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. | |

29 | ** The default X toolkit is now Gtk+, rather than Lucid. |
30 | ||
9d3cc9b2 GM |
31 | ** configure now checks for libgif before libungif when searching for |
32 | a GIF library. | |

35 | * Changes in Emacs 23.1 |
36 | ||
75f6af19 | 37 | ** If you set find-file-confirm-nonexistent-file to t, then C-x C-f |
0a963185 SM |
38 | requires confirmation before opening a non-existent file. |
39 | ||
6dadd99f NR |
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 | ||
c2e8590b TTN |
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. | |

a151f82c SS |
58 | ** New command kill-matching-buffers kills buffers whose name matches a regexp. |
59 | ||
297b8ccd JL |
60 | ** Minibuffer changes: |
61 | ||
62 | *** isearch started in the minibuffer searches in the minibuffer history. | |
63 | Reverse isearch commands (C-r, C-M-r) search in previous minibuffer | |
64 | history elements, and forward isearch commands (C-s, C-M-s) search in | |
65 | next history elements. When the reverse search reaches the first history | |
66 | element, it wraps to the last history element, and the forward search | |
67 | wraps to the first history element. When the search is terminated, the | |
68 | history element containing the search string becomes the current. | |

73 | ** css-mode to edit Cascading Style Sheets. |
74 | ||
ede96990 | 75 | ** bibtex-style-mode helps you write BibTeX's *.bst files. |
7253ac49 | 76 | |
37d4643c DN |
77 | ** vera-mode to edit Vera files. |
78 | ||
dcd6e8d7 KS |
79 | ** socks.el (which had been part of W3) is now part of Emacs. |
80 | ||
81 | ** minibuffer-indicate-depth-mode shows the minibuffer depth in the prompt. | |

84 | * Changes in Specialized Modes and Packages in Emacs 23.1 | |
61d244ca | 85 | |
813fb3fe SM |
86 | ** compilation-auto-jump-to-first-error tells `compile' to jump to |
87 | the first error encountered during compilations. | |
88 | ||
b649d2e4 SM |
89 | ** In the `copyright' package, you can specify your copyright holders's names. |
90 | Only copyright lines with holders matching copyright-names-regexp will be | |
91 | considered for update. | |
92 | ||
56dada42 SM |
93 | ** VC |
94 | *** VC backends can provide completion of revision names. | |
95 | *** VC has some support for Bazaar (bzr). | |
d3cce191 | 96 | |
56dada42 | 97 | *** VC has some support for Mercurial (hg). |
61223448 | 98 | |
5d503af9 SM |
99 | ** sgml-electric-tag-pair-mode lets you simultaneously edit matched tag pairs. |
100 | ||
2793c9bb RW |
101 | ** BibTeX mode: |
102 | ||
103 | *** New `bibtex-entry-format' options `whitespace', `braces', and | |
104 | `string', disabled by default. | |
105 | ||
106 | *** New variable `bibtex-cite-matcher-alist' contains rules to | |
107 | identify cited keys in BibTeX entries, used by `bibtex-find-crossref. | |
108 | ||
109 | *** Command `bibtex-url' now allows multiple URLs per entry. | |
110 | ||

111 | +++ |
112 | ** Tramp | |
113 | ||
114 | *** New connection methods. | |
115 | The new methods "plinkx", "plink2", "psftp", "sftp" and "fish" have | |
116 | been introduced. There are also new so-called gateway methods | |
117 | "tunnel" and "socks". | |
118 | ||
119 | *** Multihop syntax has been removed. | |
120 | The pseudo-method "multi" has been removed. Instead of, multi hops | |
121 | can be specified by the new variable `tramp-default-proxies-alist'. | |
122 | ||
123 | *** More default settings. | |
124 | Default values can be set via the variables `tramp-default-user', | |
125 | `tramp-default-user-alist' and `tramp-default-host'. | |
126 | ||
127 | *** Connection information is cached. | |
128 | In order to reduce connection setup, information about used | |
129 | connections are kept persistent in a file. The name of this file is | |
130 | defined in the variable `tramp-persistency-file-name'. | |
131 | ||
132 | *** Control of remote processes. | |
133 | Running processes on a remote host can be controlled by settings in | |
134 | `tramp-remote-path' and `tramp-remote-process-environment'. | |
135 | ||
136 | *** Success of remote copy is checked. | |
137 | When the variable `file-precious-flag' is set, the success of a remote | |
138 | file copy is checked via the file's checksum. | |
139 | ||
140 | ** comint-mode uses `start-file-process' now (see Lisp Changes). | |
141 | If `default-directory' is a remote file name, subprocesses are started | |
142 | on the corresponding remote system. | |

145 | * Changes in Emacs 23.1 on non-free operating systems | |
8ab314f9 | 146 | |
672f99b6 JR |
147 | --- |
148 | ** IPv6 is supported on MS-Windows. | |
149 | Emacs now supports IPv6 on Windows XP and later, and earlier versions | |
150 | of Windows with third party IPv6 stacks installed. Previously IPv6 was | |
151 | supported on other platforms, but not on Windows due to using the winsock | |
152 | 1.1 header file, even though Emacs was linking to the winsock 2 library. | |

8d371994 RS |
164 | ** In `condition-case', a handler can specify "let the debugger run first". |
165 | ||
166 | You do this by writing `debug' in the list of conditions to be handled, | |
167 | like this: | |
168 | ||
169 | (condition-case nil | |
170 | (foo bar) | |
171 | ((debug error) nil)) | |
172 | ||
0a963185 SM |
173 | ** The `require-match' argument to `completing-read' accepts a new value |
174 | `confirm-only'. | |
175 | ||
c69b0314 SM |
176 | +++ |
177 | ** The regexp form \(?<num>:<regexp>\) specifies the group number explicitly. | |
178 | ||
abf13a8b CY |
179 | +++ |
180 | ** New variable `user-emacs-directory'. | |
181 | Use this instead of "~/.emacs.d". | |
182 | ||
14a6c6ab CY |
183 | +++ |
184 | ** The new function `image-refresh' refreshes all images associated | |
185 | with a given image specification. | |
186 | ||
b2b387f9 MA |
187 | +++ |
188 | ** The new function `start-file-process is similar to `start-process', | |
189 | but obeys file handlers. The file handler is chosen based on | |
190 | `default-directory'. | |
191 | ||
64639e26 | 192 | +++ |
41bd52f7 MA |
193 | ** `file-remote-p' has new optional parameters IDENTIFICATION and CONNECTED. |
194 | IDENTIFICATION specifies which part of the remote identifier has to be | |
195 | returned. With CONNECTED passed non-nil, it is checked whether a | |
196 | remote connection has been established already. | |
64639e26 | 197 | |
45595a4f RS |
198 | ** The two new functions `looking-at-p' and `string-match-p' can do |
199 | the same matching as `looking-at' and `string-match' without changing | |
200 | the match data. | |
