** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk'
-when you run configure. This requires Gtk+ 2.0 or newer. This port
+when you run configure. This requires Gtk+ 2.4 or newer. This port
provides a way to display multilingual text in menus (with some caveats).
---
** The command line option --no-windows has been changed to
--no-window-system. The old one still works, but is deprecated.
+---
+** If the environment variable DISPLAY specifies an unreachable X display,
+Emacs will now startup as if invoked with the --no-window-system option.
+
+++
** The -f option, used from the command line to call a function,
now reads arguments for the function interactively if it is
** M-SPC (just-one-space) when given a numeric argument N
converts whitespace around point to N spaces.
+---
+** C-x 5 C-o displays a specified buffer in another frame
+but does not switch to that frame. It's the multi-frame
+analogue of C-x 4 C-o.
+
---
** New commands to operate on pairs of open and close characters:
`insert-pair', `delete-pair', `raise-sexp'.
*** In processing a local variables list, Emacs strips the prefix and
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.

-*** font-lock-lines-before specifies a number of lines before the
-current line that should be refontified when you change the buffer.
-The default value is 1.

+*** 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.
*** 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

+++
*** The commands M-x customize-face and M-x customize-face-other-window
control substitution of the file names only when they are surrounded
by whitespace. This means you can now use them as shell wildcards
too. If you want to use just plain `*' as a wildcard, type `*""'; the

special treatment in `dired-do-shell-command'.
+++
+++
*** 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:
There's a new separate package grep.el, with its own submenu and
customization group.
++++
+*** `grep-find' is now also available under the name `find-grep' where
+people knowing `find-grep-dired' would probably expect it.
+
++++
+*** New commands `lgrep' (local grep) and `rgrep' (recursive grep) are
+more user-friendly versions of `grep' and `grep-find', which prompt
+separately for the regular expression to match, the files to search,
+and the base directory for the search (rgrep only). Case sensitivitivy
+of the search is controlled by the current value of `case-fold-search'.
+
+These commands build the shell commands based on the new variables
+`grep-template' (lgrep) and `grep-find-template' (rgrep).
+
+The files to search can use aliases defined in `grep-files-aliases'.
+
+Subdirectories listed in `grep-find-ignored-directories' such as those
+typically used by various version control systems, like CVS and arch,
+are automatically skipped by `rgrep'.

-*** New option `grep-highlight-matches' highlightes matches in *grep*
+*** New option `grep-highlight-matches' highlights matches in *grep*
buffer. It uses a special feature of some grep programs which accept
--color option to output markers around matches. When going to the next
match with `next-error' the exact match is highlighted in the source
** 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.

+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.

that it's clear when part of the entered filename will be ignored due to
emacs' filename parsing rules. The ignored portion can be made dim,
-invisible, or otherwise less visually noticable. The display method can

** The URL package (which had been part of W3) is now part of Emacs.
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.
+
+** The file t-mouse.el is now part of Emacs and provides access to mouse
+events from the console. It still requires gpm to work but has been updated
+for Emacs 22. In particular, the mode-line is now position sensitive.

* Changes in Specialized Modes and Packages in Emacs 22.1:
-** Changes in Hi Lock:
+** 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
*** 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
+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.
-*** many substantial fixes and refinements, including:
+*** 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
- - 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
- - version number incremented to 2.1
+ - 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
`scheme-untrace-command' and `scheme-expand-current-form'.

are new. Font-locking is robust now and offers new customizable
faces.
Before leaving the initial Info node isearch fails once with the error
message [initial node], and with subsequent C-s/C-r continues through
other nodes. When isearch fails for the rest of the manual, it wraps
-aroung the whole manual to the top/final node. The user option
+around the whole manual to the top/final node. The user option
`Info-isearch-search' controls whether to use Info-search for isearch,
or the default isearch search function that wraps around the current
Info node.
bibtex-autokey-expand-strings control the expansion of strings when
extracting the content of a BibTeX field.
+*** The variables `bibtex-autokey-name-case-convert' and
+`bibtex-autokey-titleword-case-convert' have been renamed to
+`bibtex-autokey-name-case-convert-function' and
+`bibtex-autokey-titleword-case-convert-function'. The old names are
+still available as aliases.
+
+++
** In Enriched mode, `set-left-margin' and `set-right-margin' are now
by default bound to `C-c [' and `C-c ]' instead of the former `C-c C-l'

+GDB. You can interact with GDB through the GUD buffer in the usual way, but
there are also further buffers which control the execution and describe the
state of your program. It can separate the input/output of your program from
that of GDB and watches expressions in the speedbar. It also uses features of
Emacs 21/22 such as the toolbar, and bitmaps in the fringe to indicate
breakpoints.
-Use M-x gdb to start GDB-UI.
+To use this package just type M-x gdb. See the Emacs manual if you want the
+old behaviour.
*** The variable tooltip-gud-tips-p has been removed. GUD tooltips can now be
toggled independently of normal tooltips with the minor mode

killed.
- desktop-file-name-format. Format in which desktop file names should be saved.
- desktop-path. List of directories in which to lookup the desktop file.
The new keywords are def, newcommand, renewcommand, newenvironment and
renewenvironment.

SQL dialects. This variable can be set globally via Customize, on a
buffer-specific basis via local variable settings, or for the current
session using the new SQL->Product submenu. (This menu replaces the
the username and the pgsql `-U' option is added.

To enable this, set `calculator-output-radix' non-nil. In this mode a
separator character is used every few digits, making it easier to see
-byte boundries etc. For more info, see the documentation of the
+byte boundaries etc. For more info, see the documentation of the
variable `calculator-radix-grouping-mode'.

Previous versions of Emacs erred on the side of having a usable Emacs
through telnet, even though that was inconvenient if you use Emacs in
a local console window with a scrollback buffer. The default value of
-w32-use-full-screen-buffer is now nil, which favours local console
+w32-use-full-screen-buffer is now nil, which favors local console
windows. Recent versions of Windows telnet also work well with this
setting. If you are using an older telnet server then Emacs detects
that the console window dimensions that are reported are not sane, and
:propertize and :eval forms in the value of a variable whose
`risky-local-variable' property is nil.
+---
+The function `comint-send-input' now accepts 3 optional arguments:
+
+ (comint-send-input &optional no-newline artificial)
+
+Callers sending input not from the user should use bind the 3rd
+argument `artificial' to a non-nil value, to prevent Emacs from
+deleting the part of subprocess output that matches the input.

+*** The package-version keyword has been added to provide
+`customize-changed-options' functionality to packages in the future.
+Developers who make use of this keyword must also update the new
+variable `customize-package-emacs-version-alist'.

A file local variables list cannot specify a string with text
properties--any specified text properties are discarded.
++++
+*** The variable `enable-local-variables' controls how local variable
+lists are handled. t, the default, specifies the standard querying
+behavior. :safe means use only safe values, and ignore the rest.
+nil means ignore them all. Anything else means always query.
+
+++
*** The variable `safe-local-eval-forms' specifies a list of forms that
are ok to evaluate when they appear in an `eval' local variables
by `syntax-after').

+specifies a predicate which the file name read must satisfy. The
new variable `read-file-name-predicate' contains the predicate argument
while reading the file name from the minibuffer; the predicate in this
variable is used by read-file-name-internal to filter the completion list.
+++
** Customizable fringe bitmaps
+*** New buffer-local variables `fringe-indicator-alist' and
+`fringe-cursor-alist' maps between logical (internal) fringe indicator
+and cursor symbols and the actual fringe bitmaps to be displayed.
+This decouples the logical meaning of the fringe indicators from the
+physical appearance, as well as allowing different fringe bitmaps to
+be used in different windows showing different buffers.
+
*** New function `define-fringe-bitmap' can now be used to create new
fringe bitmaps, as well as change the built-in fringe bitmaps.
To change a built-in bitmap, do (require 'fringe) and use the symbol

markers, including the original `overlay-arrow-position' variable.
Each variable on this list can have individual `overlay-arrow-string'

relative to the left edge of the given area. Once the base offset for
a relative position has been set (by the first occurrence of one of
-these symbols), further occurences of these symbols are interpreted as
+these symbols), further occurrences of these symbols are interpreted as
the width of the area.
For example, to align to the center of the left-margin, use
(defimage foo-image '((:type xpm :file "foo/bar.xpm")))
+Note that all images formerly located in the lisp directory have been
+moved to etc/images.
+
++++
+*** New function `image-load-path-for-library' returns a suitable
+search path for images relative to library. This function is useful in
+external packages to save users from having to update
+`image-load-path'.

*** ispell4.el has been deleted. It got in the way of ispell.el and
this was hard to fix reliably. It has long been obsolete -- use
Ispell 3.1 and ispell.el.
