* Changes in Emacs 21.1
** The user option `backward-delete-char-untabify-method' controls the
** 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.

*** 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

* 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.
+`(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)
** `scroll-left' and `scroll-right' are only effective when
`automatic-hscrolling' is nil.

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

it back in after any modifications have been made.

* 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.
