* Installation Changes in Emacs 21.1
** Support for GNU/Linux on IA64 machines has been added.

* 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,
** LessTif support.
-Emacs now runs with the LessTif toolkit (see <http://www.lesstif.org>).
-You will need a version 0.88.1 or later.

+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.
*** The new user option `rmail-automatic-folder-directives' specifies
in which folder to put messages automatically.
+*** The new function `rmail-redecode-body' allows to fix a message
+with non-ASCII characters if Emacs happens to decode it incorrectly
+due to missing or malformed "charset=" header.
+
** Changes to TeX mode
*** The default mode has been changed from `plain-tex-mode' to
*** 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

* Incompatible Lisp changes
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.
** `scroll-left' and `scroll-right' are only effective when
`automatic-hscrolling' is nil.
-\f
+
* 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.
+
+++
** The new user-option `even-window-heights' can be set to nil
to prevent `display-buffer' from evening out window heights.
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
+`after-change-function' are no longer acted upon and have been

for Unicode characters in the range U+0100..U+24FF, U+2500..U+33FF,
U+E000..U+FFFF respectively.
+** The new coding system `mule-utf-8' is added. It provides a limited
+support for decoding/encoding UTF-8 text. For the details, please see
+the documentation string of this coding system.
+
** The new character sets `japanese-jisx0213-1' and
`japanese-jisx0213-2' are introduced for the new Japanese standard JIS
X 0213 Plane 1 and Plane 2.
*** There is a new variable `strings-consed' holding the number of
strings that have been consed so far.

* Lisp-level Display features added after release 2.6 of the Emacs
Lisp Manual
** Image specifications may contain the property `:ascent center' (see
below).

* Changes in Emacs 20.4
** Init file may be called .emacs.el.
*** ispell4.el has been deleted. It got in the way of ispell.el and
this was hard to fix reliably. It has long been obsolete -- use
Ispell 3.1 and ispell.el.

facilitate working with version-controlled files from Lisp programs.
These macros check out a given file automatically if needed, and check
it back in after any modifications have been made.
-\f
+
* Installation Changes in Emacs 20.3
** The default value of load-path now includes most subdirectories of
GCC. This was formerly used to help compile Emacs with C compilers
that had limits on the significant length of an identifier, but in
fact we stopped supporting such compilers some time ago.

* Lisp changes in Emacs 20.3 since the Emacs Lisp Manual was published
** If you want a Lisp file to be read in unibyte mode,
non-ASCII characters; print-escape-multibyte applies to multibyte
characters. Both of these variables are used only when printing
in readable fashion (prin1 uses them, princ does not).

** Compiled Emacs Lisp files made with the modified "MBSK" version
instance, if you set up a special key binding for a specific language
environment by set-language-environment-hook, you should set up
exit-language-environment-hook to restore the normal key binding.
