(This change has no effect on Windows, which +uses `system-move-file-to-trash' for trashing.) + +** The pointer now becomes invisible when typing. +Customize `make-pointer-invisible' to disable this feature. + +** Font changes + +*** Emacs can use the system default monospaced font in Gnome. +To enable this feature, set `font-use-system-font' to non-nil (it is +nil by default). If the system default changes, Emacs changes also. +This feature requires Gconf support, which is automatically included +at compile-time if configure detects the gconf libraries (you can +disable this with the configure option --without-gconf). + +*** On X11, Emacs reacts to Xft changes made by configuration tools, +via the XSETTINGS mechanism. This includes antialias, hinting, +hintstyle, RGBA, DPI and lcdfilter changes. + +** Killing a buffer with a running process now asks for confirmation. +To remove this query, remove `process-kill-buffer-query-function' from +`kill-buffer-query-functions', or set the appropriate process flag +with `set-process-query-on-exit-flag'. + +** File-local variable changes + +*** Specifying a minor mode as a local variables enables that mode, +unconditionally. The previous behavior, toggling the mode, was +neither reliable nor generally desirable. + +*** There are new commands for adding and removing file-local variables: +`add-file-local-variable', `delete-file-local-variable', +`add-file-local-variable-prop-line', and +`delete-file-local-variable-prop-line'. + +*** There are new commands for adding and removing directory-local variables, +and copying them to and from file-local variable lists: +`add-dir-local-variable', `delete-dir-local-variable', +`copy-dir-locals-to-file-locals', +`copy-dir-locals-to-file-locals-prop-line' and +`copy-file-locals-to-dir-locals'. + +** Internationalization changes + +*** Unibyte sessions are now considered obsolete. +This refers to the EMACS_UNIBYTE environment variable as well as the +--unibyte, --multibyte, --no-multibyte, and --no-unibyte command line +arguments. Customizing enable-multibyte-characters and setting +default-enable-multibyte-characters are also deprecated. + +*** New coding system `utf-8-hfs'. +This is suitable for default-file-name-coding-system on Mac OS X; see +international/ucs-normalize.el. + +** Function arguments in *Help* buffers are now shown in upper-case. +Customize `help-downcase-arguments' to t to show them in lower-case. + +** New command `async-shell-command', bound globally to `M-&'. +This executes the command asynchronously, similar to calling `M-!' and +manually adding an ampersand to the end of the command. With `M-&', +you don't need the ampersand. The output appears in the buffer +`*Async Shell Command*'. + +** When running in a new enough xterm (newer than version 242), Emacs +asks xterm what the background color is and it sets up faces +accordingly for a dark background if needed (the current default is to +consider the background light). + + +* Editing Changes in Emacs 23.2 + +** Kill-ring and selection changes + +*** If `select-active-regions' is t, any active region automatically +becomes the primary selection (for interaction with other window +applications). If you enable this, you might want to bind +`mouse-yank-primary' to Mouse-2. + +*** When `save-interprogram-paste-before-kill' is non-nil, the kill +commands save the interprogram-paste selection into the kill ring +before doing anything else. This avoids losing the selection. + +*** When `kill-do-not-save-duplicates' is non-nil, identical +subsequent kills are not duplicated in the `kill-ring'. + +** Completion changes + +*** The new command `completion-at-point' provides mode-sensitive completion. + +*** tab-always-indent set to `complete' lets TAB do completion as well. + +*** The new completion-style `initials' is available. +For instance, this can complete M-x lch to list-command-history. + +*** The new variable `completions-format' determines how completions +are displayed in the *Completions* buffer. If you set it to +`vertical', completions are sorted vertically in columns. + +** The default value of `blink-matching-paren-distance' is increased. + +** M-n provides more default values in the minibuffer for commands +that read file names. These include the file name at point (when ffap +is loaded without ffap-bindings), the file name on the current line +(in Dired buffers), and the directory names of adjacent Dired windows +(for Dired commands that operate on several directories, such as copy, +rename, or diff). + +** M-r is bound to the new `move-to-window-line-top-bottom'. +This moves point to the window center, top and bottom on successive +invocations, in the same spirit as the C-l (recenter-top-bottom) +command. + +** The new variable `recenter-positions' determines the default +cycling order of C-l (`recenter-top-bottom'). + +** The abbrevs file is now a file named abbrev_defs in +user-emacs-directory; but the old location, ~/.abbrev_defs, is used if +that file exists. + + +* Changes in Specialized Modes and Packages in Emacs 23.2 + +** The bookmark menu has a narrowing search via bookmark-bmenu-search. + +** Calc + +*** The Calc settings file is now a file named calc.el in +user-emacs-directory; but the old location, ~/.calc.el, is used if +that file exists. + +*** Graphing commands (`g f' etc.) now work on MS-Windows, if you have +the native Windows port of Gnuplot version 3.8 or later installed. + +** Calendar and diary + +*** Fancy diary display is now the default. +If you prefer the simple display, customize `diary-display-function'. + +*** The diary's fancy display now enables view-mode. + +*** The command `calendar-current-date' accepts an optional argument +giving an offset from today. + +** Desktop + +*** The default value for `desktop-buffers-not-to-save' is nil. +This means Desktop will try restoring all buffers, when you restart +your Emacs session. Also, `desktop-buffers-not-to-save' is only +effective for buffers that have no associated file. If you want to +exempt buffers that do correspond to files, customize the value of +`desktop-files-not-to-save' instead. + +** Dired + +*** The new variable `dired-auto-revert-buffer', if non-nil, causes +Dired buffers to be reverted automatically on revisiting them. + +** DocView + +*** When `doc-view-continuous' is non-nil, scrolling a line +on the page edge advances to the next/previous page. + +** Elint + +*** Elint now uses compilation-mode. + +*** Elint can now scan individual files and whole directories, +and can be run in batch mode. + +*** Elint does a more thorough initialization, and recognizes more built-in +functions and variables. Customize `elint-scan-preloaded' if you want +to sacrifice some accuracy for a faster startup. + +*** Elint attempts some basic understanding of featurep and (f)boundp tests. + +*** Customize `elint-ignored-warnings' to suppress some warnings. + +** GDB-UI + +*** Toolbar functionality for reverse debugging. Display of STL +collections as watch expressions. These features require GDB 7.0 or later. + +** Grep + +*** A new command `zrgrep' searches recursively in gzipped files. + +** Info + +*** The new command `Info-virtual-index' bound to "I" displays a menu of +matched topics found in the index. + +*** The new command `info-finder' replaces finder.el with a virtual Info +manual that generates an Info file which gives the same information +through a menu structure. + +** LaTeX mode now provides completion (via completion-at-point). + +** Message mode is now the default mode for composing mail. + +The default for `mail-user-agent' is now message-user-agent, so the +C-x m (`compose-mail') command uses Message mode instead of Mail mode. + +Message mode has been included in Emacs, as part of the Gnus package, +for several years. It provides several features that are absent in +Mail mode, such as MIME handling. + +*** If the user has not customized mail-user-agent, `compose-mail' +checks for Mail mode customizations, and issues a warning if these +customizations are found. This alerts users who may otherwise be +unaware that their mail configuration has changed. + +To disable this check, set compose-mail-user-agent-warnings to nil. + +** The default value of mail-interactive is t, since Emacs 23.1. +(This was not announced at the time.) It means that when sending mail, +Emacs will wait for the process sending mail to return. If you +experience delays when sending mail, you may wish to set this to nil. + +** nXML mode is now the default for editing XML files. + +** pcomplete provides a new command `pcomplete-std-completion' which +is similar to `pcomplete' but using the standard completion UI code. + +** Shell (and other comint modes) + +*** M-s is no longer bound to `comint-next-matching-input'. + +*** M-r is now bound to `comint-history-isearch-backward-regexp'. +This starts an incremental search of the comint/shell input history. + +*** ansi-color is now enabled by default in Shell mode. +To disable it, set ansi-color-for-comint-mode to nil. + +** Tramp + +*** New connection methods "rsyncc", "imap" and "imaps". +On systems which support GVFS-Fuse, Tramp offers also the new +connection methods "dav", "davs", "obex" and "synce". + +** VC and related modes + +*** When using C-x v v or C-x v i on a unregistered file that is in a +directory not controlled by any VCS, ask the user what VC backend to +use to create a repository, create a new repository and register the +file. + +*** New command `vc-root-print-log', bound to `C-x v L'. +This displays a `*vc-change-log*' buffer showing the history of the +version-controlled directory tree as a whole. + +*** New command `vc-root-diff', bound to `C-x v D'. +This is similar to `vc-diff', but compares the entire directory tree +of the current VC directory with its working revision. + +*** `C-x v l' and `C-x v L' do not show the full log by default. +The number of entries shown can be chosen interactively with a prefix +argument, or by customizing vc-log-show-limit. The `*vc-change-log*' +buffer now contains buttons at the end of the buffer, which can be +used to increase the number of entries shown. RCS, SCCS, and CVS do +not support this feature. + +*** vc-annotate supports annotations through file copies and renames, +it displays the old names for the files and it can show logs/diffs for +the corresponding lines. Currently only Git and Mercurial take +advantage of this feature. + +*** The log command in vc-annotate can display a single log entry +instead of redisplaying the full log. The RCS, CVS and SCCS VC +backends do not support this. + +*** When a file is not found, VC will not try to check it out of RCS anymore. + +*** Diff and log operations can be used from Dired buffers. + +*** vc-git changes + +**** The short log format for git makes use of the graph display, +so it's not supported on git versions earlier than 1.5.6. + +**** vc-dir uses the --relative option of git, and so requires at least +git version 1.5.5. + +**** Support for operating with stashes has been added to vc-dir: +the stash list is displayed in the *vc-dir* header, stashes can be +created, removed, applied and their content displayed. + +*** vc-bzr supports operating with shelves: the shelve list is +displayed in the *vc-dir* header, shelves can be created, removed and applied. + +*** log-edit-strip-single-file-name controls whether or not single filenames +are stripped when copying text from the ChangeLog to the *VC-Log* buffer. + +** Miscellaneous + +*** Interactively `multi-isearch-buffers' and `multi-isearch-buffers-regexp' +read buffer names to search, one by one, ended with RET. With a prefix +argument, they ask for a regexp, and search in buffers whose names match +the specified regexp. Interactively `multi-isearch-files' and +`multi-isearch-files-regexp' read file names to search, one by one, +ended with RET. With a prefix argument, they ask for a wildcard, and +search in file buffers whose file names match the specified wildcard. + +*** Autorevert Tail mode now works also for remote files. + +*** The new eshell built-in commands `su' and `sudo' support Tramp. +Thus, they change `default-directory' to reflect the new user id, and +let commands run under that user's permissions. This works even when +`default-directory' is already remote. Calling the external commands +is possible via `*su' or `*sudo', respectively. + +** Obsolete packages + +*** sym-comp.el is now obsolete, superseded by completion-at-point. + +*** lucid.el and levents.el are now obsolete. + + +* New Modes and Packages in Emacs 23.2 + +** CEDET (the Collection of Emacs Development Tools) is now in Emacs. +This is a collection of packages to aid with using Emacs as an IDE +(integrated development environment): + +*** The Semantic package allows the use of parsers to intelligently +edit and navigate source code. Parsers for C/C++, Java, Javascript, +and several other languages are included by default, and Semantic can +also interface with external tools such as GNU Global and GNU Idutils. + +To enable Semantic, use the global minor mode `semantic-mode'. +See the Semantic manual for details. + +*** EDE (Emacs Development Environment) is a package for managing code +projects, including features such as automatic Makefile generation. + +To enable EDE, use the minor mode `global-ede-mode'. +See the EDE manual for details. + +*** SRecode is a library for recoding Semantic tags back into source +code. It is currently used by some parts of Semantic and EDE; in the +future, it may be used for code generation features. + +*** The EIEIO library implements a subset of the Common Lisp Object +System (CLOS). It is used by the other CEDET packages. + +** mpc.el is a front end for the Music Player Daemon. Run it with M-x mpc. + +** htmlfontify.el turns a fontified Emacs buffer into an HTML page. + +** js.el is a new major mode for JavaScript files. + +** imap-hash.el is a new library to address IMAP mailboxes as hashtables. + + +* Incompatible Lisp Changes in Emacs 23.2 + +** The Lisp reader turns integers that are too large/small into floats. +For instance, on machines where `536870911' is the largest integer, +reading `536870912' gives the floating-point object `536870912.0'. + +This change only concerns the Lisp reader; it does not affect how +actual integer objects overflow. + +** Several obsolete functions removed. +The functions have been obsolete since Emacs 19, and are unlikely to +be in use: + + time-stamp-month-dd-yyyy, time-stamp-dd/mm/yyyy, time-stamp-mon-dd-yyyy + time-stamp-dd-mon-yy, time-stamp-yy/mm/dd, time-stamp-yyyy/mm/dd, + time-stamp-yyyy-mm-dd, time-stamp-yymmdd, time-stamp-hh:mm:ss, + time-stamp-hhmm, baud-rate + +** Support for generating Emacs 18 compatible bytecode (by setting +the variable `byte-compile-compatibility') has been removed. + +** In image-mode.el `image-mode-maybe' is obsolete. +Instead, you can either use `image-mode' (which displays an image file +as the actual image initially), or `image-mode-as-text' (when you want +to display an image file as text initially). `image-mode-as-text' is a +combination of a non-image mode from `auto-mode-alist' (or Fundamental +mode) and `image-minor-mode'. `image-minor-mode' provides a `C-c C-c' +key binding to toggle image display. +`image-toggle-display-text' removes image properties. +`image-toggle-display-image' adds image properties. +`image-toggle-display' toggles between `image-mode-as-text' and `image-mode'. + + +* Lisp changes in Emacs 23.2 + +** All the default-FOO variables that hold the default value of the FOO +variable, are now declared obsolete. + +** read-key is a function halfway between read-event and read-key-sequence. +It reads a single key, but obeys input and escape sequence decoding. + +** Frame parameter changes + +*** You can give the `fullscreen' frame parameter the value `maximized'. +This maximizes the frame. + +*** The new frame parameter `sticky' makes Emacs frames sticky in +virtual desktops. + +** Completion changes + +*** completion-base-size is obsoleted by completion-base-position. +This change causes a few backward incompatibilities, mostly with +choose-completion-string-functions where the `mini-p' argument has +been replaced by a `base-position' argument, and where the `base-size' +argument is now always nil. + +*** New function `completion-in-region' to use the standard completion +facilities on a particular region of text. + +*** The 4th arg to all-completions (aka hide-spaces) is declared obsolete. + +*** completion-annotate-function specifies how to compute annotations +for completions displayed in *Completions*. + +** Minibuffer changes + +*** read-file-name-predicate is obsolete. It was used to pass the predicate +to read-file-name-internal because read-file-name-internal abused its `pred' +argument to pass the current directory, but this hack is not needed +any more. + +** Changes to file-manipulation functions + +*** `delete-directory' has an optional parameter RECURSIVE. + +*** New function `copy-directory', which copies a directory recursively. + +** called-interactively-p now takes one argument and replaces interactive-p +which is now marked obsolete. + +** New function set-advertised-calling-convention makes it possible +to obsolete arguments as well as make some arguments mandatory. + +** You can control which binding is preferentially shown in menus and +docstrings by adding a `:advertised-binding' property to the corresponding +command's symbol. That property can hold a single binding or a list +of bindings. + +** Network and process changes + +*** start-process-shell-command and start-file-process-shell-command +now only take a single `command' argument. + +*** The new variable `process-file-side-effects' should be set to nil +if a `process-file' call does not change a remote file. This allows +file name handlers such as Tramp to optimizations. + +*** make-network-process can now also create `seqpacket' Unix sockets. + +** Loading changes + +*** eval-next-after-load is obsolete. + +*** New hook `after-load-functions' run after loading an Elisp file. + +** Byte compilation changes + +*** Changing the file-names generated by byte-compilation by redefining +the function `byte-compile-dest-file' before loading bytecomp.el is obsolete. +Instead, customize byte-compile-dest-file-function. + +*** `byte-compile-warnings' has new members, `constants' and `suspicious'. + +** New macro with-silent-modifications to tweak text properties without +affecting the buffer's modification state. + +** Hash tables have a new printed representation that is readable. +The feature `hashtable-print-readable' identifies this new +functionality. + +** New functions for performing Unicode normalization: +ucs-normalize-NFD-region, ucs-normalize-NFD-string, +ucs-normalize-NFC-region, ucs-normalize-NFC-string, +ucs-normalize-NFKD-region, ucs-normalize-NFKD-string, +ucs-normalize-NFKC-region, ucs-normalize-NFKC-string, +ucs-normalize-HFS-NFD-region, ucs-normalize-HFS-NFD-string, +ucs-normalize-HFS-NFC-region, ucs-normalize-HFS-NFC-string. + +** Face aliases can now be marked as obsolete, using the macro +`define-obsolete-face-alias'. + +** New function `window-full-height-p', analogous to the full-width version. + + +* Changes in Emacs 23.2 on non-free operating systems + +** On MS-Windows, `display-time' now displays the system load average +as well as the time, as it does on GNU and Unix. + + +* Installation Changes in Emacs 23.1 + +** The default X toolkit is now Gtk+, rather than Lucid. +The configure option `--with-gtk' has been removed. Gtk is now the +default toolkit, but you can use --with-x-toolkit=gtk if necessary. + +** New font code. +Fonts are handled by new code capable of dealing with multiple font +backends. This uses the freetype and fontconfig libraries. + +*** Emacs now accepts font names supplied in the fontconfig format +(e.g. "monospace-12:bold") and GTK format (e.g. "Monospace Bold 12"). + +*** Added support for local fonts (fonts installed on the machine +where Emacs is running). + +*** Added support for the Xft library for antialiasing. + +*** Added support for the otf library for complex text layout by +OpenType fonts. + +*** Added support for the m17n library for text shaping. + +** Changes to image support + +*** configure now checks for libgif before libungif when searching for +a GIF library. + +*** Emacs now supports the SVG image format through librsvg2. + +*** Emacs now supports multi-page TIFF images. + +** New NeXTSTEP-based port. +This provides support for GNUstep (via the GNUstep libraries) and Mac +OS X (via the Cocoa libraries). + +Specify --with-ns to configure for this. By default, a self-contained +app will be built (containing all lisp). To install/share lisp with +other emacsen (e.g. X11 build) use --disable-ns-self-contained. See +nextstep/README and nextstep/INSTALL in the Emacs source directory. + +** Mac OS X is no longer supported via Carbon. +Use the NeXTSTEP port, described above. + +** The new configuration option "--with-dbus" enables D-Bus language +bindings for Emacs. + +** Support for many obsolete platforms has been removed. +See the list at the end of etc/MACHINES for details. + +*** Support for systems without alloca has been removed. + +*** Support for Sun windows has been removed. + +*** The `emacstool' utility has been removed. + +** The following platforms will be removed in a future Emacs version: +If you are still using Emacs on one of these platforms, please email +emacs-devel@gnu.org to inform the Emacs developers. + +*** Old GNU/Linux systems based on libc version 5. + +*** Old FreeBSD, NetBSD, and OpenBSD systems based on the COFF +executable format. + +*** Solaris versions 2.6 and below. + +*** Solaris on IBM RS6000 machines. + +*** UNIX System V (the original SysV, not later platforms based on it). + +*** Unixware on non-x86 machines. + +*** Platforms not supporting shared libraries (i.e., requiring the +NO_SHARED_LIBS compilation flag). + +** The configure options `--with-gcc', `--without-gcc' have been removed. +Configure will use gcc by default. Set the CC environment variable if +you need control over which C compiler is used. + +** The refcards are now shipped as PDF files. + +** The manuals are now licensed under the GNU Free Documentation License v1.3, +or any later version. + +** Emacs 23 comes with a new set of default icons. +Various resolutions are available as etc/images/icons/hicolor/*/apps/emacs.png. +The Emacs 22 icon is available as `emacs22.png' in the same location. + +* Changes in Emacs 23.1 + +** Improved X Window System support + +*** Emacs now supports using both X displays and ttys in one session. +With an Emacs server active (M-x server-start), `emacsclient -t' +creates a tty frame connected to the running emacs server. You can +use any number of different ttys. `emacsclient -c' creates a new X11 +frame on the current $DISPLAY (or a tty frame if $DISPLAY is not set). +There may be problems if a display exits unexpectedly and Emacs is compiled +with Gtk+, see etc/PROBLEMS. + +You can test for the presence of this feature in your Lisp code by +testing for the `multi-tty' feature. + +*** Emacs starts in the background, as a daemon, when given the +--daemon command line argument. It disconnects from the terminal and +starts the server. Clients can connect and create graphical or +terminal frames using emacsclient. + +**** emacsclient starts emacs in daemon mode and connects to it when +--alternate-editor="" is used (or when the evironment variable +ALTERNATE_EDITOR is set to "") and emacsclient cannot connect to an +emacs server. + +*** The new command close-display-connection closes a connection to a +remote display. There are some bugs for Gtk+. See etc/PROBLEMS. + +*** Emacs now supports the XEmbed specification. +You can embed Emacs in another application on X11. The new command line +option --parent-id is used to pass the parent window id to Emacs. See +http://standards.freedesktop.org/xembed-spec/xembed-spec-latest.html +for details about XEmbed. + +*** Emacs can now set the frame opacity. +The opacity of a frame can be controlled by setting the `alpha' frame +parameter. This only takes effect on a compositing window manager for +the X Window System, such as Compiz, Beryl and Compiz Fusion, on Mac +OS X, or on Windows 2000 and later versions of Windows. + +The alpha parameter should be an integer between 0 (transparent) and +100 (opaque), or a float number between 0.0 and 1.0. It can also be a +cons cell (ACTIVE . INACTIVE), where ACTIVE is the opacity of an +active frame and INACTIVE is the opacity of non-active frames. + +The variable `frame-alpha-lower-limit' defines a lower bound for the +opacity; the default is 20. + +** Internationalization changes + +*** 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' (`emacs-internal' is an alias +for this). This encoding is backward-compatible with Unicode's UTF-8 +encoding. The internal encoding previously used by Emacs, +`emacs-mule', is still available for reading and writing files. + +During byte-compilation, Emacs 23 uses `utf-8-emacs' to write files. +As a result, byte-compiled files containing non-ASCII characters 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). This takes somewhat more time, so it +may be worth recompiling existing .elc files which don't need to be +shared with older Emacsen. + +*** There are new coding systems/aliases; see M-x list-coding-systems. + +*** There is a new charset implementation with many new charsets. +See M-x list-character-sets. New charsets can be defined conveniently +as tables of unicodes. + +*** There are new language environments for Chinese-GBK, +Chinese-GB18030, Khmer, Bengali, Punjabi, Gujarati, Oriya, Telugu, +Sinhala, and TaiViet. + +*** The minor modes unify-8859-on-encoding-mode and +unify-8859-on-decoding-mode are obsolete. + +*** `ucs-insert' is bound to `C-x 8 RET' and in addition to hex numbers +accepts numbers in hash notation (e.g. #o21430 for octal, or #10r8984 for +decimal). It also accepts Unicode character names with completion. + +*** The `cyrillic-translit' input method supports many new characters. +Common typographical characters available from Unicode were added to +`cyrillic-translit': punctuation marks, accented characters, fractions, +and others. + +** Emacs now supports serial port access on GNU/Linux, Unix, and +Windows. The new command `serial-term' starts an interactive terminal +on a serial port. The serial port can be configured at runtime with +the mode-line mouse menu. + +** Menu Bar changes + +*** In the Options menu, the "Set Default Font" item applies the +selected font to the `default' face on all frames, not just the +current frame. Furthermore, if Emacs is compiled with both GTK and +Fontconfig support, the "Set Default Font" item uses the GTK font +selection dialog instead of an Emacs pop-up menu. + +*** The font setting chosen by "Set Default Font" is saved if the +"Save Options" item is used. + +*** The Tools menu contains a new Encryption/Decryption submenu. +This contains commands provided by EasyPG, the newly-included +interface to GnuPG (see New Modes and Packages). + +*** In the Options menu, the "Truncate Long Lines in the Buffer" entry +has been replaced with a submenu offering three different ways to +handle long lines: truncation, continuation at the window edge, and +the new word wrapping behavior (see Editing Changes, below). + +*** Improvements to menus for major and minor modes +More major and minor modes now have a mode specific menu, and existing +mode menus have been improved to include more functionality. + +** Mode-line changes + +*** The mode-line displays a `@', instead of `-', if the +default-directory for the current buffer is on a remote machine. + +*** The mode-line displays a mode menu when mouse-1 is clicked on a +minor mode, in the same way as it already did for major modes. + +*** The `mode-line-emphasis' face is used to highlight certain +mode-line information (e.g. waiting for a VC command to finish). + +*** The mode-line tooltips have been improved to provide more details. + +*** The VC, line/colum number and minor mode indicators on the mode +line are now interactive: mouse-1 can be used on them to pop up a menu. + +** File deletion can make use of the Recycle Bin or system Trash folder. +Set `delete-by-moving-to-trash' non-nil to use this. Deleted files +and directories will then be sent to the Recycle Bin on Windows, and +to `trash-directory' on other systems. + +** Directory-local variables can now be defined. +By default, Emacs looks in .dir-locals.el for directory-local +variables. For more information, see `dir-locals-set-directory-class' +and `dir-locals-set-class-variables'. + +** Emacs can now use `auth-source' for authentication. +`smtpmail' and `url' (Tramp and Gnus also) use `auth-source' to obtain +login names and passwords. The match, if found, is reported +in *Messages* with the password blanked out. + +** `where-is-preferred-modifier' can specify your favorite modifier. + + +* Startup Changes in Emacs 23.1 + +** The option `inhibit-startup-screen' (with aliases to old names +`inhibit-splash-screen' and `inhibit-startup-message') doesn't inhibit +display of the initial message in the *scratch* buffer. If you don't +want to display the initial message in the *scratch* buffer at startup, +you can set the option `initial-scratch-message' to nil. + +** New user option `initial-buffer-choice' specifies what to display +after starting Emacs: startup screen, *scratch* buffer, visiting a +file or directory. + +** New alias `argv' for `command-line-args-left' +This is a convenience alias, so that one can write `(pop argv)' +inside of --eval command line arguments in order to access +following arguments. + +** The abbrev file is no longer read at startup in batch mode. + +** Emacs now supports invocation by an X session manager. +It can save a session and restore it later. See the documentation of +the functions `emacs-session-save' and `emacs-session-restore'. +(Actually, this feature was introduced with Emacs 22, but it was not +documented.) + +* Incompatible Editing Changes in Emacs 23.1 + +** In Dired, `dired-flag-garbage-files' is rebound from `&' to `%&' +on the regexp command prefix map. + +** In Dired-x, all command guesses for ! are now added to the default +list accessible by M-n instead of pushing all guesses temporarily into +the history list. + +** In Isearch mode, a special case of typing `C-w' at the beginning of +the minibuffer that toggles word search (i.e. using key sequences +`C-s RET C-w' or `C-s M-e C-w') is obsolete. You can use the global key +`M-s w' to start word search, or type `M-s w' in Isearch mode to +toggle word search. To start nonincremental word search you can now use +`M-s w RET' and `M-s w C-r RET' instead of `C-s RET C-w' and `C-r RET C-w'. + +** In Info, `Info-search' is unbound from `M-s' to allow using `M-s w' +for word search as well as other search commands from the global prefix +key `M-s'. `Info-search' is still bound to `s', and also incremental +search commands `C-s', `C-M-s', `C-r', `C-M-r' are available for searching +through multiple Info nodes, together with their nonincremental versions +`C-s RET', `C-r RET', `C-M-s RET', `C-M-r RET', `M-s w RET'. + +** In Text mode, `center-line' and `center-paragraph' are rebound from +`M-s' and `M-S' to global keys `M-o M-s' and `M-o M-S' on the global +prefix map `M-o', which is intended for such formatting commands. + +** 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. + + +* Editing Changes in Emacs 23.1 + +** The C-n and C-p line-motion commands now move by screen lines, +taking continued lines and variable-width characters into account. +Setting `line-move-visual' to nil reverts this to the previous +behavior (i.e., motion by logical lines based on buffer contents +alone). + +** C-x C-c now invokes `save-buffers-kill-terminal', and C-z now +invokes `suspend-frame'. These changes are for compatibility with the +new multi-tty support (see `Improved X Window System support' above). + +** Mark changes + +*** Transient Mark mode is now on by default. + +*** mark-even-if-inactive now defaults to t + +*** When Transient Mark mode is on, C-SPC C-SPC pushes a mark without +activating it. + +*** When Transient Mark mode is on, M-q now fills the region if the +region is active. Otherwise, it fills the current paragraph. + +*** When Transient Mark mode is on, M-$ now checks spelling of the +region if the region is active. Otherwise, it checks spelling of the +word at point. + +*** When Transient Mark mode is on, TAB now indents the region if the +region is active. + +*** The variable `use-empty-active-region' controls whether an empty +active region in Transient Mark mode should make commands operate on +that empty region. + +** Temporarily active regions + +*** The new variable shift-select-mode, non-nil by default, controls +shift-selection. When Shift Select mode is on, shift-translated +motion keys (e.g. S-left and S-down) activate and extend a temporary +region, similar to mouse-selection. + +*** Temporarily active regions, created using shift-selection or +mouse-selection, are not necessarily deactivated in the next command. +They are only deactivated after point motion commands that are not +shift-translated, or after commands that would ordinarily deactivate +the mark in Transient Mark mode (e.g., any command that modifies the +buffer). + +** Minibuffer and completion changes + +*** Emacs may ask for confirmation before opening a non-existent file +or buffer. By default, Emacs requests confirmation if you type RET +immediately after TAB, and the resulting input is not an existing file +or buffer; this usually happens when the minibuffer input did not +complete far enough and you entered RET by mistake. In that case, +Emacs puts the message "[Confirm]" in the minibuffer; type RET again +to create the file or buffer. + +The new variable confirm-nonexistent-file-or-buffer determines whether +Emacs asks for confirmation. The default value is `after-completion'. +If you change it to t, Emacs always asks for confirmation; if you +change it to nil, Emacs never asks for confirmation. + +*** The rules for performing completion have been changed. +When generating completion alternatives, Emacs now takes the +minibuffer text after point, if any, into account: this text is +treated as a substring of the remaining part of the completion +alternative (i.e., the part not matched by the minibuffer text before +point). If no completion alternatives are found this way, Emacs +attempts to perform partial-completion. If still no completion +alternatives are found, we fall back on the Emacs 22 rules for +performing completion. + +The new variable `completion-styles' can be customized to choose your +favorite completion style. + +*** When M-n in the minibuffer reaches the end of the list of defaults, +it adds the completion list to the end, so next M-n continues putting +completion items to the minibuffer. The same principle applies to +incremental search commands as well: C-s or C-M-s starts searching +the default values and after the end of defaults they continue +searching minibuffer completion items. + +*** Minibuffer input of shell commands now comes with completion. + +*** In the `C-x d' (Dired) prompt, typing M-n gives the visited file +name of the current buffer. + +*** In the M-! (shell-command) prompt, M-n provides some default commands. +These are guessed using the file extension of the current file, based +on the file-handlers specified in the operating system's `mailcap' +file. The ! command in Dired (dired-do-shell-command) works +similarly, using the file displayed on the current line. + +*** 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 +region in transient-mark-mode, the word under the cursor, the last Isearch +regexp, the last Isearch string and the last replacement regexp. + +*** When enable-recursive-minibuffers is non-nil, operations which use +switch-to-buffer (such as C-x b and C-x C-f) do not fail any more when +used in a minibuffer or a dedicated window. Instead, they fallback on +using pop-to-buffer, which will use some other window. This change +has no effect when enable-recursive-minibuffers is nil (the default). + +*** Isearch started in the minibuffer searches in the minibuffer history. +Reverse Isearch commands (C-r, C-M-r) search in previous minibuffer +history elements, and forward Isearch commands (C-s, C-M-s) search in +next history elements. When the reverse search reaches the first history +element, it wraps to the last history element, and the forward search +wraps to the first history element. When the search is terminated, the +history element containing the search string becomes the current. + +*** The variable read-file-name-completion-ignore-case overrides +completion-ignore-case for file name completion. + +*** The variable read-buffer-completion-ignore-case overrides +completion-ignore-case for buffer name completion. + +*** The new command `minibuffer-force-complete' chooses one of the +possible completions, rather than stopping at the common prefix. + +*** If `completion-auto-help' is `lazy', Emacs shows the completions +buffer only on the second attempt to complete. This was already +supported in `partial-completion-mode'. + +** Face changes + +*** S-down-mouse-1 now pops up a menu for changing the font and text +size of the default face in the current buffer. The face is changed +via face remapping (see Lisp changes, below). + +*** New commands to change the default face size in the current buffer. +To increase it, type `C-x C-+' or `C-x C-='. To decrease it, type +`C-x C--'. To restore the default (global) face size, type `C-x C-0'. +These work via Text Scale mode, a new minor mode. + +The final key in the above commands may be repeated without the +leading `C-x', e.g. `C-x C-= C-= C-=' increases the face height by +three steps. Each step scales the height of the default face by the +value of the variable `text-scale-mode-step'. + +*** The commands buffer-face-mode and buffer-face-set can be used to +remap the default face in the current buffer. See "Buffer Face mode", +under New Modes and Packages. + +** Primary selection changes + +*** You can disable kill ring commands from accessing the primary +selection by setting `x-select-enable-primary' to nil. + +** Continuation lines can now be wrapped at word boundaries +(word-wrapping). This is controlled by the new per-buffer variable +`word-wrap'. Word wrapping does not take place if continuation lines +are not shown, e.g. if truncate-lines is non-nil. The most convenient +way to enable word-wrapping is using the new minor mode Visual Line +mode; in addition to setting `word-wrap' to t, this rebinds some +editing commands to work on screen lines rather than text lines. See +New Modes and Packages, below. + +** Window management changes + +*** truncate-partial-width-windows now accepts integer values, which +specify a minimum window width for partial-width windows, below which +lines are truncated. The default has been changed to 50. + +*** The new command balance-windows-area balances windows both +vertically and horizontally. + +*** pop-to-buffer now always sets input focus when the popped-to window +is on a different frame. + +** Miscellaneous changes: + +*** C-l is bound to the new command recenter-top-bottom, rather than recenter. +This moves the current line to window center, top and bottom on +successive invocations. + +*** scroll-preserve-screen-position also preserves the column position. + +*** If `yank-pop-change-selection' is t, rotating the kill ring also +updates the selection or clipboard to the current yank, just as M-w +would do so with the text it copies to the kill ring. + +*** C-M-% now shows replacement as it would look in the buffer, with +`\N' and `\&' substituted according to the match. Old behavior can be +restored by customizing `query-replace-show-replacement'. + +*** The command shell prompts for the default directory, when it is +called with a prefix and the default directory is a remote file name. +This is because some file name handlers (like ange-ftp) are not able to +run processes remotely. + +*** The new command kill-matching-buffers kills buffers whose name +matches a regexp. + +*** The value of comment-style now defaults to `indent'. +Thefore, comment-start markers are inserted at the current indentation +of the region to comment, rather than the leftmost column. + +*** The new commands `pp-macroexpand-expression' and +`pp-macroexpand-last-sexp' pretty-print macro expansions. + +*** The new command `set-file-modes' allows to set file's mode bits. +The mode bits can be specified in symbolic notation, like with GNU +Coreutils, in addition to an octal number. `chmod' is a new +convenience alias for this function. + +*** `next-error-recenter' specifies how next-error should recenter the +visited source file. Its value can be a number (for example, 0 for +top line, -1 for bottom line), or nil for no recentering. + +*** When typing in a password in the echo area, C-y yanks the current +kill into the password. + +*** Tooltip frame parameters `font' and `color' in `tooltip-frame-parameters' +are ignored. Customize the `tooltip' face instead. + +*** `mkdir' is a new convenience alias for `make-directory'. + +* New Modes and Packages in Emacs 23.1 + +** Auto Composition Mode is a minor mode that composes characters +automatically when they are displayed. It is globally on by default. +It uses `auto-composition-function' (default `auto-compose-chars'). + +** Bubbles, a new game, is similar to SameGame. + +** Buffer Face mode is a minor mode for remapping the default face in +the current buffer. The variable `buffer-face-mode-face' specifies +the face to remap to. The command `buffer-face-set' prompts for a +face name, sets `buffer-face-mode-face' to it, and enables +buffer-face-mode. See "Face changes", under Editing Changes, for a +description of face remapping. + +** butterfly flips the desired bit on the drive platter. +See http://xkcd.com/378/ + +** bug-reference.el provides clickable links to bug reports. + +** dbus.el provides D-Bus language bindings. +D-Bus is an inter-process communication mechanism for applications +residing on the same host. See the manual for details. + +** DocView mode allows viewing of PDF, PostScript and DVI documents. +One can also search for a regular expression in the document. For +details, see the commentary in doc-view.el. + +PDF and DVI files are now opened in Doc View mode by default. + +In Postcript mode, C-c C-c launches Doc View minor mode for viewing +the postscript file. + +** EasyPG provides an interface to the GNU Privacy Guard (GnuPG). +It includes a GnuPG keyring browser, cryptographic operations on +regions and files, and automatic encryption of *.gpg files. For +details, see the EasyPG Assistant User's Manual. + +** json.el is a library for parsing and generating JSON +(JavaScript Object Notation), a lightweight data-interchange format. + +** linum.el is a new minor mode to display line numbers for the +current buffer. + +** mairix.el is an interface to mairix, a free tool for indexing and +searching locally stored mail. It allows you to query mairix and +display the search results with Rmail, Gnus and VM. Note that there +is an existing Gnus back end, nnmairix.el, which should be used with +Maildir/MH setups. + +** minibuffer-depth-indicate-mode shows the minibuffer depth in the prompt. + +** nXML Mode +This is a new mode for editing XML documents. It allows a schema to +be associated with the XML document being edited, using Relax NG as +the schema language. The schema is used to provide two key features: + +*** Continuous validation. nXML validates as you type, highlighting +any invalid parts of your document. + +*** Completion. nXML can assist you in entering an element name, +attribute name or data value by using information about what is +allowed by the schema in that context. + +** proced.el provides a Dired-like interface for operating on +processes. Proced makes an Emacs buffer containing a listing of the +current processes. You can use the normal Emacs commands to move +around in this buffer, and special Proced commands to operate on the +processes listed. It is currently only functional on GNU/Linux, +MS-Windows and Solaris. + +** Remember Mode is a mode for jotting down things to remember. +Notes can be saved to a Diary file. For details, see the Remember +Manual. + +** RST mode is a major mode for editing reStructuredText files. + +** Ruby mode is a major mode for Ruby files. + +** Visual Line mode provides support for editing by visual lines. +It turns on word-wrapping in the current buffer, and rebinds C-a, C-e, +and C-k to commands that operate by visual lines instead of logical +lines. This is a more reliable replacement for longlines-mode. +This can also be turned on using the menu bar, via +Options -> Line Wrapping in this Buffer -> Word Wrap + +** xesam.el is an implementation of Xesam, an interface to (desktop) +search engines like Beagle, Strigi, and Tracker. The Xesam API +requires D-Bus for communication. + +** 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. + +** There is a new `whitespace' package. +(The pre-existing one has been renamed to `old-whitespace'.) +Now, besides reporting bogus blanks, the whitespace package has a +minor mode and a global minor mode to visualize blanks (TAB, (HARD) +SPACE and NEWLINE). The visualization is made via faces and/or display +table. It can also indicate lines that extend beyond a given column, +trailing blanks, and empty lines at the start or end of a buffer. +See `whitespace-style' for more details. The `whitespace-action' option +specifies what to do when a buffer is visited, killed, or written. + + +* Changes in Specialized Modes and Packages in Emacs 23.1 + +** Abbrev has been rewritten in Elisp and extended with more flexibility. + +*** New functions: abbrev-get, abbrev-put, abbrev-table-get, abbrev-table-put, +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. + +*** New variable `abbrev-minor-mode-table-alist'. + +*** `local-abbrev-table' can hold a list of abbrev-tables. + +*** Abbrevs have now the following special properties: +`:count', `:system', `:enable-function', `:case-fixed'. + +*** Abbrev-tables have now the following special properties: +`:parents', `:case-fixed', `:enable-function', `:regexp', +`abbrev-table-modiff'. + +** Apropos + +*** `apropos-library' describes the elements defined in a given library. + +*** Set `apropos-compact-layout' is you want a more compact (but wider) layout. + +** Archive Mode has basic support to browse Rar archives. +Note, however, that the free version of the unrar command only handles +versions 1 and 2 of the Rar format. + +** BibTeX mode + +*** New command `bibtex-initialize' (re)initializes BibTeX buffers. + +*** New `bibtex-entry-format' options `whitespace', `braces', and +`string', disabled by default. + +*** New variable `bibtex-cite-matcher-alist' contains rules to +identify cited keys in BibTeX entries, used by `bibtex-find-crossref'. + +*** Command `bibtex-url' allows multiple URLs per entry. + +** Bookmarks + +*** bookmark.el saves bookmarks in a pre-Emacs-23-incompatible file format +bookmark.el can read a .emacs.bmk file saved by an older Emacs, but an +older Emacs cannot read one saved by Emacs 23. + +** Calendar and diary + +*** There is a new date style, `iso', essentially year/month/day. +The variable `european-calendar-style' is obsolete - use `calendar-date-style'. +Similarly, the commands `american-calendar' and `european-calendar' +should be replaced by `calendar-set-date-style'. + +*** The calendar namespace has been rationalized. +All functions and variables now begin with a `calendar-', `diary-', or +`holiday-' prefix. The various calendar systems have secondary +prefixes, eg `calendar-french-'. The old names you are likely to use +directly still exist, for the time being, as aliases, but please start +using the new names. + +*** The whitespace in the calendar layout can be customized. +See the variables: +calendar-left-margin, calendar-intermonth-spacing, calendar-column-width, +calendar-day-header-width, and calendar-day-digit-width. + +*** Text (e.g. ISO weeks) can be displayed between the calendar months. +See the variables calendar-intermonth-header and calendar-intermonth-text. + +*** 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). + +** Change Log mode + +*** The new command C-c C-f (change-log-find-file) finds the file +associated with the current log entry. + +*** The new command C-c C-c (change-log-goto-source) goes to the +source code associated with a log entry. + +** Compile and grep modes + +*** The mode-line entry for the *compilation* and *grep* buffer is color coded. +It has different colors for to show that: (a) the command is still +running, (b) successful completion, (c) error. + +*** compilation-auto-jump-to-first-error tells `compile' to jump to +the first error encountered during compilations. + +*** compilation-scroll-output accepts a new value, `first-error', which +says to stop auto scrolling at the first error that occurs. + +*** The `cc' alias for C++ files in `grep-file-aliases' has been +improved. `hh' can be used to match C++ header files and `cchh' both +C++ sources and headers. + +** Copyright + +*** You can specify your copyright holders' names. +Only copyright lines with holders matching `copyright-names-regexp' are +considered for update. + +*** Copyrights can be at the end of the buffer. +This is controlled by `copyright-at-end-flag' (used by, e.g., change-log-mode). + +** Custom + +*** defcustom accepts new keyword arguments, `:safe' and `:risky', which +set a variable's `safe-local-variable' and `risky-local-variable' property. + +** Diff mode + +*** diff-refine-hunk highlights word-level details of changes in a diff hunk. +It's used automatically as you move through hunks, see +diff-auto-refine-mode. It is bound to `C-c C-b'. + +*** diff-add-change-log-entries-other-window iterates through the diff +buffer and tries to create ChangeLog entries for each change. +It is bound to `C-x 4 A'. + +*** Turning on `whitespace-mode' in a diff buffer will show trailing +whitespace problems in the modified lines. + +** Dired + +*** In Dired, C-x C-q now runs the command wdired-change-to-wdired-mode, +and C-x C-q in wdired-mode exits it with asking a question about +saving changes. + +*** `&' runs the command `dired-do-async-shell-command' that executes +the command asynchronously without the need to manually add ampersand +to the end of the command. Its output appears in the buffer `*Async Shell +Command*'. + +*** `M-s f C-s' and `M-s f M-C-s' run Isearch that matches only at file names. +When a new user option `dired-isearch-filenames' is t, then even ordinary +Isearch started with `C-s' and `C-M-s' matches only at file names in the +Dired buffer. When `dired-isearch-filenames' is `dwim' then activation of +file name Isearch depends on the position of point - if point is on a file +name initially, then Isearch matches only file names, otherwise it matches +everywhere in the Dired buffer. You can toggle file names matching on or +off by typing `M-s f' in Isearch mode. + +*** `M-s a C-s' and `M-s a M-C-s' run multi-file Isearch on the marked files. +They visit the first marked file in the sequence and display the usual Isearch +prompt for a string or a regexp where all Isearch commands are available. + +*** `Q' in Dired provides two new keys for multi-file replacement. +The upper case key `Y' replaces all remaining matches in all remaining files +with no more questions. The upper case key `N' stops doing replacements +in the current file and skips to the next file. These multi-file keys +are available for all commands that use `tags-query-replace' +including `dired-do-query-replace-regexp', `vc-dir-query-replace-regexp', +`reftex-query-replace-document'. + +** Fortran + +*** The line length of fixed-form Fortran is not fixed at 72 any more. +Customize the variable `fortran-line-length' to change it. + +*** In Fortran mode, M-; is now bound to the standard comment-dwim, +rather than fortran-indent-comment. + +*** (The increasingly misnamed) F90 mode supports Fortran 2003 syntax. + +** Gnus + +*** The Gnus package has been updated +There are many new features, bug fixes and improvements; see the file +GNUS-NEWS or the node "No Gnus" in the Gnus manual for details. + +*** In Emacs 23, Gnus uses Emacs' new internal coding system `utf-8-emacs' for +saving articles, drafts, and ~/.newsrc.eld. These file may not be read +correctly in Emacs 22 and below. If you want to Gnus across different Emacs +versions, you may set `mm-auto-save-coding-system' to `emacs-mule'. + +*** Passwords are consistently loaded through `auth-source' +Gnus can use `auth-source' for POP and IMAP passwords. Also see that +`smtpmail' and `url' support `auth-source' for SMTP and HTTP/HTTPS/RSS +authentication respectively. + +** Help mode + +*** New macro `with-help-window' should set up help windows better +than `with-output-to-temp-buffer' with `print-help-return-message'. + +*** New option `help-window-select' permits to customize whether help +window shall be automatically selected when invoking help. + +*** New variable `help-window-point-marker' permits one to specify a new +position for point in help window (for example in `view-lossage'). + +** Isearch + +*** New command `isearch-forward-word' bound globally to `M-s w' starts +incremental word search. New command `isearch-toggle-word' bound to the +same key `M-s w' in Isearch mode toggles word searching on or off +while Isearch is active. + +*** New command `isearch-highlight-regexp' bound to `M-s h r' in Isearch +mode runs `highlight-regexp' (`hi-lock-face-buffer') with the current +search string as its regexp argument. The same key `M-s h r' and +other keys on the `M-s h' prefix are bound globally to the command +`highlight-regexp' and other hi-lock commands. + +*** New command `isearch-occur' bound to `M-s o' in Isearch mode +runs `occur' with the current search string. The same key `M-s o' +is bound globally to the command `occur'. + +*** Isearch can now search through multiple ChangeLog files. +When running Isearch in a ChangeLog file, if the search fails, +then another C-s tries searching the previous ChangeLog, +if there is one (e.g. going from ChangeLog to ChangeLog.12). +This is enabled if multi-isearch-search is non-nil. + +*** Two new commands to start Isearch on a list of marked buffers +for buff-menu.el and ibuffer.el are bound to the keys `M-s a C-s' and +`M-s a M-C-s'. + +*** 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 for Isearch mode. All the other Help commands exit +Isearch mode and execute their global definitions. + +*** When started in the minibuffer, Isearch searches in the minibuffer +history. See `Minibuffer changes', above. + +** MH-E + +*** Upgraded to MH-E version 8.2. See MH-E-NEWS for details. + +** Python +*** The file etc/emacs.py now supports both Python 2 and 3, meaning +that either version can be used as inferior Python by python.el. + +*** Python mode now has `pdbtrack' functionality. When using pdb to +debug a Python program, pdbtrack notices the pdb prompt and displays +the source file and line that the program is stopped at, much the same +way as gud-mode does for debugging C programs with gdb. + +** Recentf + +*** The default value of `recentf-keep' prevents from checking of +remote files, if there is no established connection to the +corresponding remote host. + +** Rmail + +*** Rmail no longer converts the messages to Babyl format. +Instead, it uses UNIX mbox format, both on disk and in Rmail buffers, +and does conversion and decoding when a message is displayed. + +The first time you visit an Rmail file in Babyl format, Rmail +automatically converts it to mbox format. This is a one-time +conversion, but it can take a few minutes, depending on how fast is +your machine and on the size of the file. You should find the rest of +Rmail usage unaltered. + +However, M-x set-rmail-inbox-list now lasts only for one session +because there is no way to save the list of inbox files in an +mbox-format file. + +Also, whereas with Babyl format M-x find-file would switch to Rmail +mode, with mbox format this is no longer the case (there being no way +to add an "-*- rmail-*-" cookie to an mbox file). Use C-u M-x rmail +instead. + +If you have written any extensions to Rmail, they are likely to need +updating. Conceptually, the Rmail buffer that you see is no longer +just a narrowed portion of the whole. So you cannot access the whole +of a message (or message collection) by a simple save-restriction and +widen. Instead, there are two buffers: the rmail-buffer, and the +rmail-view-buffer. The former is the buffer that you see, the latter +is invisible. Most of the time, the invisible `view' buffer contains +the full contents of the Rmail file, and the Rmail buffer contains a +decoded copy of the current message (with only a subset of the +headers). In this state, Rmail is said to be `swapped'. + +You may find the following functions useful: + +`rmail-get-header' and `rmail-set-header' get or set the value of a +message header, whether or not it is currently visible. + +`rmail-apply-in-message' is a general purpose function that calls a +function (with arguments) which you specify on the full text of a given +message. To further narrow to just the headers, search forward for "\n\n". + +*** The new command `rmail-mime' displays MIME messages. +It is bound to `v' in Rmail buffers and summaries. It displays plain +text and multipart messages in a temporary buffer, and offers buttons +to save attachments. + +*** The command `rmail-redecode-body' no longer accepts the optional arg RAW. +Since Rmail now holds messages in their original undecoded form in a +separate buffer, `rmail-redecode-body' no longer encodes the original +message, and therefore there should be no need to avoid encoding it. + +*** The o command is now `rmail-output'. It is an all-purpose command +for copying messages from Rmail and appending them to files. It +handles Babyl-format files as well as mbox-format files, and it +handles both kinds properly when they are visited in Emacs. It always +copies the full headers of the message. + +*** The C-o command is now `rmail-output-as-seen'. It uses +the message as displayed, appending it to an mbox file. + +*** The modified status of the Rmail buffer is reported in the mode-line. +Previously, this information was hidden. + +** TeX modes + +*** New option latex-indent-within-escaped-parens +permits to customize indentation of LaTeX environments delimited +by escaped parens. + +** T-mouse Mode + +*** If the gpm mouse server is running and t-mouse-mode is enabled, +Emacs uses a Unix socket in a GNU/Linux console to talk to server, +rather than faking events using the client program mev. This C level +approach provides mouse highlighting and help echoing in the +minibuffer. + +** Tramp + +*** New connection methods. +The new methods "plinkx", "plink2", "psftp", "sftp" and "fish" have +been introduced. There are also new so-called gateway methods +"tunnel" and "socks". + +*** IPv6 addresses. +IPv6 addresses are supported now as host names. They must be embedded +in square brackets, like in "/ssh:[::1]:". + +*** Multihop syntax has been removed. +The pseudo-method "multi" has been removed. Instead, multi hops +can be specified by the new variable `tramp-default-proxies-alist'. + +*** More default settings. +Default values can be set via the variables `tramp-default-user', +`tramp-default-user-alist' and `tramp-default-host'. + +*** Connection information is cached. +In order to reduce connection setup, information about used +connections is kept persistently in a file. The name of this file is +defined in the variable `tramp-persistency-file-name'. + +*** Control of remote processes. +Running processes on a remote host can be controlled by settings in +`tramp-remote-path' and `tramp-remote-process-environment'. + +*** Success of remote copy is checked. +When the variable `file-precious-flag' is set, the success of a remote +file copy is checked via the file's checksum. + +*** Passwords can be read from an authentification file. +Tramp uses the package `auth-source' to read passwords from a file, if +necessary. + +** VC and related modes + +*** 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. + +*** vc-dir is a new command that displays file names and their VC +status. It allows to apply various VC operations to a file, a +directory or a set of files/directories. + +*** VC switches are no longer appended, rather the first non-nil value is used. +(This was for the most part true in Emacs 22, but was not advertised). +This is because there is an increasing variety of VC systems, and they +do not all accept the same "common" options. For example, a CVS diff +command used to append the values of `vc-cvs-diff-switches', +`vc-diff-switches', and `diff-switches'. Now the first non-nil value +from that sequence is used. The special value `t' means "no switches". + +*** Clicking on the VC mode-line entry now pops the VC menu. + +*** The VC mode-line entry now has a tooltip that explains the VC file status. + +*** In VC Annotate mode, the key bindings have changed to use lower +case keys instead of the upper case keys used in the past. + +*** In VC Annotate mode, for VC systems that support changesets, you can +see the diff for the whole changeset (not only for the current file) +by typing the D key. Using the "Show changeset diff of revision at +line" menu entry does the same thing. + +*** In VC Annotate mode, you can type v to toggle the annotation visibility. + +*** In VC Annotate mode, you can type f to show the file revision on +the current line. + +*** Asynchronous VC commands display [Waiting...] in the mode-line +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. + +*** In log-view-mode, for VC systems that support changesets, you can +see the diff for the whole changeset (not only for the current file) +by typing the D key or using the "Changeset Diff" menu entry. + +*** In Log Edit mode, C-c C-d now shows the diff for the files involved. + +*** vc-git supports the "git grep" command. + +*** VC Support for Meta-CVS has been removed for lack of a maintainer able +to update it to the new VC. + +** Miscellaneous + +*** 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. + +*** Eldoc highlights the function argument under point +with the face `eldoc-highlight-function-argument'. + +*** In Etags, the --members option is now the default. +Use --no-members if you want the old default behavior of not tagging +struct members in C, members variables in C++ and variables in PHP. + +*** The `gdb' command only works with the graphical interface now. +Use `gud-gdb' if you want the (old) text command mode. + +*** goto-address.el provides two new minor modes, goto-address-mode and +goto-address-prog-mode, which buttonize URLS and email addresses. + +*** The new command `eshell/info' runs info in an eshell buffer. + +*** The new variable `ffap-rfc-directories' specifies a list of local +directories in which `ffap-rfc' will first search for RFCs. + +*** hide-ifdef-mode allows shadowing ifdef-blocks instead of hiding them. +See option `hide-ifdef-shadow' and function `hide-ifdef-toggle-shadowing'. + +*** `icomplete-prospects-height' now supercedes `icomplete-prospects-length'. + +*** Info displays breadcrumbs in the header of the page. +See Info-breadcrumbs-depth to control it. + +*** net-utils has an `iwconfig' command, similar to the existing `ifconfig'. +It is used to configure wireless interfaces. + +*** The pcmpl-unix package supports hostname completion for ssh and scp. + +*** sgml-electric-tag-pair-mode lets you simultaneously edit matched tag pairs. + +*** smerge-refine highlights word-level details of changes in conflict. +It's used automatically as you move through conflicts, see +smerge-auto-refine-mode. + +*** talk.el has been extended for multiple tty support. + +*** A new command `display-time-world' has been added to the Time +package. It creates a buffer with an updating time display using +several time zones. + +*** The appearance of superscript and subscript in TeX is more customizable. +See the documentation of the variables: tex-fontify-script, +tex-font-script-display, tex-suscript-height-ratio, and +tex-suscript-height-minimum. + +*** view-remove-frame-by-deleting is now by default t +since users found iconification of view-mode frames distracting. + +*** WoMan tries to add locale-specific manual page directories to the +search path. This can be disabled by setting `woman-locale' to nil. + + +* Changes in Emacs 23.1 on non-free operating systems + +** Case is now considered significant in completion on MS-Windows. +The default value of `completion-ignore-case' is now nil on +MS-Windows, the same as it is for other operating systems. The +variable doesn't apply to reading a file name -- in that case Emacs +heeds `read-file-name-completion-ignore-case' instead. + +** IPv6 is supported on MS-Windows. +Emacs now supports IPv6 on Windows XP and later, and earlier versions +of Windows with third party IPv6 stacks installed. In Emacs 22, IPv6 was +supported on other platforms, but not on Windows due to using the winsock +1.1 header file, even though Emacs was linking to the winsock 2 library. + +** Busy cursor (hourglass) now displays on MS-Windows. +When Emacs is busy, an hourglass mouse cursor is displayed on Windows. +In Emacs 22 only X supported the busy cursor. + +** Battery status is available on MS-Windows +Emacs can now display the battery status in the mode-line when enabled with +display-battery-mode or from the Options menu. More verbose battery +information is also available with the command `battery'. In Emacs 22 +battery status was supported only on GNU/Linux and Mac. + +** More keys available on MS-Windows. +Keys normally associated with IMEs, and some exotic keys not normally found +on standard keyboards have been given names so they can be bound to functions +inside Emacs. If there are keys on your keyboard that have not been exposed +to Emacs in the past, try C-h k to see if they are available now. + +Emacs can now bind functions to the extra buttons for media player and +browser control present on some keyboards. These buttons are disabled +by default, since enabling them prevents their system-wide use when +Emacs has focus. To enable them, set the variable +w32-pass-multimedia-buttons to nil. See the doc string of that variable +for the list of extra keys that are available. + +** BDF fonts no longer supported on MS-Windows. +The font backend was completely rewritten for this release. The focus +on Windows has been getting acceptable performance and full unicode +support, including complex script shaping for native Windows fonts. A +rewrite of the BDF font support has not happened due to lack of time +and developers. If demand still exists for such a backend even with +the improved language support for native Windows fonts, future +development in this direction will most likely be based on the +freetype library, giving access to a wider range of font formats. + + +* Incompatible Lisp Changes in Emacs 23.1 + +** Variables cannot be both buffer-local and frame-local any more. + +** `functionp' returns nil for special forms. +I.e., it only returns t for objects that can be passed to `funcall'. + +** The behavior of map-char-table has changed. It may call the +specified function with a cons (FROM . TO) as a key if characters in +that range have the same value. + +** Process changes + +*** The function `dired-call-process' has been removed. + +*** The multibyteness of process filters is now determined by the +coding-system used for decoding. The functions +`process-filter-multibyte-p' and `set-process-filter-multibyte' are +obsolete. + +** The variable `byte-compile-warnings' can now be a list starting with `not', +meaning to disable the specified warnings. The meaning of this list +may therefore be the reverse of what you expect (of course, this is +only an issue if you make use of the new `not' syntax). Rather than +checking/manipulating elements directly, use the new functions +`byte-compile-warning-enabled-p', `byte-compile-disable-warning', and +`byte-compile-enable-warning.' + +** `mode-name' is no longer guaranteed to be a string. +Use `(format-mode-line mode-name)' to ensure a string value. + +** The function x-font-family-list has been removed. +Use the new function font-family-list (see Lisp Changes, below). + +** Internationalization changes + +*** The value of the function `charset-id' is now always 0. + +*** The functions `register-char-codings' and `coding-system-spec' +have been removed. + +*** The cpXXX coding systems are now supported automatically. +The functions cp-...-codepage, which you had to use in Emacs 22 to +enable support for these coding systems, have been deleted. + +*** The following features have been removed. They were used for +displaying various scripts with specific fonts, and are no longer +needed now that OpenType font support is available: + +**** `devanagari' and `devan-util', and all associated devanagari-* and +dev-* functions and variables (formerly used for Devanagari script). + +**** `kannada' and `knd-util', and all associated kannada-* and knd-* +functions and variables (formerly used for Kannada script). + +**** `malayalam' and `mlm-util', and all associated malayalam-* and +mlm-* functions and variables (formerly used for Malayalam script). + +**** `tamil' and `tml-util, and all associated tamil-* and tml-* +functions and variables (formerly used for Tamil script). + +*** The meaning of NAME argument of `set-fontset-font' is changed. +Previously nil is accepted as the default fontset. Now, nil is for +the fontset of the selected frame and t is for the default fontset. + +*** The meaning of FONTSET argument of `print-fontset' is changed. +Now, nil is for the fontset of the selected frame and t is for the +default fontset. + +** If a function in write-region-annotate-functions returns with a +different buffer current, Emacs no longer kills that buffer +automatically. This behavior existed in previous versions of Emacs, +but was undocumented. To kill a buffer after write-region, give the +variable `write-region-post-annotation-function' a buffer-local value +of `kill-buffer'. + +** The variable temp-file-name-pattern has been removed. +This variable was only used by call-process-region, which now uses +temporary-file-directory instead. + +** The COUNT and SYSTEM-FLAG arguments to define-abbrev have been +removed. The function now takes extra arguments for specifying +arbitrary abbrev properties. + +** end-of-defun-function is now guaranteed to work only when called +from the start of a defun. It must now leave point exactly at the end +of defun, since `end-of-defun' now itself moves forward over +whitespace after calling it. + + +* Lisp Changes in Emacs 23.1 + +** The new variable `generate-autoload-cookie' controls the magic comment +string used by `update-file-autoloads' to find autoloaded forms. The +variable `generated-autoload-file' similarly controls the name of the +file where `update-file-autoloads' writes the calls to `autoload'. +The default values are ";;;###autoload" and `loaddefs.el', +respectively. + +** New primitives `list-system-processes' and `process-attributes' +let Lisp programs access the processes that are running on the local +machine. See the doc strings of these functions for more details. +Not all platforms support accessing this information; on those that +don't, these primitives will return nil. + +** New variable `user-emacs-directory'. +Use this instead of "~/.emacs.d". + +** If a local hook function has a non-nil `permanent-local-hook' +property, `kill-all-local-variables' does not remove it from the local +value of the hook variable; it remains even if you change major modes. + +** `frame-inherited-parameters' lets new frames inherit parameters from +the selected frame. + +** New keymap `input-decode-map' overrides like key-translation-map, but +applies before function-key-map. Also it is terminal-local contrary to +key-translation-map. Terminal-specific key-sequences are generally added to +this map rather than to function-key-map now. + +** `ignore-errors' is now a standard macro (does not require the CL package). + +** `interprogram-paste-function' can now return one string or a list +of strings. In the latter case, Emacs puts the second and following +strings on the kill ring. + +** In `condition-case', a handler can specify "let the debugger run first". +You do this by writing `debug' in the list of conditions to be handled, +like this: + + (condition-case nil + (foo bar) + ((debug error) nil)) + +** clone-indirect-buffer now runs the clone-indirect-buffer-hook. + +** `beginning-of-defun-function' now takes one argument, the count given to +`beginning-of-defun'. (N.B. `end-of-defun-function' doesn't take any +arguments.) + +** `file-remote-p' has new optional parameters IDENTIFICATION and CONNECTED. +IDENTIFICATION specifies which part of the remote identifier has to be +returned. With CONNECTED passed non-nil, it is checked whether a +remote connection has been established already. + +** The new macro `declare-function' suppresses compiler warnings about +undefined functions. + +** Changes to interactive function handling + +*** The new interactive spec code ^ says to first call +handle-shift-selection if shift-select-mode is non-nil, before reading +the command arguments. This is used for shift-selection (see above). + +*** Built-in functions can now have an interactive specification that +is not a prompt string. If the `intspec' parameter of a `DEFUN' +starts with a `(', the string is evaluated as a Lisp form. + +*** The interactive-form of a function can be added post-facto via the +`interactive-form' symbol property. Mostly useful to add complex +interactive forms to subroutines. + +** Region changes + +*** Commands should use `use-region-p' to test whether there is +an active region that they should operate on. + +*** `region-active-p' returns non-nil when Transient Mark mode is +enabled and the mark is active. Most commands that act specially on +the active region in Transient Mark mode should use `use-region-p' +instead of `region-active-p', because `use-region-p' obeys the new +user option `use-empty-active-region' (see Editing Changes, above). + +*** If a command sets `transient-mark-mode' to (only . OLDVAL), that +means to activate transient-mark-mode temporarily, until the next +unshifted point motion command or mark deactivation. Afterwards, +reset transient-mark-mode to the value OLDVAL. The values `only' and +`identity', introduced in Emacs 22, are now deprecated. + +** Emacs session information + +*** The new variables `before-init-time' and `after-init-time' record the +value of `current-time' before and after Emacs loads the init files. + +*** The new function `emacs-uptime' returns the uptime of an Emacs instance. + +*** The new function `emacs-init-time' returns the duration of the +Emacs initialization. + +** Changes affecting display-buffer + +*** display-buffer tries to be smarter when splitting windows. +The new option split-window-preferred-function lets you specify your own +function to pop up new windows. Its default value split-window-sensibly +can split a window either vertically or horizontally, whichever seems +more suitable in the current configuration. You can tune the behavior +of split-window-sensibly by customizing split-height-threshold and the +new option split-width-threshold. Both options now take the value nil +to inhibit splitting in one direction. Setting split-width-threshold to +nil inhibits horizontal splitting and gets you the behavior of Emacs 22 +in this respect. In any case, display-buffer may now split the largest +window vertically even when it is not as wide as the containing frame. + +*** If pop-up-frames has the value `graphic-only', display-buffer only +makes a separate frame on graphic displays. + +*** select-frame and set-frame-selected-window have a new optional +argument NORECORD. If non-nil, this will avoid messing with the order +of recently selected windows and the buffer list. + +** Window parameters can now be defined. +These are analogous to frame parameters, but are associated with +individual windows. + +*** The new functions window-parameters, window-parameter, and +set-window-parameter are used to query and set window parameters. + +** Minibuffer and completion changes + +*** A list of default values can be specified for the DEFAULT argument of +functions `read-from-minibuffer', `read-string', `read-command', +`read-variable', `read-buffer', `completing-read'. Elements of this list +are available for inserting into the minibuffer by typing `M-n'. +For empty input these functions return the first element of this list. + +*** New function `read-regexp' uses the regexp history and some useful +regexp defaults (string at point, last Isearch/replacement regexp/string) +via M-n when reading a regexp in the minibuffer. + +*** minibuffer-local-must-match-filename-map is now named +minibuffer-local-filename-must-match-map. + +*** The `require-match' argument to `completing-read' accepts the new +values `confirm-only' and `confirm-after-completion'. + +** Search and replacement changes + +*** The regexp form \(?:\) specifies the group number explicitly. + +*** New function `match-substitute-replacement' returns the result of +`replace-match' without actually using it in the buffer. + +*** The new variable `replace-search-function' determines the function +to use for searching in query-replace and replace-string. The +function it specifies is called by `perform-replace' when its 4th +argument is nil. + +*** The new variable `replace-re-search-function' determines the +function to use for searching in `query-replace-regexp', +`replace-regexp', `query-replace-regexp-eval', and +`map-query-replace-regexp'. The function it specifies is called by +`perform-replace' when its 4th argument is non-nil. + +*** New keymap `search-map' bound to `M-s' provides global bindings +for search related commands. + +*** New keymap `multi-query-replace-map' contains additonal keys bound +to `automatic-all' and `exit-current' for multi-buffer interactive replacement. + +*** The variable `inhibit-changing-match-data', if non-nil, prevents +the search and match primitives from changing the match data. + +*** New functions `word-search-forward-lax' and `word-search-backward-lax'. +These are like `word-search-forward and `word-search-backward', except +that the end of the search string need not match a word boundary, +unless it ends in whitespace. + +** File handling changes + +*** set-file-modes is now interactive and can take the mode value in +symbolic notation thanks to auxiliary functions. + +*** file-local-variables-alist stores an alist of file-local +variables defined in the current buffer. + +** Face-remapping + +*** Each face can be remapped to a different face definition using the +variable `face-remapping-alist'. This is an alist that maps faces to +replacement definitions (which can be face names, lists of face names, +or attribute/value plists. If this variable is buffer-local, the +remapping occurs only in that buffer. + +*** text-scale-mode remaps the default face to a larger or smaller +size in the current buffer. This feature is used by the Buffer Face +menu and the new `C-x C-+', `C-x C--', and `C-x C-0' commands (see +Editing Changes, above). + +*** New functions: + +**** `face-remap-add-relative' adds a face remapping entry to the +current buffer. + +**** ``face-remap-remove-relative' removes a face remapping entry from +the current buffer. + +**** `face-remap-reset-base' restores a face to its global definition. + +**** `face-remap-set-base' sets the base remapping of a face. + +** Process changes + +*** The new function `start-file-process' is similar to `start-process', +but obeys file handlers. The file handler is chosen based on +`default-directory'. The functions `start-file-process-shell-command' +and `process-file-shell-command' are also new; they call internally +`start-file-process' and `process-file', respectively. + +*** The new function `process-lines' executes an external program and +returns its output as a list of lines. + +** Character code, representation, and charset changes. + +*** In multibyte buffers and strings, characters are represented by +UTF-8 byte sequences. The character code space is now 0x0..0x3FFFFF +with no gap; code points 0x0..0x10FFFF are Unicode characters of the +same code points, while code points 0x3FFF80..0x3FFFFF are raw 8-bit +bytes. + +*** Generic characters no longer exist. + +*** The concept of a charset has changed. A single character may +belong to multiple charsets (e.g. a-grave, U+00E0, belongs to charsets +unicode, iso-8859-1, iso-8859-3, etc). + +**** The dimension of a charset is now 1, 2, 3, or 4, and the size of +each dimension is no longer limited to 94 or 96. + +**** A dynamic charset priority list is used to infer the charset of +characters for display. + +*** The functions `split-char' and `make-char' now accept up to 4 +positional codes instead of just 2. + +*** The functions `encode-char' and `decode-char' now accept any character sets. + +*** The function `define-charset' now accepts a completely different +form of arguments (old-style arguments still work). + +*** The value of the function `char-charset' depends on the current +priorities of charsets. + +*** The function get-char-code-property now accepts many Unicode base +character properties. They are `name', `general-category', +`canonical-combining-class', `bidi-class', `decomposition', +`decimal-digit-value', `digit-value', `numeric-value', `mirrored', +`old-name', `iso-10646-comment', `uppercase', `lowercase', and +`titlecase'. + +*** The functions `modify-syntax-entry' and `modify-category-entry' now +accept a cons of characters as the first argument, and modify all +entries in that range of characters. + +*** Use of `translation-table-for-input' for character code unification +is now obsolete, since Emacs 23.1 and later uses Unicode as basis for +internal representation of characters. + +*** New functions: + +**** `characterp' returns t if and only if the argument is a character. +This replaces `char-valid-p', which is now obsolete. + +**** `max-char' returns the maximum character code (currently #x3FFFFF). + +**** `define-charset-alias' defines an alias of a charset. + +**** `set-charset-priority' sets priorities of charsets. + +**** `charset-priority-list' returns a prioritized list of charsets. + +**** `unibyte-string' makes a unibyte string from bytes. + +**** `define-char-code-property' defines a character code property. + +**** `char-code-property-description' returns the description string of +a character code property. + +*** New variables: + +**** `find-word-boundary-function-table' is a char-table of functions to +search for a word boundary. + +**** `char-script-table' is a char-table of script names. + +**** `char-width-table' is a char-table of character widths. + +**** `print-charset-text-property' controls how to handle `charset' text +property on printing a string. + +**** `printable-chars' is a char-table of printable characters. + +** Code conversion changes + +*** The new function `define-coding-system' should be used to define a +coding system instead of `make-coding-system' (which is now obsolete). + +*** The functions `encode-coding-region' and `decode-coding-region' +have an optional 4th argument to specify where the result of +conversion should go. + +*** The functions `encode-coding-string' and `decode-coding-string' +have an optional 4th argument specifying a buffer to store the result +of conversion. + +*** The new variable `inhibit-null-byte-detection' controls whether to +consider text with null bytes as binary data. By default, it is +`nil', and Emacs uses `no-conversion' for any text containing null +bytes. + +*** The functions `set-coding-priority' and `make-coding-system' are obsolete. + +*** New functions: + +**** `with-coding-priority' executes Lisp code using the specified +coding system priority order. + +**** `check-coding-systems-region' checks if the text in the region is +encodable by the specified coding systems. + +**** `coding-system-aliases' returns a list of aliases of a coding system. + +**** `coding-system-charset-list' returns a list of charsets supported +by a coding system. + +**** `coding-system-priority-list' returns a list of coding systems +ordered by their priorities. + +**** `set-coding-system-priority' sets priorities of coding systems. + +**** `coding-system-from-name' returns a coding system matching with +the argument name. + +** There is a new input method, Robin, different from Quail. +It has three functionalities: + i) a simple input method (converts an ASCII sequence into a string). +ii) converts an existing buffer substring into another string +iii) reverse conversion (each character produced by a +robin rule can hold the original ASCII sequence as a char-code-property) + +*** The new function `robin-define-package' defines a Robin package. + +*** The new function `robin-modify-package' modifies an existing Robin package. + +*** The new function `robin-use-package' starts using a Robin package +as an input method. + +*** The new function `string-to-unibyte' is like `string-as-unibyte' +but signals an error if STRING contains a non-ASCII, non-eight-bit +character. + +** Changes related to the new font backend + +*** Which font backends to use can be specified by the X resource +"FontBackend". For instance, to use both X core fonts and Xft fonts: + +Emacs.FontBackend: x,xft + +If this resource is not set, Emacs tries to use all font backends +available on your graphic device. + +*** New frame parameter `font-backend' specifies a list of +font-backends supported by the frame's graphic device. On X, they are +currently `x' and `xft'. + +*** The function `set-fontset-font' now accepts a script name as the +second argument, and has an optional 5th argument to control how to +set the font. + +*** New functions: + +**** `fontp' checks if the argument is a font-spec or font-entity. + +**** `font-spec' creates a new font-spec object. + +**** `font-get' returns a font property value. + +**** `font-put' sets a font property value. + +**** `font-face-attributes' returns a plist of face attributes set by a font. + +**** `list-fonts' returns a list of font-entities matching a font spec. + +**** `find-font' returns the font-entity best matching the given font spec. + +**** `font-family-list' returns a list of family names of available fonts. + +**** `font-xlfd-name' returns an XLFD name of a given font spec, font +entity, or font object. + +**** `clear-font-cache' clears all font caches. + +** Changes related to multiple-terminal (multi-tty) support + +*** $TERM is now set to `dumb' for subprocesses. If you want to know the +$TERM inherited by Emacs you will have to look inside initial-environment. + +*** $DISPLAY is now dynamically inherited from the frame's `display'. + +*** The `window-system' variable is now frame-local. The new +`initial-window-system' variable contains the `window-system' value +for the first frame. `window-system' is also now a function that +takes a frame argument. + +*** The `keyboard-translate-table' variable and the terminal and +keyboard coding systems are now terminal-local. + +*** You can specify a terminal device (`tty' parameter) and a terminal +type (`tty-type' parameter) to `make-terminal-frame'. + +*** The function `make-frame-on-display' now works during a tty +session. + +*** A new `terminal' data type. +The functions `get-device-terminal', `terminal-parameters', +`terminal-parameter', `set-terminal-parameter' use this data type. + +*** Function key sequences are now mapped using `local-function-key-map', +a new variable. This inherits from the global variable function-key-map, +which is not used directly any more. + +*** New hooks: + +**** before-hack-local-variables-hook is called after setting new +variable file-local-variables-alist, and before actually applying the +file-local variables. + +**** `suspend-tty-functions' and `resume-tty-functions' are called +after a tty frame has been suspended or resumed, respectively. The +functions are called with the terminal id of the frame being +suspended/resumed as a parameter. + +**** The special hook `delete-terminal-functions' is called before +deleting a terminal. + +*** New functions: + +**** `delete-terminal' + +**** `suspend-tty' + +**** `resume-tty'. + +*** `initial-environment' holds the environment inherited from Emacs's parent. + +** Redisplay changes + +*** For underlined characters, the distance between the underline and +the baseline is controlled by a new variable, `underline-minimum-offset'. + +*** You can now pass the value of the `invisible' property to +invisible-p to check whether it would cause the text to be invisible. +This is convenient when checking invisibility of text with no buffer +position (e.g. in before/after-strings). + +*** `clear-image-cache' can be told to flush only images of a specific file. + +*** `vertical-motion' can now be given a goal column. +It now accepts a cons cell (COLS . LINES) in its first argument, which +says to stop, where possible, at a pixel x-position equal to COLS +times the default column width. + +*** redisplay-end-trigger-functions, set-window-redisplay-end-trigger, +and window-redisplay-end-trigger are obsolete. Use `jit-lock-register' +instead. + +*** The new variables `wrap-prefix' and `line-prefix' specify display +specs which are appended at display-time to every continuation line +and non-continuation line, respectively. In addition, Emacs +recognizes the `wrap-prefix' and `line-prefix' text or overlay +properties; these have the same effects as the variables of the same +name, but take precedence. + +** The Lisp interpreter now treats non-breaking space as whitespace. + +** Miscellaneous new functions + +*** `apply-partially' performs a "curried" application of a function. + +*** `buffer-swap-text' swaps text between two buffers. This can be +useful for modes such as tar-mode, archive-mode, RMAIL. + +*** `combine-and-quote-strings' produces a single string from a list of strings +sticking a separator string in between each pair, and quoting those +strings that include the separator as their substring. Useful for +consing shell command lines from the individual arguments. + +*** `custom-note-var-changed' tells Custom to treat the change in a +certain variable as having been made within Custom. + +*** `face-all-attributes' returns an alist describing all the basic +attributes of a given face. + +*** `format-seconds' converts a number of seconds into a readable +string of days, hours, etc. + +*** `image-refresh' refreshes all images associated with a given image +specification. + +*** `locate-user-emacs-file' helps packages to select the appropriate +place to save user-specific files. It defaults to `user-emacs-directory' +unless the file already exists at $HOME. + +*** `read-color' reads a color name using the minibuffer. + +*** `read-shell-command' does what its name says, with completion. It +uses the minibuffer-local-shell-command-map for that. + +*** `split-string-and-unquote' splits a string into a list of substrings +on the boundaries of a given delimiter, and unquotes the substrings that +are quoted. Useful for taking apart shell commands. + +*** The two new functions `looking-at-p' and `string-match-p' can do +the same matching as `looking-at' and `string-match' without changing +the match data. + +*** The two new functions `make-serial-process' and +`serial-process-configure' provide a Lisp interface to the new serial +port support (see Emacs changes, above). + +** Miscellaneous new variables + +*** `auto-save-include-big-deletions', if non-nil, means auto-save is +not turned off automatically after a big deletion. + +*** `read-circle', if nil, disables the reading of recursive Lisp +structures using the #N= and #N# syntax. + +*** `this-command-keys-shift-translated' is non-nil if the key +sequence invoking the current command was found by shift-translation. + +*** `window-point-insertion-type' determines the insertion-type of the +marker used for window-point. + +*** bookmark provides `bookmark-make-record-function' so special major +modes like Info can teach bookmark.el how to save and restore the +relevant data. + +*** `fill-forward-paragraph-function' specifies which function the +filling code should use to find paragraph boundaries. + + +* New Packages for Lisp Programming in Emacs 23.1 + +** The new package avl-tree.el deals with the AVL tree data structure. + +** The new package check-declare.el verifies the accuracy of +declare-function macros (see Lisp Changes, above). + +** find-cmd.el can build `find' commands using lisp syntax. + +** The package misearch.el has been added. It allows Isearch to search +through multiple buffers. A variable `multi-isearch-next-buffer-function' +defines the function to call to get the next buffer to search in the series +of multiple buffers. Top-level functions `multi-isearch-buffers', +`multi-isearch-buffers-regexp', `multi-isearch-files' and +`multi-isearch-files-regexp' accept a single argument that specifies +a list of buffers/files to search for a string/regexp. + +** The new major mode `special-mode' is intended as a parent for +major modes such as those that set the "'mode-class 'special" property. + + +---------------------------------------------------------------------- +This file is part of GNU Emacs. + +GNU Emacs is free software: you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation, either version 3 of the License, or +(at your option) any later version. + +GNU Emacs is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
