+Fixme: The notes about Emacs 23 are quite incomplete.
+
+\f
+* Changes in Emacs 23.1
+
+** The Emacs character set is now a superset of Unicode.
+(It has about four times the code space, which should be plenty).
+
+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.
+
+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.
+
+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.
+
+** There are assorted new coding systems/aliases -- see
+M-x list-coding-systems.
+
+** New charset implementation with many new charsets.
+See M-x list-character-sets. New charsets can be defined conveniently
+as tables of unicodes.
+
+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.
+
+Generic characters no longer exist.
+
+A dynamic charset priority list is used to infer the charset of
+unicodes for display &c.
+
+** The following facilities are obsolete:
+
+Minor modes: unify-8859-on-encoding-mode, unify-8859-on-decoding-mode
+
+\f
+* Lisp changes in Emacs 23.1
+
+map-char-table's behaviour has changed.
+
+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.
+
+Changed functions: copy-sequence, decode-char, encode-char,
+set-fontset-font, new-fontset, modify-syntax-entry, define-charset,
+modify-category-entry
+
+Obsoleted: char-bytes, chars-in-region, set-coding-priority,
+char-valid-p
+
+\f
+* Incompatible Lisp changes
+
+Deleted functions: make-coding-system, register-char-codings,
+coding-system-spec
+
+** The character codes for characters from the
+eight-bit-control/eight-bit-graphic charsets aren't now in the range
+128-255.
\f
* Installation Changes in Emacs 22.1
contents of buffers from a core dump and save them to files easily, should
emacs crash.
+---
+** The Emacs terminal emulation in term.el uses a different terminfo name.
+The Emacs terminal emulation in term.el now uses "eterm-color" as its
+terminfo name, since term.el now supports color.
+
\f
* Startup Changes in Emacs 22.1
`inhibit-startup-message' (which is also aliased as
`inhibit-splash-screen').
++++
+** The default is now to use an bitmap as the icon, so the command-line options
+--icon-type, -i has been replaced with options --no-bitmap-icon, -nbi to turn
+the bitmap icon off.
+
+++
** New user option `inhibit-startup-buffer-menu'.
When loading many files, for instance with `emacs *', Emacs normally
controls whether or not the function `make-auto-save-file-name' will
attempt to construct a unique auto-save name (e.g. for remote files).
++++
+*** The new option `write-region-inhibit-fsync' disables calls to fsync
+in `write-region'. This can be useful on laptops to avoid spinning up
+the hard drive upon each file save. Enabling this variable may result
+in data loss, use with care.
+
+++
*** If the user visits a file larger than `large-file-warning-threshold',
Emacs asks for confirmation.
parts less visible than normal, so that the rest of the differing
parts is, by contrast, slightly highlighted.
+Above fontification is always done when listing completions is
+triggered at minibuffer. If you want to fontify completions whose
+listing is triggered at the other normal buffer, you have to pass
+the common prefix of completions to `display-completion-list' as
+its second argument.
+
+++
*** File-name completion can now ignore specified directories.
If an element of the list in `completion-ignored-extensions' ends in a
** Customize changes:
++++
+*** Custom themes are collections of customize options. Create a
+custom theme with M-x customize-create-theme. Use M-x load-theme to
+load and enable a theme, and M-x disable-theme to disable it. Use M-x
+enable-theme to renable a disabled theme.
+
+++
*** The commands M-x customize-face and M-x customize-face-other-window
now look at the character after point. If a face or faces are
\f
* New Modes and Packages in Emacs 22.1
+** Rcirc is now part of the Emacs distribution.
+
+Rcirc is an Internet relay chat (IRC) client. It supports
+simultaneous connections to multiple IRC servers. Each discussion
+takes place in its own buffer. For each connection you can join
+several channels (many-to-many) and participate in private
+(one-to-one) chats. Both channel and private chats are contained in
+separate buffers.
+
+To start an IRC session, type M-x irc, and follow the prompts for
+server, port, nick and initial channels.
+
+---
+** Newsticker is now part of the Emacs distribution.
+
+Newsticker asynchronously retrieves headlines (RSS) from a list of news
+sites, prepares these headlines for reading, and allows for loading the
+corresponding articles in a web browser. Its documentation is in a
+separate manual.
+
++++
+** savehist saves minibuffer histories between sessions.
+
+++
** Filesets are collections of files. You can define a fileset in
various ways, such as based on a directory tree or based on
\f
* Changes in Specialized Modes and Packages in Emacs 22.1:
+** Changes in Allout
+
+*** Topic cryptography added, enabling easy gpg topic encryption and
+decryption. Per-topic basis enables interspersing encrypted-text and
+clear-text within a single file to your hearts content, using symmetric
+and/or public key modes. Time-limited key caching, user-provided
+symmetric key hinting and consistency verification, auto-encryption of
+pending topics on save, and more, make it easy to use encryption in
+powerful ways.
+
+*** many substantial fixes and refinements, including:
+
+ - repaired inhibition of inadvertant edits to concealed text
+ - repaired retention of topic body hanging indent upon topic depth shifts
+ - prevent "containment discontinuities" where a topic is shifted deeper
+ than the offspring-depth of its' container
+ - easy to adopt the distinctive bullet of a topic in a topic created
+ relative to it, or select a new one, or use the common topic bullet
+ - plain bullets, by default, now alternate between only two characters
+ ('.' and ','), yielding less cluttered outlines.
+ - many internal fixes.
+
+** The variable `woman-topic-at-point' was renamed
+to `woman-use-topic-at-point' and behaves differently: if this
+variable is non-nil, the `woman' command uses the word at point
+automatically, without asking for a confirmation. Otherwise, the word
+at point is suggested as default, but not inserted at the prompt.
+
---
** Changes to cmuscheme
enabled. The new option `recentf-auto-cleanup' controls when to do
automatic cleanup.
+The ten most recent files can be quickly opened by using the shortcut
+keys 1 to 9, and 0, when the recent list is displayed in a buffer via
+the `recentf-open-files', or `recentf-open-more-files' commands.
+
The `recentf-keep' option replaces `recentf-keep-non-readable-files-p'
and provides a more general mechanism to customize which file names to
keep in the recent list.
-With the more advanced option: `recentf-filename-handler', you can
-specify a function that transforms filenames handled by recentf. For
-example, if set to `file-truename', the same file will not be in the
-recent list with different symbolic links.
+With the more advanced option `recentf-filename-handlers', you can
+specify functions that successively transform recent file names. For
+example, if set to `file-truename' plus `abbreviate-file-name', the
+same file will not be in the recent list with different symbolic
+links, and the file name will be abbreviated.
To follow naming convention, `recentf-menu-append-commands-flag'
replaces the misnamed option `recentf-menu-append-commands-p'. The

+Upgraded to MH-E version 7.85. There have been major changes since
version 5.0.2; see MH-E-NEWS for details.
** Calendar changes:
`diary-outlook-formats' can be customized to recognize additional
formats.
++++
+** Speedbar changes:
+
+*** Speedbar items can now be selected by clicking mouse-1, based on
+the `mouse-1-click-follows-link' mechanism.
+
+*** SPC and DEL are no longer bound to scroll up/down in the speedbar
+keymap.
+
+*** The new command `speedbar-toggle-line-expansion', bound to SPC,
+contracts or expands the line under the cursor.
+
+*** New command `speedbar-create-directory', bound to `M'.
+
+*** The new commands `speedbar-expand-line-descendants' and
+`speedbar-contract-line-descendants', bound to `[' and `]'
+respectively, expand and contract the line under cursor with all of
+its descendents.
+
+*** The new user option `speedbar-query-confirmation-method' controls
+how querying is performed for file operations. A value of 'always
+means to always query before file operations; 'none-but-delete means
+to not query before any file operations, except before a file
+deletion.
+
+*** The new user option `speedbar-select-frame-method' specifies how
+to select a frame for displaying a file opened with the speedbar. A
+value of 'attached means to use the attached frame (the frame that
+speedbar was started from.) A number such as 1 or -1 means to pass
+that number to `other-frame'.
+
+*** The new user option `speedbar-use-tool-tips-flag', if non-nil,
+means to display tool-tips for speedbar items.
+
+*** The frame management code in speedbar.el has been split into a new
+`dframe' library. Emacs Lisp code that makes use of the speedbar
+should use `dframe-attached-frame' instead of
+`speedbar-attached-frame', `dframe-timer' instead of `speedbar-timer',
+`dframe-close-frame' instead of `speedbar-close-frame', and
+`dframe-activity-change-focus-flag' instead of
+`speedbar-activity-change-focus-flag'. The variables
+`speedbar-update-speed' and `speedbar-navigating-speed' are also
+obsolete; use `dframe-update-speed' instead.
+

** sql changes.
with other details of skeleton construction.
---
-** New variable `hs-set-up-overlay' allows customization of the overlay
+** Hideshow mode changes
+
+*** New variable `hs-set-up-overlay' allows customization of the overlay
used to effect hiding for hideshow minor mode. Integration with isearch
handles the overlay property `display' specially, preserving it during
temporary overlay showing in the course of an isearch operation.
+*** New variable `hs-allow-nesting' non-nil means that hiding a block does
+not discard the hidden state of any "internal" blocks; when the parent
+block is later shown, the internal blocks remain hidden. Default is nil.
+
+++
** `hide-ifdef-mode' now uses overlays rather than selective-display
to hide its text. This should be mostly transparent but slightly
for compatibility, an internal variable which exists only for this
purpose.
++++
+*** The function `read-buffer' follows the convention for reading from
+the minibuffer with a default value: if DEF is non-nil, the minibuffer
+prompt provided in PROMPT is edited to show the default value provided
+in DEF before the terminal colon and space.
+
** Local variables lists:
+++
This is useful for autoloaded handlers, to prevent them from being
autoloaded when not really necessary.
++++
+*** The function `make-auto-save-file-name' is now handled by file
+name handlers. This will be exploited for remote files mainly.
+
** Input changes:
+++
If non-nil, that says to preserve the window's current margin, fringe,
and scroll-bar settings.
++++
+*** The new function `window-tree' returns a frame's window tree.
+
+++
** Customizable fringe bitmaps
an event is composed by combining the ID of the hot-spot with the
mouse event, e.g. [area4 mouse-1] if the hot-spot's ID is `area4'.
++++
+*** The function `find-image' now searches in etc/images/ and etc/.
+The new variable `image-load-path' is a list of locations in which to
+search for image files. The default is to search in etc/images, then
+in etc/, and finally in the directories specified by `load-path'.
+Subdirectories of etc/ and etc/images are not recursively searched; if
+you put an image file in a subdirectory, you have to specify it
+explicitly; for example, if an image is put in etc/images/foo/bar.xpm:
+
+ (defimage foo-image '((:type xpm :file "foo/bar.xpm")))
+
++++
+*** The new variable `max-image-size' defines the maximum size of
+images that Emacs will load and display.
+
** Mouse pointer features:
+++ (lispref)
so that :inherit face lists operate identically to face lists in text
`face' properties.
+---
+*** On terminals, faces with the :inverse-video attribute are displayed
+with swapped foreground and background colors even when one of them is
+not specified. In previous releases of Emacs, if either foreground
+or background color was unspecified, colors were not swapped. This
+was inconsistent with the face behavior under X.
+

*** `set-fontset-font', `fontset-info', `fontset-font' now operate on
the default fontset if the argument NAME is nil..
