+finnish-alt-postfix, german-alt-postfix, icelandic-alt-postfix,

+
\f
* Installation Changes in Emacs 22.2
+** Emacs is now licensed under the GNU GPL version 3 (or later).
+
+** 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
+
+*** Deprecated operating systems

* Changes in Emacs 22.2
-** The values of `dired-recursive-deletes' and `dired-recursive-copies'
-have been changed to `top'. This means that the user is asked once,
-before deleting/copying the indicated directory recursively.
+** `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
+like that, customize the value of the new option `find-name-arg'.
** In Image mode, whenever the displayed image is wider and/or higher
than the window, the usual keys for moving the cursor cause the image
to be scrolled horizontally or vertically instead.
+** Emacs can use stock icons in the tool bar when compiled with Gtk+.
+However, this feature is disabled by default. To enable it, put
+
+ (setq icon-map-list '(x-gtk-stock-map))
+
+in your .emacs or some other startup file. For more information, see
+the documentation for the two variables icon-map-list and x-gtk-stock-map.
+
** Scrollbars follow the system theme on Windows XP and later.
Windows XP introduced themed scrollbars, but applications have to take
special steps to use them. Emacs now has the appropriate resources linked
in to make it use the scrollbars from the system theme.
+** focus-follows-mouse defaults to nil on MS Windows.
+Previously this variable was incorrectly documented as having no effect
+on MS Windows, and the default was inappropriate for the majority of
+Windows installations. Users of software which modifies the behavior of
+Windows to cause focus to follow the mouse will now need to explicitly set
+this variable.
+
+** `bad-packages-alist' will warn about external packages that are known
+to cause problems in this version of Emacs.
+
+** The values of `dired-recursive-deletes' and `dired-recursive-copies'
+have been changed to `top'. This means that the user is asked once,
+before deleting/copying the indicated directory recursively.
+
+** `browse-url-emacs' loads a URL into an Emacs buffer. Handy for *.el URLs.
+
+** The command gdba has been removed as gdb works now for those cases where it
+was needed. In text command mode, if you have problems before execution has
+started, use M-x gud-gdb.
+
+** desktop.el now detects conflicting uses of the desktop file.
+When loading the desktop, desktop.el can now detect that the file is already
+in use. The default behavior is to ask the user what to do, but you can
+customize it with the new option `desktop-load-locked-desktop'. When saving,
+desktop.el warns about attempts to overwrite a desktop file if it determines
+that the desktop being saved is not an update of the one on disk.
+
+** Compilation mode now correctly respects the value of
+`compilation-scroll-output' between invocations. Previously, output
+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.
+
** The new package css-mode.el provides a major mode for editing CSS files.
** The new package vera-mode.el provides a major mode for editing Vera files.
+** The new package verilog-mode.el provides a major mode for editing Verilog files.
+
** The new package socks.el implements the SOCKS v5 protocol.
** VC
-*** VC has some support for Mercurial (hg).
+*** VC backends can provide completion of revision names.
+
+*** 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).
+
+*** VC has some support for Monotone (Mtn).
+
+*** VC has some support for Bazaar (Bzr).
+
+*** VC has some support for Git.
+
+* Incompatible Lisp Changes in Emacs 22.2
+
+** shell.el no longer defines the aliases `dirtrack-toggle' and
+`dirtrack-mode' for `shell-dirtrack-mode'. These names were removed
+because they clash with commands provided by dirtrack.el. Use
+`shell-dirtrack-mode' instead.
+
+* Lisp Changes in Emacs 22.2.
+
+** Frame-local variables are deprecated and are slated for removal.
+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.
+
+** New function `window-full-width-p' returns t if a window is as wide
+as its frame.
+
+** The new function `image-refresh' refreshes all images associated
+with a given image specification.
+
+** The new function `combine-and-quote-strings' concatenates a list of strings
+using a specified separator. If a string contains double quotes, they
+are escaped in the output.
+
+** The new function `split-string-and-unquote' performs the inverse operation to
+`combine-and-quote-strings', i.e. splits a single string into a list
+of strings, undoing any quoting added by `combine-and-quote-strings'.
+(For some separator/string combinations, the original strings cannot
+be recovered.)
