* Changes in Emacs 23.1
+** Completion.
+*** `completion-style' can be customized to choose your favorite completion.
+*** `completion-auto-help' can be set to `lazy' to list the completions only
+if you repeat the completion. This was already supported in
+`partial-completion-mode'.
+
** Emacs now supports using both X displays and ttys in one session.
Start the server (M-x server-start). Then `emacsclient -t' creates a
tty frame connected to the running emacs server. You can also use any
** The minor modes unify-8859-on-encoding-mode, unify-8859-on-decoding-mode
are obsolete.
+** The new commands `pp-macroexpand-expression' and `pp-macroexpand-last-sexp'
+pretty-print macro expansions.

* Startup Changes in Emacs 23.1
*** In C-x d, if you type M-n you get the visited file name of the
current buffer.
-*** In Dired, a list of commands for ! extracted from mailcap according to
-file extensions are added to the default list accessible by M-n.
+*** A list of default commands extracted from mailcap according to
+file extensions are available in the list of default values
+accessible by M-n in the minibuffer that reads a shell command
+for M-! (shell-command) and fills a list of commands for the current
+file, and in Dired for ! (dired-do-shell-command) that fills a list of
+commands for the intersection of file types of marked Dired files.
*** A list of regexp default values is available via M-n for `occur',
`keep-lines', `flush-lines' and `how-many'. This list includes the active
inter-process communication mechanism for applications residing on the
same host, based on messages. See the manual for further details.
+** zeroconf.el offers service discovery and service publishing
+interfaces according to the zeroconf specification. It communicates
+with Avahi, a zeroconf implementation, via D-Bus messages on systems
+which have installed this software.
+
** EasyPG is now part of the Emacs distribution. It is an all-in-one
GnuPG interface which includes GnuPG keyring browser, cryptographic
operations on regions and files, and automatic encryption of *.gpg
(using ps(1)). You can use the normal Emacs commands to move around in
this buffer, and special Proced commands to operate on the processes listed.
+** bug-reference.el provides clickable links to bug reports.

* Changes in Specialized Modes and Packages in Emacs 23.1
** abbrev was rewritten in Elisp and extended with more flexibility.
*** New functions: abbrev-get, abbrev-put, abbrev-table-get, abbrev-table-put,
- abbrev-table-p.
+ abbrev-table-p, abbrev-insert, abbrev-table-menu.
*** Special hook `abbrev-expand-functions' obsoletes `pre-abbrev-expand-hook'.
*** `make-abbrev-table', `define-abbrev', `define-abbrev-table' all take
extra arguments for arbitrary properties.
*** The part of an isearch that failed to match is highlighted in `isearch-fail'
face.
+*** `C-h C-h' in isearch mode displays isearch-specific Help screen,
+`C-h b' displays all isearch key bindings, `C-h k' displays the full
+documentation of the given isearch key sequence, `C-h m' displays
+documentation of isearch mode. All the rest Help commands exit isearch mode
+and execute their global definitions.
+
** smerge-refine highlights word-level details of changes in conflict.
It's used automatically as you move through conflicts, see smerge-auto-refine.
Only copyright lines with holders matching copyright-names-regexp will be
considered for update.
+** The `copyright' package looks for copyright at the end of the buffer
+if `copyright-at-end-flag' is non-nil (change-log-mode sets this).
+
** eldoc highlights the function argument under point
with the face `eldoc-highlight-function-argument'.
** VC
-*** Clicking on the VC mode-line entry now pops the VC menu.
+*** VC now supports applying VC operations to a set of files at a time.
+This enables VC to work much more effectively with changeset-oriented
+version-control systems such as Subversion, GNU Arch, Mercurial, Git
+and Bzr. VC will now pass a multiple-file commit to these systems as
+a single changeset.
-*** The VC mode-line entry now has a tooltip that explains the VC file status.
+*** vc-dir is a new command that displays file names and their VC
+status. It allows to apply various VC operations to apply a file or a
+set of files.
-*** VC now supports applying VC operations to a set of files at a time.
+*** Clicking on the VC mode-line entry now pops the VC menu.
-This enables VC to work much more effectively with changeset-oriented
-version-control systems such as Subversion, GNU Arch, Mercurial, and
-Bzr. VC will now pass a multiple-file commit to these systems

+*** The VC mode-line entry now has a tooltip that explains the VC file status.
*** In VC Annotate mode, you can type V to toggle the annotation visibility.
of the corresponding buffer as long as the asynchronous process is
active.
+*** Log entries can be modified using the key "e" in log-view.
+For now only CVS, RCS, SCCS and SVN support this functionality.
+This is done by the `modify-change-comment' backend function.
+
** log-edit now has a command bound to C-c C-d to show the diff for
the files involved.
directly still exist, for the time being, as aliases, but please start
using the new names.
+*** The function `holiday-chinese' computes holidays on the Chinese calendar.
+It has been used to add items to the list `holiday-oriental-holidays'.
+
+*** `diary-remind' accepts a negative number -DAYS as a shorthand for
+the list (1 2 ... DAYS).
+
** Miscellaneous programming mode changes
*** The file etc/emacs.py now supports both Python 2 and 3, meaning
** Miscellaneous
+*** goto-address.el provides two new minor modes, goto-address-mode and
+goto-address-prog-mode, which buttonize URLS and email addresses.
+
*** comint-mode uses `start-file-process' now (see Lisp Changes).
If `default-directory' is a remote file name, subprocesses are started
on the corresponding remote system.

* Lisp Changes in Emacs 23.1
+** `all-completions' may now return the base size in the last cdr.
+Since this means the returned list is not properly nil-terminated, this
+is an incompatible change and is thus enabled by the new variable
+completion-all-completions-with-base-size.
+
+** New function `apply-partially' for curried application.
+
+** `fill-forward-paragraph-function' specifies which function the filling
+code should use to find paragraph boundaries.
+
** The variable `this-command-keys-shift-translated' is non-nil if the
key sequence invoking the current command was found by
shift-translation.
*** The functions `modify-syntax-entry' and `modify-category-entry' now
accepts a cons of characters as the first argument, and modify all
entries in that range of characters.
++++
+*** `translation-table-for-input' is now obsolete.
** Code conversion changes
