+When you add a new item, please add it without either +++ or ---
+so we will look at it
+
+\f
+* Installation Changes in Emacs 21.3
+
+** Emacs now supports new configure options `--program-prefix',
+`--program-suffix' and `--program-transform-name' that affect the names of
+installed programs.
+
+---
+** Leim is now part of the Emacs distribution.
+You no longer need to download a separate tarball in order to build
+Emacs with Leim.
+
+** Support for FreeBSD/Alpha has been added.
+
+\f
+* Changes in Emacs 21.3
+
++++
+** 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 works only on GNU and Unix systems, and
+not with every window manager.)
+
+** Info-index finally offers completion.
+
+** Controlling the left and right fringe widths.
+
+The left and right fringe widths can now be controlled by setting the
+`left-fringe' and `right-fringe' frame parameters to an integer value
+specifying the width in pixels. Setting the width to 0 effectively
+removes the corresponding fringe.
+
+The actual fringe widths may deviate from the specified widths, since
+the combined fringe widths must match an integral number of columns.
+The extra width is distributed evenly between the left and right fringe.
+For force a specific fringe width, specify the width as a negative
+integer (if both widths are negative, only the left fringe gets the
+specified width).
+
+Setting the width to nil (the default), restores the default fringe
+width which is the minimum number of pixels necessary to display any
+of the currently defined fringe bitmaps. The width of the built-in
+fringe bitmaps is 8 pixels.
+
+** Changes in C-h bindings:
+
+C-h e displays the *Messages* buffer.
+
+C-h followed by a control character is used for displaying files
+ that do not change:
+
+C-h C-f displays the FAQ.
+C-h C-e displays the PROBLEMS 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.
+
+** 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'.
+
+** 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).
+
+** 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 line C-e and C-p.
+
+** 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
+doublequotes make no difference in the shell, but they prevent
+special treatment in `dired-do-shell-command'.
+
+** 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.
+
+** 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
+idle time in seconds to wait before starting fontification. For
+example, if you set `jit-lock-defer-time' to 0.25, fontification will
+only happen after 0.25s of idle time.
+
+** If you hit M-C-SPC (mark-sexp) repeatedly, the marked region
+will now be extended each time, so you can mark the next two sexps with
+M-C-SPC M-C-SPC, for example.
+
+** 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.
+
+** 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.
+
++++
+** 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.
+
+** In Dired, the w command now copies the current line's file name
+into the kill ring.
+
+** 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
+directory listing into a buffer.
+
+** mouse-wheels can now scroll a specific fraction of the window
+(rather than a fixed number of lines) and the scrolling is `progressive'.
+
+** The keyboard-coding-system is now automatically set based on
+your current locale settings. If it turns out that your terminal
+does not support the encoding implied by your locale (for example,
+it inserts non-ASCII chars if you hit M-i), you will need to add
+
+ (set-keyboard-coding-system nil)
+
+to your .emacs to revert to the old behavior.
+
+** 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.
+
++++
+** 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'.
+
+** 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 default values of `tooltip-delay' and `tooltip-hide-delay'
+were changed.
+
+** On terminals whose erase-char is ^H (Backspace), Emacs
+now uses normal-erase-is-backspace-mode.
+
+** Etags changes.
+
+*** In Prolog, etags creates tags for rules in addition to predicates.
+
+*** In Perl, packages are tags. Subroutine tags are named from their
+package. You can jump to sub tags as you did before, by the sub name, or
+additionally by looking for package::sub.
+
+*** New language PHP: tags are functions, classes and defines. If
+the --members option is specified to etags, tags are vars also.
+
++++
+** The command line option --no-windows has been changed to
+--no-window-system. The old one still works, but is deprecated.
+
+** `buffer-menu' and `list-buffers' now list buffers whose names begin
+with a space, if they visit files.
+
+** You can now customize fill-nobreak-predicate to control where
+filling can break lines. We provide two sample predicates,
+fill-single-word-nobreak-p and fill-french-nobreak-p.
+
+** New user option `add-log-always-start-new-record'.
+When this option is enabled, M-x add-change-log-entry will always
+start a new record regardless of when the last record is.
+
+** New user option `sgml-xml'.
+When this option is enabled, SGML tags are inserted in XML style,
+i.e., there is always a closing tag.
+When not customized, it becomes buffer-local when it can be inferred
+from the file name or buffer contents.
+
+** New user option `isearch-resume-enabled'.
+This option can be disabled, to avoid the normal behaviour of isearch
+which puts calls to `isearch-resume' in the command history.
+
+** When the *scratch* buffer is recreated, its mode is set from
+initial-major-mode, which normally is lisp-interaction-mode,
+instead of using default-major-mode.
+
+** Byte compiler warning and error messages have been brought more
+in line with the output of other GNU tools.
+
+** Lisp-mode now uses font-lock-doc-face for the docstrings.
+
+** perl-mode has a new variable `perl-indent-continued-arguments'.
+
+** `special-display-buffer-names' and `special-display-regexps' now
+understand two new boolean pseudo-frame-parameters `same-frame' and
+`same-window'.
+
+** When pure storage overflows while dumping, Emacs now prints how
+much pure storage it will approximately need.
+
+** M-x setenv now expands environment variables of the form `$foo' and
+`${foo}' in the specified new value of the environment variable. To
+include a `$' in the value, use `$$'.
+
++++
+** File-name completion can now ignore directories.
+If an element of the list in `completion-ignored-extensions' ends in a
+slash `/', it indicates a subdirectory that should be ignored when
+completing file names. Elements of `completion-ignored-extensions'
+which do not end in a slash are never considered when a completion
+candidate is a directory.
+
+** 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.
+
+** Rmail now displays 5-digit message ids in its summary buffer.
+
+** When using M-x revert-buffer in a compilation buffer to rerun a
+compilation, it is now made sure that the compilation buffer is reused
+in case it has been renamed.
+
+** 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.
+
+** Tooltips now work on MS Windows.
+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.
+

+** A French translation of the `Emacs Survival Guide' is available.
+
+---
+** A French translation of the Emacs Tutorial is available.
+
+** New modes and packages
+
++++
+*** Calc is now part of the Emacs distribution.
+
+Calc is an advanced desk calculator and mathematical tool written in
+Emacs Lisp. Its documentation is in a separate manual; within Emacs,
+type "C-h i m calc RET" to read that manual. A reference card is
+available in `etc/calccard.tex' and `etc/calccard.ps'.
+
++++
+*** The Emacs Lisp Reference Manual is now part of the distribution.
+
+The ELisp 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
+accessible (Help->More Manuals->Emacs Lisp Reference).
+
+*** The Introduction to Programming in Emacs Lisp manual is now part of
+the distribution.
+
+This manual is now part of the standard distribution and is installed,
+together with the Emacs User Manual, into the Info directory. A menu
+item was added to the menu bar that makes it easy accessible
+(Help->More Manuals->Introduction to Emacs Lisp).
+
+*** The ruler-mode.el library provides a minor mode for displaying an
+"active" ruler in the header line. You can use the mouse to visually
+change the `fill-column', `window-margins' and `tab-stop-list'
+settings.
+
+*** The reveal.el package provides the minor modes `reveal-mode' and
+`global-reveal-mode' which will make text visible on the fly as you
+move your cursor into hidden region of the buffer.
+It should work with any package that uses overlays to hide parts
+of a buffer, such as outline-minor-mode, hs-minor-mode, hide-ifdef-mode, ...
+
+*** master-mode.el implements a minor mode for scrolling a slave
+buffer without leaving your current buffer, the master buffer.
+
+It can be used by sql.el, for example: the SQL buffer is the master
+and its SQLi buffer is the slave. This allows you to scroll the SQLi
+buffer containing the output from the SQL buffer containing the
+commands.
+
+This is how to use sql.el and master.el together: the variable
+sql-buffer contains the slave buffer. It is a local variable in the
+SQL buffer.
+
+(add-hook 'sql-mode-hook
+ (function (lambda ()
+ (master-mode t)
+ (master-set-slave sql-buffer))))
+(add-hook 'sql-set-sqli-hook
+ (function (lambda ()
+ (master-set-slave sql-buffer))))
+
+\f
+* Lisp Changes in Emacs 21.3
+
+** Already true in Emacs 21.1, but not emphasized clearly enough:
+
+Multibyte buffers can now faithfully record all 256 character codes
+from 0 to 255. As a result, most of the past reasons to use unibyte
+buffers no longer exist. We only know of three reasons to use them
+now:
+
+1. If you prefer to use unibyte text all of the time.
+
+2. For reading files into temporary buffers, when you want to avoid
+the time it takes to convert the format.
+
+3. For binary files where format conversion would be pointless and
+wasteful.
+
+** If text has a `keymap' property, that keymap takes precedence
+over minor mode keymaps.
+
+** A hex escape in a string forces the string to be multibyte.
+An octal escape makes it unibyte.
+
+** The position after an invisible, intangible character
+is considered an unacceptable value for point;
+intangibility processing effectively treats the following character
+as part of the intangible region even if it is not itself intangible.
+
+Thus, point can go before an invisible, intangible region, but not
+after it. This prevents C-f and C-b from appearing to stand still on
+the screen.
+
++++
+** define-abbrev now accepts an optional argument SYSTEM-FLAG. 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.
+
+** Support for Mocklisp has been removed.
+
+** The function insert-string is now obsolete.
+
+** The precedence of file-name-handlers has been changed.
+Instead of blindly choosing the first handler that matches,
+find-file-name-handler now gives precedence to a file-name handler
+that matches near the end of the file name. More specifically, the
+handler whose (match-beginning 0) is the largest is chosen.
+In case of ties, the old "first matched" rule applies.
+
+** Dense keymaps now handle inheritance correctly.
+Previously a dense keymap would hide all of the simple-char key
+bindings of the parent keymap.
+
+** jit-lock obeys a new text-property `jit-lock-defer-multiline'.
+If a piece of text with that property gets contextually refontified
+(see jit-lock-defer-contextually), then all of that text will
+be refontified. This is useful when the syntax of a textual element
+depends on text several lines further down (and when font-lock-multiline
+is not appropriate to solve that problem). For example in Perl:
+
+ s{
+ foo
+ }{
+ bar
+ }e
+
+Adding/removing the last `e' changes the `bar' from being a piece of
+text to being a piece of code, so you'd put a jit-lock-defer-multiline
+property over the second half of the command to force (deferred)
+refontification of `bar' whenever the `e' is added/removed.
+
+** describe-vector now takes a second argument `describer' which is
+called to print the entries' values. It defaults to `princ'.
+
+** defcustom and other custom declarations now use a default group
+(the last group defined in the same file) when no :group was given.
+
+** emacsserver now runs pre-command-hook and post-command-hook when
+it receives a request from emacsclient.
+
+** 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.
+
+** 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.
+
+** 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.
+
+** If you set `query-replace-skip-read-only' non-nil,
+`query-replace' and related functions simply ignore
+a match if part of it has a read-only property.
+
+** In `replace-match', the replacement text no longer inherits
+properties from surrounding text.
+
+** New function `buffer-local-value'.
+
+- Function: buffer-local-value variable buffer
+
+This function 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 default value of `paragraph-start' and `indent-line-function' has
+been changed to reflect the one used in Text mode rather than the one
+used in Indented Text mode.
+
+** 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.
+
+** font-lock can manage arbitrary text-properties beside `face'.
+*** the FACENAME returned in font-lock-keywords can be a list
+of the form (face FACE PROP1 VAL1 PROP@ VAL2 ...) so you can set
+other properties than `face'.
+*** font-lock-extra-managed-props can be set to make sure those extra
+properties are automatically cleaned up by font-lock.
+
+** 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.
+
+** `provide' and `featurep' now accept an optional second argument
+to test/provide subfeatures. Also `provide' now checks `after-load-alist'
+and run any code associated with the provided feature.
+
+** The variable `compilation-parse-errors-filename-function' can
+be used to transform filenames found in compilation output.
+
++++
+** 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.
+
+** 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.
+
+** `define-key-after' now accepts keys longer than 1.
+
+** `define-derived-mode' now accepts nil as the parent.
+
+** The local variable `no-byte-compile' in elisp files is now obeyed.
+
+** New functions `keymap-prompt' and `current-active-maps'.
+
+** New function `describe-buffer-bindings'.
+
+** New vars `exec-suffixes' and `load-suffixes' used when
+searching for an executable resp. an elisp file.
+
+** Variable aliases have been implemented
+
+- Macro: defvaralias ALIAS-VAR BASE-VAR
+
+This defines the symbol ALIAS-VAR as a variable alias for symbol
+BASE-VAR. This means that retrieving the value of ALIAS-VAR returns
+the value of BASE-VAR, and changing the value of ALIAS-VAR changes the
+value of BASE-VAR.
+
+- Function: indirect-variable VARIABLE
+
+This function returns the variable at the end of the chain of aliases
+of VARIABLE. If VARIABLE is not a symbol, or if VARIABLE is not
+defined as an alias, the function returns VARIABLE.
+
+It might be noteworthy that variables aliases work for all kinds of
+variables, including buffer-local and frame-local variables.
+
+** Functions from `post-gc-hook' are run at the end of garbage
+collection. The hook is run with GC inhibited, so use it with care.
+
+** If the second argument to `copy-file' is the name of a directory,
+the file is copied to that directory instead of signaling an error.
+
+** The variables most-positive-fixnum and most-negative-fixnum
+have been moved from the CL package to the core.
+
+** 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 packages:
+
+*** The new package syntax.el provides an efficient way to find the
+current syntactic context (as returned by parse-partial-sexp).
+
+*** The TCL package tcl-mode.el was replaced by tcl.el.
+This was actually done in Emacs-21.1, and was not documented.
+
+*** The new package Ibuffer provides a powerful, completely
+customizable replacement for buff-menu.el.

non-nil.
+** File selection dialog on MS-Windows is supported.
+
+When a file is visited by clicking File->Open, the MS-Windows version
+now pops up a standard file selection dialog where you can select a
+file to visit. File->Save As also pops up that dialog.
+
** Toolkit scroll bars.
Emacs now uses toolkit scroll bars if available. When configured for
icons will be used.
To make the tool bar more useful, we need contributions of extra icons
-for specific modes (with copyright assignments). Contributions would
-also be useful to touch up some of the PBM icons manually.

-
-- Mouse-2 on the buffer-name switches to the next buffer, and
-M-mouse-2 switches to the previous buffer in the buffer list.
+- Mouse-1 on the buffer name in the mode line goes to the next buffer.
-- Mouse-3 on the buffer-name displays a buffer menu.

code when called with a prefix argument.
** CC mode changes.
** The variable mail-specify-envelope-from controls whether to
use the -f option when sending mail.
+** The Rmail command `o' (`rmail-output-to-rmail-file') now writes the
+current message in the internal `emacs-mule' encoding, rather than in
+the encoding taken from the variable `buffer-file-coding-system'.
+This allows to save messages whose characters cannot be safely encoded
+by the buffer's coding system, and makes sure the message will be
+displayed correctly when you later visit the target Rmail file.
+
+If you want your Rmail files be encoded in a specific coding system
+other than `emacs-mule', you can customize the variable
+`rmail-file-coding-system' to set its value to that coding system.

** Changes to TeX mode
*** The default mode has been changed from `plain-tex-mode' to

+ matches character CHAR literally.
+
+`not-newline'
+ matches any character except a newline.
+ .
+`anything'
+ matches any character
+
+`(any SET)'
+ matches any character in SET. SET may be a character or string.
+ Ranges of characters can be specified as `A-Z' in strings.
