  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.
  33
  34 \f
  35 * Changes in Emacs 23.1
  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.

  56 * Editing Changes in Emacs 23.1
  57
  58 ** New command kill-matching-buffers kills buffers whose name matches a regexp.
  59
  60 ** Bookmark commands live under prefix C-x p now, instead of C-x r.  Some of
  61    the individual bindings have changed; do C-x p C-h for details.
  62
  63 \f
  64 * New Modes and Packages in Emacs 23.1
  65
  66 ** css-mode to edit Cascading Style Sheets.
  67
  68 ** bibtex-style-mode helps you write BibTeX's *.bst files.
  69
  70 ** vera-mode to edit Vera files.
  71
  72 ** socks.el (which had been part of W3) is now part of Emacs.
  73
  74 ** minibuffer-indicate-depth-mode shows the minibuffer depth in the prompt.
  75
  76 \f
  77 * Changes in Specialized Modes and Packages in Emacs 23.1
  78
  79 ** compilation-auto-jump-to-first-error tells `compile' to jump to
  80 the first error encountered during compilations.
  81
  82 ** In the `copyright' package, you can specify your copyright holders's names.
  83 Only copyright lines with holders matching copyright-names-regexp will be
  84 considered for update.
  85
  86 ** VC
  87 *** VC backends can provide completion of revision names.
  88 *** VC has some support for Bazaar (bzr).
  89
  90 *** VC has some support for Mercurial (hg).
  91
  92 ** sgml-electric-tag-pair-mode lets you simultaneously edit matched tag pairs.
  93
  94 ** BibTeX mode:
  95
  96 *** New `bibtex-entry-format' options `whitespace', `braces', and
  97 `string', disabled by default.
  98
  99 *** New variable `bibtex-cite-matcher-alist' contains rules to
 100 identify cited keys in BibTeX entries, used by `bibtex-find-crossref.
 101
 102 *** Command `bibtex-url' now allows multiple URLs per entry.
 103
 104 +++
 105 ** Tramp
 106
 107 *** New connection methods.
 108 The new methods "plinkx", "plink2", "psftp", "sftp" and "fish" have
 109 been introduced.  There are also new so-called gateway methods
 110 "tunnel" and "socks".
 111
 112 *** Multihop syntax has been removed.
 113 The pseudo-method "multi" has been removed.  Instead of, multi hops
 114 can be specified by the new variable `tramp-default-proxies-alist'.
 115
 116 *** More default settings.
 117 Default values can be set via the variables `tramp-default-user',
 118 `tramp-default-user-alist' and `tramp-default-host'.
 119
 120 *** Connection information is cached.
 121 In order to reduce connection setup, information about used
 122 connections are kept persistent in a file.  The name of this file is
 123 defined in the variable `tramp-persistency-file-name'.
 124
 125 *** Control of remote processes.
 126 Running processes on a remote host can be controlled by settings in
 127 `tramp-remote-path' and `tramp-remote-process-environment'.
 128
 129 *** Success of remote copy is checked.
 130 When the variable `file-precious-flag' is set, the success of a remote
 131 file copy is checked via the file's checksum.
 132
 133 ** comint-mode uses `start-file-process' now (see Lisp Changes).
 134 If `default-directory' is a remote file name, subprocesses are started
 135 on the corresponding remote system.

 138 * Changes in Emacs 23.1 on non-free operating systems
 139
 140 \f
 141 * Incompatible Lisp Changes in Emacs 23.1
 142
 143 +++
 144 ** The function `dired-call-process' has been removed.
 145
 146 \f
 147 * Lisp Changes in Emacs 23.1
 148
 149 ** The `require-match' argument to `completing-read' accepts a new value
 150 `confirm-only'.
 151
 152 +++
 153 ** The regexp form \(?<num>:<regexp>\) specifies the group number explicitly.
 154
 155 +++
 156 ** New variable `user-emacs-directory'.
 157 Use this instead of "~/.emacs.d".
 158
 159 +++
 160 ** The new function `image-refresh' refreshes all images associated
 161 with a given image specification.
 162
 163 +++
 164 ** The new function `start-file-process is similar to `start-process',
 165 but obeys file handlers.  The file handler is chosen based on
 166 `default-directory'.
 167
 168 +++
 169 ** `file-remote-p' has a new optional parameter CONNECTED.
 170 With this paramter passed non-nil, it is checked whether a remote
 171 connection has been established already.
 172
 173 ** The two new functions `looking-at-p' and `string-match-p' can do
 174 the same matching as `looking-at' and `string-match' without changing
 175 the match data.
