300, ibm370aix, ncr386, ews4800, mips-siemens, powerpcle,
+and tandem-s2
----
-** By default, Emacs now uses a setgid helper program to update game
-scores. The directory ${localstatedir}/games/emacs is the normal
-place for game scores to be stored. You can control this with the
-configure option `--with-game-dir'. The specific user that Emacs uses
-to own the game scores is controlled by `--with-game-user'. If access
-to a game user is not available, then scores will be stored separately
-in each user's home directory.
+*** Deprecated operating systems
+bsd386, bsdos2-1, bsdos2, bsdos3, bsdos4, bsd4-1, bsd4-2, bsd4-3,
+usg5-0, usg5-2-2, usg5-2, usg5-3, ultrix4-3, 386bsd, hpux, hpux8,
+hpux9, hpux9shr, hpux10, hpux10-20, aix3-1, aix3-2-5, aix3-2, aix4-1,
+nextstep, ux4800, uxpds, and uxpv
----
-** Leim is now part of the Emacs distribution.
-You no longer need to download a separate tarball in order to build
-Emacs with Leim.
+* Changes in Emacs 22.2
+
+** `describe-project' is renamed to `describe-gnu-project'.
+
+** `view-todo' is renamed to `view-emacs-todo'.
+
+** `find-name-dired' now uses -iname rather than -name
+for case-insensitive filesystems. The default behavior is determined
+by the value of `read-file-name-completion-ignore-case'; if you don't
+like that, customize the value of the new option `find-name-arg'.
+
+** In Image mode, whenever the displayed image is wider and/or higher
+than the window, the usual keys for moving the cursor cause the image
+to be scrolled horizontally or vertically instead.
+
+** Emacs can use stock icons in the tool bar when compiled with Gtk+.
+However, this feature is disabled by default. To enable it, put
+
+ (setq icon-map-list '(x-gtk-stock-map))
+
+in your .emacs or some other startup file. For more information, see
+the documentation for the two variables icon-map-list and x-gtk-stock-map.
+
+** Scrollbars follow the system theme on Windows XP and later.
+Windows XP introduced themed scrollbars, but applications have to take
+special steps to use them. Emacs now has the appropriate resources linked
+in to make it use the scrollbars from the system theme.
+
+** focus-follows-mouse defaults to nil on MS Windows.
+Previously this variable was incorrectly documented as having no effect
+on MS Windows, and the default was inappropriate for the majority of
+Windows installations. Users of software which modifies the behaviour of
+Windows to cause focus to follow the mouse will now need to explicitly set
+this variable.
+
+** `bad-packages-alist' will warn about external packages that are known
+to cause problems in this version of Emacs.
+
+** The values of `dired-recursive-deletes' and `dired-recursive-copies'
+have been changed to `top'. This means that the user is asked once,
+before deleting/copying the indicated directory recursively.
+
+** `browse-url-emacs' loads a URL into an Emacs buffer. Handy for *.el URLs.
+
+** The command gdba has been removed as gdb works now for those cases where it
+was needed. In text command mode, if you have problems before execution has
+started, use M-x gud-gdb.
+
+** desktop.el now detects conflicting uses of the desktop file.
+When loading the desktop, desktop.el can now detect that the file is already
+in use. The default behavior is to ask the user what to do, but you can
+customize it with the new option `desktop-load-locked-desktop'. When saving,
+desktop.el warns about attempts to overwrite a desktop file if it determines
+that the desktop being saved is not an update of the one on disk.
+
+** Compilation mode now correctly respects the value of
+`compilation-scroll-output' between invocations. Previously, output
+was mistakenly scrolled on compiles after the first. Customize
+`compilation-scroll-output' if you want to retain the scrolling.
+
+** `font-lock-comment-face' no longer differs from the default on
+displays with fewer than 16 colors and dark background (e.g. older
+xterms and the Linux console). On such displays, only the comment
+delimiters will appear to be fontified (in the new face
+`font-lock-comment-delimiter-face'). To restore the old appearance,
+customize `font-lock-comment-face'. Another alternative is to use a
+newer terminal emulator that supports more colors (256 is now common).
+For example, for xterm compatible emulators that support 256 colors,
+you can run emacs like this:
+env TERM=xterm-256color emacs -nw
+(This was new in Emacs 22.1, but was not described. In Emacs 22.1
+this also happened for terminals with a light background, that is not
+the case anymore).
+
+* New Modes and Packages in Emacs 22.2
+
+** bibtex-style-mode helps you write BibTeX's *.bst files.
+
+** The new package css-mode.el provides a major mode for editing CSS files.
+
+** The new package vera-mode.el provides a major mode for editing Vera files.
+
+** The new package verilog-mode.el provides a major mode for editing Verilog files.
+
+** The new package socks.el implements the SOCKS v5 protocol.
+
+** VC
+
+*** VC backends can provide completion of revision names.
+
+*** VC backends can provide extra menu entries to the "Version Control" menu.
+This can be used to add menu entries for backend specific functions.
+
+*** VC has some support for Mercurial (Hg).
+
+*** VC has some support for Monotone (Mtn).
+
+*** VC has some support for Bazaar (Bzr).
+
+*** VC has some support for Git.
+
+* Incompatible Lisp Changes in Emacs 22.2
+
+** shell.el no longer defines the aliases `dirtrack-toggle' and
+`dirtrack-mode' for `shell-dirtrack-mode'. These names were removed
+because they clash with commands provided by dirtrack.el. Use
+`shell-dirtrack-mode' instead.
+
+* Lisp Changes in Emacs 22.2.
+
+** Frame-local variables are deprecated and are slated for removal.
+They can easily be emulated. Rather than calling `make-variable-frame-local'
+and accessing the variable value directly, explicitly check for a
+frame-parameter, and if there is one, use its value in preference to
+that of the variable. Note that buffer-local values should take
+precedence over frame-local ones, so you may wish to check `local-variable-p'
+first.
+
+** The function invisible-p returns non-nil if the character
+after a specified position is invisible.
+
+** inhibit-modification-hooks is bound to t while running modification hooks.
+As a happy consequence, after-change-functions and before-change-functions
+are not bound to nil any more while running an (after|before)-change-function.
+
+** New function `window-full-width-p' returns t if a window is as wide
+as its frame.
+
+** The new function `image-refresh' refreshes all images associated
+with a given image specification.
+
+** The new function `combine-and-quote-strings' concatenates a list of strings
+using a specified separator. If a string contains double quotes, they
+are escaped in the output.
+
+** The new function `split-string-and-unquote' performs the inverse operation to
+`combine-and-quote-strings', i.e. splits a single string into a list
+of strings, undoing any quoting added by `combine-and-quote-strings'.
+(For some separator/string combinations, the original strings cannot
+be recovered.)
+
+\f
+* Installation Changes in Emacs 22.1
+
+** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk'
+when you run configure. This requires Gtk+ 2.4 or newer. This port
+provides a way to display multilingual text in menus (with some caveats).

** The Emacs Lisp Reference Manual is now part of the distribution.
The Emacs Lisp Reference Manual in Info format is built as part of the
Emacs build procedure and installed together with the Emacs User
-Manual. A menu item was added to the menu bar that makes it easy

** Emacs now includes support for loading image libraries on demand.
(Currently this feature is only used on MS Windows.) You can configure
the supported image types and their associated dynamic libraries by
setting the variable `image-library-alist'.
----
-** Support for a Cygwin build of Emacs was added.
+** Emacs can now be built without sound support.
----
-** Support for FreeBSD/Alpha has been added.
+** Emacs Lisp source files are compressed by default if `gzip' is available.
----
-** Support for GNU/Linux systems on S390 machines was added.

** Building with -DENABLE_CHECKING does not automatically build with union
types any more. Add -DUSE_LISP_UNION_TYPE if you want union types.

\f
* Startup Changes in Emacs 22.1
-+++
-** New command line option -Q or --quick.
-This is like using -q --no-site-file, but in addition it also disables
-the fancy startup screen.
+** Init file changes
+If the init file ~/.emacs does not exist, Emacs will try
+~/.emacs.d/init.el or ~/.emacs.d/init.elc. Likewise, if the shell init file
+~/.emacs_SHELL is not found, Emacs will try ~/.emacs.d/init_SHELL.sh.
-+++
-** New command line option -D or --basic-display.
-Disables the menu-bar, the tool-bar, the scroll-bars, tool tips, and
-the blinking cursor.
+** Emacs can now be invoked in full-screen mode on a windowed display.
+When Emacs is invoked on a window system, the new command-line options
+`--fullwidth', `--fullheight', and `--fullscreen' produce a frame
+whose width, height, or both width and height take up the entire
+screen size. (For now, this does not work with some window managers.)
+
+** Emacs now displays a splash screen by default even if command-line
+arguments were given. The new command-line option --no-splash
+disables the splash screen; see also the variable
+`inhibit-splash-screen' (which is also aliased as
+`inhibit-startup-message').
+
+** New user option `inhibit-startup-buffer-menu'.
+When loading many files, for instance with `emacs *', Emacs normally
+displays a buffer menu. This option turns the buffer menu off.
-+++
** New command line option -nbc or --no-blinking-cursor disables
the blinking cursor on graphical terminals.
-+++
** The option --script FILE runs Emacs in batch mode and loads FILE.
It is useful for writing Emacs Lisp shell script files, because they
can start with this line:
#!/usr/bin/emacs --script
-+++
+** The -f option, used from the command line to call a function,
+now reads arguments for the function interactively if it is
+an interactively callable function.
+
** The option --directory DIR now modifies `load-path' immediately.
Directories are added to the front of `load-path' in the order they
appear on the command line. For example, with this command line:
Emacs looks for library `foo' in the parent directory, then in /tmp, then
in the other directories in `load-path'. (-L is short for --directory.)
-+++
-** The command line option --no-windows has been changed to
---no-window-system. The old one still works, but is deprecated.
-
----
-** If the environment variable DISPLAY specifies an unreachable X display,
-Emacs will now startup as if invoked with the --no-window-system option.
-
-+++
-** The -f option, used from the command line to call a function,
-now reads arguments for the function interactively if it is
-an interactively callable function.
-
-+++
** When you specify a frame size with --geometry, the size applies to
all frames you create. A position specified with --geometry only
affects the initial frame.
----
** Emacs built for MS-Windows now behaves like Emacs on X does,
-wrt its frame position: if you don't specify a position (in your
-.emacs init file, in the Registry, or with the --geometry command-line
-option), Emacs leaves the frame position to the Windows' window
-manager.
-
-+++
-** Emacs can now be invoked in full-screen mode on a windowed display.
-When Emacs is invoked on a window system, the new command-line options
-`--fullwidth', `--fullheight', and `--fullscreen' produce a frame
-whose width, height, or both width and height take up the entire
-screen size. (For now, this does not work with some window managers.)
-
-+++
-** Emacs now displays a splash screen by default even if command-line
-arguments were given. The new command-line option --no-splash
-disables the splash screen; see also the variable
-`inhibit-startup-message' (which is also aliased as
-`inhibit-splash-screen').
-
-+++
-** The default is now to use a bitmap as the icon, so the command-line options
---icon-type, -i has been replaced with options --no-bitmap-icon, -nbi to turn
-the bitmap icon off.
+with respect to its frame position: if you don't specify a position
+(in your .emacs init file, in the Registry, or with the --geometry
+command-line option), Emacs leaves the frame position to the Windows'
+window manager.
-+++
-** New user option `inhibit-startup-buffer-menu'.
-When loading many files, for instance with `emacs *', Emacs normally
-displays a buffer menu. This option turns the buffer menu off.
+** The command line option --no-windows has been changed to
+--no-window-system. The old one still works, but is deprecated.
-+++
-** Init file changes
-If the init file ~/.emacs does not exist, Emacs will try
-~/.emacs.d/init.el or ~/.emacs.d/init.elc. Likewise, if the shell init file
-~/.emacs_SHELL is not found, Emacs will try ~/.emacs.d/init_SHELL.sh.
+** If the environment variable DISPLAY specifies an unreachable X display,
+Emacs will now startup as if invoked with the --no-window-system option.
-+++
** Emacs now reads the standard abbrevs file ~/.abbrev_defs
automatically at startup, if it exists. When Emacs offers to save
modified buffers, it saves the abbrevs too if they have changed. It
can do this either silently or asking for confirmation first,
according to the value of `save-abbrevs'.
-+++
+** New command line option -Q or --quick.
+This is like using -q --no-site-file, but in addition it also disables
+the fancy startup screen.
+
+** New command line option -D or --basic-display.
+Disables the menu-bar, the tool-bar, the scroll-bars, tool tips, and
+the blinking cursor.
+
+** The default is now to use a bitmap as the icon.
+The command-line options --icon-type, -i have been replaced with
+options --no-bitmap-icon, -nbi to turn the bitmap icon off.
+
** If the environment variable EMAIL is defined, Emacs now uses its value
to compute the default value of `user-mail-address', in preference to
concatenation of `user-login-name' with the name of your host machine.
\f
* Incompatible Editing Changes in Emacs 22.1
-+++
-** M-g is now a prefix key.
-M-g g and M-g M-g run goto-line.
-M-g n and M-g M-n run next-error (like C-x `).
-M-g p and M-g M-p run previous-error.
-
-+++
-** C-u M-g M-g switches to the most recent previous buffer,
-and goes to the specified line in that buffer.
-
-When goto-line starts to execute, if there's a number in the buffer at
-point then it acts as the default argument for the minibuffer.
-
-+++
-** The old bindings C-M-delete and C-M-backspace have been deleted,
-since there are situations where one or the other will shut down
-the operating system or your X server.
+** You can now follow links by clicking Mouse-1 on the link.
-+++
-** line-move-ignore-invisible now defaults to t.
+See below for more details.
-+++
** When the undo information of the current command gets really large
(beyond the value of `undo-outer-limit'), Emacs discards it and warns
you about it.
-+++
-** `apply-macro-to-region-lines' now operates on all lines that begin
-in the region, rather than on all complete lines in the region.
+** When Emacs prompts for file names, SPC no longer completes the file name.
+This is so filenames with embedded spaces could be input without the
+need to quote the space with a C-q. The underlying changes in the
+keymaps that are active in the minibuffer are described below under
+"New keymaps for typing file names".
-+++
-** A prefix argument is no longer required to repeat a jump to a
-previous mark if you set `set-mark-command-repeat-pop' to t. I.e. C-u
-C-SPC C-SPC C-SPC ... cycles through the mark ring. Use C-u C-u C-SPC
-to set the mark immediately after a jump.
+If you want the old behavior back, add these two key bindings to your
+~/.emacs init file:
-+++
-** The info-search bindings on C-h C-f, C-h C-k and C-h C-i
-have been moved to C-h F, C-h K and C-h S.
+ (define-key minibuffer-local-filename-completion-map
+ " " 'minibuffer-complete-word)
+ (define-key minibuffer-local-must-match-filename-map
+ " " 'minibuffer-complete-word)
+
+** The completion commands TAB, SPC and ? in the minibuffer apply only
+to the text before point. If there is text in the buffer after point,
+it remains unchanged.
-+++
** In incremental search, C-w is changed. M-%, C-M-w and C-M-y are special.
See below under "incremental search changes".
----

-directory with Dired.
-
-You can get the old behavior by typing C-x C-f M-n RET, which fetches
-the actual file name into the minibuffer.
+** M-g is now a prefix key.
+M-g g and M-g M-g run goto-line.
+M-g n and M-g M-n run next-error (like C-x `).
+M-g p and M-g M-p run previous-error.

-to the text before point. If there is text in the buffer after point,
-it remains unchanged.
+** C-u M-g M-g switches to the most recent previous buffer,
+and goes to the specified line in that buffer.
-+++
-** When Emacs prompts for file names, SPC no longer completes the file name.
-This is so filenames with embedded spaces could be input without the
-need to quote the space with a C-q. The underlying changes in the
-keymaps that are active in the minibuffer are described below under
-"New keymaps for typing file names".
+When goto-line starts to execute, if there's a number in the buffer at
+point then it acts as the default argument for the minibuffer.

** M-o now is the prefix key for setting text properties;
M-o M-o requests refontification.

-+++
** In Dired's ! command (dired-do-shell-command), `*' and `?' now
control substitution of the file names only when they are surrounded
by whitespace. This means you can now use them as shell wildcards
doublequotes make no difference in the shell, but they prevent
special treatment in `dired-do-shell-command'.
+** The info-search bindings on C-h C-f, C-h C-k and C-h C-i
+have been moved to C-h F, C-h K and C-h S.
+
+** `apply-macro-to-region-lines' now operates on all lines that begin
+in the region, rather than on all complete lines in the region.
+
+** line-move-ignore-invisible now defaults to t.
+
** Adaptive filling misfeature removed.
It no longer treats `NNN.' or `(NNN)' as a prefix.
----
+** The old bindings C-M-delete and C-M-backspace have been deleted,
+since there are situations where one or the other will shut down
+the operating system or your X server.
+
** The register compatibility key bindings (deprecated since Emacs 19)
have been removed:
C-x / point-to-register (Use: C-x r SPC)

* Editing Changes in Emacs 22.1
-+++
+** The max size of buffers and integers has been doubled.
+On 32bit machines, it is now 256M (i.e. 268435455).
+
** !MEM FULL! at the start of the mode line indicates that Emacs
cannot get any more memory for Lisp data. This often means it could
crash soon if you do things that use more memory. On most systems,
not make !MEM FULL! disappear, you should save your work and start
a new Emacs.
-+++
-** The max size of buffers and integers has been doubled.
-On 32bit machines, it is now 256M (i.e. 268435455).
+** `undo-only' does an undo which does not redo any previous undo.
-+++
-** You can now switch buffers in a cyclic order with C-x C-left
-(previous-buffer) and C-x C-right (next-buffer). C-x left and
-C-x right can be used as well. The functions keep a different buffer
-cycle for each frame, using the frame-local buffer list.
+** Yanking text now discards certain text properties that can
+be inconvenient when you did not expect them. The variable
+`yank-excluded-properties' specifies which ones. Insertion
+of register contents and rectangles also discards these properties.
-+++
-** `undo-only' does an undo which does not redo any previous undo.
+** New command `kill-whole-line' kills an entire line at once.
+By default, it is bound to C-S-<backspace>.
-+++
** M-SPC (just-one-space) when given a numeric argument N
converts whitespace around point to N spaces.
----
+** You can now switch buffers in a cyclic order with C-x C-left
+(previous-buffer) and C-x C-right (next-buffer). C-x left and
+C-x right can be used as well. The functions keep a different buffer
+cycle for each frame, using the frame-local buffer list.
+
** C-x 5 C-o displays a specified buffer in another frame
but does not switch to that frame. It's the multi-frame
analogue of C-x 4 C-o.
----
+** `special-display-buffer-names' and `special-display-regexps' now
+understand two new boolean pseudo-frame-parameters `same-frame' and
+`same-window'.
+
** New commands to operate on pairs of open and close characters:
`insert-pair', `delete-pair', `raise-sexp'.
-+++
-** New command `kill-whole-line' kills an entire line at once.
-By default, it is bound to C-S-<backspace>.
-
-+++

-be inconvenient when you did not expect them. The variable
-`yank-excluded-properties' specifies which ones. Insertion
-of register contents and rectangles also discards these properties.
-
-+++
-** The default values of paragraph-start and indent-line-function have
-been changed to reflect those used in Text mode rather than those used
-in Indented-Text mode.
-
-+++
** M-x setenv now expands environment variable references.
Substrings of the form `$foo' and `${foo}' in the specified new value
now refer to the value of environment variable foo. To include a `$'
in the value, use `$$'.
-+++
-** `special-display-buffer-names' and `special-display-regexps' now
-understand two new boolean pseudo-frame-parameters `same-frame' and
-`same-window'.
+** The default values of paragraph-start and indent-line-function have
+been changed to reflect those used in Text mode rather than those used
+in Paragraph-Indent Text mode.
-+++
** The default for the paper size (variable ps-paper-type) is taken
from the locale.
-** Mark command changes:
-
-+++
-*** A prefix argument is no longer required to repeat a jump to a
-previous mark, i.e. C-u C-SPC C-SPC C-SPC ... cycles through the
-mark ring. Use C-u C-u C-SPC to set the mark immediately after a jump.
-
-+++
-*** Marking commands extend the region when invoked multiple times.
-
-If you type C-M-SPC (mark-sexp), M-@ (mark-word), M-h
-(mark-paragraph), or C-M-h (mark-defun) repeatedly, the marked region
-extends each time, so you can mark the next two sexps with M-C-SPC
-M-C-SPC, for example. This feature also works for
-mark-end-of-sentence, if you bind that to a key. It also extends the
-region when the mark is active in Transient Mark mode, regardless of
-the last command. To start a new region with one of marking commands
-in Transient Mark mode, you can deactivate the active region with C-g,
-or set the new mark with C-SPC.
-
-+++
-*** M-h (mark-paragraph) now accepts a prefix arg.
-
-With positive arg, M-h marks the current and the following paragraphs;
-if the arg is negative, it marks the current and the preceding
-paragraphs.
-
-+++
-*** Some commands do something special in Transient Mark mode when the
-mark is active--for instance, they limit their operation to the
-region. Even if you don't normally use Transient Mark mode, you might
-want to get this behavior from a particular command. There are two
-ways you can enable Transient Mark mode and activate the mark, for one
-command only.
-
-One method is to type C-SPC C-SPC; this enables Transient Mark mode
-and sets the mark at point. The other method is to type C-u C-x C-x.
-This enables Transient Mark mode temporarily but does not alter the
-mark or the region.
-
-After these commands, Transient Mark mode remains enabled until you
-deactivate the mark. That typically happens when you type a command
-that alters the buffer, but you can also deactivate the mark by typing
-C-g.
-
-+++
-*** Movement commands `beginning-of-buffer', `end-of-buffer',
-`beginning-of-defun', `end-of-defun' do not set the mark if the mark
-is already active in Transient Mark mode.
-
** Help command changes:
-+++
*** Changes in C-h bindings:
C-h e displays the *Messages* buffer.
- C-h w and C-h f new-kill-line reports:
new-kill-line is on C-k
----
+*** The apropos commands now accept a list of words to match.
+When more than one word is specified, at least two of those words must
+be present for an item to match. Regular expression matching is still
+available.
+
+*** The new option `apropos-sort-by-scores' causes the matching items
+to be sorted according to their score. The score for an item is a
+number calculated to indicate how well the item matches the words or
+regular expression that you entered to the apropos command. The best
+match is listed first, and the calculated score is shown for each
+matching item.
+
*** Help commands `describe-function' and `describe-key' now show function
arguments in lowercase italics on displays that support it. To change the
default, customize face `help-argument-name' or redefine the function
`help-default-arg-highlight'.
-+++
*** C-h v and C-h f commands now include a hyperlink to the C source for
variables and functions defined in C (if the C source is available).
-+++
*** Help mode now only makes hyperlinks for faces when the face name is
preceded or followed by the word `face'. It no longer makes
hyperlinks for variables without variable documentation, unless
addition, it now makes hyperlinks to URLs as well if the URL is
enclosed in single quotes and preceded by `URL'.
-+++
*** The new command `describe-char' (C-u C-x =) pops up a buffer with
description various information about a character, including its
encodings and syntax, its text properties, how to input, overlays, and
widgets at point. You can get more information about some of them, by
clicking on mouse-sensitive areas or moving there and pressing RET.
-+++
*** The command `list-text-properties-at' has been deleted because
C-u C-x = gives the same information and more.
-+++
*** New command `display-local-help' displays any local help at point
in the echo area. It is bound to `C-h .'. It normally displays the
same string that would be displayed on mouse-over using the
`help-echo' property, but, in certain cases, it can display a more
keyboard oriented alternative.
-+++
-*** New user option `help-at-pt-display-when-idle' allows to
+*** New user option `help-at-pt-display-when-idle' allows you to
automatically show the help provided by `display-local-help' on
point-over, after suitable idle time. The amount of idle time is
determined by the user option `help-at-pt-timer-delay' and defaults
to one second. This feature is turned off by default.
-+++
-*** The apropos commands now accept a list of words to match.
-When more than one word is specified, at least two of those words must
-be present for an item to match. Regular expression matching is still
-available.

-number calculated to indicate how well the item matches the words or
-regular expression that you entered to the apropos command. The best
-match is listed first, and the calculated score is shown for each

+*** A prefix argument is no longer required to repeat a jump to a
+previous mark if you set `set-mark-command-repeat-pop' to t. I.e. C-u
+C-SPC C-SPC C-SPC ... cycles through the mark ring. Use C-u C-u C-SPC
+to set the mark immediately after a jump.
+
+*** Marking commands extend the region when invoked multiple times.
+
+If you type C-M-SPC (mark-sexp), M-@ (mark-word), M-h
+(mark-paragraph), or C-M-h (mark-defun) repeatedly, the marked region

+
+With positive arg, M-h marks the current and the following paragraphs;
+if the arg is negative, it marks the current and the preceding
+paragraphs.
** Incremental Search changes:
-+++
-*** Vertical scrolling is now possible within incremental search.
-To enable this feature, customize the new user option
-`isearch-allow-scroll'. User written commands which satisfy stringent
-constraints can be marked as "scrolling commands". See the Emacs manual
-for details.
+*** M-% typed in isearch mode invokes `query-replace' or
+`query-replace-regexp' (depending on search mode) with the current
+search string used as the string to replace.
-+++
*** C-w in incremental search now grabs either a character or a word,
making the decision in a heuristic way. This new job is done by the
command `isearch-yank-word-or-char'. To restore the old behavior,
bind C-w to `isearch-yank-word' in `isearch-mode-map'.
-+++
*** C-y in incremental search now grabs the next line if point is already
at the end of a line.
-+++
*** C-M-w deletes and C-M-y grabs a character in isearch mode.
Another method to grab a character is to enter the minibuffer by `M-e'
and to type `C-f' at the end of the search string in the minibuffer.
-+++
-*** M-% typed in isearch mode invokes `query-replace' or
-`query-replace-regexp' (depending on search mode) with the current
-search string used as the string to replace.
+*** Vertical scrolling is now possible within incremental search.
+To enable this feature, customize the new user option
+`isearch-allow-scroll'. User written commands which satisfy stringent
+constraints can be marked as "scrolling commands". See the Emacs manual
+for details.
-+++
*** Isearch no longer adds `isearch-resume' commands to the command
history by default. To enable this feature, customize the new
user option `isearch-resume-in-command-history'.
** Replace command changes:
----
-*** New user option `query-replace-skip-read-only': when non-nil,
-`query-replace' and related functions simply ignore
-a match if part of it has a read-only property.
-
-+++
*** When used interactively, the commands `query-replace-regexp' and
`replace-regexp' allow \,expr to be used in a replacement string,
where expr is an arbitrary Lisp expression evaluated at replacement
-time. In many cases, this will be more convenient than using
-`query-replace-regexp-eval'. `\#' in a replacement string now refers
-to the count of replacements already made by the replacement command.
-All regular expression replacement commands now allow `\?' in the
-replacement string to specify a position where the replacement string
-can be edited for each replacement.

+string to specify a position where the replacement string can be
+edited for each replacement. `query-replace-regexp-eval' is now
+deprecated since it offers no additional functionality.
+
*** query-replace uses isearch lazy highlighting when the new user option
`query-replace-lazy-highlight' is non-nil.
----
*** The current match in query-replace is highlighted in new face
`query-replace' which by default inherits from isearch face.
-** Local variables lists:
-
-+++
-*** In processing a local variables list, Emacs strips the prefix and
-suffix from every line before processing all the lines.
-
-+++
-*** Text properties in local variables.
+*** New user option `query-replace-skip-read-only': when non-nil,
+`query-replace' and related functions simply ignore
+a match if part of it has a read-only property.
-A file local variables list cannot specify a string with text
-properties--any specified text properties are discarded.
+** Local variables lists:

*** If the local variables list contains any variable-value pairs that
are not known to be safe, Emacs shows a prompt asking whether to apply
the local variables list as a whole. In earlier versions, a prompt
However, risky variables will not be added to
`safe-local-variable-values' in this way.
-+++
*** The variable `enable-local-variables' controls how local variable
lists are handled. t, the default, specifies the standard querying
behavior. :safe means use only safe values, and ignore the rest.
:all means set all variables, whether or not they are safe.
nil means ignore them all. Anything else means always query.
-+++
*** The variable `safe-local-eval-forms' specifies a list of forms that
are ok to evaluate when they appear in an `eval' local variables
specification. Normally Emacs asks for confirmation before evaluating
such a form, but if the form appears in this list, no confirmation is
needed.
-+++
*** If a function has a non-nil `safe-local-eval-function' property,
that means it is ok to evaluate some calls to that function when it
appears in an `eval' local variables specification. If the property
If the form is not "ok to call", that means Emacs asks for
confirmation as before.

+
** File operation changes:
-+++
*** Unquoted `$' in file names do not signal an error any more when
the corresponding environment variable does not exist.
Instead, the `$ENVVAR' text is left as is, so that `$$' quoting
is only rarely needed.
-+++
-*** find-file-read-only visits multiple files in read-only mode,
-when the file name contains wildcard characters.
-
-+++
-*** find-alternate-file replaces the current file with multiple files,
-when the file name contains wildcard characters. It now asks if you
-wish save your changes and not just offer to kill the buffer.
-
-+++
-*** Auto Compression mode is now enabled by default.
-
----
*** C-x C-f RET, typing nothing in the minibuffer, is no longer a special case.
Since the default input is the current directory, this has the effect
of specifying the current directory. Normally that means to visit the
directory with Dired.
-+++
-*** When you are root, and you visit a file whose modes specify
-read-only, the Emacs buffer is now read-only too. Type C-x C-q if you
-want to make the buffer writable. (As root, you can in fact alter the
-file.)
-
-+++
*** C-x s (save-some-buffers) now offers an option `d' to diff a buffer
against its file, so you can see what changes you would be saving.
-+++
+*** Auto Compression mode is now enabled by default.
+
+*** If the user visits a file larger than `large-file-warning-threshold',
+Emacs asks for confirmation.
+
*** The commands copy-file, rename-file, make-symbolic-link and
add-name-to-file, when given a directory as the "new name" argument,
convert it to a file name by merging in the within-directory part of
commands cp, mv, and ln follow.) Thus, M-x copy-file RET ~/foo RET
/tmp RET copies ~/foo to /tmp/foo.
----
-*** When used interactively, `format-write-file' now asks for confirmation
-before overwriting an existing file, unless a prefix argument is
-supplied. This behavior is analogous to `write-file'.
-
----
-*** The variable `auto-save-file-name-transforms' now has a third element that
-controls whether or not the function `make-auto-save-file-name' will
-attempt to construct a unique auto-save name (e.g. for remote files).
-
-+++
-*** The new option `write-region-inhibit-fsync' disables calls to fsync
-in `write-region'. This can be useful on laptops to avoid spinning up
-the hard drive upon each file save. Enabling this variable may result
-in data loss, use with care.
-
-+++
-*** If the user visits a file larger than `large-file-warning-threshold',
-Emacs asks for confirmation.
-
-+++
*** require-final-newline now has two new possible values:
`visit' means add a newline (as an undoable change) if it's needed
needed when visiting the file, and also add a newline if it's needed
when saving the file.
-+++
*** The new option mode-require-final-newline controls how certain
major modes enable require-final-newline. Any major mode that's
designed for a kind of file that should normally end in a newline
So you can customize mode-require-final-newline to control what these
modes do.
+*** When you are root, and you visit a file whose modes specify

+
** Minibuffer changes:
-+++
+*** The completion commands TAB, SPC and ? in the minibuffer apply only
+to the text before point. If there is text in the buffer after point,
+it remains unchanged.
+
*** The new file-name-shadow-mode is turned ON by default, so that when
entering a file name, any prefix which Emacs will ignore is dimmed.
-+++
*** There's a new face `minibuffer-prompt'.
Emacs adds this face to the list of text properties stored in the
variable `minibuffer-prompt-properties', which is used to display the
prompt string.
----
*** Enhanced visual feedback in `*Completions*' buffer.
Completions lists use faces to highlight what all completions
the common prefix of completions to `display-completion-list' as
its second argument.
-+++
*** File-name completion can now ignore specified directories.
If an element of the list in `completion-ignored-extensions' ends in a
slash `/', it indicates a subdirectory that should be ignored when
which do not end in a slash are never considered when a completion
candidate is a directory.
-+++
-*** The completion commands TAB, SPC and ? in the minibuffer apply only
-to the text before point. If there is text in the buffer after point,
-it remains unchanged.
-
-+++
*** New user option `history-delete-duplicates'.
If set to t when adding a new history element, all previous identical
elements are deleted from the history list.
** Redisplay changes:
-+++
-*** Preemptive redisplay now adapts to current load and bandwidth.
-
-To avoid preempting redisplay on fast computers, networks, and displays,
-the arrival of new input is now performed at regular intervals during
-redisplay. The new variable `redisplay-preemption-period' specifies
-the period; the default is to check for input every 0.1 seconds.
-
-+++
-*** The mode line position information now comes before the major mode.
-When the file is maintained under version control, that information
-appears between the position information and the major mode.
-
-+++
-*** New face `escape-glyph' highlights control characters and escape glyphs.
-
-+++
-*** Non-breaking space and hyphens are now displayed with a special
-face, either nobreak-space or escape-glyph. You can turn this off or
-specify a different mode by setting the variable `nobreak-char-display'.
-
-+++
-*** The parameters of automatic hscrolling can now be customized.
-The variable `hscroll-margin' determines how many columns away from
-the window edge point is allowed to get before automatic hscrolling
-will horizontally scroll the window. The default value is 5.
-
-The variable `hscroll-step' determines how many columns automatic
-hscrolling scrolls the window when point gets too close to the
-window edge. If its value is zero, the default, Emacs scrolls the
-window so as to center point. If its value is an integer, it says how
-many columns to scroll. If the value is a floating-point number, it
-gives the fraction of the window's width to scroll the window.
-
-The variable `automatic-hscrolling' was renamed to
-`auto-hscroll-mode'. The old name is still available as an alias.
-
----
-*** Moving or scrolling through images (and other lines) taller than
-the window now works sensibly, by automatically adjusting the window's
-vscroll property.
-
-*** New customize option `overline-margin' controls the space between
-overline and text.
-
-*** New variable `x-underline-at-descent-line' controls the relative
-position of the underline. When set, it overrides the
-`x-use-underline-position-properties' variables.
-
-+++
*** The new face `mode-line-inactive' is used to display the mode line
of non-selected windows. The `mode-line' face is now used to display
the mode line of the currently selected window.
The new variable `mode-line-in-non-selected-windows' controls whether
the `mode-line-inactive' face is used.
-+++
+*** The mode line position information now comes before the major mode.
+When the file is maintained under version control, that information
+appears between the position information and the major mode.
+
*** You can now customize the use of window fringes. To control this
for all frames, use M-x fringe-mode or the Show/Hide submenu of the
top-level Options menu, or customize the `fringe-mode' variable. To
control this for a specific frame, use the command M-x
set-fringe-style.
-+++
*** Angle icons in the fringes can indicate the buffer boundaries. In
addition, up and down arrow bitmaps in the fringe indicate which ways
the window can be scrolled.
arrow bitmaps in right fringe. To show just the angle bitmaps in the
left fringe, but no arrow bitmaps, use ((top . left) (bottom . left)).
-+++
*** On window systems, lines which are exactly as wide as the window
(not counting the final newline character) are no longer broken into
two lines on the display (with just the newline on the second line).
The new user option 'overflow-newline-into-fringe' can be set to nil to
revert to the old behavior of continuing such lines.
-+++
-*** When a window has display margin areas, the fringes are now
-displayed between the margins and the buffer's text area, rather than
-outside those margins.
-
-+++
*** A window can now have individual fringe and scroll-bar settings,
in addition to the individual display margin settings.
horizontally or vertically, a saved window configuration is restored,
or when the frame is resized.

+*** When a window has display margin areas, the fringes are now
+displayed between the margins and the buffer's text area, rather than
+outside those margins.
+
+*** New face `escape-glyph' highlights control characters and escape glyphs.
+
+*** Non-breaking space and hyphens are now displayed with a special
+face, either nobreak-space or escape-glyph. You can turn this off or
+specify a different mode by setting the variable `nobreak-char-display'.
+
+*** The parameters of automatic hscrolling can now be customized.
+The variable `hscroll-margin' determines how many columns away from
+the window edge point is allowed to get before automatic hscrolling
+will horizontally scroll the window. The default value is 5.
+
+The variable `hscroll-step' determines how many columns automatic
+hscrolling scrolls the window when point gets too close to the
+window edge. If its value is zero, the default, Emacs scrolls the
+window so as to center point. If its value is an integer, it says how
+many columns to scroll. If the value is a floating-point number, it
+gives the fraction of the window's width to scroll the window.
+
+The variable `automatic-hscrolling' was renamed to
+`auto-hscroll-mode'. The old name is still available as an alias.
+
+*** Moving or scrolling through images (and other lines) taller than
+the window now works sensibly, by automatically adjusting the window's
+vscroll property.
+
+*** Preemptive redisplay now adapts to current load and bandwidth.
+
+To avoid preempting redisplay on fast computers, networks, and displays,
+the arrival of new input is now performed at regular intervals during
+redisplay. The new variable `redisplay-preemption-period' specifies
+the period; the default is to check for input every 0.1 seconds.
+
*** The %c and %l constructs are now ignored in frame-title-format.
Due to technical limitations in how Emacs interacts with windowing
systems, these constructs often failed to render properly, and could
even cause Emacs to crash.
-+++
*** If value of `auto-resize-tool-bars' is `grow-only', the tool bar
will expand as needed, but not contract automatically. To contract
the tool bar, you must type C-l.
-** Cursor display changes:
-
-+++
-*** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is
-now controlled by the variable `blink-cursor-alist'.
-
-+++
-*** The X resource cursorBlink can be used to turn off cursor blinking.
-
-+++
-*** Emacs can produce an underscore-like (horizontal bar) cursor.
-The underscore cursor is set by putting `(cursor-type . hbar)' in
-default-frame-alist. It supports variable heights, like the `bar'
-cursor does.
-
-+++
-*** Display of hollow cursors now obeys the buffer-local value (if any)
-of `cursor-in-non-selected-windows' in the buffer that the cursor
-appears in.
-
-+++
-*** The variable `cursor-in-non-selected-windows' can now be set to any
-of the recognized cursor types.
+*** New customize option `overline-margin' controls the space between
+overline and text.
-+++
-*** On text terminals, the variable `visible-cursor' controls whether Emacs
-uses the "very visible" cursor (the default) or the normal cursor.
+*** New variable `x-underline-at-descent-line' controls the relative
+position of the underline. When set, it overrides the
+`x-use-underline-position-properties' variables.
** New faces:
-+++
*** `mode-line-highlight' is the standard face indicating mouse sensitive
elements on mode-line (and header-line) like `highlight' face on text
areas.
*** `mode-line-buffer-id' is the standard face for buffer identification
parts of the mode line.
-+++
*** `shadow' face defines the appearance of the "shadowed" text, i.e.
the text which should be less noticeable than the surrounding text.
This can be achieved by using shades of grey in contrast with either
allows customization of the appearance of shadowed text in one place,
so package-specific faces can inherit from it.
-+++
*** `vertical-border' face is used for the vertical divider between windows.
-** ebnf2ps changes:
-
-+++
-*** New option `ebnf-arrow-extra-width' which specify extra width for arrow
-shape drawing.
-The extra width is used to avoid that the arrowhead and the terminal border
-overlap. It depens on `ebnf-arrow-shape' and `ebnf-line-width'.
-
-+++
-*** New option `ebnf-arrow-scale' which specify the arrow scale.
-Values lower than 1.0, shrink the arrow.
-Values greater than 1.0, expand the arrow.
-
-** Font-Lock changes:
-
-+++
-*** M-o now is the prefix key for setting text properties;
-M-o M-o requests refontification.
+** Font-Lock (syntax highlighting) changes:
-+++
*** All modes now support using M-x font-lock-mode to toggle
fontification, even those such as Occur, Info, and comint-derived
modes that do their own fontification in a special way.
fontification in Info, remove `turn-on-font-lock' from
`Info-mode-hook'.
-+++
-*** Font-Lock mode: in major modes such as Lisp mode, where some Emacs
-features assume that an open-paren in column 0 is always outside of
-any string or comment, Font-Lock now highlights any such open-paren in
-bold-red if it is inside a string or a comment, to indicate that it
-can cause trouble. You should rewrite the string or comment so that
-the open-paren is not in column 0.
+*** New standard font-lock face `font-lock-comment-delimiter-face'.
+This is used for the characters that indicate the start of a comment,
+e.g. `;' in Lisp mode.
-+++
*** New standard font-lock face `font-lock-preprocessor-face'.
-+++
-*** New standard font-lock face `font-lock-comment-delimiter-face'.
-
-+++
*** Easy to overlook single character negation can now be font-locked.
You can use the new variable `font-lock-negation-char-face' and the face of
the same name to customize this. Currently the cc-modes, sh-script-mode,
cperl-mode and make-mode support this.
----
+*** Font-Lock mode: in major modes such as Lisp mode, where some Emacs

+
+*** M-o now is the prefix key for setting text properties;
+M-o M-o requests refontification.
+
*** The default settings for JIT stealth lock parameters are changed.
The default value for the user option jit-lock-stealth-time is now nil
instead of 3. This setting of jit-lock-stealth-time disables stealth
jit-lock-stealth-nice is now 0.5 instead of 0.125 which is supposed to
cause less load than the old defaults.
----
*** jit-lock can now be delayed with `jit-lock-defer-time'.
If this variable is non-nil, its value should be the amount of Emacs
example, if you set `jit-lock-defer-time' to 0.25, fontification will
only happen after 0.25s of idle time.
----
*** contextual refontification is now separate from stealth fontification.
jit-lock-defer-contextually is renamed jit-lock-contextually and
jit-lock-context-time determines the delay after which contextual
refontification takes place.
----
*** lazy-lock is considered obsolete.
The `lazy-lock' package is superseded by `jit-lock' and is considered
obsolete. `jit-lock' is activated by default; if you wish to continue
using `lazy-lock', activate it in your ~/.emacs like this:
-
(setq font-lock-support-mode 'lazy-lock-mode)
If you invoke `lazy-lock-mode' directly rather than through
`font-lock-support-mode', it now issues a warning:
-
"Use font-lock-support-mode rather than calling lazy-lock-mode"
-
** Menu support:
----
*** A menu item "Show/Hide" was added to the top-level menu "Options".
This menu allows you to turn various display features on and off (such
as the fringes, the tool bar, the speedbar, and the menu bar itself).
it off completely. There is also a menu-item to toggle displaying of
current date and time, current line and column number in the mode-line.
----
*** Speedbar has moved from the "Tools" top level menu to "Show/Hide".
----
-*** You can exit dialog windows and menus by typing C-g.
-
----
*** The menu item "Open File..." has been split into two items, "New File..."
and "Open File...". "Open File..." now opens only existing files. This is
to support existing GUI file selection dialogs better.
-+++
-*** The file selection dialog for Gtk+, Mac, W32 and Motif/Lesstif can be
+*** The file selection dialog for Gtk+, Mac, W32 and Motif/LessTif can be
disabled by customizing the variable `use-file-dialog'.
----
*** The pop up menus for Lucid now stay up if you do a fast click and can
be navigated with the arrow keys (like Gtk+, Mac and W32).
-+++
-*** The menu bar for Motif/Lesstif/Lucid/Gtk+ can be navigated with keys.
+*** The menu bar for Motif/LessTif/Lucid/Gtk+ can be navigated with keys.
Pressing F10 shows the first menu in the menu bar. Navigation is done with
the arrow keys, select with the return key and cancel with the escape keys.
-+++
*** The Lucid menus can display multilingual text in your locale. You have
to explicitly specify a fontSet resource for this to work, for example
`-xrm "Emacs*fontSet: -*-helvetica-medium-r-*--*-120-*-*-*-*-*-*,*"'.
----
-*** Dialogs for Lucid/Athena and Lesstif/Motif now pops down when pressing
+*** Dialogs for Lucid/Athena and LessTif/Motif now pop down on pressing
ESC, like they do for Gtk+, Mac and W32.
-+++
*** For the Gtk+ version, you can make Emacs use the old file dialog
by setting the variable `x-gtk-use-old-file-dialog' to t. Default is to use
the new dialog.
-** Mouse changes:
+*** You can exit dialog windows and menus by typing C-g.
-+++
-*** If you set the new variable `mouse-autoselect-window' to a non-nil
-value, windows are automatically selected as you move the mouse from
-one Emacs window to another, even within a frame. A minibuffer window
-can be selected only when it is active.
+** Buffer Menu changes:
-+++
-*** On X, when the window manager requires that you click on a frame to
-select it (give it focus), the selected window and cursor position
-normally changes according to the mouse click position. If you set
-the variable x-mouse-click-focus-ignore-position to t, the selected
-window and cursor position do not change when you click on a frame
-to give it focus.
+*** The new options `buffers-menu-show-directories' and
+`buffers-menu-show-status' let you control how buffers are displayed
+in the menu dropped down when you click "Buffers" from the menu bar.
+
+`buffers-menu-show-directories' controls whether the menu displays
+leading directories as part of the file name visited by the buffer.
+If its value is `unless-uniquify', the default, directories are
+shown unless uniquify-buffer-name-style' is non-nil. The value of nil
+and t turn the display of directories off and on, respectively.
+
+`buffers-menu-show-status' controls whether the Buffers menu includes
+the modified and read-only status of the buffers. By default it is
+t, and the status is shown.
+
+Setting these variables directly does not take effect until next time
+the Buffers menu is regenerated.
+
+*** New command `Buffer-menu-toggle-files-only' toggles display of file
+buffers only in the Buffer Menu. It is bound to T in Buffer Menu
+mode.
+
+*** `buffer-menu' and `list-buffers' now list buffers whose names begin
+with a space, when those buffers are visiting files. Normally buffers
+whose names begin with space are omitted.
+
+** Mouse changes:
-+++
*** You can now follow links by clicking Mouse-1 on the link.
Traditionally, Emacs uses a Mouse-1 click to set point and a Mouse-2
click to follow a link, whereas most other applications use a Mouse-1
click for both purposes, depending on whether you click outside or
inside a link. Now the behavior of a Mouse-1 click has been changed
-to match this context-sentitive dual behavior. (If you prefer the old
+to match this context-sensitive dual behavior. (If you prefer the old
behavior, set the user option `mouse-1-click-follows-link' to nil.)
Depending on the current mode, a Mouse-2 click in Emacs can do much
You can customize the new Mouse-1 behavior via the new user options
`mouse-1-click-follows-link' and `mouse-1-click-in-non-selected-windows'.
-+++
+*** If you set the new variable `mouse-autoselect-window' to a non-nil
+value, windows are automatically selected as you move the mouse from
+one Emacs window to another, even within a frame. A minibuffer window
+can be selected only when it is active.
+
+*** On X, when the window manager requires that you click on a frame to
+select it (give it focus), the selected window and cursor position
+normally changes according to the mouse click position. If you set
+the variable x-mouse-click-focus-ignore-position to t, the selected
+window and cursor position do not change when you click on a frame
+to give it focus.
+
*** Emacs normally highlights mouse sensitive text whenever the mouse
is over the text. By setting the new variable `mouse-highlight', you
can optionally enable mouse highlighting only after you move the
mouse, so that highlighting disappears when you press a key. You can
also disable mouse highlighting.
-+++
*** You can now customize if selecting a region by dragging the mouse
shall not copy the selected text to the kill-ring by setting the new
variable mouse-drag-copy-region to nil.
----
-*** mouse-wheels can now scroll a specific fraction of the window
-(rather than a fixed number of lines) and the scrolling is `progressive'.
+*** Under X, mouse-wheel-mode is turned on by default.
----
*** Emacs ignores mouse-2 clicks while the mouse wheel is being moved.
People tend to push the mouse wheel (which counts as a mouse-2 click)
ignored. You can customize this with the mouse-wheel-click-event and
mouse-wheel-inhibit-click-time variables.
-+++
-*** Under X, mouse-wheel-mode is turned on by default.
+*** mouse-wheels can now scroll a specific fraction of the window
+(rather than a fixed number of lines) and the scrolling is `progressive'.
** Multilingual Environment (Mule) changes:
without any character translation:
;; -*- coding: iso-latin-1!; -*-
----
*** Language environment and various default coding systems are setup
more correctly according to the current locale name. If the locale
name doesn't specify a charset, the default is what glibc defines.
This change can result in using the different coding systems as
default in some locale (e.g. vi_VN).
-+++
*** The keyboard-coding-system is now automatically set based on your
current locale settings if you are not using a window system. This
can mean that the META key doesn't work but generates non-ASCII
or if the locale doesn't describe the character set actually generated
by the keyboard. See Info node `Unibyte Mode'.
-+++
-*** The new command `revert-buffer-with-coding-system' (C-x RET r)
+*** The new command `set-file-name-coding-system' (C-x RET F) sets
+coding system for encoding and decoding file names. A new menu item
+(Options->Mule->Set Coding Systems->For File Name) invokes this
+command.
+
+*** The new command `revert-buffer-with-coding-system' (C-x RET r)
revisits the current file using a coding system that you specify.
-+++
*** New command `recode-region' decodes the region again by a specified
coding system.
-+++
*** The new command `recode-file-name' changes the encoding of the name
of a file.
----
*** New command `ucs-insert' inserts a character specified by its
unicode.
-+++
-*** The new command `set-file-name-coding-system' (C-x RET F) sets
-coding system for encoding and decoding file names. A new menu item
-(Options->Mule->Set Coding Systems->For File Name) invokes this
-command.
-
-+++
*** New command quail-show-key shows what key (or key sequence) to type
in the current input method to input a character at point.
-+++
*** Limited support for character `unification' has been added.
Emacs now knows how to translate between different representations of
the same characters in various Emacs charsets according to standard
mule-unicode-0100-24ff charsets) on decoding. Note that this mode
will often effectively clobber data with an iso-2022 encoding.
----
-*** There is support for decoding Greek and Cyrillic characters into
-either Unicode (the mule-unicode charsets) or the iso-8859 charsets,
-when possible. The latter are more space-efficient. This is
-controlled by user option utf-fragment-on-decoding.

*** Improved Thai support. A new minor mode `thai-word-mode' (which is
automatically activated if you select Thai as a language
environment) changes key bindings of most word-oriented commands to
M-t (transpose-words)
M-q (fill-paragraph)

*** The utf-8/16 coding systems have been enhanced.
By default, untranslatable utf-8 sequences are simply composed into
single quasi-characters. User option `utf-translate-cjk-mode' (it is
one-dimensional internal charsets, specifically the ISO-8859 ones.
The utf-16 coding system is affected similarly.

*** A new coding system `euc-tw' has been added for traditional Chinese
in CNS encoding; it accepts both Big 5 and CNS as input; on saving,
Big 5 is then converted to CNS.
----
*** Many new coding systems are available in the `code-pages' library.
These include complete versions of most of those in codepage.el, based
on Unicode mappings. `codepage-setup' is now obsolete and is used
only in the MS-DOS port of Emacs. All coding systems defined in
`code-pages' are auto-loaded.
----
*** New variable `utf-translate-cjk-unicode-range' controls which
Unicode characters to translate in `utf-translate-cjk-mode'.
----
*** iso-10646-1 (`Unicode') fonts can be used to display any range of
characters encodable by the utf-8 coding system. Just specify the
fontset appropriately.
** Customize changes:
-+++
*** Custom themes are collections of customize options. Create a
custom theme with M-x customize-create-theme. Use M-x load-theme to
load and enable a theme, and M-x disable-theme to disable it. Use M-x
enable-theme to enable a disabled theme.
-+++
*** The commands M-x customize-face and M-x customize-face-other-window
now look at the character after point. If a face or faces are
specified for that character, the commands by default customize those
faces.
----
*** The face-customization widget has been reworked to be less confusing.
In particular, when you enable a face attribute using the corresponding
check-box, there's no longer a redundant `*' option in value selection
its check-box, then the (now ignored, but still present temporarily in
case you re-select the attribute) value is hidden.
-+++
*** When you set or reset a variable's value in a Customize buffer,
the previous value becomes the "backup value" of the variable.
You can go back to that backup value by selecting "Use Backup Value"
under the "[State]" button.
-** Buffer Menu changes:
-
-+++
-*** New command `Buffer-menu-toggle-files-only' toggles display of file
-buffers only in the Buffer Menu. It is bound to T in Buffer Menu
-mode.
-
-+++
-*** `buffer-menu' and `list-buffers' now list buffers whose names begin
-with a space, when those buffers are visiting files. Normally buffers
-whose names begin with space are omitted.
-
----
-*** The new options `buffers-menu-show-directories' and
-`buffers-menu-show-status' let you control how buffers are displayed
-in the menu dropped down when you click "Buffers" from the menu bar.
-
-`buffers-menu-show-directories' controls whether the menu displays
-leading directories as part of the file name visited by the buffer.
-If its value is `unless-uniquify', the default, directories are
-shown unless uniquify-buffer-name-style' is non-nil. The value of nil
-and t turn the display of directories off and on, respectively.
-
-`buffers-menu-show-status' controls whether the Buffers menu includes
-the modified and read-only status of the buffers. By default it is
-t, and the status is shown.
+** Dired mode:
-Setting these variables directly does not take effect until next time
-the Buffers menu is regenerated.
+*** In Dired's ! command (dired-do-shell-command), `*' and `?' now
+control substitution of the file names only when they are surrounded
+by whitespace. This means you can now use them as shell wildcards
+too. If you want to use just plain `*' as a wildcard, type `*""'; the
+double quotes make no difference in the shell, but they prevent
+special treatment in `dired-do-shell-command'.
-** Dired mode:
+*** The Dired command `dired-goto-file' is now bound to j, not M-g.
+This is to avoid hiding the global key binding of M-g.
----
*** New faces dired-header, dired-mark, dired-marked, dired-flagged,
dired-ignored, dired-directory, dired-symlink, dired-warning
introduced for Dired mode instead of font-lock faces.
-+++
*** New Dired command `dired-compare-directories' marks files
with different file attributes in two dired buffers.
-+++
*** New Dired command `dired-do-touch' (bound to T) changes timestamps
of marked files with the value entered in the minibuffer.
-+++
-*** The Dired command `dired-goto-file' is now bound to j, not M-g.
-This is to avoid hiding the global key binding of M-g.

-
-+++
*** In Dired, the w command now stores the current line's file name
into the kill ring. With a zero prefix arg, it stores the absolute file name.
-+++
*** In Dired-x, Omitting files is now a minor mode, dired-omit-mode.
The mode toggling command is bound to M-o. A new command
dired-omit-files-p is obsoleted, use the mode toggling function
instead.
-+++
*** The variables dired-free-space-program and dired-free-space-args
have been renamed to directory-free-space-program and
directory-free-space-args, and they now apply whenever Emacs puts a
** Comint changes:
----
+*** The new INSIDE_EMACS environment variable is set to "t" in subshells
+running inside Emacs. This supersedes the EMACS environment variable,
+which will be removed in a future Emacs release. Programs that need
+to know whether they are started inside Emacs should check INSIDE_EMACS
+instead of EMACS.
+
*** The comint prompt can now be made read-only, using the new user
option `comint-prompt-read-only'. This is not enabled by default,
except in IELM buffers. The read-only status of IELM prompts can be
`kill-region' if read-only properties are involved: it copies the text
to the kill-ring, but does not delete it.
-+++
*** The new command `comint-insert-previous-argument' in comint-derived
modes (shell-mode, etc.) inserts arguments from previous command lines,
like bash's `ESC .' binding. It is bound by default to `C-c .', but
otherwise behaves quite similarly to the bash version.
-+++
*** `comint-use-prompt-regexp-instead-of-fields' has been renamed
`comint-use-prompt-regexp'. The old name has been kept as an alias,
but declared obsolete.
-+++
-*** The new INSIDE_EMACS environment variable is set to "t" in
-subshells running inside Emacs. This supersedes the EMACS environment
-variable, which will be removed in a future Emacs release. Programs
-that need to know whether they are started inside Emacs should check
-INSIDE_EMACS instead of EMACS.
-
** M-x Compile changes:
----
*** M-x compile has become more robust and reliable
Quite a few more kinds of messages are recognized. Messages that are
The new file etc/compilation.txt gives examples of each type of message.
-+++
*** New user option `compilation-environment'.
This option allows you to specify environment variables for inferior
compilation processes without affecting the environment that all
subprocesses inherit.
-+++
*** New user option `compilation-disable-input'.
If this is non-nil, send end-of-file as compilation process input.
-+++
*** New options `next-error-highlight' and `next-error-highlight-no-select'
specify the method of highlighting of the corresponding source line
in new face `next-error'.
-+++
*** A new minor mode `next-error-follow-minor-mode' can be used in
compilation-mode, grep-mode, occur-mode, and diff-mode (i.e. all the
modes that can use `next-error'). In this mode, cursor motion in the
matches, compilation errors, etc. This minor mode can be toggled with
C-c C-f.
-+++
*** When the left fringe is displayed, an arrow points to current message in
the compilation buffer.
-+++
*** The new variable `compilation-context-lines' controls lines of leading
context before the current message. If nil and the left fringe is displayed,
it doesn't scroll the compilation output window. If there is no left fringe,
no arrow is displayed and a value of nil means display the message at the top
of the window.
-+++
-*** The EMACS environment variable now defaults to Emacs's absolute
-file name, instead of to "t".
-
** Occur mode changes:
-+++
-*** In the *Occur* buffer, `o' switches to it in another window, and
-C-o displays the current line's occurrence in another window without
-switching to it.
-
-+++
-*** You can now use next-error (C-x `) and previous-error to advance to
-the next/previous matching line found by M-x occur.
-
-+++
*** The new command `multi-occur' is just like `occur', except it can
search multiple buffers. There is also a new command
`multi-occur-in-matching-buffers' which allows you to specify the
Occur mode has been rewritten, and now uses font-lock, among other
changes.

+
** Grep changes:
-+++
*** Grep has been decoupled from compilation mode setup.
There's a new separate package grep.el, with its own submenu and
customization group.
-+++
*** `grep-find' is now also available under the name `find-grep' where
people knowing `find-grep-dired' would probably expect it.
-+++
*** New commands `lgrep' (local grep) and `rgrep' (recursive grep) are
more user-friendly versions of `grep' and `grep-find', which prompt
separately for the regular expression to match, the files to search,
-and the base directory for the search. Case sensitivitivy of the
+and the base directory for the search. Case sensitivity of the
search is controlled by the current value of `case-fold-search'.
These commands build the shell commands based on the new variables
typically used by various version control systems, like CVS and arch,
are automatically skipped by `rgrep'.
----
*** The grep commands provide highlighting support.
Hits are fontified in green, and hits in binary files in orange. Grep buffers
can be saved and automatically revisited.
----
-*** The new variables `grep-window-height' and `grep-scroll-output' override
-the corresponding compilation mode settings, for grep commands only.
-
-+++
*** New option `grep-highlight-matches' highlights matches in *grep*
buffer. It uses a special feature of some grep programs which accept
--color option to output markers around matches. When going to the next
buffer. Otherwise, if `grep-highlight-matches' is nil, the whole
source line is highlighted.
-+++
*** New key bindings in grep output window:
SPC and DEL scrolls window up and down. C-n and C-p moves to next and
previous match in the grep window. RET jumps to the source line of
previous or next file in the grep output. TAB also jumps to the next
file.
-+++
*** M-x grep now tries to avoid appending `/dev/null' to the command line
by using GNU grep `-H' option instead. M-x grep automatically
detects whether this is possible or not the first time it is invoked.
unchanged to the system to execute, which allows more complicated
command lines to be used than was possible before.
+*** The new variables `grep-window-height' and `grep-scroll-output' override
+the corresponding compilation mode settings, for grep commands only.
+
+** Cursor display changes:
+
+*** Emacs can produce an underscore-like (horizontal bar) cursor.
+The underscore cursor is set by putting `(cursor-type . hbar)' in
+default-frame-alist. It supports variable heights, like the `bar'
+cursor does.
+
+*** The variable `cursor-in-non-selected-windows' can now be set to any
+of the recognized cursor types.
+
+*** Display of hollow cursors now obeys the buffer-local value (if any)
+of `cursor-in-non-selected-windows' in the buffer that the cursor
+appears in.
+
+*** On text terminals, the variable `visible-cursor' controls whether Emacs
+uses the "very visible" cursor (the default) or the normal cursor.
+
+*** The X resource cursorBlink can be used to turn off cursor blinking.
+
+*** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is
+now controlled by the variable `blink-cursor-alist'.
+
** X Windows Support:
-+++
*** Emacs now supports drag and drop for X. Dropping a file on a window
- opens it, dropping text inserts the text. Dropping a file on a dired
- buffer copies or moves the file to that directory.
+opens it, dropping text inserts the text. Dropping a file on a dired
+buffer copies or moves the file to that directory.
-+++
*** Under X11, it is possible to swap Alt and Meta (and Super and Hyper).
The new variables `x-alt-keysym', `x-hyper-keysym', `x-meta-keysym',
and `x-super-keysym' can be used to choose which keysyms Emacs should
(setq x-alt-keysym 'meta)
(setq x-meta-keysym 'alt)
-+++
*** The X resource useXIM can be used to turn off use of XIM, which can
speed up Emacs with slow networking to the X server.
If the configure option `--without-xim' was used to turn off use of
XIM by default, the X resource useXIM can be used to turn it on.
----
*** The new variable `x-select-request-type' controls how Emacs
requests X selection. The default value is nil, which means that
Emacs requests X selection with types COMPOUND_TEXT and UTF8_STRING,
and use the more appropriately result.
----
*** The scrollbar under LessTif or Motif has a smoother drag-scrolling.
On the other hand, the size of the thumb does not represent the actual
amount of text shown any more (only a crude approximation of it).
** Xterm support:
----
*** If you enable Xterm Mouse mode, Emacs will respond to mouse clicks
on the mode line, header line and display margin, when run in an xterm.
----
*** Improved key bindings support when running in an xterm.
When Emacs is running in an xterm more key bindings are available.
The following should work:
** Character terminal color support changes:
-+++
*** The new command-line option --color=MODE lets you specify a standard
mode for a tty color support. It is meant to be used on character
terminals whose capabilities are not set correctly in the terminal
in "ls --color", it will support "emacs --color" as well. See the
user manual for the possible values of the MODE parameter.
----
*** Emacs now supports several character terminals which provide more
than 8 colors. For example, for `xterm', 16-color, 88-color, and
256-color modes are supported. Emacs automatically notes at startup
the extended number of colors, and defines the appropriate entries for
all of these colors.
-+++
*** Emacs now uses the full range of available colors for the default
faces when running on a color terminal, including 16-, 88-, and
256-color xterms. This means that when you run "emacs -nw" on an
88-color or 256-color xterm, you will see essentially the same face
colors as on X.
----
*** There's a new support for colors on `rxvt' terminal emulator.

* Changes in Specialized Modes and Packages in Emacs 22.1:
-** Changes in Shell Mode
-
-*** Shell output normally scrolls so that the input line is at the
-bottom of the window -- thus showing the maximum possible text. (This
-is similar to the way sequential output to a terminal works.)
-
** Changes in Dired
-+++
-*** Bindings for Tumme added
+*** Bindings for Image-Dired added.
Several new keybindings, all starting with the C-t prefix, have been
-added to Dired. They are all bound to commands in Tumme. As a starting
-point, mark some image files in a dired buffer and do C-t d to display
-thumbnails of them in a separate buffer.
+added to Dired. They are all bound to commands in Image-Dired. As a
+starting point, mark some image files in a dired buffer and do C-t d
+to display thumbnails of them in a separate buffer.
-** Changes in Hi Lock
+** Info mode changes
-+++
-*** hi-lock-mode now only affects a single buffer, and a new function
-`global-hi-lock-mode' enables Hi Lock in all buffers. By default, if
-hi-lock-mode is used in what appears to be the initialization file, a
-warning message suggests to use global-hi-lock-mode instead. However,
-if the new variable `hi-lock-archaic-interface-deduce' is non-nil,
-using hi-lock-mode in an initialization file will turn on Hi Lock in all
-buffers and no warning will be issued (for compatibility with the
-behavior in older versions of Emacs).
+*** Images in Info pages are supported.
----
-** Changes in Allout
+Info pages show embedded images, in Emacs frames with image support.
+Info documentation that includes images, processed with makeinfo
+version 4.7 or newer, compiles to Info pages with embedded images.
-*** Some previously rough topic-header format edge cases are reconciled.
-Level 1 topics use the mode's comment format, and lines starting with the
-asterisk - for instance, the comment close of some languages (eg, c's "*/"
-or mathematica's "*)") - at the beginning of line are no longer are
-interpreted as level 1 topics in those modes.
+*** `Info-index' offers completion.
-*** Many or most commonly occuring "accidental" topics are disqualified.
-Text in item bodies that looks like a low-depth topic is no longer mistaken
-for one unless its first offspring (or that of its next sibling with
-offspring) is only one level deeper.
+*** http and ftp links in Info are now operational: they look like cross
+references and following them calls `browse-url'.
-For example, pasting some text with a bunch of leading asterisks into a
-topic that's followed by a level 3 or deeper topic will not cause the
-pasted text to be mistaken for outline structure.
+*** isearch in Info uses Info-search and searches through multiple nodes.
-The same constraint is applied to any level 2 or 3 topics.
+Before leaving the initial Info node isearch fails once with the error
+message [initial node], and with subsequent C-s/C-r continues through
+other nodes. When isearch fails for the rest of the manual, it wraps
+around the whole manual to the top/final node. The user option
+`Info-isearch-search' controls whether to use Info-search for isearch,
+or the default isearch search function that wraps around the current
+Info node.
-This settles an old issue where typed or pasted text needed to be carefully
-reviewed, and sometimes doctored, to avoid accidentally disrupting the
-outline structure. Now that should be generally unnecessary, as the most
-prone-to-occur accidents are disqualified.
+*** New search commands: `Info-search-case-sensitively' (bound to S),
+`Info-search-backward', and `Info-search-next' which repeats the last
+search without prompting for a new search string.
-*** Allout now refuses to create "containment discontinuities", where a
-topic is shifted deeper than the offspring-depth of its container. On the
-other hand, allout now operates gracefully with existing containment
-discontinuities, revealing excessively contained topics rather than either
-leaving them hidden or raising an error.
+*** New command `info-apropos' searches the indices of the known
+Info files on your system for a string, and builds a menu of the
+possible matches.
-*** Topic cryptography added, enabling easy gpg topic encryption and
-decryption. Per-topic basis enables interspersing encrypted-text and
-clear-text within a single file to your heart's content, using symmetric
-and/or public key modes. Time-limited key caching, user-provided
-symmetric key hinting and consistency verification, auto-encryption of
-pending topics on save, and more, make it easy to use encryption in
-powerful ways. Encryption behavior customization is collected in the
-allout-encryption customization group.
+*** New command `Info-history-forward' (bound to r and new toolbar icon)
+moves forward in history to the node you returned from after using
+`Info-history-back' (renamed from `Info-last').
-*** Navigation within an item is easier. Repeated beginning-of-line and
-end-of-line key commands (usually, ^A and ^E) cycle through the
-beginning/end-of-line and then beginning/end of topic, etc. See new
-customization vars `allout-beginning-of-line-cycles' and
-`allout-end-of-line-cycles'.
+*** New command `Info-history' (bound to L) displays a menu of visited nodes.
-*** New or revised allout-mode activity hooks enable creation of
-cooperative enhancements to allout mode without changes to the mode,
-itself.
+*** New command `Info-toc' (bound to T) creates a node with table of contents
+from the tree structure of menus of the current Info file.
-See `allout-exposure-change-hook', `allout-structure-added-hook',
-`allout-structure-deleted-hook', and `allout-structure-shifted-hook'.
+*** New command `Info-copy-current-node-name' (bound to w) copies
+the current Info node name into the kill ring. With a zero prefix
+arg, puts the node name inside the `info' function call.
-`allout-exposure-change-hook' replaces the existing
-`allout-view-change-hook', which is being deprecated. Both are still
-invoked, but `allout-view-change-hook' will eventually be ignored.
-`allout-exposure-change-hook' is called with explicit arguments detailing
-the specifics of each change (as are the other new hooks), making it easier
+*** New face `info-xref-visited' distinguishes visited nodes from unvisited
+and a new option `Info-fontify-visited-nodes' to control this.
+
+*** A numeric prefix argument of `info' selects an Info buffer
+with the number appended to the `*info*' buffer name (e.g. "*info*<2>").
+
+*** Info now hides node names in menus and cross references by default.
+
+If you prefer the old behavior, you can set the new user option
+`Info-hide-note-references' to nil.
+
+*** The default value for `Info-scroll-prefer-subnodes' is now nil.
+
+** Emacs server changes
+
+*** You can have several Emacs servers on the same machine.
+
+ % emacs --eval '(setq server-name "foo")' -f server-start &
+ % emacs --eval '(setq server-name "bar")' -f server-start &
+ % emacsclient -s foo file1
+ % emacsclient -s bar file2
+
+*** The `emacsclient' command understands the options `--eval' and
+`--display' which tell Emacs respectively to evaluate the given Lisp
+expression and to use the given display when visiting files.
+
+*** User option `server-mode' can be used to start a server process.
+
+** Locate changes
+
+*** By default, reverting the *Locate* buffer now just runs the last
+`locate' command back over again without offering to update the locate
+database (which normally only works if you have root privileges). If
+you prefer the old behavior, set the new customizable option
+`locate-update-when-revert' to t.
+
+** Desktop package
+
+*** Desktop saving is now a minor mode, `desktop-save-mode'.
+
+*** The variable `desktop-enable' is obsolete.
+
+Customize `desktop-save-mode' to enable desktop saving.
+
+*** Buffers are saved in the desktop file in the same order as that in the
+buffer list.
+
+*** The desktop package can be customized to restore only some buffers
+immediately, remaining buffers are restored lazily (when Emacs is
+idle).
+
+*** New command line option --no-desktop
+
+*** New commands:
+ - desktop-revert reverts to the last loaded desktop.
+ - desktop-change-dir kills current desktop and loads a new.
+ - desktop-save-in-desktop-dir saves desktop in the directory from which
+ it was loaded.
+ - desktop-lazy-complete runs the desktop load to completion.
+ - desktop-lazy-abort aborts lazy loading of the desktop.
+
+*** New customizable variables:
+ - desktop-save. Determines whether the desktop should be saved when it is
+ killed.
+ - desktop-file-name-format. Format in which desktop file names should be saved.
+ - desktop-path. List of directories in which to lookup the desktop file.
+ - desktop-locals-to-save. List of local variables to save.
+ - desktop-globals-to-clear. List of global variables that `desktop-clear' will clear.
+ - desktop-clear-preserve-buffers-regexp. Regexp identifying buffers that `desktop-clear'
+ should not delete.
+ - desktop-restore-eager. Number of buffers to restore immediately. Remaining buffers are
+ restored lazily (when Emacs is idle).
+ - desktop-lazy-verbose. Verbose reporting of lazily created buffers.
+ - desktop-lazy-idle-delay. Idle delay before starting to create buffers.
+
+*** New hooks:
+ - desktop-after-read-hook run after a desktop is loaded.
+ - desktop-no-desktop-file-hook run when no desktop file is found.
+
+** Recentf changes
+
+The recent file list is now automatically cleaned up when recentf mode is
+enabled. The new option `recentf-auto-cleanup' controls when to do
+automatic cleanup.
+
+The ten most recent files can be quickly opened by using the shortcut
+keys 1 to 9, and 0, when the recent list is displayed in a buffer via
+the `recentf-open-files', or `recentf-open-more-files' commands.
+
+The `recentf-keep' option replaces `recentf-keep-non-readable-files-p'
+and provides a more general mechanism to customize which file names to
+keep in the recent list.
+
+With the more advanced option `recentf-filename-handlers', you can
+specify functions that successively transform recent file names. For
+example, if set to `file-truename' plus `abbreviate-file-name', the
+same file will not be in the recent list with different symbolic
+links, and the file name will be abbreviated.
+
+To follow naming convention, `recentf-menu-append-commands-flag'
+replaces the misnamed option `recentf-menu-append-commands-p'. The
+old name remains available as alias, but has been marked obsolete.
+
+** Auto-Revert changes
+
+*** You can now use Auto Revert mode to `tail' a file.
+
+If point is at the end of a file buffer before reverting, Auto Revert
+mode keeps it at the end after reverting. Similarly if point is
+displayed at the end of a file buffer in any window, it stays at the
+end of the buffer in that window. This allows you to "tail" a file:
+just put point at the end of the buffer and it stays there. This rule
+applies to file buffers. For non-file buffers, the behavior can be
+mode dependent.
+
+If you are sure that the file will only change by growing at the end,
+then you can tail the file more efficiently by using the new minor
+mode Auto Revert Tail mode. The function `auto-revert-tail-mode'
+toggles this mode.
+
+*** Auto Revert mode is now more careful to avoid excessive reverts and
+other potential problems when deciding which non-file buffers to
+revert. This matters especially if Global Auto Revert mode is enabled
+and `global-auto-revert-non-file-buffers' is non-nil. Auto Revert
+mode only reverts a non-file buffer if the buffer has a non-nil
+`revert-buffer-function' and a non-nil `buffer-stale-function', which
+decides whether the buffer should be reverted. Currently, this means
+that auto reverting works for Dired buffers (although this may not
+work properly on all operating systems) and for the Buffer Menu.
+
+*** If the new user option `auto-revert-check-vc-info' is non-nil, Auto
+Revert mode reliably updates version control info (such as the version
+control number in the mode line), in all version controlled buffers in
+which it is active. If the option is nil, the default, then this info
+only gets updated whenever the buffer gets reverted.
+
+** Changes in Shell Mode
+
+*** Shell output normally scrolls so that the input line is at the
+bottom of the window -- thus showing the maximum possible text. (This
+is similar to the way sequential output to a terminal works.)
+
+** Changes in Hi Lock
+
+*** hi-lock-mode now only affects a single buffer, and a new function
+`global-hi-lock-mode' enables Hi Lock in all buffers. By default, if
+hi-lock-mode is used in what appears to be the initialization file, a
+warning message suggests to use global-hi-lock-mode instead. However,
+if the new variable `hi-lock-archaic-interface-deduce' is non-nil,
+using hi-lock-mode in an initialization file will turn on Hi Lock in all
+buffers and no warning will be issued (for compatibility with the
+behavior in older versions of Emacs).
+
+** Changes in Allout
+
+*** Topic cryptography added, enabling easy gpg topic encryption and
+decryption. Per-topic basis enables interspersing encrypted-text and
+clear-text within a single file to your heart's content, using symmetric
+and/or public key modes. Time-limited key caching, user-provided
+symmetric key hinting and consistency verification, auto-encryption of
+pending topics on save, and more, make it easy to use encryption in
+powerful ways. Encryption behavior customization is collected in the
+allout-encryption customization group.
+
+*** Default command prefix was changed to "\C-c " (control-c space), to
+avoid intruding on user's keybinding space. Customize the
+`allout-command-prefix' variable to your preference.
+
+*** Some previously rough topic-header format edge cases are reconciled.
+Level 1 topics use the mode's comment format, and lines starting with the
+asterisk - for instance, the comment close of some languages (eg, c's "*/"
+or mathematica's "*)") - at the beginning of line are no longer are
+interpreted as level 1 topics in those modes.
+
+*** Many or most commonly occurring "accidental" topics are disqualified.
+Text in item bodies that looks like a low-depth topic is no longer mistaken
+for one unless its first offspring (or that of its next sibling with
+offspring) is only one level deeper.
+
+For example, pasting some text with a bunch of leading asterisks into a
+topic that's followed by a level 3 or deeper topic will not cause the
+pasted text to be mistaken for outline structure.
+
+The same constraint is applied to any level 2 or 3 topics.
+
+This settles an old issue where typed or pasted text needed to be carefully
+reviewed, and sometimes doctored, to avoid accidentally disrupting the
+outline structure. Now that should be generally unnecessary, as the most
+prone-to-occur accidents are disqualified.
+
+*** Allout now refuses to create "containment discontinuities", where a
+topic is shifted deeper than the offspring-depth of its container. On the
+other hand, allout now operates gracefully with existing containment
+discontinuities, revealing excessively contained topics rather than either
+leaving them hidden or raising an error.
+
+*** Navigation within an item is easier. Repeated beginning-of-line and
+end-of-line key commands (usually, ^A and ^E) cycle through the
+beginning/end-of-line and then beginning/end of topic, etc. See new
+customization vars `allout-beginning-of-line-cycles' and
+`allout-end-of-line-cycles'.
+
+*** New or revised allout-mode activity hooks enable creation of
+cooperative enhancements to allout mode without changes to the mode,
+itself.
+
+See `allout-exposure-change-hook', `allout-structure-added-hook',
+`allout-structure-deleted-hook', and `allout-structure-shifted-hook'.
+
+`allout-exposure-change-hook' replaces the existing
+`allout-view-change-hook', which is being deprecated. Both are still
+invoked, but `allout-view-change-hook' will eventually be ignored.
+`allout-exposure-change-hook' is called with explicit arguments detailing
+the specifics of each change (as are the other new hooks), making it easier
to use than the old version.
There is a new mode deactivation hook, `allout-mode-deactivate-hook', for
activation hook, `allout-mode-hook' are now run after the `allout-mode'
variable is changed, rather than before.
-*** Default command prefix was changed to "\C-c " (control-c space), to
-avoid intruding on user's keybinding space. Customize the
-`allout-command-prefix' variable to your preference.
-
*** Allout now uses text overlay's `invisible' property for concealed text,
instead of selective-display. This simplifies the code, in particular
avoiding the need for kludges for isearch dynamic-display, discretionary
- many, many other, more minor tweaks, fixes, and refinements.
- version number incremented to 2.2
-** The variable `woman-topic-at-point' was renamed
-to `woman-use-topic-at-point' and behaves differently: if this
-variable is non-nil, the `woman' command uses the word at point
-automatically, without asking for a confirmation. Otherwise, the word
-at point is suggested as default, but not inserted at the prompt.
+** Hideshow mode changes
+
+*** New variable `hs-set-up-overlay' allows customization of the overlay
+used to effect hiding for hideshow minor mode. Integration with isearch
+handles the overlay property `display' specially, preserving it during
+temporary overlay showing in the course of an isearch operation.
+
+*** New variable `hs-allow-nesting' non-nil means that hiding a block does
+not discard the hidden state of any "internal" blocks; when the parent
+block is later shown, the internal blocks remain hidden. Default is nil.
+
+** FFAP changes
+
+*** New ffap commands and keybindings:
+
+C-x C-r (`ffap-read-only'),
+C-x C-v (`ffap-alternate-file'), C-x C-d (`ffap-list-directory'),
+C-x 4 r (`ffap-read-only-other-window'), C-x 4 d (`ffap-dired-other-window'),
+C-x 5 r (`ffap-read-only-other-frame'), C-x 5 d (`ffap-dired-other-frame').
+
+*** FFAP accepts wildcards in a file name by default.
+
+C-x C-f passes the file name to `find-file' with non-nil WILDCARDS
+argument, which visits multiple files, and C-x d passes it to `dired'.
+
+** Changes in Skeleton
+
+*** In skeleton.el, `-' marks the `skeleton-point' without interregion interaction.
+
+`@' has reverted to only setting `skeleton-positions' and no longer
+sets `skeleton-point'. Skeletons which used @ to mark
+`skeleton-point' independent of `_' should now use `-' instead. The
+updated `skeleton-insert' docstring explains these new features along
+with other details of skeleton construction.
+
+*** The variables `skeleton-transformation', `skeleton-filter', and
+`skeleton-pair-filter' have been renamed to
+`skeleton-transformation-function', `skeleton-filter-function', and
+`skeleton-pair-filter-function'. The old names are still available
+as aliases.
+
+** HTML/SGML changes
+
+*** Emacs now tries to set up buffer coding systems for HTML/XML files
+automatically.
+
+*** SGML mode has indentation and supports XML syntax.
+The new variable `sgml-xml-mode' tells SGML mode to use XML syntax.
+When this option is enabled, SGML tags are inserted in XML style,
+i.e., there is always a closing tag.
+By default, its setting is inferred on a buffer-by-buffer basis
+from the file name or buffer contents.
+
+*** The variable `sgml-transformation' has been renamed to
+`sgml-transformation-function'. The old name is still available as
+alias.
+
+*** `xml-mode' is now an alias for `sgml-mode', which has XML support.
+
+** TeX modes
+
+*** New major mode Doctex mode, for *.dtx files.
+
+*** C-c C-c prompts for a command to run, and tries to offer a good default.
+
+*** The user option `tex-start-options-string' has been replaced
+by two new user options: `tex-start-options', which should hold
+command-line options to feed to TeX, and `tex-start-commands' which should hold
+TeX commands to use at startup.
+
+*** verbatim environments are now highlighted in courier by font-lock
+and super/sub-scripts are made into super/sub-scripts.
+
+** RefTeX mode changes
+
+*** Changes to RefTeX's table of contents
+
+The new command keys "<" and ">" in the TOC buffer promote/demote the
+section at point or all sections in the current region, with full
+support for multifile documents.
+
+The new command `reftex-toc-recenter' (`C-c -') shows the current
+section in the TOC buffer without selecting the TOC window.
+Recentering can happen automatically in idle time when the option
+`reftex-auto-recenter-toc' is turned on. The highlight in the TOC
+buffer stays when the focus moves to a different window. A dedicated
+frame can show the TOC with the current section always automatically
+highlighted. The frame is created and deleted from the toc buffer
+with the `d' key.
+
+The toc window can be split off horizontally instead of vertically.
+See new option `reftex-toc-split-windows-horizontally'.
+
+Labels can be renamed globally from the table of contents using the
+key `M-%'.
+
+The new command `reftex-goto-label' jumps directly to a label
+location.
+
+*** Changes related to citations and BibTeX database files
+
+Commands that insert a citation now prompt for optional arguments when
+called with a prefix argument. Related new options are
+`reftex-cite-prompt-optional-args' and `reftex-cite-cleanup-optional-args'.
+
+The new command `reftex-create-bibtex-file' creates a BibTeX database
+with all entries referenced in the current document. The keys "e" and
+"E" allow to produce a BibTeX database file from entries marked in a
+citation selection buffer.
+
+The command `reftex-citation' uses the word in the buffer before the
+cursor as a default search string.
+
+The support for chapterbib has been improved. Different chapters can
+now use BibTeX or an explicit `thebibliography' environment.
----
-** Changes to cmuscheme
+The macros which specify the bibliography file (like \bibliography)
+can be configured with the new option `reftex-bibliography-commands'.
-*** Emacs now offers to start Scheme if the user tries to
-evaluate a Scheme expression but no Scheme subprocess is running.
+Support for jurabib has been added.
-*** If the file ~/.emacs_NAME or ~/.emacs.d/init_NAME.scm (where NAME
-is the name of the Scheme interpreter) exists, its contents are sent
-to the Scheme subprocess upon startup.
+*** Global index matched may be verified with a user function.
-*** There are new commands to instruct the Scheme interpreter to trace
-procedure calls (`scheme-trace-procedure') and to expand syntactic forms
-(`scheme-expand-current-form'). The commands actually sent to the Scheme
-subprocess are controlled by the user options `scheme-trace-command',
-`scheme-untrace-command' and `scheme-expand-current-form'.
+During global indexing, a user function can verify an index match.
+See new option `reftex-index-verify-function'.
----
-** Changes in Makefile mode
+*** Parsing documents with many labels can be sped up.
-*** Makefile mode has submodes for automake, gmake, makepp, BSD make and imake.
+Operating in a document with thousands of labels can be sped up
+considerably by allowing RefTeX to derive the type of a label directly
+from the label prefix like `eq:' or `fig:'. The option
+`reftex-trust-label-prefix' needs to be configured in order to enable
+this feature. While the speed-up is significant, this may reduce the
+quality of the context offered by RefTeX to describe a label.
-The former two couldn't be differentiated before, and the latter three
-are new. Font-locking is robust now and offers new customizable
-faces.
+*** Miscellaneous changes
-*** The variable `makefile-query-one-target-method' has been renamed
-to `makefile-query-one-target-method-function'. The old name is still
-available as alias.
+The macros which input a file in LaTeX (like \input, \include) can be
+configured in the new option `reftex-include-file-commands'.
-+++
-** In Outline mode, `hide-body' no longer hides lines at the top
-of the file that precede the first header line.
+RefTeX supports global incremental search.
-+++
-** Telnet now prompts you for a port number with C-u M-x telnet.
+** BibTeX mode
----
-** The terminal emulation code in term.el has been improved; it can
-run most curses applications now.
+*** The new command `bibtex-url' browses a URL for the BibTeX entry at
+point (bound to C-c C-l and mouse-2, RET on clickable fields).
-+++
-** M-x diff uses Diff mode instead of Compilation mode.
+*** The new command `bibtex-entry-update' (bound to C-c C-u) updates
+an existing BibTeX entry by inserting fields that may occur but are not
+present.
-+++
-** Diff mode key bindings changed.
+*** New `bibtex-entry-format' option `required-fields', enabled by default.
-These are the new bindings:
+*** `bibtex-maintain-sorted-entries' can take values `plain',
+`crossref', and `entry-class' which control the sorting scheme used
+for BibTeX entries. `bibtex-sort-entry-class' controls the sorting
+scheme `entry-class'. TAB completion for reference keys and
+automatic detection of duplicates does not require anymore that
+`bibtex-maintain-sorted-entries' is non-nil.
-C-c C-e diff-ediff-patch (old M-A)
-C-c C-n diff-restrict-view (old M-r)
-C-c C-r diff-reverse-direction (old M-R)
-C-c C-u diff-context->unified (old M-U)
-C-c C-w diff-refine-hunk (old C-c C-r)
+*** The new command `bibtex-complete' completes word fragment before
+point according to context (bound to M-tab).
-To convert unified to context format, use C-u C-c C-u.
-In addition, C-c C-u now operates on the region
-in Transient Mark mode when the mark is active.
+*** In BibTeX mode the command `fill-paragraph' (M-q) fills
+individual fields of a BibTeX entry.
-+++
-** You can now customize `fill-nobreak-predicate' to control where
-filling can break lines. The value is now normally a list of
-functions, but it can also be a single function, for compatibility.
+*** The new variable `bibtex-autofill-types' contains a list of entry
+types for which fields are filled automatically (if possible).
-Emacs provide two predicates, `fill-single-word-nobreak-p' and
-`fill-french-nobreak-p', for use as the value of
-`fill-nobreak-predicate'.
+*** The new commands `bibtex-find-entry' and `bibtex-find-crossref'
+locate entries and crossref'd entries (bound to C-c C-s and C-c C-x).
+Crossref fields are clickable (bound to mouse-2, RET).
----
-** M-x view-file and commands that use it now avoid interfering
-with special modes such as Tar mode.
+*** The new variables `bibtex-files' and `bibtex-file-path' define a set
+of BibTeX files that are searched for entry keys.
----
-** Commands `winner-redo' and `winner-undo', from winner.el, are now
-bound to C-c <left> and C-c <right>, respectively. This is an
-incompatible change.
+*** The new command `bibtex-validate-globally' checks for duplicate keys
+in multiple BibTeX files.
----
-** `global-whitespace-mode' is a new alias for `whitespace-global-mode'.
+*** If the new variable `bibtex-autoadd-commas' is non-nil,
+automatically add missing commas at end of BibTeX fields.
-+++
-** M-x compare-windows now can automatically skip non-matching text to
-resync points in both windows.
+*** The new command `bibtex-copy-summary-as-kill' pushes summary
+of BibTeX entry to kill ring (bound to C-c C-t).
-+++
-** New user option `add-log-always-start-new-record'.
+*** If the new variable `bibtex-parse-keys-fast' is non-nil,
+use fast but simplified algorithm for parsing BibTeX keys.
-When this option is enabled, M-x add-change-log-entry always
-starts a new record regardless of when the last record is.
+*** The new variables bibtex-expand-strings and
+bibtex-autokey-expand-strings control the expansion of strings when
+extracting the content of a BibTeX field.
----
-** PO translation files are decoded according to their MIME headers
-when Emacs visits them.
+*** The variables `bibtex-autokey-name-case-convert' and
+`bibtex-autokey-titleword-case-convert' have been renamed to
+`bibtex-autokey-name-case-convert-function' and
+`bibtex-autokey-titleword-case-convert-function'. The old names are
+still available as aliases.
-** Info mode changes:
+** GUD changes
-+++
-*** A numeric prefix argument of `info' selects an Info buffer
-with the number appended to the `*info*' buffer name (e.g. "*info*<2>").
+*** The new package gdb-ui.el provides an enhanced graphical interface to
+GDB. You can interact with GDB through the GUD buffer in the usual way, but
+there are also further buffers which control the execution and describe the
+state of your program. It can separate the input/output of your program from
+that of GDB and watches expressions in the speedbar. It also uses features of
+Emacs 21/22 such as the toolbar, and bitmaps in the fringe to indicate
+breakpoints.
-+++
-*** isearch in Info uses Info-search and searches through multiple nodes.
+To use this package just type M-x gdb. See the Emacs manual if you want the
+old behaviour.
-Before leaving the initial Info node isearch fails once with the error
-message [initial node], and with subsequent C-s/C-r continues through
-other nodes. When isearch fails for the rest of the manual, it wraps
-around the whole manual to the top/final node. The user option
-`Info-isearch-search' controls whether to use Info-search for isearch,
-or the default isearch search function that wraps around the current
-Info node.
+*** GUD mode has its own tool bar for controlling execution of the inferior
+and other common debugger commands.
----
-*** New search commands: `Info-search-case-sensitively' (bound to S),
-`Info-search-backward', and `Info-search-next' which repeats the last
-search without prompting for a new search string.
+*** In GUD mode, when talking to GDB, C-x C-a C-j "jumps" the program
+counter to the specified source line (the one where point is).
-+++
-*** New command `Info-history-forward' (bound to r and new toolbar icon)
-moves forward in history to the node you returned from after using
-`Info-history-back' (renamed from `Info-last').
+*** The variable tooltip-gud-tips-p has been removed. GUD tooltips can now be
+toggled independently of normal tooltips with the minor mode
+`gud-tooltip-mode'.
----
-*** New command `Info-history' (bound to L) displays a menu of visited nodes.
+*** In graphical mode, with a C program, GUD Tooltips have been extended to
+display the #define directive associated with an identifier when program is
+not executing.
----
-*** New command `Info-toc' (bound to T) creates a node with table of contents
-from the tree structure of menus of the current Info file.
+*** GUD mode improvements for jdb:
-+++
-*** New command `info-apropos' searches the indices of the known
-Info files on your system for a string, and builds a menu of the
-possible matches.
+**** Search for source files using jdb classpath and class information.
+Fast startup since there is no need to scan all source files up front.
+There is also no need to create and maintain lists of source
+directories to scan. Look at `gud-jdb-use-classpath' and
+`gud-jdb-classpath' customization variables documentation.
----
-*** New command `Info-copy-current-node-name' (bound to w) copies
-the current Info node name into the kill ring. With a zero prefix
-arg, puts the node name inside the `info' function call.
+**** The previous method of searching for source files has been
+preserved in case someone still wants/needs to use it.
+Set `gud-jdb-use-classpath' to nil.
-+++
-*** New face `info-xref-visited' distinguishes visited nodes from unvisited
-and a new option `Info-fontify-visited-nodes' to control this.
+**** Supports the standard breakpoint (gud-break, gud-clear)
+set/clear operations from Java source files under the classpath, stack
+traversal (gud-up, gud-down), and run until current stack finish
+(gud-finish).
----
-*** http and ftp links in Info are now operational: they look like cross
-references and following them calls `browse-url'.
+**** Supports new jdb (Java 1.2 and later) in addition to oldjdb
+(Java 1.1 jdb).
-+++
-*** Info now hides node names in menus and cross references by default.
+*** Added jdb Customization Variables
-If you prefer the old behavior, you can set the new user option
-`Info-hide-note-references' to nil.
+**** `gud-jdb-command-name'. What command line to use to invoke jdb.
----
-*** Images in Info pages are supported.
+**** `gud-jdb-use-classpath'. Allows selection of java source file searching
+method: set to t for new method, nil to scan `gud-jdb-directories' for
+java sources (previous method).
-Info pages show embedded images, in Emacs frames with image support.
-Info documentation that includes images, processed with makeinfo
-version 4.7 or newer, compiles to Info pages with embedded images.
+**** `gud-jdb-directories'. List of directories to scan and search for Java
+classes using the original gud-jdb method (if `gud-jdb-use-classpath'
+is nil).
-+++
-*** The default value for `Info-scroll-prefer-subnodes' is now nil.
+*** Minor Improvements
----
-*** `Info-index' offers completion.
+**** The STARTTLS wrapper (starttls.el) can now use GNUTLS
+instead of the OpenSSL based `starttls' tool. For backwards
+compatibility, it prefers `starttls', but you can toggle
+`starttls-use-gnutls' to switch to GNUTLS (or simply remove the
+`starttls' tool).
-** Lisp mode changes:
+**** Do not allow debugger output history variable to grow without bounds.
+
+** Lisp mode changes
----
*** Lisp mode now uses `font-lock-doc-face' for doc strings.
-+++
*** C-u C-M-q in Emacs Lisp mode pretty-prints the list after point.
*** New features in evaluation commands
-+++
**** The function `eval-defun' (C-M-x) called on defface reinitializes
the face to the value specified in the defface expression.
-+++
**** Typing C-x C-e twice prints the value of the integer result
in additional formats (octal, hexadecimal, character) specified
by the new function `eval-expression-print-format'. The same
function also defines the result format for `eval-expression' (M-:),
`eval-print-last-sexp' (C-j) and some edebug evaluation functions.
-+++
-** CC mode changes.
+** Changes to cmuscheme
-*** The CC Mode manual has been extensively revised.
-The information about using CC Mode has been separated from the larger
-and more difficult chapters about configuration.
+*** Emacs now offers to start Scheme if the user tries to
+evaluate a Scheme expression but no Scheme subprocess is running.
-*** Changes in Key Sequences
-**** c-toggle-auto-hungry-state is no longer bound to C-c C-t.
+*** If the file ~/.emacs_NAME or ~/.emacs.d/init_NAME.scm (where NAME
+is the name of the Scheme interpreter) exists, its contents are sent
+to the Scheme subprocess upon startup.
-**** c-toggle-hungry-state is no longer bound to C-c C-d.
-This binding has been taken over by c-hungry-delete-forwards.
+*** There are new commands to instruct the Scheme interpreter to trace
+procedure calls (`scheme-trace-procedure') and to expand syntactic forms
+(`scheme-expand-current-form'). The commands actually sent to the Scheme
+subprocess are controlled by the user options `scheme-trace-command',
+`scheme-untrace-command' and `scheme-expand-current-form'.
-**** c-toggle-auto-state (C-c C-t) has been renamed to c-toggle-auto-newline.
-c-toggle-auto-state remains as an alias.
+** Ewoc changes
-**** The new commands c-hungry-backspace and c-hungry-delete-forwards
-have key bindings C-c C-DEL (or C-c DEL, for the benefit of TTYs) and
-C-c C-d (or C-c C-<delete> or C-c <delete>) respectively. These
-commands delete entire blocks of whitespace with a single
-key-sequence. [N.B. "DEL" is the <backspace> key.]
+*** The new function `ewoc-delete' deletes specified nodes.
-**** The new command c-toggle-electric-mode is bound to C-c C-l.
+*** `ewoc-create' now takes optional arg NOSEP, which inhibits insertion of
+a newline after each pretty-printed entry and after the header and footer.
+This allows you to create multiple-entry ewocs on a single line and to
+effect "invisible" nodes by arranging for the pretty-printer to not print
+anything for those nodes.
-**** The new command c-subword-mode is bound to C-c C-w.
+For example, these two sequences of expressions behave identically:
-*** C-c C-s (`c-show-syntactic-information') now highlights the anchor
-position(s).
+;; NOSEP nil
+(defun PP (data) (insert (format "%S" data)))
+(ewoc-create 'PP "start\n")
+
+;; NOSEP t
+(defun PP (data) (insert (format "%S\n" data)))
+(ewoc-create 'PP "start\n\n" "\n" t)
+
+** CC mode changes
+
+*** The CC Mode manual has been extensively revised.
+The information about using CC Mode has been separated from the larger
+and more difficult chapters about configuration.
*** New Minor Modes
**** Electric Minor Mode toggles the electric action of non-alphabetic keys.
letters in StudlyCapsIdentifiers. You enable this feature by C-c C-w. It can
also be used in non-CC Mode buffers. :-) Contributed by Masatake YAMATO.
-*** New clean-ups
+*** Support for the AWK language.
+Support for the AWK language has been introduced. The implementation is
+based around GNU AWK version 3.1, but it should work pretty well with
+any AWK. As yet, not all features of CC Mode have been adapted for AWK.
+Here is a summary:
+
+**** Indentation Engine
+The CC Mode indentation engine fully supports AWK mode.
+
+AWK mode handles code formatted in the conventional AWK fashion: `{'s
+which start actions, user-defined functions, or compound statements are
+placed on the same line as the associated construct; the matching `}'s
+are normally placed under the start of the respective pattern, function
+definition, or structured statement.
+
+The predefined line-up functions haven't yet been adapted for AWK
+mode, though some of them may work serendipitously. There shouldn't
+be any problems writing custom indentation functions for AWK mode.
+
+**** Font Locking
+There is a single level of font locking in AWK mode, rather than the
+three distinct levels the other modes have. There are several
+idiosyncrasies in AWK mode's font-locking due to the peculiarities of
+the AWK language itself.
-**** `comment-close-slash'.
-With this clean-up, a block (i.e. c-style) comment can be terminated by
-typing a slash at the start of a line.
+**** Comment and Movement Commands
+These commands all work for AWK buffers. The notion of "defun" has
+been augmented to include AWK pattern-action pairs - the standard
+"defun" commands on key sequences C-M-a, C-M-e, and C-M-h use this
+extended definition.
-**** `c-one-liner-defun'
-This clean-up compresses a short enough defun (for example, an AWK
-pattern/action pair) onto a single line. "Short enough" is configurable.
+**** "awk" style, Auto-newline Insertion and Clean-ups
+A new style, "awk" has been introduced, and this is now the default
+style for AWK code. With auto-newline enabled, the clean-up
+c-one-liner-defun (see above) is useful.
*** Font lock support.
CC Mode now provides font lock support for all its languages. This
All the keywords used in CORBA IDL, PSDL, and CIDL are recognized and
handled correctly, also wrt indentation.

*** New syntactic symbols in IDL mode.
The top level constructs "module" and "composition" (from CIDL) are
*** New function `c-context-open-line'.
It's the open-line equivalent of `c-context-line-break'.
+*** New clean-ups
+
+**** `comment-close-slash'.
+With this clean-up, a block (i.e. c-style) comment can be terminated by
+typing a slash at the start of a line.
+
+**** `c-one-liner-defun'
+This clean-up compresses a short enough defun (for example, an AWK
+pattern/action pair) onto a single line. "Short enough" is configurable.
+
*** New lineup functions
**** `c-lineup-string-cont'
**** `c-lineup-argcont'
Lines up continued function arguments after the preceding comma.
+*** Added toggle for syntactic indentation.
+The function `c-toggle-syntactic-indentation' can be used to toggle
+syntactic indentation.
+
*** Better caching of the syntactic context.
CC Mode caches the positions of the opening parentheses (of any kind)
of the lists surrounding the point. Those positions are used in many
Also, only the block and the closing line is indented; the current
line is left untouched.
-*** Added toggle for syntactic indentation.
-The function `c-toggle-syntactic-indentation' can be used to toggle
-syntactic indentation.
-
-** In sh-script, a continuation line is only indented if the backslash was
-preceded by a SPC or a TAB.
-
----
-** Perl mode has a new variable `perl-indent-continued-arguments'.
-
----
-** The old Octave mode bindings C-c f and C-c i have been changed
-to C-c C-f and C-c C-i. The C-c C-i subcommands now have duplicate
-bindings on control characters--thus, C-c C-i C-b is the same as
-C-c C-i b, and so on.
-
-** Fortran mode changes:
-
----
-*** Fortran mode does more font-locking by default. Use level 3
-highlighting for the old default.
-
-+++
-*** Fortran mode has a new variable `fortran-directive-re'.
-Adapt this to match the format of any compiler directives you use.
-Lines that match are never indented, and are given distinctive font-locking.
-
-+++
-*** F90 mode and Fortran mode have new navigation commands
-`f90-end-of-block', `f90-beginning-of-block', `f90-next-block',
-`f90-previous-block', `fortran-end-of-block',
-`fortran-beginning-of-block'.
-
----
-*** F90 mode and Fortran mode have support for `hs-minor-mode' (hideshow).
-It cannot deal with every code format, but ought to handle a sizeable
-majority.
-
----
-*** The new function `f90-backslash-not-special' can be used to change
-the syntax of backslashes in F90 buffers.
-
----
-** Reftex mode changes
-
-+++
-*** Changes to RefTeX's table of contents
-
-The new command keys "<" and ">" in the TOC buffer promote/demote the
-section at point or all sections in the current region, with full
-support for multifile documents.
-
-The new command `reftex-toc-recenter' (`C-c -') shows the current
-section in the TOC buffer without selecting the TOC window.
-Recentering can happen automatically in idle time when the option
-`reftex-auto-recenter-toc' is turned on. The highlight in the TOC
-buffer stays when the focus moves to a different window. A dedicated
-frame can show the TOC with the current section always automatically
-highlighted. The frame is created and deleted from the toc buffer
-with the `d' key.
-
-The toc window can be split off horizontally instead of vertically.
-See new option `reftex-toc-split-windows-horizontally'.
-
-Labels can be renamed globally from the table of contents using the
-key `M-%'.
-
-The new command `reftex-goto-label' jumps directly to a label
-location.
-
-+++
-*** Changes related to citations and BibTeX database files
-
-Commands that insert a citation now prompt for optional arguments when
-called with a prefix argument. Related new options are
-`reftex-cite-prompt-optional-args' and `reftex-cite-cleanup-optional-args'.
-
-The new command `reftex-create-bibtex-file' creates a BibTeX database
-with all entries referenced in the current document. The keys "e" and
-"E" allow to produce a BibTeX database file from entries marked in a
-citation selection buffer.
-
-The command `reftex-citation' uses the word in the buffer before the
-cursor as a default search string.
-
-The support for chapterbib has been improved. Different chapters can
-now use BibTeX or an explicit `thebibliography' environment.
-
-The macros which specify the bibliography file (like \bibliography)
-can be configured with the new option `reftex-bibliography-commands'.
-
-Support for jurabib has been added.
-
-+++
-*** Global index matched may be verified with a user function
-
-During global indexing, a user function can verify an index match.
-See new option `reftex-index-verify-function'.
-
-+++
-*** Parsing documents with many labels can be sped up.
-
-Operating in a document with thousands of labels can be sped up
-considerably by allowing RefTeX to derive the type of a label directly
-from the label prefix like `eq:' or `fig:'. The option
-`reftex-trust-label-prefix' needs to be configured in order to enable
-this feature. While the speed-up is significant, this may reduce the
-quality of the context offered by RefTeX to describe a label.
-
-+++
-*** Miscellaneous changes
-
-The macros which input a file in LaTeX (like \input, \include) can be
-configured in the new option `reftex-include-file-commands'.
-
-RefTeX supports global incremental search.
-
-+++
-** Prolog mode has a new variable `prolog-font-lock-keywords'
-to support use of font-lock.
-
-** HTML/SGML changes:
-
----
-*** Emacs now tries to set up buffer coding systems for HTML/XML files
-automatically.
-
-+++
-*** SGML mode has indentation and supports XML syntax.
-The new variable `sgml-xml-mode' tells SGML mode to use XML syntax.
-When this option is enabled, SGML tags are inserted in XML style,
-i.e., there is always a closing tag.
-By default, its setting is inferred on a buffer-by-buffer basis
-from the file name or buffer contents.
-
-*** The variable `sgml-transformation' has been renamed to
-`sgml-transformation-function'. The old name is still available as
-alias.
-
-+++
-*** `xml-mode' is now an alias for `sgml-mode', which has XML support.
-
-** TeX modes:
-
-+++
-*** C-c C-c prompts for a command to run, and tries to offer a good default.
-
-+++
-*** The user option `tex-start-options-string' has been replaced
-by two new user options: `tex-start-options', which should hold
-command-line options to feed to TeX, and `tex-start-commands' which should hold
-TeX commands to use at startup.
-
----
-*** verbatim environments are now highlighted in courier by font-lock
-and super/sub-scripts are made into super/sub-scripts.
-
-+++
-*** New major mode Doctex mode, for *.dtx files.
-
-** BibTeX mode:
-
-*** The new command `bibtex-url' browses a URL for the BibTeX entry at
-point (bound to C-c C-l and mouse-2, RET on clickable fields).
-
-*** The new command `bibtex-entry-update' (bound to C-c C-u) updates
-an existing BibTeX entry by inserting fields that may occur but are not
-present.
-
-*** New `bibtex-entry-format' option `required-fields', enabled by default.
-
-*** `bibtex-maintain-sorted-entries' can take values `plain',
-`crossref', and `entry-class' which control the sorting scheme used
-for BibTeX entries. `bibtex-sort-entry-class' controls the sorting
-scheme `entry-class'. TAB completion for reference keys and
-automatic detection of duplicates does not require anymore that
-`bibtex-maintain-sorted-entries' is non-nil.
-
-*** If the new variable `bibtex-parse-keys-fast' is non-nil,
-use fast but simplified algorithm for parsing BibTeX keys.
-
-*** If the new variable `bibtex-autoadd-commas' is non-nil,
-automatically add missing commas at end of BibTeX fields.
-
-*** The new variable `bibtex-autofill-types' contains a list of entry
-types for which fields are filled automatically (if possible).
+** Changes in Makefile mode
-*** The new command `bibtex-complete' completes word fragment before
-point according to context (bound to M-tab).
+*** Makefile mode has submodes for automake, gmake, makepp, BSD make and imake.
-*** The new commands `bibtex-find-entry' and `bibtex-find-crossref'
-locate entries and crossref'd entries (bound to C-c C-s and C-c C-x).
-Crossref fields are clickable (bound to mouse-2, RET).
+The former two couldn't be differentiated before, and the latter three
+are new. Font-locking is robust now and offers new customizable
+faces.
-*** In BibTeX mode the command `fill-paragraph' (M-q) fills
-individual fields of a BibTeX entry.
+*** The variable `makefile-query-one-target-method' has been renamed
+to `makefile-query-one-target-method-function'. The old name is still
+available as alias.
-*** The new variables `bibtex-files' and `bibtex-file-path' define a set
-of BibTeX files that are searched for entry keys.
+** Sql changes
-*** The new command `bibtex-validate-globally' checks for duplicate keys
-in multiple BibTeX files.
+*** The variable `sql-product' controls the highlighting of different
+SQL dialects. This variable can be set globally via Customize, on a
+buffer-specific basis via local variable settings, or for the current
+session using the new SQL->Product submenu. (This menu replaces the
+SQL->Highlighting submenu.)
-*** The new command `bibtex-copy-summary-as-kill' pushes summary
-of BibTeX entry to kill ring (bound to C-c C-t).
+The following values are supported:
-*** The new variables bibtex-expand-strings and
-bibtex-autokey-expand-strings control the expansion of strings when
-extracting the content of a BibTeX field.
+ ansi ANSI Standard (default)
+ db2 DB2
+ informix Informix
+ ingres Ingres
+ interbase Interbase
+ linter Linter
+ ms Microsoft
+ mysql MySQL
+ oracle Oracle
+ postgres Postgres
+ solid Solid
+ sqlite SQLite
+ sybase Sybase
-*** The variables `bibtex-autokey-name-case-convert' and
-`bibtex-autokey-titleword-case-convert' have been renamed to
-`bibtex-autokey-name-case-convert-function' and
-`bibtex-autokey-titleword-case-convert-function'. The old names are
-still available as aliases.
+The current product name will be shown on the mode line following the
+SQL mode indicator.
-** In Artist mode the variable `artist-text-renderer' has been
-renamed to `artist-text-renderer-function'. The old name is still
-available as alias.
+The technique of setting `sql-mode-font-lock-defaults' directly in
+your `.emacs' will no longer establish the default highlighting -- Use
+`sql-product' to accomplish this.
-+++
-** In Enriched mode, `set-left-margin' and `set-right-margin' are now
-by default bound to `C-c [' and `C-c ]' instead of the former `C-c C-l'
-and `C-c C-r'.
+ANSI keywords are always highlighted.
-** GUD changes:
+*** The function `sql-add-product-keywords' can be used to add
+font-lock rules to the product specific rules. For example, to have
+all identifiers ending in `_t' under MS SQLServer treated as a type,
+you would use the following line in your .emacs file:
-+++
-*** In GUD mode, when talking to GDB, C-x C-a C-j "jumps" the program
-counter to the specified source line (the one where point is).
+ (sql-add-product-keywords 'ms
+ '(("\\<\\w+_t\\>" . font-lock-type-face)))
----
-*** GUD mode has its own tool bar for controlling execution of the inferior
-and other common debugger commands.
+*** Oracle support includes keyword highlighting for Oracle 9i.
-+++
-*** The new package gdb-ui.el provides an enhanced graphical interface to
-GDB. You can interact with GDB through the GUD buffer in the usual way, but
-there are also further buffers which control the execution and describe the
-state of your program. It can separate the input/output of your program from
-that of GDB and watches expressions in the speedbar. It also uses features of
-Emacs 21/22 such as the toolbar, and bitmaps in the fringe to indicate
-breakpoints.
+Most SQL and PL/SQL keywords are implemented. SQL*Plus commands are
+highlighted in `font-lock-doc-face'.
-To use this package just type M-x gdb. See the Emacs manual if you want the
-old behaviour.
+*** Microsoft SQLServer support has been significantly improved.
-*** The variable tooltip-gud-tips-p has been removed. GUD tooltips can now be
-toggled independently of normal tooltips with the minor mode
-`gud-tooltip-mode'.
+Keyword highlighting for SqlServer 2000 is implemented.
+sql-interactive-mode defaults to use osql, rather than isql, because
+osql flushes its error stream more frequently. Thus error messages
+are displayed when they occur rather than when the session is
+terminated.
-+++
-*** In graphical mode, with a C program, GUD Tooltips have been extended to
-display the #define directive associated with an identifier when program is
-not executing.
+If the username and password are not provided to `sql-ms', osql is
+called with the `-E' command line argument to use the operating system
+credentials to authenticate the user.
----
-** GUD mode improvements for jdb:
+*** Postgres support is enhanced.
+Keyword highlighting of Postgres 7.3 is implemented. Prompting for
+the username and the pgsql `-U' option is added.
-*** Search for source files using jdb classpath and class information.
-Fast startup since there is no need to scan all source files up front.
-There is also no need to create and maintain lists of source
-directories to scan. Look at `gud-jdb-use-classpath' and
-`gud-jdb-classpath' customization variables documentation.
+*** MySQL support is enhanced.
+Keyword highlighting of MySql 4.0 is implemented.
-*** Supports the standard breakpoint (gud-break, gud-clear)
-set/clear operations from Java source files under the classpath, stack
-traversal (gud-up, gud-down), and run until current stack finish
-(gud-finish).
+*** Imenu support has been enhanced to locate tables, views, indexes,
+packages, procedures, functions, triggers, sequences, rules, and
+defaults.
-*** Supports new jdb (Java 1.2 and later) in addition to oldjdb
-(Java 1.1 jdb).
+*** Added SQL->Start SQLi Session menu entry which calls the
+appropriate `sql-interactive-mode' wrapper for the current setting of
+`sql-product'.
-*** The previous method of searching for source files has been
-preserved in case someone still wants/needs to use it.
-Set `gud-jdb-use-classpath' to nil.
+*** sql.el supports the SQLite interpreter--call 'sql-sqlite'.
-*** Added Customization Variables
+** Fortran mode changes
-**** `gud-jdb-command-name'. What command line to use to invoke jdb.
+*** F90 mode and Fortran mode have support for `hs-minor-mode' (hideshow).
+It cannot deal with every code format, but ought to handle a sizeable
+majority.
-**** `gud-jdb-use-classpath'. Allows selection of java source file searching
-method: set to t for new method, nil to scan `gud-jdb-directories' for
-java sources (previous method).
+*** F90 mode and Fortran mode have new navigation commands
+`f90-end-of-block', `f90-beginning-of-block', `f90-next-block',
+`f90-previous-block', `fortran-end-of-block',
+`fortran-beginning-of-block'.
-**** `gud-jdb-directories'. List of directories to scan and search for Java
-classes using the original gud-jdb method (if `gud-jdb-use-classpath'
-is nil).
+*** Fortran mode does more font-locking by default. Use level 3
+highlighting for the old default.
-*** Minor Improvements
+*** Fortran mode has a new variable `fortran-directive-re'.
+Adapt this to match the format of any compiler directives you use.
+Lines that match are never indented, and are given distinctive font-locking.
-**** The STARTTLS wrapper (starttls.el) can now use GNUTLS
-instead of the OpenSSL based `starttls' tool. For backwards
-compatibility, it prefers `starttls', but you can toggle
-`starttls-use-gnutls' to switch to GNUTLS (or simply remove the
-`starttls' tool).
+*** The new function `f90-backslash-not-special' can be used to change
+the syntax of backslashes in F90 buffers.
-**** Do not allow debugger output history variable to grow without bounds.
+** Miscellaneous programming mode changes
-** Auto-Revert changes:
+*** In sh-script, a continuation line is only indented if the backslash was
+preceded by a SPC or a TAB.
-+++
-*** You can now use Auto Revert mode to `tail' a file.
+*** Perl mode has a new variable `perl-indent-continued-arguments'.
-If point is at the end of a file buffer before reverting, Auto Revert
-mode keeps it at the end after reverting. Similarly if point is
-displayed at the end of a file buffer in any window, it stays at
-the end of the buffer in that window. This allows to tail a file:
-just put point at the end of the buffer and it stays there. This
-rule applies to file buffers. For non-file buffers, the behavior can
-be mode dependent.
+*** The old Octave mode bindings C-c f and C-c i have been changed
+to C-c C-f and C-c C-i. The C-c C-i subcommands now have duplicate
+bindings on control characters--thus, C-c C-i C-b is the same as
+C-c C-i b, and so on.
-If you are sure that the file will only change by growing at the end,
-then you can tail the file more efficiently by using the new minor
-mode Auto Revert Tail mode. The function `auto-revert-tail-mode'
-toggles this mode.
+*** Prolog mode has a new variable `prolog-font-lock-keywords'
+to support use of font-lock.
-+++
-*** Auto Revert mode is now more careful to avoid excessive reverts and
-other potential problems when deciding which non-file buffers to
-revert. This matters especially if Global Auto Revert mode is enabled
-and `global-auto-revert-non-file-buffers' is non-nil. Auto Revert
-mode only reverts a non-file buffer if the buffer has a non-nil
-`revert-buffer-function' and a non-nil `buffer-stale-function', which
-decides whether the buffer should be reverted. Currently, this means
-that auto reverting works for Dired buffers (although this may not
-work properly on all operating systems) and for the Buffer Menu.
+** VC Changes
-+++
-*** If the new user option `auto-revert-check-vc-info' is non-nil, Auto
-Revert mode reliably updates version control info (such as the version
-control number in the mode line), in all version controlled buffers in
-which it is active. If the option is nil, the default, then this info
-only gets updated whenever the buffer gets reverted.
+*** New backends for Subversion and Meta-CVS.
----
-** recentf changes.
+*** The new variable `vc-cvs-global-switches' specifies switches that
+are passed to any CVS command invoked by VC.
-The recent file list is now automatically cleaned up when recentf mode is
-enabled. The new option `recentf-auto-cleanup' controls when to do
-automatic cleanup.
+These switches are used as "global options" for CVS, which means they
+are inserted before the command name. For example, this allows you to
+specify a compression level using the `-z#' option for CVS.
-The ten most recent files can be quickly opened by using the shortcut
-keys 1 to 9, and 0, when the recent list is displayed in a buffer via
-the `recentf-open-files', or `recentf-open-more-files' commands.
+*** The key C-x C-q only changes the read-only state of the buffer
+(toggle-read-only). It no longer checks files in or out.
-The `recentf-keep' option replaces `recentf-keep-non-readable-files-p'
-and provides a more general mechanism to customize which file names to
-keep in the recent list.
+We made this change because we held a poll and found that many users
+were unhappy with the previous behavior. If you do prefer this
+behavior, you can bind `vc-toggle-read-only' to C-x C-q in your
+`.emacs' file:
-With the more advanced option `recentf-filename-handlers', you can
-specify functions that successively transform recent file names. For
-example, if set to `file-truename' plus `abbreviate-file-name', the
-same file will not be in the recent list with different symbolic
-links, and the file name will be abbreviated.
+ (global-set-key "\C-x\C-q" 'vc-toggle-read-only)
-To follow naming convention, `recentf-menu-append-commands-flag'
-replaces the misnamed option `recentf-menu-append-commands-p'. The
-old name remains available as alias, but has been marked obsolete.
+The function `vc-toggle-read-only' will continue to exist.
-+++
-** Desktop package
+*** VC-Annotate mode enhancements
-+++
-*** Desktop saving is now a minor mode, `desktop-save-mode'.
+In VC-Annotate mode, you can now use the following key bindings for
+enhanced functionality to browse the annotations of past revisions, or
+to view diffs or log entries directly from vc-annotate-mode:
-+++
-*** The variable `desktop-enable' is obsolete.
+ P: annotates the previous revision
+ N: annotates the next revision
+ J: annotates the revision at line
+ A: annotates the revision previous to line
+ D: shows the diff of the revision at line with its previous revision
+ L: shows the log of the revision at line
+ W: annotates the workfile (most up to date) version
-Customize `desktop-save-mode' to enable desktop saving.
+** pcl-cvs changes
----
-*** Buffers are saved in the desktop file in the same order as that in the
-buffer list.
+*** In pcl-cvs mode, there is a new `d y' command to view the diffs
+between the local version of the file and yesterday's head revision
+in the repository.
-+++
-*** The desktop package can be customized to restore only some buffers
-immediately, remaining buffers are restored lazily (when Emacs is
-idle).
+*** In pcl-cvs mode, there is a new `d r' command to view the changes
+anyone has committed to the repository since you last executed
+`checkout', `update' or `commit'. That means using cvs diff options
+-rBASE -rHEAD.
-+++
-*** New commands:
- - desktop-revert reverts to the last loaded desktop.
- - desktop-change-dir kills current desktop and loads a new.
- - desktop-save-in-desktop-dir saves desktop in the directory from which
- it was loaded.
- - desktop-lazy-complete runs the desktop load to completion.
- - desktop-lazy-abort aborts lazy loading of the desktop.
+** Diff changes
----
-*** New customizable variables:
- - desktop-save. Determines whether the desktop should be saved when it is
- killed.
- - desktop-file-name-format. Format in which desktop file names should be saved.
- - desktop-path. List of directories in which to lookup the desktop file.
- - desktop-locals-to-save. List of local variables to save.
- - desktop-globals-to-clear. List of global variables that `desktop-clear' will clear.
- - desktop-clear-preserve-buffers-regexp. Regexp identifying buffers that `desktop-clear'
- should not delete.
- - desktop-restore-eager. Number of buffers to restore immediately. Remaining buffers are
- restored lazily (when Emacs is idle).
- - desktop-lazy-verbose. Verbose reporting of lazily created buffers.
- - desktop-lazy-idle-delay. Idle delay before starting to create buffers.
+*** M-x diff uses Diff mode instead of Compilation mode.
-+++
-*** New command line option --no-desktop
+*** Diff mode key bindings changed.
----
-*** New hooks:
- - desktop-after-read-hook run after a desktop is loaded.
- - desktop-no-desktop-file-hook run when no desktop file is found.
+These are the new bindings:
----
-** The saveplace.el package now filters out unreadable files.
+C-c C-e diff-ediff-patch (old M-A)
+C-c C-n diff-restrict-view (old M-r)
+C-c C-r diff-reverse-direction (old M-R)
+C-c C-u diff-context->unified (old M-U)
+C-c C-w diff-refine-hunk (old C-c C-r)
-When you exit Emacs, the saved positions in visited files no longer
-include files that aren't readable, e.g. files that don't exist.
-Customize the new option `save-place-forget-unreadable-files' to nil
-to get the old behavior. The new options `save-place-save-skipped'
-and `save-place-skip-check-regexp' allow further fine-tuning of this
-feature.
+To convert unified to context format, use C-u C-c C-u.
+In addition, C-c C-u now operates on the region
+in Transient Mark mode when the mark is active.
** EDiff changes.
-+++
*** When comparing directories.
Typing D brings up a buffer that lists the differences between the contents of
directories. Now it is possible to use this buffer to copy the missing files
from one directory to another.
-+++
*** When comparing files or buffers.
Typing the = key now offers to perform the word-by-word comparison of the
currently highlighted regions in an inferior Ediff session. If you answer 'n'
then it reverts to the old behavior and asks the user to select regions for
comparison.
-+++
*** The new command `ediff-backup' compares a file with its most recent
backup using `ediff'. If you specify the name of a backup file,
`ediff-backup' compares it with the file of which it is a backup.
-+++
** Etags changes.
*** New regular expressions features
The --regex=@regexfile option means read the regexps from a file, one
per line. Lines beginning with space or tab are ignored.
-*** New language parsing features
+*** New language parsing features
+
+**** New language HTML.

-when `name=' is used inside an anchor and whenever `id=' is used.
+**** In C and derived languages, etags creates tags for #undef
**** In Makefiles, constants are tagged.
If you want the old behavior instead, thus avoiding to increase the
size of the tags file, use the --no-globals option.
-**** New language Lua.
-
-All functions are tagged.
-
**** In Perl, packages are tags.
Subroutine tags are named from their package. You can jump to sub tags
**** In Prolog, etags creates tags for rules in addition to predicates.
-**** New language PHP.
-
-Functions, classes and defines are tags. If the --members option is
-specified to etags, variables are tags also.
-
**** New default keywords for TeX.
The new keywords are def, newcommand, renewcommand, newenvironment and
renewenvironment.
-**** In C and derived languages, etags creates tags for #undef
-
*** Honor #line directives.
When Etags parses an input file that contains C preprocessor's #line
reads from standard input and marks the produced tags as belonging to
the file FILE.
-*** The --members option is now the default.
-
-Use --no-members if you want the old default behaviour of not tagging
-struct members in C, members variables in C++ and variables in PHP.
-
** Ctags changes.
*** Ctags now allows duplicate tags
-** VC Changes
-
-+++
-*** The key C-x C-q only changes the read-only state of the buffer
-(toggle-read-only). It no longer checks files in or out.
-
-We made this change because we held a poll and found that many users
-were unhappy with the previous behavior. If you do prefer this
-behavior, you can bind `vc-toggle-read-only' to C-x C-q in your
-`.emacs' file:
-
- (global-set-key "\C-x\C-q" 'vc-toggle-read-only)
-
-The function `vc-toggle-read-only' will continue to exist.
-
-+++
-*** The new variable `vc-cvs-global-switches' specifies switches that
-are passed to any CVS command invoked by VC.
-
-These switches are used as "global options" for CVS, which means they
-are inserted before the command name. For example, this allows you to

-*** VC-Annotate mode enhancements
-
-In VC-Annotate mode, you can now use the following key bindings for
-enhanced functionality to browse the annotations of past revisions, or

-
-** pcl-cvs changes:
-
-+++
-*** In pcl-cvs mode, there is a new `d y' command to view the diffs
-between the local version of the file and yesterday's head revision
-in the repository.
-
-+++
-*** In pcl-cvs mode, there is a new `d r' command to view the changes
-anyone has committed to the repository since you last executed
-`checkout', `update' or `commit'. That means using cvs diff options
--rBASE -rHEAD.
-
-+++
-** The new variable `mail-default-directory' specifies
-`default-directory' for mail buffers. This directory is used for
-auto-save files of mail buffers. It defaults to "~/".
-
-+++
-** The mode line can indicate new mail in a directory or file.
-
-See the documentation of the user option
-`display-time-mail-directory'.
-
-** Rmail changes:
-
----
-*** Rmail now displays 5-digit message ids in its summary buffer.
-
-*** The new commands rmail-end-of-message and rmail-summary end-of-message,
-by default bound to `/', go to the end of the current mail message in
-Rmail and Rmail summary buffers.
+** Rmail changes
-+++
*** Support for `movemail' from GNU mailutils was added to Rmail.

+This version of `movemail' allows you to read mail from a wide range of
mailbox formats, including remote POP3 and IMAP4 mailboxes with or
without TLS encryption. If GNU mailutils is installed on the system
and its version of `movemail' can be found in exec-path, it will be
used instead of the native one.
+*** The new commands rmail-end-of-message and rmail-summary end-of-message,
+by default bound to `/', go to the end of the current mail message in
+Rmail and Rmail summary buffers.
+
+*** Rmail now displays 5-digit message ids in its summary buffer.
+
** Gnus package
----
*** Gnus now includes Sieve and PGG
Sieve is a library for managing Sieve scripts. PGG is a library to handle
PGP/MIME.
----
*** There are many news features, bug fixes and improvements.
See the file GNUS-NEWS or the node "Oort Gnus" in the Gnus manual for details.
----
** MH-E changes.
Upgraded to MH-E version 8.0.3. There have been major changes since
version 5.0.2; see MH-E-NEWS for details.
-** Calendar changes:
+** Miscellaneous mail changes
-+++
-*** The meanings of C-x < and C-x > have been interchanged.
-< means to scroll backward in time, and > means to scroll forward.
+*** The new variable `mail-default-directory' specifies
+`default-directory' for mail buffers. This directory is used for
+auto-save files of mail buffers. It defaults to "~/".
-+++
-*** You can now use < and >, instead of C-x < and C-x >, to scroll
-the calendar left or right.
+*** The mode line can indicate new mail in a directory or file.
+
+See the documentation of the user option `display-time-mail-directory'.
+
+** Calendar changes
-+++
*** There is a new calendar package, icalendar.el, that can be used to
convert Emacs diary entries to/from the iCalendar format.
-+++
*** The new package cal-html.el writes HTML files with calendar and
diary entries.
-+++
+*** The new functions `diary-from-outlook', `diary-from-outlook-gnus',
+and `diary-from-outlook-rmail' can be used to import diary entries
+from Outlook-format appointments in mail messages. The variable
+`diary-outlook-formats' can be customized to recognize additional
+formats.
+
+*** The procedure for activating appointment reminders has changed:
+use the new function `appt-activate'. The new variable
+`appt-display-format' controls how reminders are displayed, replacing
+`appt-issue-message', `appt-visible', and `appt-msg-window'.
+
+*** The function `simple-diary-display' now by default sets a header line.
+This can be controlled through the variables `diary-header-line-flag'
+and `diary-header-line-format'.
+
*** Diary sexp entries can have custom marking in the calendar.
Diary sexp functions which only apply to certain days (such as
`diary-block' or `diary-cyclic') now take an optional parameter MARK,
face. This lets you have different colors or markings for vacations,
appointments, paydays or anything else using a sexp.
-+++
+*** The meanings of C-x < and C-x > have been interchanged.
+< means to scroll backward in time, and > means to scroll forward.
+
+*** You can now use < and >, instead of C-x < and C-x >, to scroll
+the calendar left or right.
+
*** The new function `calendar-goto-day-of-year' (g D) prompts for a
year and day number, and moves to that date. Negative day numbers
count backward from the end of the year.
-+++
*** The new Calendar function `calendar-goto-iso-week' (g w)
prompts for a year and a week number, and moves to the first
day of that ISO week.
----
-*** The new variable `calendar-minimum-window-height' affects the
-window generated by the function `generate-calendar-window'.
-
----
*** The functions `holiday-easter-etc' and `holiday-advent' now take
optional arguments, in order to only report on the specified holiday
rather than all. This makes customization of variables such as
`christian-holidays' simpler.
----
-*** The function `simple-diary-display' now by default sets a header line.
-This can be controlled through the variables `diary-header-line-flag'
-and `diary-header-line-format'.
-
-+++

-keymap.
-
*** The new command `speedbar-toggle-line-expansion', bound to SPC,
contracts or expands the line under the cursor.
respectively, expand and contract the line under cursor with all of
its descendents.
+*** The new user option `speedbar-use-tool-tips-flag', if non-nil,
+means to display tool-tips for speedbar items.
+
*** The new user option `speedbar-query-confirmation-method' controls
how querying is performed for file operations. A value of 'always
means to always query before file operations; 'none-but-delete means
speedbar was started from.) A number such as 1 or -1 means to pass
that number to `other-frame'.
-*** The new user option `speedbar-use-tool-tips-flag', if non-nil,
-means to display tool-tips for speedbar items.
+*** SPC and DEL are no longer bound to scroll up/down in the speedbar
+keymap.
*** The frame management code in speedbar.el has been split into a new
`dframe' library. Emacs Lisp code that makes use of the speedbar
`speedbar-update-speed' and `speedbar-navigating-speed' are also
obsolete; use `dframe-update-speed' instead.
----
-** sql changes.
-
-*** The variable `sql-product' controls the highlighting of different
-SQL dialects. This variable can be set globally via Customize, on a
-buffer-specific basis via local variable settings, or for the current
-session using the new SQL->Product submenu. (This menu replaces the
-SQL->Highlighting submenu.)
-
-The following values are supported:
-
- ansi ANSI Standard (default)
- db2 DB2
- informix Informix
- ingres Ingres
- interbase Interbase
- linter Linter
- ms Microsoft
- mysql MySQL
- oracle Oracle
- postgres Postgres
- solid Solid
- sqlite SQLite
- sybase Sybase
-
-The current product name will be shown on the mode line following the
-SQL mode indicator.
-
-The technique of setting `sql-mode-font-lock-defaults' directly in
-your `.emacs' will no longer establish the default highlighting -- Use
-`sql-product' to accomplish this.
-
-ANSI keywords are always highlighted.
-
-*** The function `sql-add-product-keywords' can be used to add
-font-lock rules to the product specific rules. For example, to have
-all identifiers ending in `_t' under MS SQLServer treated as a type,
-you would use the following line in your .emacs file:
-
- (sql-add-product-keywords 'ms
- '(("\\<\\w+_t\\>" . font-lock-type-face)))
-
-*** Oracle support includes keyword highlighting for Oracle 9i.
-
-Most SQL and PL/SQL keywords are implemented. SQL*Plus commands are
-highlighted in `font-lock-doc-face'.
-
-*** Microsoft SQLServer support has been significantly improved.
-
-Keyword highlighting for SqlServer 2000 is implemented.
-sql-interactive-mode defaults to use osql, rather than isql, because
-osql flushes its error stream more frequently. Thus error messages
-are displayed when they occur rather than when the session is
-terminated.
-
-If the username and password are not provided to `sql-ms', osql is
-called with the `-E' command line argument to use the operating system
-credentials to authenticate the user.
-
-*** Postgres support is enhanced.
-Keyword highlighting of Postgres 7.3 is implemented. Prompting for
-the username and the pgsql `-U' option is added.
+** battery.el changes
-*** MySQL support is enhanced.
-Keyword highlighting of MySql 4.0 is implemented.
+*** display-battery-mode replaces display-battery.
-*** Imenu support has been enhanced to locate tables, views, indexes,
-packages, procedures, functions, triggers, sequences, rules, and
-defaults.
+*** battery.el now works on recent versions of OS X.
-*** Added SQL->Start SQLi Session menu entry which calls the
-appropriate `sql-interactive-mode' wrapper for the current setting of
-`sql-product'.
+** Games
----
-*** sql.el supports the SQLite interpreter--call 'sql-sqlite'.
+*** The game `mpuz' is enhanced.
-** FFAP changes:
+`mpuz' now allows the 2nd factor not to have two identical digits. By
+default, all trivial operations involving whole lines are performed
+automatically. The game uses faces for better visual feedback.
-+++
-*** New ffap commands and keybindings:
+** Obsolete and deleted packages
-C-x C-r (`ffap-read-only'),
-C-x C-v (`ffap-alternate-file'), C-x C-d (`ffap-list-directory'),
-C-x 4 r (`ffap-read-only-other-window'), C-x 4 d (`ffap-dired-other-window'),
-C-x 5 r (`ffap-read-only-other-frame'), C-x 5 d (`ffap-dired-other-frame').
+*** fast-lock.el and lazy-lock.el are obsolete. Use jit-lock.el instead.
----
-*** FFAP accepts wildcards in a file name by default.
+*** iso-acc.el is now obsolete. Use one of the latin input methods instead.
-C-x C-f passes the file name to `find-file' with non-nil WILDCARDS
-argument, which visits multiple files, and C-x d passes it to `dired'.
+*** zone-mode.el is now obsolete. Use dns-mode.el instead.
----
-** Changes in Skeleton
+*** cplus-md.el has been deleted.
-*** In skeleton.el, `-' marks the `skeleton-point' without interregion interaction.
+** Miscellaneous
-`@' has reverted to only setting `skeleton-positions' and no longer
-sets `skeleton-point'. Skeletons which used @ to mark
-`skeleton-point' independent of `_' should now use `-' instead. The
-updated `skeleton-insert' docstring explains these new features along
-with other details of skeleton construction.
+*** The variable `woman-topic-at-point' is renamed
+to `woman-use-topic-at-point' and behaves differently: if this
+variable is non-nil, the `woman' command uses the word at point
+automatically, without asking for a confirmation. Otherwise, the word
+at point is suggested as default, but not inserted at the prompt.
-*** The variables `skeleton-transformation', `skeleton-filter', and
-`skeleton-pair-filter' have been renamed to
-`skeleton-transformation-function', `skeleton-filter-function', and
-`skeleton-pair-filter-function'. The old names are still available
-as aliases.
+*** You can now customize `fill-nobreak-predicate' to control where
+filling can break lines. The value is now normally a list of
+functions, but it can also be a single function, for compatibility.
----
-** Hideshow mode changes
+Emacs provide two predicates, `fill-single-word-nobreak-p' and
+`fill-french-nobreak-p', for use as the value of
+`fill-nobreak-predicate'.
-*** New variable `hs-set-up-overlay' allows customization of the overlay
-used to effect hiding for hideshow minor mode. Integration with isearch
-handles the overlay property `display' specially, preserving it during
-temporary overlay showing in the course of an isearch operation.
+*** M-x view-file and commands that use it now avoid interfering
+with special modes such as Tar mode.
-*** New variable `hs-allow-nesting' non-nil means that hiding a block does
-not discard the hidden state of any "internal" blocks; when the parent
-block is later shown, the internal blocks remain hidden. Default is nil.
+*** `global-whitespace-mode' is a new alias for `whitespace-global-mode'.
-+++
-** `hide-ifdef-mode' now uses overlays rather than selective-display
-to hide its text. This should be mostly transparent but slightly
-changes the behavior of motion commands like C-e and C-p.
+*** The saveplace.el package now filters out unreadable files.
+
+When you exit Emacs, the saved positions in visited files no longer
+include files that aren't readable, e.g. files that don't exist.
+Customize the new option `save-place-forget-unreadable-files' to nil
+to get the old behavior. The new options `save-place-save-skipped'
+and `save-place-skip-check-regexp' allow further fine-tuning of this
+feature.
----
-** `partial-completion-mode' now handles partial completion on directory names.
+*** Commands `winner-redo' and `winner-undo', from winner.el, are now
+bound to C-c <left> and C-c <right>, respectively. This is an
+incompatible change.
----
-** The type-break package now allows `type-break-file-name' to be nil
+*** The type-break package now allows `type-break-file-name' to be nil
and if so, doesn't store any data across sessions. This is handy if
you don't want the `.type-break' file in your home directory or are
annoyed by the need for interaction when you kill Emacs.
----
-** `ps-print' can now print characters from the mule-unicode charsets.
+*** `ps-print' can now print characters from the mule-unicode charsets.
Printing text with characters from the mule-unicode-* sets works with
`ps-print', provided that you have installed the appropriate BDF
fonts. See the file INSTALL for URLs where you can find these fonts.
----
-** New command `strokes-global-set-stroke-string'.
+*** New command `strokes-global-set-stroke-string'.
This is like `strokes-global-set-stroke', but it allows you to bind
the stroke directly to a string to insert. This is convenient for
using strokes as an input method.
-** Emacs server changes:
-
-+++
-*** You can have several Emacs servers on the same machine.
+*** In Outline mode, `hide-body' no longer hides lines at the top
+of the file that precede the first header line.
- % emacs --eval '(setq server-name "foo")' -f server-start &
- % emacs --eval '(setq server-name "bar")' -f server-start &
- % emacsclient -s foo file1
- % emacsclient -s bar file2
+*** `hide-ifdef-mode' now uses overlays rather than selective-display
+to hide its text. This should be mostly transparent but slightly
+changes the behavior of motion commands like C-e and C-p.
-+++
-*** The `emacsclient' command understands the options `--eval' and
-`--display' which tell Emacs respectively to evaluate the given Lisp
-expression and to use the given display when visiting files.
+*** In Artist mode the variable `artist-text-renderer' has been
+renamed to `artist-text-renderer-function'. The old name is still
+available as alias.
-+++
-*** User option `server-mode' can be used to start a server process.
+*** In Enriched mode, `set-left-margin' and `set-right-margin' are now
+by default bound to `C-c [' and `C-c ]' instead of the former `C-c C-l'
+and `C-c C-r'.
----
-** LDAP support now defaults to ldapsearch from OpenLDAP version 2.
+*** `partial-completion-mode' now handles partial completion on directory names.
-+++
-** You can now disable pc-selection-mode after enabling it.
+*** You can now disable pc-selection-mode after enabling it.
M-x pc-selection-mode behaves like a proper minor mode, and with no
argument it toggles the mode. Turning off PC-Selection mode restores
the global key bindings that were replaced by turning on the mode.

+*** `uniquify-strip-common-suffix' tells uniquify to prefer
`file|dir1' and `file|dir2' to `file|dir1/subdir' and `file|dir2/subdir'.
----
-** Support for `magic cookie' standout modes has been removed.
-
-Emacs still works on terminals that require magic cookies in order to
-use standout mode, but they can no longer display mode-lines in
-inverse-video.
-
----
-** The game `mpuz' is enhanced.
+*** New user option `add-log-always-start-new-record'.
-`mpuz' now allows the 2nd factor not to have two identical digits. By
-default, all trivial operations involving whole lines are performed
-automatically. The game uses faces for better visual feedback.
+When this option is enabled, M-x add-change-log-entry always
+starts a new record regardless of when the last record is.
-** battery.el changes:
+*** M-x compare-windows now can automatically skip non-matching text to
+resync points in both windows.
----
-*** display-battery-mode replaces display-battery.
+*** PO translation files are decoded according to their MIME headers
+when Emacs visits them.
----
-*** battery.el now works on recent versions of OS X.
+*** Telnet now prompts you for a port number with C-u M-x telnet.
----
-** calculator.el now has radix grouping mode.
+*** calculator.el now has radix grouping mode.
To enable this, set `calculator-output-radix' non-nil. In this mode a
separator character is used every few digits, making it easier to see
byte boundaries etc. For more info, see the documentation of the
variable `calculator-radix-grouping-mode'.

-** Ewoc changes
-
-*** The new function `ewoc-delete' deletes specified nodes.
-
-*** `ewoc-create' now takes optional arg NOSEP, which inhibits insertion of
-a newline after each pretty-printed entry and after the header and footer.
-This allows you to create multiple-entry ewocs on a single line and to
-effect "invisible" nodes by arranging for the pretty-printer to not print
-anything for those nodes.
-
-For example, these two sequences of expressions behave identically:
-
-;; NOSEP nil
-(defun PP (data) (insert (format "%S" data)))
-(ewoc-create 'PP "start\n")
+*** LDAP support now defaults to ldapsearch from OpenLDAP version 2.
-;; NOSEP t

-(ewoc-create 'PP "start\n\n" "\n" t)
+*** The terminal emulation code in term.el has been improved; it can
+run most curses applications now.
-** Locate changes
+*** Support for `magic cookie' standout modes has been removed.
----
-*** By default, reverting the *Locate* buffer now just runs the last
-`locate' command back over again without offering to update the locate
-database (which normally only works if you have root privileges). If
-you prefer the old behavior, set the new customizable option
-`locate-update-when-revert' to t.

* Changes in Emacs 22.1 on non-free operating systems
-+++
** The HOME directory defaults to Application Data under the user profile.
If you used a previous version of Emacs without setting the HOME
shared computers, and the default HOME directory is less likely to be
read-only on computers that are administered by someone else.
-+++
-** Passing resources on the command line now works on MS Windows.
-
-You can use --xrm to pass resource settings to Emacs, overriding any
-existing values. For example:
-
- emacs --xrm "Emacs.Background:red" --xrm "Emacs.Geometry:100x20"
-
-will start up Emacs on an initial frame of 100x20 with red background,
-irrespective of geometry or background setting on the Windows registry.
-
----
-** On MS Windows, the "system caret" now follows the cursor.
-
-This enables Emacs to work better with programs that need to track the
-cursor, for example screen magnifiers and text to speech programs.
-When such a program is in use, the system caret is made visible
-instead of Emacs drawing its own cursor. This seems to be required by
-some programs. The new variable w32-use-visible-system-caret allows
-the caret visibility to be manually toggled.
-
----
-** Tooltips now work on MS Windows.
-
-See the Emacs 21.1 NEWS entry for tooltips for details.
-
----
** Images are now supported on MS Windows.
PBM and XBM images are supported out of the box. Other image formats
zlib, and tiff depends on the version of jpeg that it was compiled
against. For additional information, see nt/INSTALL.
----
** Sound is now supported on MS Windows.
WAV format is supported on all versions of Windows, other formats such
Windows, or when other software provides hooks into the system level
sound support for those formats.
----
-** Different shaped mouse pointers are supported on MS Windows.
+** Tooltips now work on MS Windows.
-The mouse pointer changes shape depending on what is under the pointer.
+See the Emacs 21.1 NEWS entry for tooltips for details.
----
** Pointing devices with more than 3 buttons are now supported on MS Windows.
The new variable `w32-pass-extra-mouse-buttons-to-system' controls
whether Emacs should handle the extra buttons itself (the default), or
pass them to Windows to be handled with system-wide functions.
----
+** Passing resources on the command line now works on MS Windows.
+
+You can use --xrm to pass resource settings to Emacs, overriding any
+existing values. For example:

-** On MS Windows NT/W2K/XP, Emacs uses Unicode for clipboard operations.
-
-Those systems use Unicode internally, so this allows Emacs to share
-multilingual text with other applications. On other versions of
-MS Windows, Emacs now uses the appropriate locale coding-system, so
-the clipboard should work correctly for your local language without
-any customizations.
-
----
** Running in a console window in Windows now uses the console size.
Previous versions of Emacs erred on the side of having a usable Emacs
other than 80x25, you can still manually set
w32-use-full-screen-buffer to t.
----

* Incompatible Lisp Changes in Emacs 22.1
-+++
-** The `read-file-name' function now returns a null string if the
-user just types RET.
-
-+++
-** The function find-operation-coding-system may be called with a cons
-(FILENAME . BUFFER) in the second argument if the first argument
-OPERATION is `insert-file-contents', and thus a function registered in
-`file-coding-system-alist' is also called with such an argument.
-
----
-** The variables post-command-idle-hook and post-command-idle-delay have
-been removed. Use run-with-idle-timer instead.
-
-+++
-** `suppress-keymap' now works by remapping `self-insert-command' to
-the command `undefined'. (In earlier Emacs versions, it used
-`substitute-key-definition' to rebind self inserting characters to
-`undefined'.)
-
-+++
** Mode line display ignores text properties as well as the
:propertize and :eval forms in the value of a variable whose
`risky-local-variable' property is nil.
----
The function `comint-send-input' now accepts 3 optional arguments:
(comint-send-input &optional no-newline artificial)
argument `artificial' to a non-nil value, to prevent Emacs from
deleting the part of subprocess output that matches the input.
----
-** Support for Mocklisp has been removed.
-
-+++
-** The variable `memory-full' now remains t until
-there is no longer a shortage of memory.
+** The `read-file-name' function now returns a null string if the
+user just types RET.
-+++
-** When Emacs receives a USR1 or USR2 signal, this generates
-input events: sigusr1 or sigusr2. Use special-event-map to
-handle these events.
+** The variables post-command-idle-hook and post-command-idle-delay have
+been removed. Use run-with-idle-timer instead.
-+++
** A hex or octal escape in a string constant forces the string to
be multibyte or unibyte, respectively.
-+++
** The explicit method of creating a display table element by
combining a face number and a character code into a numeric
glyph code is deprecated.
`glyph-face' must be used to create and decode glyph codes in
display tables.
+** `suppress-keymap' now works by remapping `self-insert-command' to
+the command `undefined'. (In earlier Emacs versions, it used
+`substitute-key-definition' to rebind self inserting characters to
+`undefined'.)
+
+** The third argument of `accept-process-output' is now milliseconds.
+It used to be microseconds.
+
+** The function find-operation-coding-system may be called with a cons
+(FILENAME . BUFFER) in the second argument if the first argument
+OPERATION is `insert-file-contents', and thus a function registered in
+`file-coding-system-alist' is also called with such an argument.

\f
* Lisp Changes in Emacs 22.1
** General Lisp changes:
-*** The function `expt' handles negative exponents differently.
-The value for `(expt A B)', if both A and B are integers and B is
-negative, is now a float. For example: (expt 2 -2) => 0.25.
+*** New syntax: \s now stands for the SPACE character.
+
+`?\s' is a new way to write the space character. You must make sure
+it is not followed by a dash, since `?\s-...' indicates the "super"
+modifier. However, it would be strange to write a character constant
+and a following symbol (beginning with `-') with no space between
+them.
+
+`\s' stands for space in strings, too, but it is not really meant for
+strings; it is easier and nicer just to write a space.
+
+*** New syntax: \uXXXX and \UXXXXXXXX specify Unicode code points in hex.
+
+For instance, you can use "\u0428" to specify a string consisting of
+CYRILLIC CAPITAL LETTER SHA, or `"U0001D6E2" to specify one consisting
+of MATHEMATICAL ITALIC CAPITAL ALPHA (the latter is greater than
+#xFFFF and thus needs the longer syntax).
+
+This syntax works for both character constants and strings.
+
+*** New function `unsafep' determines whether a Lisp form is safe.
+
+It returns nil if the given Lisp form can't possibly do anything
+dangerous; otherwise it returns a reason why the form might be unsafe
+(calls unknown function, alters global variable, etc.).
-+++
*** The function `eql' is now available without requiring the CL package.
-+++
*** The new function `memql' is like `memq', but uses `eql' for comparison,
that is, floats are compared by value and other elements with `eq'.
-+++
+*** New functions `string-or-null-p' and `booleanp'.
+
+`string-or-null-p' returns non-nil if OBJECT is a string or nil.
+`booleanp' returns non-nil if OBJECT is t or nil.
+
*** `makehash' is now obsolete. Use `make-hash-table' instead.
-+++
+*** Minor change in the function `format'.
+
+Some flags that were accepted but not implemented (such as "*") are no
+longer accepted.
+
*** `add-to-list' takes an optional third argument, APPEND.
If APPEND is non-nil, the new element gets added at the end of the
list instead of at the beginning. This change actually occurred in
Emacs 21.1, but was not documented then.
-+++
*** New function `add-to-ordered-list' is like `add-to-list' but
associates a numeric ordering of each element added to the list.
-+++
+*** New function `add-to-history' adds an element to a history list.
+
+Lisp packages should use this function to add elements to their
+history lists.
+
+If `history-delete-duplicates' is non-nil, it removes duplicates of
+the new element from the history list it updates.
+
*** New function `copy-tree' makes a copy of a tree.
It recursively copies through both CARs and CDRs.
-+++
*** New function `delete-dups' deletes `equal' duplicate elements from a list.
It modifies the list destructively, like `delete'. Of several `equal'
occurrences of an element in the list, the one that's kept is the
first one.
-+++
-*** New function `add-to-history' adds an element to a history list.
-
-Lisp packages should use this function to add elements to their
-history lists.
-
-If `history-delete-duplicates' is non-nil, it removes duplicates of
-the new element from the history list it updates.
-
-+++
*** New function `rassq-delete-all'.
(rassq-delete-all VALUE ALIST) deletes, from ALIST, each element whose
CDR is `eq' to the specified value.
-+++
-*** The function `number-sequence' makes a list of equally-separated numbers.
-
-For instance, (number-sequence 4 9) returns (4 5 6 7 8 9). By
-default, the separation is 1, but you can specify a different
-separation as the third argument. (number-sequence 1.5 6 2) returns
-(1.5 3.5 5.5).
-
-+++
-*** New variables `most-positive-fixnum' and `most-negative-fixnum'.
-
-They hold the largest and smallest possible integer values.
-
-+++
-*** Minor change in the function `format'.
-
-Some flags that were accepted but not implemented (such as "*") are no
-longer accepted.
-
-+++
*** Functions `get' and `plist-get' no longer give errors for bad plists.
They return nil for a malformed property list or if the list is
cyclic.
-+++
*** New functions `lax-plist-get' and `lax-plist-put'.
They are like `plist-get' and `plist-put', except that they compare
the property name using `equal' rather than `eq'.
-+++
-*** New variable `print-continuous-numbering'.
+*** The function `number-sequence' makes a list of equally-separated numbers.
-When this is non-nil, successive calls to print functions use a single
-numbering scheme for circular structure references. This is only
-relevant when `print-circle' is non-nil.
+For instance, (number-sequence 4 9) returns (4 5 6 7 8 9). By
+default, the separation is 1, but you can specify a different
+separation as the third argument. (number-sequence 1.5 6 2) returns
+(1.5 3.5 5.5).
-When you bind `print-continuous-numbering' to t, you should
-also bind `print-number-table' to nil.
+*** New variables `most-positive-fixnum' and `most-negative-fixnum'.
-+++
-*** New function `macroexpand-all' expands all macros in a form.
+They hold the largest and smallest possible integer values.
-It is similar to the Common-Lisp function of the same name.
-One difference is that it guarantees to return the original argument
-if no expansion is done, which can be tested using `eq'.
+*** The function `expt' handles negative exponents differently.
+The value for `(expt A B)', if both A and B are integers and B is
+negative, is now a float. For example: (expt 2 -2) => 0.25.
-+++
*** The function `atan' now accepts an optional second argument.
When called with 2 arguments, as in `(atan Y X)', `atan' returns the
angle in radians between the vector [X, Y] and the X axis. (This is
equivalent to the standard C library function `atan2'.)
-+++
-*** A function or macro's doc string can now specify the calling pattern.
+*** New macro `with-case-table'
-You put this info in the doc string's last line. It should be
-formatted so as to match the regexp "\n\n(fn .*)\\'". If you don't
-specify this explicitly, Emacs determines it from the actual argument
-names. Usually that default is right, but not always.
+This executes the body with the case table temporarily set to a given
+case table.
-+++
*** New macro `with-local-quit' temporarily allows quitting.
A quit inside the body of `with-local-quit' is caught by the
This is for use around potentially blocking or long-running code
inside timer functions and `post-command-hook' functions.
-+++
*** New macro `define-obsolete-function-alias'.
This combines `defalias' and `make-obsolete'.
-+++
-*** New function `unsafep' determines whether a Lisp form is safe.
-
-It returns nil if the given Lisp form can't possibly do anything
-dangerous; otherwise it returns a reason why the form might be unsafe
-(calls unknown function, alters global variable, etc.).
-
-+++
*** New macro `eval-at-startup' specifies expressions to
evaluate when Emacs starts up. If this is done after startup,
it evaluates those expressions immediately.
This is useful in packages that can be preloaded.
-*** `list-faces-display' takes an optional argument, REGEXP.
+*** New function `macroexpand-all' expands all macros in a form.
-If it is non-nil, the function lists only faces matching this regexp.
+It is similar to the Common-Lisp function of the same name.
+One difference is that it guarantees to return the original argument
+if no expansion is done, which can be tested using `eq'.
-+++
-*** New functions `string-or-null-p' and `booleanp'.
+*** A function or macro's doc string can now specify the calling pattern.
+
+You put this info in the doc string's last line. It should be
+formatted so as to match the regexp "\n\n(fn .*)\\'". If you don't
+specify this explicitly, Emacs determines it from the actual argument
+names. Usually that default is right, but not always.
+
+*** New variable `print-continuous-numbering'.
-`string-or-null-p' returns non-nil iff OBJECT is a string or nil.
-`booleanp' returns non-nil iff OBJECT is t or nil.
+When this is non-nil, successive calls to print functions use a single
+numbering scheme for circular structure references. This is only
+relevant when `print-circle' is non-nil.
+
+When you bind `print-continuous-numbering' to t, you should
+also bind `print-number-table' to nil.
+
+*** `list-faces-display' takes an optional argument, REGEXP.
+
+If it is non-nil, the function lists only faces matching this regexp.
-+++
*** New hook `command-error-function'.
By setting this variable to a function, you can control
how the editor command loop shows the user an error message.
+*** `debug-on-entry' accepts primitive functions that are not special forms.
+
** Lisp code indentation features:
-+++
*** The `defmacro' form can contain indentation and edebug declarations.
These declarations specify how to indent the macro calls in Lisp mode
equivalent to writing a `def-edebug-spec' for the macro,
but this is cleaner.)
----
*** cl-indent now allows customization of Indentation of backquoted forms.
See the new user option `lisp-backquote-indentation'.
----
*** cl-indent now handles indentation of simple and extended `loop' forms.
The new user options `lisp-loop-keyword-indentation',
be used to customize the indentation of keywords and forms in loop
forms.
-+++
** Variable aliases:
*** New function: defvaralias ALIAS-VAR BASE-VAR [DOCSTRING]
DOCSTRING, if present, is the documentation for ALIAS-VAR; else it has
the same documentation as BASE-VAR.
+*** The macro `define-obsolete-variable-alias' combines `defvaralias' and
+`make-obsolete-variable'.
+
*** New function: indirect-variable VARIABLE
This function returns the variable at the end of the chain of aliases
It might be noteworthy that variables aliases work for all kinds of
variables, including buffer-local and frame-local variables.
-+++
-*** The macro `define-obsolete-variable-alias' combines `defvaralias' and
-`make-obsolete-variable'.
-
** defcustom changes:
-+++
*** The package-version keyword has been added to provide
`customize-changed-options' functionality to packages in the future.
Developers who make use of this keyword must also update the new
variable `customize-package-emacs-version-alist'.
-+++
*** The new customization type `float' requires a floating point number.
** String changes:
-+++
-*** The escape sequence \s is now interpreted as a SPACE character.
-
-Exception: In a character constant, if it is followed by a `-' in a
-character constant (e.g. ?\s-A), it is still interpreted as the super
-modifier. In strings, \s is always interpreted as a space.
-
-+++
*** A hex escape in a string constant forces the string to be multibyte.
-+++
*** An octal escape in a string constant forces the string to be unibyte.
-+++
+*** New function `string-to-multibyte' converts a unibyte string to a
+multibyte string with the same individual character codes.
+
*** `split-string' now includes null substrings in the returned list if
the optional argument SEPARATORS is non-nil and there are matches for
SEPARATORS at the beginning or end of the string. If SEPARATORS is
nil, or if the new optional third argument OMIT-NULLS is non-nil, all
empty matches are omitted from the returned list.
-+++
-*** New function `string-to-multibyte' converts a unibyte string to a
-multibyte string with the same individual character codes.
-
-+++
-*** New function `substring-no-properties' returns a substring without
-text properties.
-
-+++
*** The new function `assoc-string' replaces `assoc-ignore-case' and
`assoc-ignore-representation', which are still available, but have
been declared obsolete.
-+++
-*** New syntax: \uXXXX and \UXXXXXXXX specify Unicode code points in hex.
-Use "\u0428" to specify a string consisting of CYRILLIC CAPITAL LETTER SHA,
-or "\U0001D6E2" to specify one consisting of MATHEMATICAL ITALIC CAPITAL
-ALPHA (the latter is greater than #xFFFF and thus needs the longer
-syntax). Also available for characters.
+*** New function `substring-no-properties' returns a substring without
+text properties.
-+++
** Displaying warnings to the user.
See the functions `warn' and `display-warning', or the Lisp Manual.
facility is much better than using `message', since it displays
warnings in a separate window.
-+++
** Progress reporters.
These provide a simple and uniform way for commands to present
** Buffer positions:
-+++
*** Function `compute-motion' now calculates the usable window
width if the WIDTH argument is nil. If the TOPOS argument is nil,
the usable window height and width is used.
-+++
*** The `line-move', `scroll-up', and `scroll-down' functions will now
modify the window vscroll to scroll through display rows that are
taller that the height of the window, for example in the presence of
large images. To disable this feature, bind the new variable
`auto-window-vscroll' to nil.
-+++
*** The argument to `forward-word', `backward-word' is optional.
It defaults to 1.
-+++
*** Argument to `forward-to-indentation' and `backward-to-indentation' is optional.
It defaults to 1.
-+++
-*** New function `mouse-on-link-p' tests if a position is in a clickable link.
+*** `field-beginning' and `field-end' take new optional argument, LIMIT.
-This is the function used by the new `mouse-1-click-follows-link'
-functionality.
+This argument tells them not to search beyond LIMIT. Instead they
+give up and return LIMIT.
+
+*** New function `window-line-height' is an efficient way to get
+information about a specific text line in a window provided that the
+window's display is up-to-date.
-+++
*** New function `line-number-at-pos' returns the line number of a position.
It an optional buffer position argument that defaults to point.
-+++
-*** `field-beginning' and `field-end' take new optional argument, LIMIT.
-
-This argument tells them not to search beyond LIMIT. Instead they
-give up and return LIMIT.
-
-+++
*** Function `pos-visible-in-window-p' now returns the pixel coordinates
and partial visibility state of the corresponding row, if the PARTIALLY
arg is non-nil.
-+++
-*** New function `window-line-height' is an efficient way to get
-information about a specific text line in a window provided that the
-window's display is up-to-date.
-
-+++
*** New functions `posn-at-point' and `posn-at-x-y' return
click-event-style position information for a given visible buffer
position or for a given window pixel coordinate.
+*** New function `mouse-on-link-p' tests if a position is in a clickable link.
+
+This is the function used by the new `mouse-1-click-follows-link'
+functionality.
+
** Text modification:
-+++
*** The new function `buffer-chars-modified-tick' returns a buffer's
tick counter for changes to characters. Each time text in that buffer
is inserted or deleted, the character-change counter is updated to the
tick counter (`buffer-modified-tick'). Text property changes leave it
unchanged.
-+++
*** The new function `insert-for-yank' normally works like `insert', but
removes the text properties in the `yank-excluded-properties' list
and handles the `yank-handler' text property.
-+++
*** The new function `insert-buffer-substring-as-yank' is like
`insert-for-yank' except that it gets the text from another buffer as
in `insert-buffer-substring'.
-+++
*** The new function `insert-buffer-substring-no-properties' is like
`insert-buffer-substring', but removes all text properties from the
inserted substring.
-+++
*** The new function `filter-buffer-substring' extracts a buffer
substring, passes it through a set of filter functions, and returns
the filtered substring. Use it instead of `buffer-substring' or
`buffer-substring-filters' to remove soft newlines from the copied
text.
-+++
*** Function `translate-region' accepts also a char-table as TABLE
argument.
-+++
*** The new translation table `translation-table-for-input'
is used for customizing self-insertion. The character to
be inserted is translated through it.
----
*** Text clones.
The new function `text-clone-create'. Text clones are chunks of text
that are kept identical by transparently propagating changes from one
clone to the other.
----
*** The function `insert-string' is now obsolete.
** Filling changes.
-+++
*** In determining an adaptive fill prefix, Emacs now tries the function in
`adaptive-fill-function' _before_ matching the buffer line against
`adaptive-fill-regexp' rather than _after_ it.
-+++
** Atomic change groups.
To perform some changes in the current buffer "atomically" so that
** Buffer-related changes:
----
+*** The new function `buffer-local-value' returns the buffer-local
+binding of VARIABLE (a symbol) in buffer BUFFER. If VARIABLE does not
+have a buffer-local binding in buffer BUFFER, it returns the default
+value of VARIABLE instead.
+
*** `list-buffers-noselect' now takes an additional argument, BUFFER-LIST.
If it is non-nil, it specifies which buffers to list.
-+++
*** `kill-buffer-hook' is now a permanent local.
-+++
-*** The new function `buffer-local-value' returns the buffer-local
-binding of VARIABLE (a symbol) in buffer BUFFER. If VARIABLE does not
-have a buffer-local binding in buffer BUFFER, it returns the default
-value of VARIABLE instead.
-
*** The function `frame-or-buffer-changed-p' now lets you maintain
various status records in parallel.
for compatibility, an internal variable which exists only for this
purpose.
-+++
*** The function `read-buffer' follows the convention for reading from
the minibuffer with a default value: if DEF is non-nil, the minibuffer
prompt provided in PROMPT is edited to show the default value provided
** Searching and matching changes:
-+++
*** New function `looking-back' checks whether a regular expression matches
the text before point. Specifying the LIMIT argument bounds how far
back the match can start; this is a way to keep it from taking too long.
-+++
*** The new variable `search-spaces-regexp' controls how to search
for spaces in a regular expression. If it is non-nil, it should be a
regular expression, and any series of spaces stands for that regular
Spaces inside of constructs such as `[..]' and inside loops such as
`*', `+', and `?' are never replaced with `search-spaces-regexp'.
-+++
*** New regular expression operators, `\_<' and `\_>'.
These match the beginning and end of a symbol. A symbol is a
non-empty sequence of either word or symbol constituent characters, as
specified by the syntax table.
----
-*** rx.el has new corresponding `symbol-start' and `symbol-end' elements.
-
-+++
*** `skip-chars-forward' and `skip-chars-backward' now handle
character classes such as `[:alpha:]', along with individual
characters and ranges.
----
*** In `replace-match', the replacement text no longer inherits
properties from surrounding text.
-+++
*** The list returned by `(match-data t)' now has the buffer as a final
element, if the last match was on a buffer. `set-match-data'
accepts such a list for restoring the match state.
-+++
*** Functions `match-data' and `set-match-data' now have an optional
argument `reseat'. When non-nil, all markers in the match data list
passed to these functions will be reseated to point to nowhere.
-+++
+*** rx.el has new corresponding `symbol-start' and `symbol-end' elements.
+
*** The default value of `sentence-end' is now defined using the new
variable `sentence-end-without-space', which contains such characters
that end a sentence without following spaces.
** Undo changes:
-+++
*** `buffer-undo-list' allows programmable elements.
These elements have the form (apply FUNNAME . ARGS), where FUNNAME is
which indicates that the change which took place was limited to the
range BEG...END and increased the buffer size by DELTA.
-+++
*** If the buffer's undo list for the current command gets longer than
`undo-outer-limit', garbage collection empties it. This is to prevent
it from using up the available memory and choking Emacs.
-+++
-** New `yank-handler' text property can be used to control how
+** Killing and yanking changes:
+
+*** New `yank-handler' text property can be used to control how
previously killed text on the kill ring is reinserted.
The value of the `yank-handler' property must be a list with one to four
** Syntax table changes:
-+++
-*** The macro `with-syntax-table' no longer copies the syntax table.
+*** The new function `syntax-ppss' provides an efficient way to find the
+current syntactic context at point.
-+++
*** The new function `syntax-after' returns the syntax code
of the character after a specified buffer position, taking account
of text properties as well as the character code.
-+++
*** `syntax-class' extracts the class of a syntax code (as returned
by `syntax-after').
-+++
-*** The new function `syntax-ppss' provides an efficient way to find the
-current syntactic context at point.
+*** The macro `with-syntax-table' no longer copies the syntax table.
** File operation changes:
-+++
*** New vars `exec-suffixes' and `load-suffixes' used when
searching for an executable or an Emacs Lisp file.
-+++
-*** The new primitive `set-file-times' sets a file's access and
-modification times. Magic file name handlers can handle this
-operation.
+*** New function `locate-file' searches for a file in a list of directories.
+`locate-file' accepts a name of a file to search (a string), and two
+lists: a list of directories to search in and a list of suffixes to
+try; typical usage might use `exec-path' and `load-path' for the list
+of directories, and `exec-suffixes' and `load-suffixes' for the list
+of suffixes. The function also accepts a predicate argument to
+further filter candidate files.
+
+One advantage of using this function is that the list of suffixes in
+`exec-suffixes' is OS-dependant, so this function will find
+executables without polluting Lisp code with OS dependencies.
-+++
*** The new function `file-remote-p' tests a file name and returns
non-nil if it specifies a remote file (one that Emacs accesses using
its own special methods and not directly through the file system).
The value in that case is an identifier for the remote file system.
-+++
-*** `buffer-auto-save-file-format' is the new name for what was
-formerly called `auto-save-file-format'. It is now a permanent local.
-
-+++
-*** Functions `file-name-sans-extension' and `file-name-extension' now
-ignore the leading dots in file names, so that file names such as
-`.emacs' are treated as extensionless.
-
-+++
-*** `visited-file-modtime' and `calendar-time-from-absolute' now return
-a list of two integers, instead of a cons.
+*** The new hook `before-save-hook' is invoked by `basic-save-buffer'
+before saving buffers. This allows packages to perform various final
+tasks. For example, it can be used by the copyright package to make
+sure saved files have the current year in any copyright headers.
-+++
*** `file-chase-links' now takes an optional second argument LIMIT which
specifies the maximum number of links to chase through. If after that
many iterations the file name obtained is still a symbolic link,
`file-chase-links' returns it anyway.
-+++
-*** The new hook `before-save-hook' is invoked by `basic-save-buffer'
-before saving buffers. This allows packages to perform various final
-tasks. For example, it can be used by the copyright package to make
-sure saved files have the current year in any copyright headers.
+*** Functions `file-name-sans-extension' and `file-name-extension' now
+ignore the leading dots in file names, so that file names such as
+`.emacs' are treated as extensionless.
-+++
*** If `buffer-save-without-query' is non-nil in some buffer,
`save-some-buffers' will always save that buffer without asking (if
it's modified).
-+++
-*** New function `locate-file' searches for a file in a list of directories.
-`locate-file' accepts a name of a file to search (a string), and two
-lists: a list of directories to search in and a list of suffixes to
-try; typical usage might use `exec-path' and `load-path' for the list
-of directories, and `exec-suffixes' and `load-suffixes' for the list
-of suffixes. The function also accepts a predicate argument to
-further filter candidate files.
+*** `buffer-auto-save-file-format' is the new name for what was
+formerly called `auto-save-file-format'. It is now a permanent local.
-One advantage of using this function is that the list of suffixes in
-`exec-suffixes' is OS-dependant, so this function will find
-executables without polluting Lisp code with OS dependencies.
+*** `visited-file-modtime' and `calendar-time-from-absolute' now return
+a list of two integers, instead of a cons.
----
*** The precedence of file name handlers has been changed.
Instead of choosing the first handler that matches,
handler whose (match-beginning 0) is the largest is chosen. In case
of ties, the old "first matched" rule applies.
-+++
*** A file name handler can declare which operations it handles.
You do this by putting an `operation' property on the handler name
This is useful for autoloaded handlers, to prevent them from being
autoloaded when not really necessary.
-+++
*** The function `make-auto-save-file-name' is now handled by file
name handlers. This will be exploited for remote files mainly.
-+++
*** The function `file-name-completion' accepts an optional argument
PREDICATE, and rejects completion candidates that don't satisfy PREDICATE.
+*** The new primitive `set-file-times' sets a file's access and
+modification times. Magic file name handlers can handle this
+operation.
+
** Input changes:
-+++
+*** Functions `y-or-n-p', `read-char', `read-key-sequence' and the like, that
+display a prompt but don't use the minibuffer, now display the prompt
+using the text properties (esp. the face) of the prompt string.
+
*** The functions `read-event', `read-char', and `read-char-exclusive'
have a new optional argument SECONDS. If non-nil, this specifies a
maximum time to wait for input, in seconds. If no input arrives after
this time elapses, the functions stop waiting and return nil.
-+++
*** An interactive specification can now use the code letter `U' to get
the up-event that was discarded in case the last key sequence read for a
previous `k' or `K' argument was a down-event; otherwise nil is used.
-+++
*** The new interactive-specification `G' reads a file name
much like `F', but if the input is a directory name (even defaulted),
it returns just the directory name.
----
-*** Functions `y-or-n-p', `read-char', `read-key-sequence' and the like, that
-display a prompt but don't use the minibuffer, now display the prompt
-using the text properties (esp. the face) of the prompt string.
-
-+++
*** (while-no-input BODY...) runs BODY, but only so long as no input
arrives. If the user types or clicks anything, BODY stops as if a
quit had occurred. `while-no-input' returns the value of BODY, if BODY
finishes. It returns nil if BODY was aborted by a quit, and t if
BODY was aborted by arrival of input.
-+++
*** `recent-keys' now returns the last 300 keys.
** Minibuffer changes:
-+++
*** The new function `minibufferp' returns non-nil if its optional
buffer argument is a minibuffer. If the argument is omitted, it
defaults to the current buffer.
-+++
*** New function `minibuffer-selected-window' returns the window which
was selected when entering the minibuffer.
-+++
*** The `read-file-name' function now takes an additional argument which
specifies a predicate which the file name read must satisfy. The
new variable `read-file-name-predicate' contains the predicate argument
while reading the file name from the minibuffer; the predicate in this
variable is used by read-file-name-internal to filter the completion list.
----
*** The new variable `read-file-name-function' can be used by Lisp code
to override the built-in `read-file-name' function.
-+++
*** The new variable `read-file-name-completion-ignore-case' specifies
whether completion ignores case when reading a file name with the
`read-file-name' function.
-+++
*** The new function `read-directory-name' is for reading a directory name.
It is like `read-file-name' except that the defaulting works better
for directories, and completion inside it shows only directories.
-+++
*** The new variable `history-add-new-input' specifies whether to add new
elements in history. If set to nil, minibuffer reading functions don't
add new elements to the history list, so it is possible to do this
** Completion changes:
-+++
*** The new function `minibuffer-completion-contents' returns the contents
of the minibuffer just before point. That is what completion commands
operate on.
-+++
*** The functions `all-completions' and `try-completion' now accept lists
of strings as well as hash-tables additionally to alists, obarrays
and functions. Furthermore, the function `test-completion' is now
exported to Lisp. The keys in alists and hash tables can be either
strings or symbols, which are automatically converted with to strings.
-+++
*** The new macro `dynamic-completion-table' supports using functions
as a dynamic completion table.
minibuffer, FUN will be called in the buffer from which the minibuffer was
entered. `dynamic-completion-table' then computes the completion.
-+++
*** The new macro `lazy-completion-table' initializes a variable
as a lazy completion table.
from which the minibuffer was entered. The return value of
`lazy-completion-table' must be used to initialize the value of VAR.
-+++
-** Enhancements to keymaps.
+** Abbrev changes:
-*** New keymaps for typing file names
+*** `define-abbrev' now accepts an optional argument SYSTEM-FLAG.
-Two new keymaps, `minibuffer-local-filename-completion-map' and
-`minibuffer-local-must-match-filename-map', apply whenever
-Emacs reads a file name in the minibuffer. These key maps override
-the usual binding of SPC to `minibuffer-complete-word' (so that file
-names with embedded spaces could be typed without the need to quote
-the spaces).
+If non-nil, this marks the abbrev as a "system" abbrev, which means
+that it won't be stored in the user's abbrevs file if he saves the
+abbrevs. Major modes that predefine some abbrevs should always
+specify this flag.
+
+*** The new function `copy-abbrev-table' copies an abbrev table.
+
+It returns a new abbrev table that is a copy of a given abbrev table.
+
+** Enhancements to keymaps.
*** Cleaner way to enter key sequences.

command was not remapped.
+*** The definition of a key-binding passed to define-key can use XEmacs-style
+key-sequences, such as [(control a)].
+
+*** New keymaps for typing file names
+
+Two new keymaps, `minibuffer-local-filename-completion-map' and
+`minibuffer-local-must-match-filename-map', apply whenever
+Emacs reads a file name in the minibuffer. These key maps override
+the usual binding of SPC to `minibuffer-complete-word' (so that file
+names with embedded spaces could be typed without the need to quote
+the spaces).
+
+*** New function `current-active-maps' returns a list of currently
+active keymaps.
+
+*** New function `describe-buffer-bindings' inserts the list of all
+defined keys and their definitions.
+
+*** New function `keymap-prompt' returns the prompt string of a keymap.
+
*** If text has a `keymap' property, that keymap takes precedence
over minor mode keymaps.

possible to specify it with an optional argument explicitly.
-*** Dense keymaps now handle inheritance correctly.
-
-Previously a dense keymap would hide all of the simple-char key
-bindings of the parent keymap.
-
*** `define-key-after' now accepts keys longer than 1.
-*** New function `current-active-maps' returns a list of currently
-active keymaps.
-
-*** New function `describe-buffer-bindings' inserts the list of all
-defined keys and their definitions.

-** Abbrev changes:
-
-+++
-*** The new function `copy-abbrev-table' copies an abbrev table.
-
-It returns a new abbrev table that is a copy of a given abbrev table.

-+++
-*** `define-abbrev' now accepts an optional argument SYSTEM-FLAG.

-+++
** Enhancements to process support
-*** Function `list-processes' now has an optional argument; if non-nil,
-it lists only the processes whose query-on-exit flag is set.
-
-*** New fns `set-process-query-on-exit-flag' and `process-query-on-exit-flag'.
-
-These replace the old function `process-kill-without-query'. That
-function is still supported, but new code should use the new
-functions.
+*** Adaptive read buffering of subprocess output.
-*** Function `signal-process' now accepts a process object or process
-name in addition to a process id to identify the signaled process.
+On some systems, when Emacs reads the output from a subprocess, the
+output data is read in very small blocks, potentially resulting in
+very poor performance. This behavior can be remedied to some extent
+by setting the new variable `process-adaptive-read-buffering' to a
+non-nil value (the default), as it will automatically delay reading
+from such processes, allowing them to produce more output before
+Emacs tries to read it.
*** Processes now have an associated property list where programs can
maintain process state and other per-process related information.
`process-plist' and `set-process-plist' to access and replace the
entire property list of a process.
-*** Function `accept-process-output' has a new optional fourth arg
-JUST-THIS-ONE. If non-nil, only output from the specified process
-is handled, suspending output from other processes. If value is an
-integer, also inhibit running timers. This feature is generally not
-recommended, but may be necessary for specific applications, such as
-speech synthesis.
+*** Function `list-processes' now has an optional argument; if non-nil,
+it lists only the processes whose query-on-exit flag is set.
-*** Adaptive read buffering of subprocess output.

obeys file handlers. The file handler is chosen based on
`default-directory'.
+*** Function `signal-process' now accepts a process object or process
+name in addition to a process id to identify the signaled process.
+
+*** Function `accept-process-output' has a new optional fourth arg
+JUST-THIS-ONE. If non-nil, only output from the specified process
+is handled, suspending output from other processes. If value is an
+integer, also inhibit running timers. This feature is generally not
+recommended, but may be necessary for specific applications, such as

+
*** A process filter function gets the output as multibyte string
if the process specifies t for its filter's multibyteness.
Previously, it was converted to multibyte by `string-as-multibyte',
which was not compatible with the behavior of file reading.
-+++
** Enhanced networking support.
*** The new `make-network-process' function makes network connections.
*** The old `open-network-stream' now uses `make-network-process'.
-*** New functions `process-datagram-address', `set-process-datagram-address'.
-
-These functions are used with datagram-based network processes to get
-and set the current address of the remote partner.
-
-*** New function `format-network-address'.
-
-This function reformats the Lisp representation of a network address
-to a printable string. For example, an IP address A.B.C.D and port
-number P is represented as a five element vector [A B C D P], and the
-printable string returned for this vector is "A.B.C.D:P". See the doc
-string for other formatting options.
-
*** `process-contact' has an optional KEY argument.
Depending on this argument, you can get the complete list of network
stopped state. For a client process, no input is received in the
stopped state.
+*** New function `format-network-address'.
+
+This function reformats the Lisp representation of a network address
+to a printable string. For example, an IP address A.B.C.D and port
+number P is represented as a five element vector [A B C D P], and the

+string for other formatting options.
+
*** New function `network-interface-list'.
This function returns a list of network interface names and their
This function returns the network address, hardware address, current
status, and other information about a specific network interface.
+*** New functions `process-datagram-address', `set-process-datagram-address'.
+
+These functions are used with datagram-based network processes to get
+and set the current address of the remote partner.
+
*** Deleting a network process with `delete-process' calls the sentinel.
The status message passed to the sentinel for a deleted network
** Using window objects:
-+++
-*** New function `window-body-height'.
-
-This is like `window-height' but does not count the mode line or the
-header line.
-
-+++
*** You can now make a window as short as one line.
A window that is just one line tall does not display either a mode
cannot display both a mode line and a header line at once; if the
variables call for both, only the mode line actually appears.
-+++
*** The new function `window-inside-edges' returns the edges of the
actual text portion of the window, not including the scroll bar or
divider line, the fringes, the display margins, the header line and
the mode line.
-+++
*** The new functions `window-pixel-edges' and `window-inside-pixel-edges'
return window edges in units of pixels, rather than columns and lines.
-+++
+*** New function `window-body-height'.
+
+This is like `window-height' but does not count the mode line or the
+header line.
+
+*** The new function `adjust-window-trailing-edge' moves the right
+or bottom edge of a window. It does not move other window edges.
+
*** The new macro `with-selected-window' temporarily switches the
selected window without impacting the order of `buffer-list'.
It saves and restores the current buffer, too.
-+++
*** `select-window' takes an optional second argument NORECORD.
This is like `switch-to-buffer'.
-+++
*** `save-selected-window' now saves and restores the selected window
of every frame. This way, it restores everything that can be changed
by calling `select-window'. It also saves and restores the current
buffer.
-+++
*** `set-window-buffer' has an optional argument KEEP-MARGINS.
If non-nil, that says to preserve the window's current margin, fringe,
and scroll-bar settings.
-+++
*** The new function `window-tree' returns a frame's window tree.
-+++
*** The functions `get-lru-window' and `get-largest-window' take an optional
argument `dedicated'. If non-nil, those functions do not ignore
dedicated windows.
-+++
-*** The new function `adjust-window-trailing-edge' moves the right
-or bottom edge of a window. It does not move other window edges.
-
-+++
** Customizable fringe bitmaps
+*** There are new display properties, `left-fringe' and `right-fringe',
+that can be used to show a specific bitmap in the left or right fringe
+bitmap of the display line.
+
+Format is `display (left-fringe BITMAP [FACE])', where BITMAP is a
+symbol identifying a fringe bitmap, either built-in or defined with
+`define-fringe-bitmap', and FACE is an optional face name to be used
+for displaying the bitmap instead of the default `fringe' face.
+When specified, FACE is automatically merged with the `fringe' face.
+
*** New buffer-local variables `fringe-indicator-alist' and
`fringe-cursor-alist' maps between logical (internal) fringe indicator
and cursor symbols and the actual fringe bitmaps to be displayed.
with the `fringe' face, so normally, the face should only specify the
foreground color of the bitmap.
-*** There are new display properties, `left-fringe' and `right-fringe',

-for displaying the bitmap instead of the default `fringe' face.
-When specified, FACE is automatically merged with the `fringe' face.
-
*** New function `fringe-bitmaps-at-pos' returns the current fringe
bitmaps in the display line at a given buffer position.
** Other window fringe features:
-+++
*** Controlling the default left and right fringe widths.
The default left and right fringe widths for all windows of a frame
of the currently defined fringe bitmaps. The width of the built-in
fringe bitmaps is 8 pixels.
-+++
*** Per-window fringe and scrollbar settings
**** Windows can now have their own individual fringe widths and
** Redisplay features:
-+++
*** `sit-for' can now be called with args (SECONDS &optional NODISP).
-+++
*** Iconifying or deiconifying a frame no longer makes sit-for return.
-+++
*** New function `redisplay' causes an immediate redisplay if no input is
available, equivalent to (sit-for 0). The call (redisplay t) forces
an immediate redisplay even if input is pending.
-+++
*** New function `force-window-update' can initiate a full redisplay of
one or all windows. Normally, this is not needed as changes in window
contents are detected automatically. However, certain implicit
changes to mode lines, header lines, or display properties may require
forcing an explicit window update.
-+++
*** (char-displayable-p CHAR) returns non-nil if Emacs ought to be able
to display CHAR. More precisely, if the selected frame's fontset has
a font to display the character set that CHAR belongs to.
Fontsets can specify a font on a per-character basis; when the fontset
does that, this value cannot be accurate.
-+++
*** You can define multiple overlay arrows via the new
variable `overlay-arrow-variable-list'.
If either property is not set, the default `overlay-arrow-string' or
'overlay-arrow-fringe-bitmap' will be used.
-+++
*** New `line-height' and `line-spacing' properties for newline characters
A newline can now have `line-height' and `line-spacing' text or overlay
If the `line-spacing' property is a float or cons, the line spacing
is calculated as specified above for the `line-height' property.
-+++
*** The buffer local `line-spacing' variable can now have a float value,
which is used as a height relative to the default frame line height.
-+++
*** Enhancements to stretch display properties
The display property stretch specification form `(space PROPS)', where
The form `(+ EXPR ...)' adds up the value of the expressions.
The form `(- EXPR ...)' negates or subtracts the value of the expressions.
-+++
*** Normally, the cursor is displayed at the end of any overlay and
text property string that may be present at the current window
position. The cursor can now be placed on any character of such
strings by giving that character a non-nil `cursor' text property.
-+++
*** The display space :width and :align-to text properties are now
supported on text terminals.
-+++
*** Support for displaying image slices
**** New display property (slice X Y WIDTH HEIGHT) can be used with
**** New function `insert-sliced-image' inserts a given image as a
specified number of evenly sized slices (rows x columns).
-+++
*** Images can now have an associated image map via the :map property.
An image map is an alist where each element has the format (AREA ID PLIST).
an event is composed by combining the ID of the hot-spot with the
mouse event, e.g. [area4 mouse-1] if the hot-spot's ID is `area4'.
-+++
*** The function `find-image' now searches in etc/images/ and etc/.
The new variable `image-load-path' is a list of locations in which to
search for image files. The default is to search in etc/images, then
Note that all images formerly located in the lisp directory have been
moved to etc/images.
-+++
*** New function `image-load-path-for-library' returns a suitable
search path for images relative to library. This function is useful in
external packages to save users from having to update
`image-load-path'.
-+++
*** The new variable `max-image-size' defines the maximum size of
images that Emacs will load and display.
-+++
*** The new variable `display-mm-dimensions-alist' can be used to
override incorrect graphical display dimensions returned by functions
`display-mm-height' and `display-mm-width'.
** Mouse pointer features:
-+++ (lispref)
-??? (man)
*** The mouse pointer shape in void text areas (i.e. after the end of a
line or below the last line in the buffer) of the text window is now
controlled by the new variable `void-text-area-pointer'. The default
is to use the `arrow' (non-text) pointer. Other choices are `text'
(or nil), `hand', `vdrag', `hdrag', `modeline', and `hourglass'.
-+++
*** The mouse pointer shape over an image can now be controlled by the
:pointer image property.
-+++
*** The mouse pointer shape over ordinary text or images can now be
controlled/overridden via the `pointer' text property.
** Mouse event enhancements:
-+++
-*** Mouse events for clicks on window fringes now specify `left-fringe'
-or `right-fringe' as the area.
-
-+++
*** All mouse events now include a buffer position regardless of where
you clicked. For mouse clicks in window margins and fringes, this is
a sensible buffer position corresponding to the surrounding text.
-+++
-*** `posn-point' now returns buffer position for non-text area events.
-
-+++
-*** Function `mouse-set-point' now works for events outside text area.
-
-+++
-*** New function `posn-area' returns window area clicked on (nil means
-text area).
+*** Mouse events for clicks on window fringes now specify `left-fringe'
+or `right-fringe' as the area.
-+++
*** Mouse events include actual glyph column and row for all event types
and all areas.
-+++
-*** New function `posn-actual-col-row' returns the actual glyph coordinates
-of the mouse event position.
-
-+++
*** Mouse events can now indicate an image object clicked on.
-+++
*** Mouse events include relative X and Y pixel coordinates relative to
the top left corner of the object (image or character) clicked on.
-+++
*** Mouse events include the pixel width and height of the object
(image or character) clicked on.
-+++
+*** Function `mouse-set-point' now works for events outside text area.
+
+*** `posn-point' now returns buffer position for non-text area events.
+
+*** New function `posn-area' returns window area clicked on (nil means
+text area).
+
+*** New function `posn-actual-col-row' returns the actual glyph coordinates
+of the mouse event position.
+
*** New functions 'posn-object', 'posn-object-x-y', 'posn-object-width-height'.
These return the image or string object of a mouse click, the X and Y
** Text property and overlay changes:
-+++
*** Arguments for `remove-overlays' are now optional, so that you can
remove all overlays in the buffer with just (remove-overlays).
-+++
*** New variable `char-property-alias-alist'.
This variable allows you to create alternative names for text
although it applies to overlays as well. This variable was introduced
to implement the `font-lock-face' property.
-+++
*** New function `get-char-property-and-overlay' accepts the same
arguments as `get-char-property' and returns a cons whose car is the
return value of `get-char-property' called with those arguments and
whose cdr is the overlay in which the property was found, or nil if
it was found as a text property or not found at all.
-+++
*** The new function `remove-list-of-text-properties'.
It is like `remove-text-properties' except that it takes a list of
** Face changes
-+++
*** The variable `facemenu-unlisted-faces' has been removed.
Emacs has a lot more faces than in the past, and nearly all of them
needed to be excluded. The new variable `facemenu-listed-faces' lists
the faces to include in the face menu.
-+++
*** The new face attribute condition `min-colors' can be used to tailor
the face color to the number of colors supported by a display, and
define the foreground and background colors accordingly so that they
is now the preferred method for defining default faces in a way that
makes a good use of the capabilities of the display.
-+++
*** New function `display-supports-face-attributes-p' can be used to test
whether a given set of face attributes is actually displayable.
specification language, which can be used to do this test for faces
defined with `defface'.
----
*** The special treatment of faces whose names are of the form `fg:COLOR'
or `bg:COLOR' has been removed. Lisp programs should use the
`defface' facility for defining faces with specific colors, or use
the feature of specifying the face attributes :foreground and :background
directly in the `face' property instead of using a named face.
-+++
*** The first face specification element in a defface can specify
`default' instead of frame classification. Then its attributes act as
defaults that apply to all the subsequent cases (and can be overridden
by them).
-+++
-*** The variable `face-font-rescale-alist' specifies how much larger
-(or smaller) font we should use. For instance, if the value is
-'((SOME-FONTNAME-PATTERN . 1.3)) and a face requests a font of 10
-point, we actually use a font of 13 point if the font matches
-SOME-FONTNAME-PATTERN.
-
----
*** The function `face-differs-from-default-p' now truly checks
whether the given face displays differently from the default face or
not (previously it did only a very cursory check).
-+++
*** `face-attribute', `face-foreground', `face-background', `face-stipple'.
These now accept a new optional argument, INHERIT, which controls how
face inheritance is used when determining the value of a face
attribute.
-+++
*** New functions `face-attribute-relative-p' and `merge-face-attribute'
help with handling relative face attributes.
-+++
*** The priority of faces in an :inherit attribute face list is reversed.
If a face contains an :inherit attribute with a list of faces, earlier
so that :inherit face lists operate identically to face lists in text
`face' properties.
----
+*** The variable `face-font-rescale-alist' specifies how much larger
+(or smaller) font we should use. For instance, if the value is
+'((SOME-FONTNAME-PATTERN . 1.3)) and a face requests a font of 10
+point, we actually use a font of 13 point if the font matches
+SOME-FONTNAME-PATTERN.
+
*** On terminals, faces with the :inverse-video attribute are displayed
with swapped foreground and background colors even when one of them is
not specified. In previous releases of Emacs, if either foreground
or background color was unspecified, colors were not swapped. This
was inconsistent with the face behavior under X.
----
*** `set-fontset-font', `fontset-info', `fontset-font' now operate on
the default fontset if the argument NAME is nil..
** Font-Lock changes:
-+++
*** New special text property `font-lock-face'.
This property acts like the `face' property, but it is controlled by
property. Instead, it is implemented inside font-core.el, using the
new variable `char-property-alias-alist'.
-+++
*** font-lock can manage arbitrary text-properties beside `face'.
**** the FACENAME returned in `font-lock-keywords' can be a list of the
**** `font-lock-extra-managed-props' can be set to make sure those
extra properties are automatically cleaned up by font-lock.
----
*** jit-lock obeys a new text-property `jit-lock-defer-multiline'.
If a piece of text with that property gets contextually refontified
** Major mode mechanism changes:
-+++
-*** If new variable `auto-mode-case-fold' is set to a non-nil value,
-Emacs will perform a second case-insensitive search through
-`auto-mode-alist' if the first case-sensitive search fails.
-This means that a file FILE.TXT is opened in text-mode, and a file PROG.PY
-is opened in python-mode. Note however, that independent of this
-setting, *.C files are usually recognized as C++ files.
-It also has no effect on systems with case-insensitive file names.
-
-+++
*** New variable `magic-mode-alist' determines major mode for a file by
looking at the file contents. It takes precedence over `auto-mode-alist'.
-+++
-*** An interpreter magic line (if present) takes precedence over the
-file name when setting the major mode.
+*** New variable `magic-fallback-mode-alist' determines major mode for a file by
+looking at the file contents. It is handled after `auto-mode-alist',
+only if `auto-mode-alist' (and `magic-mode-alist') says nothing about the file.
-+++
*** XML or SGML major mode is selected when file starts with an `<?xml'
or `<!DOCTYPE' declaration.
-+++
-*** Use the new function `run-mode-hooks' to run the major mode's mode hook.
+*** An interpreter magic line (if present) takes precedence over the
+file name when setting the major mode.
+
+*** If new variable `auto-mode-case-fold' is set to a non-nil value,
+Emacs will perform a second case-insensitive search through
+`auto-mode-alist' if the first case-sensitive search fails. This
+means that a file FILE.TXT is opened in text-mode, and a file
+PROG.HTML is opened in html-mode. Note however, that independent of
+this setting, *.C files are usually recognized as C++ files. It also
+has no effect on systems with case-insensitive file names.
-+++
*** All major mode functions should now run the new normal hook
`after-change-major-mode-hook', at their very end, after the mode
hooks. `run-mode-hooks' does this automatically.
----
-*** If a major mode function has a non-nil `no-clone-indirect'
-property, `clone-indirect-buffer' signals an error if you use
-it in that buffer.
-
-+++
*** Major modes can define `eldoc-documentation-function'
locally to provide Eldoc functionality by some method appropriate to
the language.
-+++
-*** `define-derived-mode' by default creates a new empty abbrev table.
-It does not copy abbrevs from the parent mode's abbrev table.
+*** Use the new function `run-mode-hooks' to run the major mode's mode hook.
-+++
*** The new function `run-mode-hooks' and the new macro `delay-mode-hooks'
are used by `define-derived-mode' to make sure the mode hook for the
parent mode is run at the end of the child mode.
+*** `define-derived-mode' by default creates a new empty abbrev table.
+It does not copy abbrevs from the parent mode's abbrev table.
+
+*** If a major mode function has a non-nil `no-clone-indirect'
+property, `clone-indirect-buffer' signals an error if you use
+it in that buffer.
+
** Minor mode changes:
-+++
*** `define-minor-mode' now accepts arbitrary additional keyword arguments
and simply passes them to `defcustom', if applicable.
-+++
-*** `minor-mode-list' now holds a list of minor mode commands.
-
-+++
-*** `define-global-minor-mode'.
+*** `define-globalized-minor-mode'.
This is a new name for what was formerly called
`easy-mmode-define-global-mode'. The old name remains as an alias.
+*** `minor-mode-list' now holds a list of minor mode commands.
+
** Command loop changes:
-+++
*** The new function `called-interactively-p' does what many people
have mistakenly believed `interactive-p' to do: it returns t if the
calling function was called through `call-interactively'.
Only use this when you cannot solve the problem by adding a new
INTERACTIVE argument to the command.
-+++
*** The function `commandp' takes an additional optional argument.
If it is non-nil, then `commandp' checks for a function that could be
called with `call-interactively', and does not return t for keyboard
macros.
-+++
*** When a command returns, the command loop moves point out from
within invisible text, in the same way it moves out from within text
covered by an image or composition property.
(including `goto-char', ...) whereas this new code is only run after
`post-command-hook' and thus does not care about intermediate states.
-+++
*** If a command sets `transient-mark-mode' to `only', that
enables Transient Mark mode for the following command only.
During that following command, the value of `transient-mark-mode'
is `identity'. If it is still `identity' at the end of the command,
the next return to the command loop changes to nil.
-+++
*** Both the variable and the function `disabled-command-hook' have
been renamed to `disabled-command-function'. The variable
`disabled-command-hook' has been kept as an obsolete alias.
-+++
*** `emacsserver' now runs `pre-command-hook' and `post-command-hook'
when it receives a request from emacsclient.
-+++
*** `current-idle-time' reports how long Emacs has been idle.
** Lisp file loading changes:
-+++
*** `load-history' can now have elements of the form (t . FUNNAME),
which means FUNNAME was previously defined as an autoload (before the
current file redefined it).
-+++
*** `load-history' now records (defun . FUNNAME) when a function is
defined. For a variable, it records just the variable name.
-+++
*** The function `symbol-file' can now search specifically for function,
variable or face definitions.
-+++
*** `provide' and `featurep' now accept an optional second argument
to test/provide subfeatures. Also `provide' now checks `after-load-alist'
and runs any code associated with the provided feature.
----
*** The variable `recursive-load-depth-limit' has been deleted.
Emacs now signals an error if the same file is loaded with more
than 3 levels of nesting.
-+++
** Byte compiler changes:
*** The byte compiler now displays the actual line and character
*** The local variable `no-byte-compile' in Lisp files is now obeyed.
----
*** When a Lisp file uses CL functions at run-time, compiling the file
now issues warnings about these calls, unless the file performs
(require 'cl) when loaded.
** Frame operations:
-+++
*** New functions `frame-current-scroll-bars' and `window-current-scroll-bars'.
These functions return the current locations of the vertical and
horizontal scroll bars in a frame or window.
-+++
*** The new function `modify-all-frames-parameters' modifies parameters
for all (existing and future) frames.
-+++
*** The new frame parameter `tty-color-mode' specifies the mode to use
for color support on character terminal frames. Its value can be a
number of colors to support, or a symbol. See the Emacs Lisp
Reference manual for more detailed documentation.
-+++
*** When using non-toolkit scroll bars with the default width,
the `scroll-bar-width' frame parameter value is nil.
+** Mode line changes:
+
+*** New function `format-mode-line'.
+
+This returns the mode line or header line of the selected (or a
+specified) window as a string with or without text properties.
+
+*** The new mode-line construct `(:propertize ELT PROPS...)' can be
+used to add text properties to mode-line elements.
+
+*** The new `%i' and `%I' constructs for `mode-line-format' can be used
+to display the size of the accessible part of the buffer on the mode
+line.
+
+*** Mouse-face on mode-line (and header-line) is now supported.
+
+** Menu manipulation changes:
+
+*** To manipulate the File menu using easy-menu, you must specify the
+proper name "file". In previous Emacs versions, you had to specify
+"files", even though the menu item itself was changed to say "File"
+several versions ago.
+
+*** The dummy function keys made by easy-menu are now always lower case.
+If you specify the menu item name "Ada", for instance, it uses `ada'
+as the "key" bound by that key binding.
+
+This is relevant only if Lisp code looks for the bindings that were
+made with easy-menu.
+
+*** `easy-menu-define' now allows you to use nil for the symbol name
+if you don't need to give the menu a name. If you install the menu
+into other keymaps right away (MAPS is non-nil), it usually doesn't
+need to have a name.
+
** Mule changes:
-+++
*** Already true in Emacs 21.1, but not emphasized clearly enough:
Multibyte buffers can now faithfully record all 256 character codes
3. For binary files where format conversion would be pointless and
wasteful.
----
-*** `set-buffer-file-coding-system' now takes an additional argument,
-NOMODIFY. If it is non-nil, it means don't mark the buffer modified.
-
-+++
*** The new variable `auto-coding-functions' lets you specify functions
to examine a file being visited and deduce the proper coding system
for it. (If the coding system is detected incorrectly for a specific
file, you can put a `coding:' tags to override it.)
----
+*** The new variable `ascii-case-table' stores the case table for the
+ascii character set. Language environments (such as Turkish) may
+alter the case correspondences of ASCII characters. This variable
+saves the original ASCII case table before any such changes.
+
*** The new function `merge-coding-systems' fills in unspecified aspects
of one coding system from another coding system.
----
*** New coding system property `mime-text-unsuitable' indicates that
the coding system's `mime-charset' is not suitable for MIME text
parts, e.g. utf-16.
-+++
*** New function `decode-coding-inserted-region' decodes a region as if
it is read from a file without decoding.
----
*** New CCL functions `lookup-character' and `lookup-integer' access
hash tables defined by the Lisp function `define-translation-hash-table'.
----
*** New function `quail-find-key' returns a list of keys to type in the
current input method to input a character.
-** Mode line changes:
-
-+++
-*** New function `format-mode-line'.
-
-This returns the mode line or header line of the selected (or a
-specified) window as a string with or without text properties.
-
-+++
-*** The new mode-line construct `(:propertize ELT PROPS...)' can be
-used to add text properties to mode-line elements.
-
-+++
-*** The new `%i' and `%I' constructs for `mode-line-format' can be used
-to display the size of the accessible part of the buffer on the mode
-line.
-
-+++
-*** Mouse-face on mode-line (and header-line) is now supported.
-
-** Menu manipulation changes:
-
----
-*** To manipulate the File menu using easy-menu, you must specify the
-proper name "file". In previous Emacs versions, you had to specify
-"files", even though the menu item itself was changed to say "File"
-several versions ago.
-
----
-*** The dummy function keys made by easy-menu are now always lower case.
-If you specify the menu item name "Ada", for instance, it uses `ada'
-as the "key" bound by that key binding.
-
-This is relevant only if Lisp code looks for the bindings that were
-made with easy-menu.
-
----
-*** `easy-menu-define' now allows you to use nil for the symbol name
-if you don't need to give the menu a name. If you install the menu
-into other keymaps right away (MAPS is non-nil), it usually doesn't
-need to have a name.
+*** `set-buffer-file-coding-system' now takes an additional argument,
+NOMODIFY. If it is non-nil, it means don't mark the buffer modified.
** Operating system access:
-+++
*** The new primitive `get-internal-run-time' returns the processor
run time used by Emacs since start-up.
-+++
*** Functions `user-uid' and `user-real-uid' now return floats if the
user UID doesn't fit in a Lisp integer. Function `user-full-name'
accepts a float as UID parameter.
-+++
*** New function `locale-info' accesses locale information.
----
*** On MS Windows, locale-coding-system is used to interact with the OS.
The Windows specific variable w32-system-coding-system, which was
formerly used for that purpose is now an alias for locale-coding-system.
----
*** New function `redirect-debugging-output' can be used to redirect
debugging output on the stderr file handle to a file.
+** GC changes:
+
+*** New variable `gc-cons-percentage' automatically grows the GC cons threshold
+as the heap size increases.
+
+*** New variables `gc-elapsed' and `gcs-done' provide extra information
+on garbage collection.
+
+*** The normal hook `post-gc-hook' is run at the end of garbage collection.
+
+The hook is run with GC inhibited, so use it with care.
+
** Miscellaneous:
-+++
*** A number of hooks have been renamed to better follow the conventions:
`find-file-hooks' to `find-file-hook',
In each case the old name remains as an alias for the moment.
-+++
*** Variable `local-write-file-hooks' is marked obsolete.
Use the LOCAL arg of `add-hook'.
----
*** New function `x-send-client-message' sends a client message when
running under X.
-
-** GC changes:
-
-+++
-*** New variable `gc-cons-percentage' automatically grows the GC cons threshold
-as the heap size increases.
-
-+++
-*** New variables `gc-elapsed' and `gcs-done' provide extra information
-on garbage collection.
-
-+++
-*** The normal hook `post-gc-hook' is run at the end of garbage collection.
-
-The hook is run with GC inhibited, so use it with care.
\f
* New Packages for Lisp Programming in Emacs 22.1
-+++
** The new library button.el implements simple and fast `clickable
buttons' in Emacs buffers. Buttons are much lighter-weight than the
`widgets' implemented by widget.el, and can be used by lisp code that
doesn't require the full power of widgets. Emacs uses buttons for
such things as help and apropos buffers.
----
** The new library tree-widget.el provides a widget to display a set
of hierarchical data as an outline. For example, the tree-widget is
well suited to display a hierarchy of directories and files.
-+++
** The new library bindat.el provides functions to unpack and pack
binary data structures, such as network packets, to and from Lisp
data structures.
----
** master-mode.el implements a minor mode for scrolling a slave
buffer without leaving your current buffer, the master buffer.
(function (lambda ()
(master-set-slave sql-buffer))))
-+++
** The new library benchmark.el does timing measurements on Lisp code.
This includes measuring garbage collection time.
-+++
** The new library testcover.el does test coverage checking.
