** Support for GNU/kFreeBSD (GNU userland and FreeBSD kernel) was added.
+** Deprecated machine types and operating systems
+
+Certain machine types and operating systems have been deprecated. On
+these systems, configure will print a warning and exit, and you must
+edit the configure script for compilation to proceed. The deprecated
+systems will not be supported at all in Emacs 23. We are not aware of
+anyone running Emacs on these systems; if you are, please email
+emacs-devel@gnu.org to take it off the list of deprecated systems.
+
+*** Deprecated machine types
+pmax, hp9000s300, ibm370aix, ncr386, ews4800, mips-siemens, powerpcle,
+and tandem-s2

* Changes in Emacs 22.2
+** `describe-project' is renamed to `describe-gnu-project'.
+
+** `view-todo' is renamed to `view-emacs-todo'.
+
** `find-name-dired' now uses -iname rather than -name
for case-insensitive filesystems. The default behavior is determined
by the value of `read-file-name-completion-ignore-case'; if you don't
was mistakenly scrolled on compiles after the first. Customize
`compilation-scroll-output' if you want to retain the scrolling.
+** `font-lock-comment-face' no longer differs from the default on
+displays with fewer than 16 colors and dark background (e.g. older
+xterms and the Linux console). On such displays, only the comment
+delimiters will appear to be fontified (in the new face
+`font-lock-comment-delimiter-face'). To restore the old appearance,
+customize `font-lock-comment-face'. Another alternative is to use a
+newer terminal emulator that supports more colors (256 is now common).
+For example, for xterm compatible emulators that support 256 colors,
+you can run emacs like this:
+env TERM=xterm-256color emacs -nw
+(This was new in Emacs 22.1, but was not described. In Emacs 22.1
+this also happened for terminals with a light background, that is not
+the case anymore).
+
* New Modes and Packages in Emacs 22.2
** bibtex-style-mode helps you write BibTeX's *.bst files.
*** VC backends can provide completion of revision names.
-*** VC backends can provide extra menu entries to be added to the "Version Control" menu.
+*** VC backends can provide extra menu entries to the "Version Control" menu.
This can be used to add menu entries for backend specific functions.
*** VC has some support for Mercurial (Hg).
* Lisp Changes in Emacs 22.2.
** Frame-local variables are deprecated and are slated for removal.
-Use frame parameters instead.
+They can easily be emulated. Rather than calling `make-variable-frame-local'
+and accessing the variable value directly, explicitly check for a
+frame-parameter, and if there is one, use its value in preference to
+that of the variable. Note that buffer-local values should take
+precedence over frame-local ones, so you may wish to check `local-variable-p'
+first.
** The function invisible-p returns non-nil if the character
after a specified position is invisible.
-+++
** inhibit-modification-hooks is bound to t while running modification hooks.
As a happy consequence, after-change-functions and before-change-functions
are not bound to nil any more while running an (after|before)-change-function.
(For some separator/string combinations, the original strings cannot
be recovered.)
-* Systems that will not be supported in the future
-configure will print a warning and exit for a set of systems that are
-believed to not be in use anymore. The support has not been removed
-yet, but configure will need to be edited in order to allow
-compilation to proceed on such a system. If you are using such a
-system, please send a message to emacs-devel@gnu.org in order to take
-off the list of systems.

* Installation Changes in Emacs 22.1
`Info-mode-hook'.
*** New standard font-lock face `font-lock-comment-delimiter-face'.
+This is used for the characters that indicate the start of a comment,
+e.g. `;' in Lisp mode.
*** New standard font-lock face `font-lock-preprocessor-face'.
