+** 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.

* Startup Changes in Emacs 22.1
`inhibit-startup-message' (which is also aliased as
`inhibit-splash-screen').
++++
+** The default is now to use a 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
+++
** Init file changes
-You can now put the init files .emacs and .emacs_SHELL under
-~/.emacs.d or directly under ~. Emacs will find them in either place.
+If the init file ~/.emacs does not exist, Emacs will try
+~/.emacs.d/init.el or ~/.emacs.d/init.elc. You can also put the shell
+init file .emacs_SHELL under ~/.emacs.d.
+++
** Emacs now reads the standard abbrevs file ~/.abbrev_defs
+++
** A prefix argument is no longer required to repeat a jump to a
-previous mark, i.e. C-u C-SPC C-SPC C-SPC ... cycles through the
-mark ring. Use C-u C-u C-SPC to set the mark immediately after a jump.
+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
+to set the mark immediately after a jump.
+++
** The info-search bindings on C-h C-f, C-h C-k and C-h C-i
of specifying the current directory. Normally that means to visit the
directory with Dired.
+You can get the old behavior by typing C-x C-f M-n RET, which fetches
+the actual file name into the minibuffer.
+
+++
** 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.
++++
+** When Emacs prompts for file names, SPC no longer completes the file name.
+This is so filenames with embedded spaces could be input without the
+need to quote the space with a C-q. The underlying changes in the
+keymaps that are active in the minibuffer are described below under
+"New keymaps for typing file names".
+
+++
** M-o now is the prefix key for setting text properties;
M-o M-o requests refontification.
* Editing Changes in Emacs 22.1
+++
-** The max size of buffers and integers has been doubled.
-On 32bit machines, it is now 256M (i.e. 268435455).
-
-+++
-** M-g is now a prefix key.
-M-g g and M-g M-g run goto-line.
-M-g n and M-g M-n run next-error (like C-x `).
-M-g p and M-g M-p run previous-error.
-
-+++
-** C-u M-g M-g switches to the most recent previous buffer,
-and goes to the specified line in that buffer.
-
-When goto-line starts to execute, if there's a number in the buffer at
-point then it acts as the default argument for the minibuffer.
-
-+++
-** The old bindings C-M-delete and C-M-backspace have been deleted,
-since there are situations where one or the other will shut down
-the operating system or your X server.
-
-+++
-** line-move-ignore-invisible now defaults to t.
+** !MEM FULL! at the start of the mode line indicates that Emacs
+cannot get any more memory for Lisp data. This often means it could
+crash soon if you do things that use more memory. On most systems,
+killing buffers will get out of this state. If killing buffers does
+not make !MEM FULL! disappear, you should save your work and start
+a new Emacs.
+++
-** When the undo information of the current command gets really large
-(beyond the value of `undo-outer-limit'), Emacs discards it and warns
-you about it.
-
-+++
-** `apply-macro-to-region-lines' now operates on all lines that begin
-in the region, rather than on all complete lines in the region.
+** The max size of buffers and integers has been doubled.
+On 32bit machines, it is now 256M (i.e. 268435455).
+++
-** You can now switch buffers in a cyclic order with C-x C-left and
-(prev-buffer) and C-x C-right (next-buffer). C-x left and C-x right
-can be used as well.
+** You can now switch buffers in a cyclic order with C-x C-left
+(previous-buffer) and C-x C-right (next-buffer). C-x left and
+C-x right can be used as well. The functions keep a different buffer
+cycle for each frame, using the frame-local buffer list.
+++
** `undo-only' does an undo which does not redo any previous undo.
** New commands to operate on pairs of open and close characters:
`insert-pair', `delete-pair', `raise-sexp'.
----
++++
** New command `kill-whole-line' kills an entire line at once.
By default, it is bound to C-S-<backspace>.
C-h e displays the *Messages* buffer.
+C-h d runs apropos-documentation.
+
C-h followed by a control character is used for displaying files
that do not change:
have been moved to C-h F, C-h K and C-h S.
C-h c, C-h k, C-h w, and C-h f now handle remapped interactive commands.
-
- C-h c and C-h k report the actual command (after possible remapping)
run by the key sequence.
-
- C-h w and C-h f on a command which has been remapped now report the
command it is remapped to, and the keys which can be used to run
that command.
For example, if C-k is bound to kill-line, and kill-line is remapped
to new-kill-line, these commands now report:
-
- C-h c and C-h k C-k reports:
C-k runs the command new-kill-line
-
- C-h w and C-h f kill-line reports:
kill-line is remapped to new-kill-line which is on C-k, <deleteline>
-
- C-h w and C-h f new-kill-line reports:
new-kill-line is on C-k
preceded by one of the words `variable' or `option'. It now makes
hyperlinks to Info anchors (or nodes) if the anchor (or node) name is
enclosed in single quotes and preceded by `info anchor' or `Info
-anchor' (in addition to earlier `info node' and `Info node').
+anchor' (in addition to earlier `info node' and `Info node'). In
+addition, it now makes hyperlinks to URLs as well if the URL is
+enclosed in single quotes and preceded by `URL'.

+suffix from every line before processing all the lines.
+
++++
+*** If the local variables list contains any variable-value pairs that
+are not known to be safe, Emacs shows a prompt asking whether to apply
+the local variables list as a whole. In earlier versions, a prompt
+was only issued for variables explicitly marked as risky (for the
+definition of risky variables, see `risky-local-variable-p').
+
+At the prompt, the user can choose to save the contents of this local
+variables list to `safe-local-variable-values'. This new customizable
+option is a list of variable-value pairs that are known to be safe.
+Variables can also be marked as safe with the existing
+`safe-local-variable' property (see `safe-local-variable-p').
+However, risky variables will not be added to
+`safe-local-variable-values' in this way.
+++
*** find-file-read-only visits multiple files in read-only mode,
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.
** Minibuffer changes:
++++
+*** The new file-name-shadow-mode is turned ON by default, so that when
+entering a file name, any prefix which Emacs will ignore is dimmed.
+
+++
*** There's a new face `minibuffer-prompt'.
Emacs adds this face to the list of text properties stored in the
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
`auto-hscroll-mode'. The old name is still available as an alias.
---
-*** Moving or scrolling through images (and other lines) taller that
+*** Moving or scrolling through images (and other lines) taller than
the window now works sensibly, by automatically adjusting the window's
vscroll property.
*** The variable `cursor-in-non-selected-windows' can now be set to any
of the recognized cursor types.
++++
+*** On text terminals, the variable `visible-cursor' controls whether Emacs
+uses the "very visible" cursor (the default) or the normal cursor.
+
** New faces:
+++
elements on mode-line (and header-line) like `highlight' face on text
areas.
+*** `mode-line-buffer-id' is the standard face for buffer identification
+parts of the mode line.
+
+++
*** `shadow' face defines the appearance of the "shadowed" text, i.e.
the text which should be less noticeable than the surrounding text.
allows customization of the appearance of shadowed text in one place,
so package-specific faces can inherit from it.
++++
+*** `vertical-border' face is used for the vertical divider between windows.

** Font-Lock changes:

You can also move the vertical scroll bar to either side here or turn
it off completely. There is also a menu-item to toggle displaying of

-mode-line.
+current date and time, current line and column number in the mode-line.
---
*** Speedbar has moved from the "Tools" top level menu to "Show/Hide".
ESC, like they do for Gtk+, Mac and W32.
+++
-*** For Gtk+ version 2.4, you can make Emacs use the old file dialog
+*** For the Gtk+ version, you can make Emacs use the old file dialog
by setting the variable `x-use-old-gtk-file-dialog' to t. Default is to use
the new dialog.
** Mouse changes:
+++
-*** New display feature: focus follows the mouse from one Emacs window
-to another, even within a frame. If you set the variable
-mouse-autoselect-window to non-nil value, moving the mouse to a
-different Emacs window will select that window (minibuffer window can
-be selected only when it is active). The default is nil, so that this
-feature is not enabled.
+*** If you set the new variable `mouse-autoselect-window' to a non-nil
+value, windows are automatically selected as you move the mouse from
+one Emacs window to another, even within a frame. A minibuffer window
+can be selected only when it is active.
+++
*** On X, when the window manager requires that you click on a frame to

*** Under X, mouse-wheel-mode is turned on by default.
-** Mule changes:
+** Multilingual Environment (Mule) changes:
---
*** Language environment and various default coding systems are setup
Big 5 is then converted to CNS.
---
-*** Many new coding systems are available by loading the `code-pages'
-library. These include complete versions of most of those in
-codepage.el, based on Unicode mappings. `codepage-setup' is now
-obsolete and is used only in the MS-DOS port of Emacs. windows-1252
-and windows-1251 are preloaded since the former is so common and the
-latter is used by GNU locales.

++++
+*** 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

part of a prompt is deleted, then the entire prompt must be deleted
and that all prompts must stay at the beginning of a line. If this is
not the case, then `comint-kill-region' behaves just like
-`kill-region' if read-only are involved: it copies the text to the
-kill-ring, but does not delete it.

like bash's `ESC .' binding. It is bound by default to `C-c .', but
otherwise behaves quite similarly to the bash version.
compilation processes without affecting the environment that all
subprocesses inherit.
++++
+*** New user option `compilation-disable-input'.
+If this is non-nil, send end-of-file as compilation process input.
+
+++
*** New options `next-error-highlight' and `next-error-highlight-no-select'
specify the method of highlighting of the corresponding source line
+++
*** The new command `multi-occur' is just like `occur', except it can
search multiple buffers. There is also a new command
-`multi-occur-by-filename-regexp' which allows you to specify the
-buffers to search by their filename. Internally, Occur mode has been
-rewritten, and now uses font-lock, among other changes.
+`multi-occur-in-matching-buffers' which allows you to specify the
+buffers to search by their filenames or buffer names. Internally,
+Occur mode has been rewritten, and now uses font-lock, among other
+changes.
** Grep changes:
** Xterm support:
---
-*** Emacs now responds to mouse-clicks on the mode-line, header-line and
-display margin, when run in an xterm.
+*** If you enable Xterm Mouse mode, Emacs will respond to mouse clicks
+on the mode line, header line and display margin, when run in an xterm.
---
*** Improved key bindings support when running in an xterm.

* New Modes and Packages in Emacs 22.1
+** ERC is now part of the Emacs distribution.
+
+ERC is a powerful, modular, and extensible IRC client for Emacs.
+
+To see what modules are available, type
+M-x customize-option erc-modules RET.
+
+To start an IRC session, type M-x erc-select, and follow the prompts
+for server, port, and nick.
+
+---
+** 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.
+To use this feature, turn on savehist-mode in your `.emacs' file.
+
+++
** Filesets are collections of files. You can define a fileset in
various ways, such as based on a directory tree or based on
** Calc is now part of the Emacs distribution.
Calc is an advanced desk calculator and mathematical tool written in
-Emacs Lisp. Its documentation is in a separate manual; within Emacs,
-type "C-h i m calc RET" to read that manual. A reference card is
-available in `etc/calccard.tex' and `etc/calccard.ps'.
+Emacs Lisp. The prefix for Calc has been changed to `C-x *' and Calc
+can be started with `C-x * *'. The Calc manual is separate from the
+Emacs manual; within Emacs, type "C-h i m calc RET" to read the
+manual. A reference card is available in `etc/calccard.tex' and
+`etc/calccard.ps'.

** The new package ibuffer provides a powerful, completely
In addition, when ending or calling a macro with C-x e, the macro can
be repeated immediately by typing just the `e'. You can customize
-this behavior via the variable kmacro-call-repeat-key and
+this behavior via the variables kmacro-call-repeat-key and
kmacro-call-repeat-with-arg.
Keyboard macros can now be debugged and edited interactively.
can generate a table source in typesetting and markup languages such
as latex and html from the visually laid out text table.
-+++
-** The thumbs.el package allows you to preview image files as thumbnails
-and can be invoked from a Dired buffer.
+** The tumme.el package allows you to easily view, tag and in other ways
+manipulate image files and their thumbnails, using dired as the main interface.
+Tumme provides functionality to generate simple image galleries.
+++
** Tramp is now part of the distribution.
(setq tramp-default-method "ftp")
+Removing Tramp, and re-enabling Ange-FTP, can be achieved by M-x
+tramp-unload-tramp.
+
---
** The URL package (which had been part of W3) is now part of Emacs.
---
** The TCL package tcl-mode.el was replaced by tcl.el.
This was actually done in Emacs-21.1, and was not documented.
+
+** The new package scroll-lock.el provides the Scroll Lock minor mode
+for pager-like scrolling. Keys which normally move point by line or
+paragraph will scroll the buffer by the respective amount of lines
+instead and point will be kept vertically fixed relative to window
+boundaries during scrolling.
\f
* Changes in Specialized Modes and Packages in Emacs 22.1:
+** Changes in Dired
+*** Bindings for Tumme added
+Several new keybindings, all starting with the C-t prefix, have been
+added to Dired. They are all bound to commands in Tumme. As a starting
+point, mark some image files in a dired buffer and do C-t d to display
+thumbnails of them in a separate buffer.
+** Changes in Hi Lock:
+
++++
+*** hi-lock-mode now only affects a single buffer, and a new function
+`global-hi-lock-mode' enables Hi Lock in all buffers. By default, if
+hi-lock-mode is used in what appears to be the initialization file, a
+warning message suggests to use global-hi-lock-mode instead. However,
+if the new variable `hi-lock-archaic-interface-deduce' is non-nil,
+using hi-lock-mode in an initialization file will turn on Hi Lock in all
+buffers and no warning will be issued (for compatibility with the
+behavior in older versions of Emacs).
+
+** 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 heart's 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.
+
+*** Default command prefix changed to "\C-c " (control-c space), to avoid
+intruding on user's keybinding space. Customize the
+`allout-command-prefix' variable to your preference.
+
+*** Allout now uses text overlay's `invisible' property (and others) for
+concealed text, instead of selective-display. This simplifies the code, in
+particularly avoiding the need for kludges for isearch dynamic-display,
+discretionary handling of edits of concealed text, undo concerns, etc.
+
+*** Many substantial fixes and refinements, including:
+
+ - repaired inhibition of inadvertent edits to concealed text
+ - repaired retention of topic body hanging indent upon topic depth shifts
+ - refuse to create "containment discontinuities", where a
+ topic is shifted deeper than the offspring-depth of its' container
+ - bulleting variation is simpler and more accommodating, both in the
+ default behavior and in ability to vary when creating new topics
+ - many internal fixes and refinements
+ - many module and function docstring clarifications
+ - version number incremented to 2.2
+
+** 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.
+
---
-** Makefile mode has submodes for automake, gmake, makepp and BSD make.
+** Changes to cmuscheme
+
+*** Emacs now offers to start Scheme if the user tries to
+evaluate a Scheme expression but no Scheme subprocess is running.
+
+*** If a file `.emacs_NAME' (where NAME is the name of the Scheme interpreter)
+exists in the user's home directory or in ~/.emacs.d, its
+contents are sent to the Scheme subprocess upon startup.
-The former two couldn't be differentiated before, and the latter two
+*** There are new commands to instruct the Scheme interpreter to trace
+procedure calls (`scheme-trace-procedure') and to expand syntactic forms
+(`scheme-expand-current-form'). The commands actually sent to the Scheme
+subprocess are controlled by the user options `scheme-trace-command',
+`scheme-untrace-command' and `scheme-expand-current-form'.
+
+---
+** Makefile mode has submodes for automake, gmake, makepp, BSD make and imake.
+
+The former two couldn't be differentiated before, and the latter three
are new. Font-locking is robust now and offers new customizable
faces.
*** A numeric prefix argument of `info' selects an Info buffer
with the number appended to the `*info*' buffer name (e.g. "*info*<2>").
----
++++
*** isearch in Info uses Info-search and searches through multiple nodes.
Before leaving the initial Info node isearch fails once with the error
or the default isearch search function that wraps around the current
Info node.
+---
*** New search commands: `Info-search-case-sensitively' (bound to S),
`Info-search-backward', and `Info-search-next' which repeats the last
search without prompting for a new search string.
++++
*** New command `Info-history-forward' (bound to r and new toolbar icon)
moves forward in history to the node you returned from after using
`Info-history-back' (renamed from `Info-last').
+---
*** New command `Info-history' (bound to L) displays a menu of visited nodes.
+---
*** New command `Info-toc' (bound to T) creates a node with table of contents
from the tree structure of menus of the current Info file.
++++
*** New command `info-apropos' searches the indices of the known
Info files on your system for a string, and builds a menu of the
possible matches.
+---
*** New command `Info-copy-current-node-name' (bound to w) copies
the current Info node name into the kill ring. With a zero prefix
arg, puts the node name inside the `info' function call.
----
++++
*** New face `info-xref-visited' distinguishes visited nodes from unvisited
and a new option `Info-fontify-visited-nodes' to control this.
+---
*** http and ftp links in Info are now operational: they look like cross
references and following them calls `browse-url'.
+++
** CC mode changes.
+*** The CC Mode manual has been extensively revised.
+The information about using CC Mode has been separated from the larger
+and more difficult chapters about configuration.
+
+*** Changes in Key Sequences
+**** c-toggle-auto-hungry-state is no longer bound to C-c C-t.
+
+**** c-toggle-hungry-state is no longer bound to C-c C-d.
+This binding has been taken over by c-hungry-delete-forwards.
+
+**** c-toggle-auto-state (C-c C-t) has been renamed to c-toggle-auto-newline.
+c-toggle-auto-state remains as an alias.
+
+**** The new commands c-hungry-backspace and c-hungry-delete-forwards
+have key bindings C-c C-DEL (or C-c DEL, for the benefit of TTYs) and
+C-c C-d (or C-c C-<delete> or C-c <delete>) respectively. These
+commands delete entire blocks of whitespace with a single
+key-sequence. [N.B. "DEL" is the <backspace> key.]
+
+**** The new command c-toggle-electric-mode is bound to C-c C-l.
+
+**** The new command c-subword-mode is bound to C-c C-w.
+
+*** C-c C-s (`c-show-syntactic-information') now highlights the anchor
+position(s).
+
+*** New Minor Modes
+**** Electric Minor Mode toggles the electric action of non-alphabetic keys.
+The new command c-toggle-electric-mode is bound to C-c C-l. Turning the
+mode off can be helpful for editing chaotically indented code and for
+users new to CC Mode, who sometimes find electric indentation
+disconcerting. Its current state is displayed in the mode line with an
+'l', e.g. "C/al".
+
+**** Subword Minor Mode makes Emacs recognize word boundaries at upper case
+letters in StudlyCapsIdentifiers. You enable this feature by C-c C-w. It can
+also be used in non-CC Mode buffers. :-) Contributed by Masatake YAMATO.
+
+*** New clean-ups
+
+**** `comment-close-slash'.
+With this clean-up, a block (i.e. c-style) comment can be terminated by
+typing a slash at the start of a line.
+
+**** `c-one-liner-defun'
+This clean-up compresses a short enough defun (for example, an AWK
+pattern/action pair) onto a single line. "Short enough" is configurable.
+
*** Font lock support.
CC Mode now provides font lock support for all its languages. This
supersedes the font lock patterns that have been in the core font lock
variable font-lock-maximum-decoration.
Note that the most demanding font lock level has been tuned with lazy
-fontification in mind, i.e. there should be a support mode that waits
-with the fontification until the text is actually shown
-(e.g. Just-in-time Lock mode, which is the default, or Lazy Lock
-mode). Fontifying a file with several thousand lines in one go can
-take the better part of a minute.
