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 | ||
795a2a94 GM |
37 | ** Emacs now supports the SVG image format through librsvg2. |
38 | ||
75f6af19 | 39 | ** If you set find-file-confirm-nonexistent-file to t, then C-x C-f |
0a963185 SM |
40 | requires confirmation before opening a non-existent file. |
41 | ||
6dadd99f NR |
42 | ** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a |
43 | Unix socket in a GNU/Linux console to talk to server, rather than faking events | |
44 | using the client program mev. This C level approach provides mouse | |
45 | highlighting, and help echoing in the minibuffer. | |
46 | ||
c2e8590b TTN |
47 | ** The new variable next-error-recenter specifies how next-error should |
48 | recenter the visited source file. Its value can be a number (for example, | |
49 | 0 for top line, -1 for bottom line), or nil for no recentering. | |
50 | ||
1f2e1c75 NR |
51 | ** The mode-line display a `@' if the default-directory for the current buffer |
52 | is on a remote machine, or a hyphen otherwise. | |
6c5d503f | 53 | |
62e3c31f SM |
54 | ** The new command balance-window-area balances windows both vertically |
55 | and horizontally. | |
d466e9fc SM |
56 | |
57 | ** The new command close-display-connection can be used to close a connection | |
58 | to a remote display, e.g. because the display is about to become unreachable. | |
6c5d503f MA |
59 | |
60 | ** The command shell prompts for the default directory, when it is | |
61 | called with a prefix, and the default directory is a remote file name. | |
62 | This is because some file name handler (like ange-ftp) are not able to | |
63 | run processes remotely. | |
6dadd99f | 64 | \f |
0bfd685e | 65 | * Startup Changes in Emacs 23.1 |
21f7b9d8 | 66 | |
56e1896b JL |
67 | ** New user option `initial-buffer-choice' specifies what to display |
68 | after starting Emacs: startup screen, *scratch* buffer, visiting a | |
69 | file or directory. | |

a151f82c SS |
77 | ** New command kill-matching-buffers kills buffers whose name matches a regexp. |
78 | ||
297b8ccd JL |
79 | ** Minibuffer changes: |
80 | ||
81 | *** isearch started in the minibuffer searches in the minibuffer history. | |
82 | Reverse isearch commands (C-r, C-M-r) search in previous minibuffer | |
83 | history elements, and forward isearch commands (C-s, C-M-s) search in | |
84 | next history elements. When the reverse search reaches the first history | |
85 | element, it wraps to the last history element, and the forward search | |
86 | wraps to the first history element. When the search is terminated, the | |
87 | history element containing the search string becomes the current. | |

90 | * New Modes and Packages in Emacs 23.1 | |
0091c67e | 91 | |
dcd6e8d7 | 92 | ** minibuffer-indicate-depth-mode shows the minibuffer depth in the prompt. |

95 | * Changes in Specialized Modes and Packages in Emacs 23.1 | |
61d244ca | 96 | |
813fb3fe SM |
97 | ** compilation-auto-jump-to-first-error tells `compile' to jump to |
98 | the first error encountered during compilations. | |
99 | ||
b649d2e4 SM |
100 | ** In the `copyright' package, you can specify your copyright holders's names. |
101 | Only copyright lines with holders matching copyright-names-regexp will be | |
102 | considered for update. | |
103 | ||
56dada42 | 104 | ** VC |
397c4757 DN |
105 | *** Clicking on the VC mode-line entry now pops the VC menu. |
106 | ||
107 | *** The VC mode-line entry now has a tooltip. | |
108 | ||
cb223bba DN |
109 | *** VC backends can provide extra menu entries to be added to the "Version Control" menu. |
110 | This can be used to add menu entries for backend specific functions. | |
111 | ||
5d503af9 SM |
112 | ** sgml-electric-tag-pair-mode lets you simultaneously edit matched tag pairs. |
113 | ||
2793c9bb RW |
114 | ** BibTeX mode: |
115 | ||
116 | *** New `bibtex-entry-format' options `whitespace', `braces', and | |
117 | `string', disabled by default. | |
118 | ||
119 | *** New variable `bibtex-cite-matcher-alist' contains rules to | |
120 | identify cited keys in BibTeX entries, used by `bibtex-find-crossref. | |
121 | ||
122 | *** Command `bibtex-url' now allows multiple URLs per entry. | |
123 | ||
cc213f24 MA |
124 | +++ |
125 | ** Tramp | |
126 | ||
127 | *** New connection methods. | |
128 | The new methods "plinkx", "plink2", "psftp", "sftp" and "fish" have | |
129 | been introduced. There are also new so-called gateway methods | |
130 | "tunnel" and "socks". | |
131 | ||
132 | *** Multihop syntax has been removed. | |
133 | The pseudo-method "multi" has been removed. Instead of, multi hops | |
134 | can be specified by the new variable `tramp-default-proxies-alist'. | |
135 | ||
136 | *** More default settings. | |
137 | Default values can be set via the variables `tramp-default-user', | |
138 | `tramp-default-user-alist' and `tramp-default-host'. | |
139 | ||
140 | *** Connection information is cached. | |
141 | In order to reduce connection setup, information about used | |
142 | connections are kept persistent in a file. The name of this file is | |
143 | defined in the variable `tramp-persistency-file-name'. | |
144 | ||
145 | *** Control of remote processes. | |
146 | Running processes on a remote host can be controlled by settings in | |
147 | `tramp-remote-path' and `tramp-remote-process-environment'. | |
148 | ||
149 | *** Success of remote copy is checked. | |
150 | When the variable `file-precious-flag' is set, the success of a remote | |
151 | file copy is checked via the file's checksum. | |
152 | ||
d15f7b68 GM |
153 | ** Miscellaneous programming mode changes |
154 | ||
155 | *** The variable `fortran-line-length' can change the fixed-form line-length. | |
156 | ||
157 | ** Miscellaneous | |
158 | ||
159 | *** comint-mode uses `start-file-process' now (see Lisp Changes). | |
cc213f24 MA |
160 | If `default-directory' is a remote file name, subprocesses are started |
161 | on the corresponding remote system. | |
162 | ||
d15f7b68 | 163 | *** C-x C-q in dired-mode now runs the command wdired-change-to-wdired-mode, |
40aa8257 JL |
164 | and C-x C-q in wdired-mode exits it with asking a question about |
165 | saving changes. | |

672f99b6 JR |
170 | --- |
171 | ** IPv6 is supported on MS-Windows. | |
172 | Emacs now supports IPv6 on Windows XP and later, and earlier versions | |
173 | of Windows with third party IPv6 stacks installed. Previously IPv6 was | |
174 | supported on other platforms, but not on Windows due to using the winsock | |
175 | 1.1 header file, even though Emacs was linking to the winsock 2 library. | |

186 | ** Non-breaking space now acts as whitespace. |
187 | ||
41bd52f7 | 188 | +++ |
8d371994 RS |
189 | ** In `condition-case', a handler can specify "let the debugger run first". |
190 | ||
191 | You do this by writing `debug' in the list of conditions to be handled, | |
192 | like this: | |
193 | ||
194 | (condition-case nil | |
195 | (foo bar) | |
196 | ((debug error) nil)) | |
197 | ||
0a963185 SM |
198 | ** The `require-match' argument to `completing-read' accepts a new value |
199 | `confirm-only'. | |
200 | ||
c69b0314 SM |
201 | +++ |
202 | ** The regexp form \(?<num>:<regexp>\) specifies the group number explicitly. | |
203 | ||
abf13a8b CY |
204 | +++ |
205 | ** New variable `user-emacs-directory'. | |
206 | Use this instead of "~/.emacs.d". | |
207 | ||
b2b387f9 MA |
208 | +++ |
209 | ** The new function `start-file-process is similar to `start-process', | |
210 | but obeys file handlers. The file handler is chosen based on | |
6dbe7eb4 MA |
211 | `default-directory'. The functions `start-file-process-shell-command' |
212 | and `process-file-shell-command' are also new; they call internally | |
213 | `start-file-process and `process-file', respectively. | |
b2b387f9 | 214 | |
64639e26 | 215 | +++ |
41bd52f7 MA |
216 | ** `file-remote-p' has new optional parameters IDENTIFICATION and CONNECTED. |
217 | IDENTIFICATION specifies which part of the remote identifier has to be | |
218 | returned. With CONNECTED passed non-nil, it is checked whether a | |
219 | remote connection has been established already. | |
64639e26 | 220 | |
45595a4f RS |
221 | ** The two new functions `looking-at-p' and `string-match-p' can do |
222 | the same matching as `looking-at' and `string-match' without changing | |
223 | the match data. | |
89835619 SM |
224 | |
225 | ** The interactive-form of a function can be added post-facto via the | |
226 | `interactive-form' symbol property. Mostly useful to add complex interactive | |
227 | forms to subroutines. | |
