* Changes in Emacs 21.1
+** The user option `backward-delete-char-untabify-method' controls the
+behaviour of `backward-delete-char-untabify'. [This change was made
+in Emacs 20.3 but not mentioned then.]
+
+** The new user-option `confirm-kill-emacs' can be customized to
+let Emacs ask for confirmation before exiting.
+
+** The <home> and <end> keys now move to the beginning or end of the
+current line, respectively. C-<home> and C-<end> move to the
+beginning and end of the buffer.
+
** In Cperl mode `cperl-invalid-face' should now be a normal face
symbol, not double-quoted.
** Variable `load-path' is no longer customizable because it contains
a version-dependent component.
-** The new user-option `delete-key-deletes-forward' can be set to
+** The new user-option `delete-key-deletes-forward' can be set to
let the Delete function key delete forward instead of backward.
On window systems, the default value of this option is chosen
** The mode line under X is now drawn with shadows by default.
You can change its appearance by modifying the face `mode-line'.
+In particular, setting the `:box' attribute to nil turns off the 3D
+appearance of the mode line. (The 3D appearance makes the mode line
+occupy more space, and thus might cause the first or the last line of
+the window to be partially obscured.)
The variable `mode-line-inverse-video', which was used in older
versions of emacs to make the mode-line stand out, now defaults to nil,
- Mouse-2 on the read-only or modified status in the mode line (`%' or
`*') toggles the status.
-- Mouse-3 on the mode name display a minor-mode menu.
+- Mouse-3 on the mode name displays a minor-mode menu.
** LessTif/Motif file selection dialog.
*** The new function `font-lock-remove-keywords' can be used to remove
font-lock keywords from the current buffer or from a specific major mode.
-*** multiline patterns are now supported.
+*** Multiline patterns are now supported. Modes using this, should
+set font-lock-multiline to t in their font-lock-defaults.
*** `font-lock-syntactic-face-function' allows major-modes to choose
the face used for each string/comment.
*** In Lisp, "(defstruct (foo", "(defun (operator" and similar constructs
are now tagged.
+*** In makefiles, tags the targets.
+
*** In Perl, the --globals option tags global variables. my and local
variables are tagged.
releases have 8859-15. There are new Latin-8 and Latin-9 prefix
(only) and Polish slash input methods in Leim.

+** New language environments `Dutch' and `Spanish'.
+These new environments mainly select appropriate translations
+of the tutorial.

** Fortran mode has a new command `fortran-strip-sequence-nos' to
remove text past column 72. The syntax class of `\' in Fortran is now
you need to put it somewhere into Emacs' load path and add the atom
`FOO' to the list `vc-handled-backends'.
+*** The customizable EDT emulation package now supports the EDT
+SUBS command and EDT scroll margins. It also works with more
+terminal/keyboard configurations and it now works under XEmacs.
+See etc/edt-user.doc for more information.
+
** New modes and packages
*** The new global minor mode `minibuffer-electric-default-mode'
*** ansi-color.el translates ANSI terminal escapes into text-properties.
-Please note: if `ansi-color-for-shell-mode' and
+Please note: if `ansi-color-for-comint-mode and
`global-font-lock-mode' are non-nil, loading ansi-color.el will
disable font-lock and add `ansi-color-apply' to
`comint-preoutput-filter-functions' for all shell-mode buffers. This

*** fortune.el uses the fortune program to create mail/news signatures.
-*** whitespace.el ???
+*** whitespace.el is a package for warning about and cleaning bogus
+whitespace in a file.
*** PostScript mode (ps-mode) is a new major mode for editing PostScript
files. It offers: interaction with a PostScript interpreter, including
There are a few Lisp changes which are not backwards-compatible and
may require changes to existing code. Here is a list for reference.
+See the sections below for details.
-** Since `format' preserves text properties, the idiom
-`(format %s foo)' no longer works to remove properties.
+** Since `format' preserves text properties, the idiom
+`(format %s foo)' no longer works to copy and remove properties.
+Use `copy-sequence' and `set-text-properties'.
** Since the `keymap' text property now has significance, some code
which uses both `local-map' and `keymap' properties (for portability)
appropriate for reading truly binary files.
** Code that relies on the obsolete `before-change-function' and
-`after-change-function' to detect buffer changes will now fail.
+`after-change-function' to detect buffer changes will now fail. Use
+`before-change-functions' and `after-change-functions' instead.
** Code that uses `concat' with integer args now gets an error, as
long promised.
* Lisp changes made after edition 2.6 of the Emacs Lisp Manual,
(Display-related features are described in a page of their own below.)
+** The new hook `kbd-macro-termination-hook' is run at the end of of
+function execute-kbd-macro. Functions on this hook are called with no
+args. The hook is run independent of how the macro was terminated
+(signal or normal termination).
+

** Functions `butlast' and `nbutlast' for removing trailing elements
from a list are now available without requiring the CL package.
with the more general `:mask' property.
+++
-** Image specifications accept more `:algorithm's.
+** Image specifications accept more `:conversion's.
** A `?' can be used in a symbol name without escaping it with a
backslash.
This is probably what most current uses of `local-map' want, rather
than replacing the local map.
-** The obsolete variables before-change-function and
-after-change-function are no longer acted upon and have been removed.
+** The obsolete variables `before-change-function' and

** The function `apropos-mode' runs the hook `apropos-mode-hook'.
Setting `face-font-family-alternatives' allows the user to specify
alternative font families to try if a family specified by a face

Setting `face-font-registry-alternatives' allows the user to specify

`:margin MARGIN'
-MARGIN must be a number >= 0 specifying how many pixels to put as
-margin around the image. Default is 0.
+MARGIN must be either a number >= 0 specifying how many pixels to put
+as margin around the image, or a pair (X . Y) with X specifying the
+horizontal margin and Y specifying the vertical margin. Default is 0.
`:relief RELIEF'
RELIEF is analogous to the `:relief' attribute of faces. Puts a relief
around an image.
-`:algorithm ALGO'
+`:conversion ALGO'
Apply an image algorithm to the image before displaying it.
You can add extra space between tool bar items by setting
`tool-bar-button-margin' to a positive integer specifying a number of
-pixels. Default is 1.

You can change the shadow thickness of tool bar buttons by setting
`tool-bar-button-relief' to an integer. Default is 3.
