+* Changes in Emacs 21.3
+
+** The obsolete C mode (c-mode.el) has been removed to avoid problems
+with Custom.
+
+** UTF-16 coding systems are available, encoding the same characters
+as mule-utf-8.  Coding system `utf-16-le-dos' is useful as the value
+of `selection-coding-system' in MS Windows, allowing you to paste
+multilingual text from the clipboard.  Set it interactively with
+C-x RET x or in .emacs with `(set-selection-coding-system 'utf-16-le-dos)'.
+
+** There is a new language environment for UTF-8 (set up automatically
+in UTF-8 locales).
+
+** Translation tables are available between equivalent characters in
+different Emacs charsets -- for instance `e with acute' coming from the
+Latin-1 and Latin-2 charsets.  User options `unify-8859-on-encoding-mode'
+and `unify-8859-on-decoding-mode' respectively turn on translation
+between ISO 8859 character sets (`unification') on encoding
+(e.g. writing a file) and decoding (e.g. reading a file).  Note that
+`unify-8859-on-encoding-mode' is useful and safe, but
+`unify-8859-on-decoding-mode' can cause text to change when you read
+it and write it out again without edits, so it is not generally advisable.
+By default `unify-8859-on-encoding-mode' is turned on.
+
+** In Emacs running on the X window system, the default value of
+`selection-coding-system' is now `compound-text-with-extensions'.
+
+If you want the old behavior, set selection-coding-system to
+compound-text, which may be significantly more efficient.  Using
+compound-text-with-extensions seems to be necessary only for decoding
+text from applications under XFree86 4.2, whose behaviour is actually
+contrary to the compound text specification.

+* Changes in Emacs 21.2
+
+** Emacs now supports compound-text extended segments in X selections.
+
+X applications can use `extended segments' to encode characters in
+compound text that belong to character sets which are not part of the
+list of approved standard encodings for X, e.g. Big5.  To paste
+selections with such characters into Emacs, use the new coding system
+compound-text-with-extensions as the value of selection-coding-system.
+
+** 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.
+
+** 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.
+
+** The new option `Info-scroll-prefer-subnodes' causes Info to behave
+like the stand-alone Info reader (from the GNU Texinfo package) as far
+as motion between nodes and their subnodes is concerned.  If it is t
+(the default), Emacs behaves as before when you type SPC in a menu: it
+visits the subnode pointed to by the first menu entry.  If this option
+is nil, SPC scrolls to the end of the current node, and only then goes
+to the first menu item, like the stand-alone reader does.
+
+This change was already in Emacs 21.1, but wasn't advertised in the
+NEWS.
