  17 Temporary note:
  18  +++ indicates that the appropriate manual has already been updated.
  19  --- means no change in the manuals is called for.
  20 When you add a new item, please add it without either +++ or ---
  21 so we will look at it and add it to the manual.

  27 * Installation Changes in Emacs 23.1
  28
  29 ** The default X toolkit is now Gtk+, rather than Lucid.
  30
  31 ** configure now checks for libgif before libungif when searching for
  32 a GIF library.

  36
  37 ** If you set find-file-confirm-nonexistent-file to t, then C-x C-f
  38 requires confirmation before opening a non-existent file.
  39
  40 ** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a
  41 Unix socket in a GNU/Linux console to talk to server, rather than faking events
  42 using the client program mev.  This C level approach provides mouse
  43 highlighting, and help echoing in the minibuffer.
  44
  45 ** The new variable next-error-recenter specifies how next-error should
  46 recenter the visited source file.  Its value can be a number (for example,
  47 0 for top line, -1 for bottom line), or nil for no recentering.

  61 * New Modes and Packages in Emacs 23.1
  62
  63 ** css-mode to edit Cascading Style Sheets.
  64
  65 ** bibtex-style-mode helps you write BibTeX's *.bst files.
  66
  67 ** vera-mode to edit Vera files.
  68
  69 ** socks.el (which had been part of W3) is now part of Emacs.
  70
  71 ** minibuffer-indicate-depth-mode shows the minibuffer depth in the prompt.
  72
  73 \f
  74 * Changes in Specialized Modes and Packages in Emacs 23.1
  75
  76 ** compilation-auto-jump-to-first-error tells `compile' to jump to
  77 the first error encountered during compilations.
  78
  79 ** In the `copyright' package, you can specify your copyright holders's names.
  80 Only copyright lines with holders matching copyright-names-regexp will be
  81 considered for update.
  82
  83 ** VC
  84 *** VC backends can provide completion of revision names.
  85 *** VC has some support for Bazaar (bzr).
  86
  87 *** VC has some support for Mercurial (hg).
  88
  89 ** sgml-electric-tag-pair-mode lets you simultaneously edit matched tag pairs.
  90
  91 ** BibTeX mode:
  92
  93 *** New `bibtex-entry-format' options `whitespace', `braces', and
  94 `string', disabled by default.
  95
  96 *** New variable `bibtex-cite-matcher-alist' contains rules to
  97 identify cited keys in BibTeX entries, used by `bibtex-find-crossref.
  98
  99 *** Command `bibtex-url' now allows multiple URLs per entry.
 100
 101 +++
 102 ** Tramp
 103
 104 *** New connection methods.
 105 The new methods "plinkx", "plink2", "psftp", "sftp" and "fish" have
 106 been introduced.  There are also new so-called gateway methods
 107 "tunnel" and "socks".
 108
 109 *** Multihop syntax has been removed.
 110 The pseudo-method "multi" has been removed.  Instead of, multi hops
 111 can be specified by the new variable `tramp-default-proxies-alist'.
 112
 113 *** More default settings.
 114 Default values can be set via the variables `tramp-default-user',
 115 `tramp-default-user-alist' and `tramp-default-host'.
 116
 117 *** Connection information is cached.
 118 In order to reduce connection setup, information about used
 119 connections are kept persistent in a file.  The name of this file is
 120 defined in the variable `tramp-persistency-file-name'.
 121
 122 *** Control of remote processes.
 123 Running processes on a remote host can be controlled by settings in
 124 `tramp-remote-path' and `tramp-remote-process-environment'.
 125
 126 *** Success of remote copy is checked.
 127 When the variable `file-precious-flag' is set, the success of a remote
 128 file copy is checked via the file's checksum.
 129
 130 ** comint-mode uses `start-file-process' now (see Lisp Changes).
 131 If `default-directory' is a remote file name, subprocesses are started
 132 on the corresponding remote system.
 133
 134 \f
 135 * Changes in Emacs 23.1 on non-free operating systems
 136
 137 ---
 138 ** IPv6 is supported on MS-Windows.
 139 Emacs now supports IPv6 on Windows XP and later, and earlier versions
 140 of Windows with third party IPv6 stacks installed. Previously IPv6 was
 141 supported on other platforms, but not on Windows due to using the winsock
 142 1.1 header file, even though Emacs was linking to the winsock 2 library.
 143
 144 \f
 145 * Incompatible Lisp Changes in Emacs 23.1
 146
 147 +++
 148 ** The function `dired-call-process' has been removed.
 149
 150 \f
 151 * Lisp Changes in Emacs 23.1
 152
 153 +++
 154 ** In `condition-case', a handler can specify "let the debugger run first".
 155
 156 You do this by writing `debug' in the list of conditions to be handled,
 157 like this:
 158
 159     (condition-case nil
 160         (foo bar)
 161       ((debug error) nil))
 162
 163 ** The `require-match' argument to `completing-read' accepts a new value
 164 `confirm-only'.
 165
 166 +++
 167 ** The regexp form \(?<num>:<regexp>\) specifies the group number explicitly.
 168
 169 +++
 170 ** New variable `user-emacs-directory'.
 171 Use this instead of "~/.emacs.d".
 172
 173 +++
 174 ** The new function `image-refresh' refreshes all images associated
 175 with a given image specification.
 176
 177 +++
 178 ** The new function `start-file-process is similar to `start-process',
 179 but obeys file handlers.  The file handler is chosen based on
 180 `default-directory'.
 181
 182 +++
 183 ** `file-remote-p' has new optional parameters IDENTIFICATION and CONNECTED.
 184 IDENTIFICATION specifies which part of the remote identifier has to be
 185 returned.  With CONNECTED passed non-nil, it is checked whether a
 186 remote connection has been established already.
 187
 188 ** The two new functions `looking-at-p' and `string-match-p' can do
 189 the same matching as `looking-at' and `string-match' without changing
 190 the match data.
