+* About external Lisp packages
-Temporary note:
- +++ indicates that the appropriate manual has already been updated.
- --- means no change in the manuals is called for.
-When you add a new item, please add it without either +++ or ---
-so we will look at it and add it to the manual.
+When you upgrade to Emacs 22 from a previous version, some older
+versions of external Lisp packages are known to behave badly.
+So in general, it is recommended that you upgrade to the latest
+versions of any external Lisp packages that you are using.
-Fixme: The notes about Emacs 23 are quite incomplete.
+You should also be aware that many Lisp packages have been included
+with Emacs 22 (see the extensive list below), and you should remove
+any older versions of these packages to ensure that the Emacs 22
+version is used. You can use M-x list-load-path-shadows to find such
+older packages.
+
+Some specific packages that are known to cause problems are given
+below. Emacs tries to warn you about these through `bad-packages-alist'.
+
+** Semantic (used by CEDET, ECB, JDEE): upgrade to latest version.
+
+** cua.el, cua-mode.el: remove old versions.

+
+*** Support for systems without alloca will be removed.
+
+*** Support for Sun windows will be removed.
+
+*** Support for VMS will be removed.
+
+* Incompatible Editing Changes in Emacs 22.3
+
+** The following input methods were removed in Emacs 22.2, but this was
+not advertised: danish-alt-postfix, esperanto-alt-postfix,
+finnish-alt-postfix, german-alt-postfix, icelandic-alt-postfix,
+norwegian-alt-postfix, scandinavian-alt-postfix, spanish-alt-postfix,
+and swedish-alt-postfix. Use the versions without "alt-", which are
+identical.
-** The Emacs character set is now a superset of Unicode.
-(It has about four times the code space, which should be plenty).
+\f
+* Installation Changes in Emacs 22.2
-The internal encoding used for buffers and strings is now
-Unicode-based and called `utf-8-emacs'. utf-8-emacs is backwards
-compatible with the UTF-8 encoding of Unicode. The `emacs-mule'
-coding system can still read and write data in the old internal
-encoding.
+** Emacs is now licensed under the GNU GPL version 3 (or later).
-There are still charsets which contain disjoint sets of characters
-where this is necessary or useful, especially for various Far Eastern
-sets which are problematic with Unicode.
+** Support for GNU/kFreeBSD (GNU userland and FreeBSD kernel) was added.
-Since the internal encoding is also used by default for byte-compiled
-files -- i.e. the normal coding system for byte-compiled Lisp files is
-now utf-8-Emacs -- Lisp containing non-ASCII characters which is
-compiled by Emacs 23 can't be read by earlier versions of Emacs. Files
-compiled by Emacs 20, 21, or 22 are loaded correctly as emacs-mule
-(whether or not they contain multibyte characters), which makes loading
-them somewhat slower than Emacs 23-compiled files. Thus it may be worth
-recompiling existing .elc files which don't need to be shared with older
-Emacsen.
+** Deprecated machine types and operating systems
-** There are assorted new coding systems/aliases -- see
-M-x list-coding-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.
-** New charset implementation with many new charsets.
-See M-x list-character-sets. New charsets can be defined conveniently
-as tables of unicodes.
+*** Deprecated machine types
+pmax, hp9000s300, ibm370aix, ncr386, ews4800, mips-siemens, powerpcle,
+and tandem-s2
-The dimension of a charset is now 0, 1, 2, or 3, and the size of each
-dimension is no longer limited to 94 or 96.
+*** Deprecated operating systems
+bsd386, bsdos2-1, bsdos2, bsdos3, bsdos4, bsd4-1, bsd4-2, bsd4-3,
+usg5-0, usg5-2-2, usg5-2, usg5-3, ultrix4-3, 386bsd, hpux, hpux8,
+hpux9, hpux9shr, hpux10, hpux10-20, aix3-1, aix3-2-5, aix3-2, aix4-1,
+nextstep, ux4800, uxpds, and uxpv
-Generic characters no longer exist.
+* Changes in Emacs 22.2
-A dynamic charset priority list is used to infer the charset of
-unicodes for display &c.
+** `describe-project' is renamed to `describe-gnu-project'.
-** The following facilities are obsolete:
+** `view-todo' is renamed to `view-emacs-todo'.
-Minor modes: unify-8859-on-encoding-mode, unify-8859-on-decoding-mode
+** `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'.
-\f
-* Lisp changes in Emacs 23.1
+** 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.
-map-char-table's behaviour has changed.
+** Emacs can use stock icons in the tool bar when compiled with Gtk+.
+However, this feature is disabled by default. To enable it, put
-New functions: characterp, max-char, map-charset-chars,
-define-charset-alias, primary-charset, set-primary-charset,
-unify-charset, clear-charset-maps, charset-priority-list,
-set-charset-priority, define-coding-system,
-define-coding-system-alias, coding-system-aliases, langinfo,
-string-to-multibyte.
+ (setq icon-map-list '(x-gtk-stock-map))
-Changed functions: copy-sequence, decode-char, encode-char,
-set-fontset-font, new-fontset, modify-syntax-entry, define-charset,
-modify-category-entry
+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.
-Obsoleted: char-bytes, chars-in-region, set-coding-priority,
-char-valid-p
+** 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.
-\f
-* Incompatible Lisp changes
+** 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.
-Deleted functions: make-coding-system, register-char-codings,
-coding-system-spec
+** `bad-packages-alist' will warn about external packages that are known
+to cause problems in this version of Emacs.
-** The character codes for characters from the
-eight-bit-control/eight-bit-graphic charsets aren't now in the range
-128-255.
-\f
-* About external Lisp packages
+** 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.
-When you upgrade to Emacs 22 from a previous version, some older
-versions of external Lisp packages are known to behave badly.
-So in general, it is recommended that you upgrade to the latest
-versions of any external Lisp packages that you are using.
+** `browse-url-emacs' loads a URL into an Emacs buffer. Handy for *.el URLs.
-You should also be aware that many Lisp packages have been included
-with Emacs 22 (see the extensive list below), and you should remove
-any older versions of these packages to ensure that the Emacs 22
-version is used. You can use M-x list-load-path-shadows to find such
-older packages.
+** 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.
-Some specific packages that are known to cause problems are:
+** 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.
-** Semantic (used by CEDET, ECB, JDEE): upgrade to latest version.
+** 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.
-** cua.el, cua-mode.el: remove old versions.
+** `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 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.)
\f
* Installation Changes in Emacs 22.1
keymaps that are active in the minibuffer are described below under
"New keymaps for typing file names".
+If you want the old behavior back, add these two key bindings to your
+~/.emacs init file:
+
+ (define-key minibuffer-local-filename-completion-map
+ " " 'minibuffer-complete-word)
+ (define-key minibuffer-local-must-match-filename-map
+ " " 'minibuffer-complete-word)
+
** The completion commands TAB, SPC and ? in the minibuffer apply only
to the text before point. If there is text in the buffer after point,
it remains unchanged.
doublequotes make no difference in the shell, but they prevent
special treatment in `dired-do-shell-command'.
-** A prefix argument is no longer required to repeat a jump to a
-previous mark if you set `set-mark-command-repeat-pop' to t. I.e. C-u
-C-SPC C-SPC C-SPC ... cycles through the mark ring. Use C-u C-u C-SPC

+applies to file buffers. For non-file buffers, the behavior can be mode

If you are sure that the file will only change by growing at the end,
then you can tail the file more efficiently by using the new minor
breakpoints.
