select the right one.
+---
** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk'
when you run configure. This requires Gtk+ 2.0 or newer. This port
provides a way to display multilingual text in menus (with some caveats).

** Emacs can now be built without sound support.
+---
** The `emacsserver' program has been removed, replaced with elisp code.

-* Changes in Emacs 21.4
+* Changes in Emacs 22.1
+
+** Languange 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 may result in using the different coding systems as
+default in some locale (e.g. vi_VN).
+
++++
+** 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
+the existing file's name. (This is the same convention that shell
+commands cp, mv, and ln follow.) Thus, M-x copy-file RET ~/foo RET
+/tmp RET copies ~/foo to /tmp/foo.
+
++++
+** M-o now is the prefix key for setting text properties;
+M-o M-o requests refontification.
+
++++
+** M-g is now a prefix key. M-g g and M-g M-g run goto-line.
+
++++
+** font-lock-lines-before specifies a number of lines before the
+current line that should be refontified when you change the buffer.
+The default value is 1.
+
++++
+** C-u M-x goto-line now 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.
+
+---
+** Emacs now responds to mouse-clicks on the mode-line, header-line and
+display margin, when run in an xterm.
+
++++
+** M-SPC (just-one-space) when given a numeric argument N
+converts whitespace around point to N spaces.
+
++++
+** Control characters and escape glyphs are now shown in the new
+escape-glyph face.
+
++++
+** Non-breaking space and hyphens are now prefixed with an escape
+character, unless the new user variable `show-nonbreak-escape' is set
+to 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.
+
+---
+** display-battery has been replaced by display-battery-mode.
-** calculator.el now has radix grouping mode. In this mode a
-separator character is used between every few digits, making it
-easier to indicate byte boundries etc. See the documentation of
-the `calculator-radix-grouping-mode' custom variable.
+---
+** calculator.el now has radix grouping mode, which is available when
+`calculator-output-radix' is non-nil. In this mode a separator
+character is used every few digits, making it easier to see byte
+boundries etc. For more info, see the documentation of the variable
+`calculator-radix-grouping-mode'.
++++
** 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. With release 21.4, the behaviour of a Mouse-1 click
-has been changed to match this context-sentitive dual behaviour.

Depending on the current mode, a Mouse-2 click in Emacs may do much
-more than just follow a link, so the new Mouse-1 behaviour is only
+more than just follow a link, so the new Mouse-1 behavior is only

Dragging the Mouse-1 inside a link still performs the original
drag-mouse-1 action, typically copy the text.
-You can customize the new Mouse-1 behaviour via the new user option
-`mouse-1-click-follows-link'.
+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'.
+
++++
+** require-final-newline now has two new possible values:
+
+`visit' means add a newline (as an undoable change) if it's needed
+when visiting the file.
+
+`visit-save' means add a newline (as an undoable change) if it's
+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
+sets require-final-newline based on mode-require-final-newline.
+So you can customize mode-require-final-newline to control what these
+modes do.
+++
** When the undo information of the current command gets really large
-(beyond the value of `undo-outer-limit'), Emacs asks you whether to
-discard it or keep it.
+(beyond the value of `undo-outer-limit'), Emacs discards it and warns
+you about it.
++++
** line-move-ignore-invisible now defaults to t.
++++
** In Outline mode, hide-body no longer hides lines at the top
of the file that precede the first header line.
** `apply-macro-to-region-lines' now operates on all lines that begin
in the region, rather than on all complete lines in the region.
+---
** global-whitespace-mode is a new alias for whitespace-global-mode.
+++
will start up Emacs on an initial frame of 100x20 with red background,
irrespective of geometry or background setting on the Windows registry.
+---
+** The terminal emulation code in term.el has been improved, it can
+run most curses applications now.
+
** 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.
+---
** New input method chinese-sisheng for inputting Chinese Pinyin
characters.
++++
** New command quail-show-key shows what key (or key sequence) to type
in the current input method to input a character at point.
++++
** Convenient commands to switch buffers in a cyclic order are C-x <left>
(prev-buffer) and C-x <right> (next-buffer).
+---
** 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.
+---
** 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
`kill-region' if read-only are involved: it copies the text to the
kill-ring, but does not delete 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.
++++
** Telnet now prompts you for a port number with C-u M-x telnet.
+++
the menu-bar, the tool-bar, the scroll-bars, tool tips, the blinking
cursor, and the fancy startup screen.
++++
+** New command line option -nbc or --no-blinking-cursor disables
+the blinking cursor on graphical terminals.
+
++++
** 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).
+---
** 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'.
++++
** 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
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
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.
++++
** 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.
+---
** M-x compile has become more robust and reliable
Quite a few more kinds of messages are recognized. Messages that are
compilation processes without affecting the environment that all
subprocesses inherit.
++++
** Grep has been decoupled from compilation mode setup.
+---
*** There's a new separate package grep.el.
+---
*** M-x grep has been adapted to new compile
Hits are fontified in green, and hits in binary files in orange. Grep buffers
can be saved and automatically revisited with the new Grep mode.
+---
*** Grep commands now have their 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.
+
+---
*** The new variables `grep-window-height', `grep-auto-highlight', and
`grep-scroll-output' can be used to override the corresponding
compilation mode settings for grep commands.
++++
*** New option `grep-highlight-matches' highlightes 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.
++++
** 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.
++++
** M-x diff uses diff-mode instead of compilation-mode.
++++
** M-x compare-windows now can automatically skip non-matching text to
resync points in both windows.
+---
** 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
** 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.
+++
** Desktop package
++++
*** Desktop saving is now a minor mode, desktop-save-mode. 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 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. Determins whether the desktop should be saved when it is
killed.
- - desktop-file-name-format.
+ - 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.
- - desktop-globals-to-clear.
- - desktop-clear-preserve-buffers-regexp.
+ - 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 command line option --no-desktop
+---
*** New hooks:
- desktop-after-read-hook run after a desktop is loaded.
- desktop-no-desktop-file-hook run when no desktop file is found.
and `save-place-skip-check-regexp' allow further fine-tuning of this
feature.

** The buffer boundaries (i.e. first and last line in the buffer) may
arrow bitmaps in right fringe. To show just the angle bitmaps in the
left fringe, but no arrow bitmaps, use ((top . left) (bottom . left)).
++++
** 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
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.
+---
** New commands `scan-buf-next-region' and `scan-buf-previous-region'
move to the start of the next (previous, respectively) region with
non-nil help-echo property and display any help found there in the
enclosed in single quotes and preceded by `info anchor' or `Info
anchor' (in addition to earlier `info node' and `Info node').
++++
** The max size of buffers and integers has been doubled.
On 32bit machines, it is now 256M (i.e. 268435455).
now reads arguments for the function interactively if it is
an interactively callable function.
-
+---
** sql changes.
*** The variable `sql-product' controls the highlightng of different
appropriate sql-interactive-mode wrapper for the current setting of
`sql-product'.
+---
** M-x view-file and commands that use it now avoid interfering
with special modes such as Tar mode.
** Enhancements to apropos commands:
++++
*** 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
since there are situations where one or the other will shut down
the operating system or your X server.
+---
** New minor mode, Visible mode, toggles invisibility in the current buffer.
When enabled, it makes all invisible text visible. When disabled, it
restores the previous value of `buffer-invisibility-spec'.
+---
** New command `kill-whole-line' kills an entire line at once.
By default, it is bound to C-S-<backspace>.
+---
** New commands to operate on pairs of open and close characters:
`insert-pair', `delete-pair', `raise-sexp'.
++++
** A prefix argument of C-M-q in Emacs Lisp mode pretty-printifies the
list starting after point.
** Dired mode:
+---
*** 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.
special treatment in `dired-do-shell-command'.
+++
-*** Dired's v command now runs external viewers to view certain
-types of files. The variable `dired-view-command-alist' controls
-what external viewers to use and when.
-
*** In Dired, the w command now copies the current line's file name
into the kill ring. With a zero prefix arg, copies absolute file names.
+++
** 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-mark-omitted, bound to M-O,
marks omitted files. The variable dired-omit-files-p is obsoleted, use the
** Info mode:
++++
*** A numeric prefix argument of `info' selects an Info buffer
-with the number appended to the *info* buffer name.
+with the number appended to the *info* buffer name (e.g. "*info*<2>").
-*** Regexp isearch (C-M-s and C-M-r) can search through multiple nodes.
-Failed isearch wraps to the top/final node.
+---
+*** isearch in Info uses Info-search and searches through multiple nodes.
+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
+aroung 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.
*** 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.
+*** 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').
+
*** New command `Info-history' (bound to L) displays a menu of visited nodes.
*** New command `Info-toc' (bound to T) creates a node with table of contents
---
*** Info-index offers completion.
+---
** Support for the SQLite interpreter has been added to sql.el by calling
'sql-sqlite'.
*** The new command bibtex-copy-summary-as-kill pushes summary
of BibTeX entry to kill ring (bound to C-c C-t).
++++
** When display margins are present in a window, the fringes are now
displayed between the margins and the buffer's text area, rather than
at the edges of the window.
++++
** A window may 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.
++++
** 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.
----
++++
** 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.
++++
** Under X, mouse-wheel-mode is turned on by default.
** The X resource useXIM can be used to turn off use of XIM, which may
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.

** `undo-only' does an undo which does not redo any previous undo.
+---
** `uniquify-strip-common-suffix' tells uniquify to prefer
`file|dir1' and `file|dir2' to `file|dir1/subdir' and `file|dir2/subdir'.
++++
** If the user visits a file larger than `large-file-warning-threshold',
Emacs prompts her for confirmation.
+---
** A UTF-7 coding system is available in the library `utf-7'.
+---
** GUD mode has its own tool bar for controlling execution of the inferior
and other common debugger commands.
+---
** recentf changes.
The recent file list is now automatically cleanup when recentf mode is
enabled. The new option `recentf-auto-cleanup' controls when to do
automatic cleanup.
+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-handler', you can
specify a function that transforms filenames handled by recentf. For
example, if set to `file-truename', the same file will not be in the
recent list with different symbolic links.
-To follow naming convention, `recentf-keep-non-readable-files-flag'
-and `recentf-menu-append-commands-flag' respectively replace the
-misnamed options `recentf-keep-non-readable-files-p' and
-`recentf-menu-append-commands-p'. The old names remain available as
-aliases, but have been marked obsolete.

** The default for the paper size (variable ps-paper-type) is taken
from the locale.
++++
** Init file changes
You can now put the init files .emacs and .emacs_SHELL under
~/.emacs.d or directly under ~. Emacs will find them in either place.

** New language environments: French, Ukrainian, Tajik,
Bulgarian, Belarusian, Ukrainian, UTF-8, Windows-1255, Welsh, Latin-6,
Latin-7, Lithuanian, Latvian, Swedish, Slovenian, Croatian, Georgian,
Italian, Russian, Malayalam, Tamil, Russian, Chinese-EUC-TW. (Set up
automatically according to the locale.)

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.
++++
** 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

** 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
`auto-hscroll-mode'. The old name is still available as an alias.
** TeX modes:

+++
*** 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
