12 *** IMPORTANT NEWS FOR ALL AUTHORS OF TEXINFO MANUALS ***
14 As of version 4.2, Texinfo has a new command @copying to define the
15 copyright and copying permissions for a manual. It's important to
16 switch to using it as soon as possible (as in your next release),
17 because the historical method of doing copyright permissions using
18 @ifinfo failed to output copyright information in the HTML (or XML)
19 formats. The manual has detailed explanations and examples. For
20 convenience, here's a url to one of the relevant sections:
21 http://texinfo.org/manual/Document-Permissions.html
27 . new command @copying to define copying permissions. See above.
28 . new conditionals @ifplaintext, @ifnotplaintext for the plain text
29 (--no-headers) output format.
30 . new command @\ to produce literal \ inside @math, since \ by itself
33 . emit accesskey attributes for keyboard shortcuts to menu items.
34 . @{even,every,odd}{footing,header} are ignored by makeinfo now, so
35 they no longer need to be enclosed in @iftex.
37 . bug fix for pdf-format table of contents.
39 . bug fixes for -R (--raw-escapes).
40 . --help shows short option names.
42 . the doc.c, funs.h, and key.c files in info/ are no longer generated
43 at make time, to appease Automake's make distcheck.
44 . gettext 0.11.1, autoconf 2.53, automake 1.6 (with install-info kludge).
50 . new commands @verbatim and @verb for printing verbatim inserts.
51 . new command @verbatiminclude for verbatim include of files.
52 . new environment @documentdescription for defining the HTML description.
53 . new command @afivepaper for the A5 paper size.
55 . supports xml and docbook output.
56 . supports HTML splitting by node, which is now the default.
57 . new option --split-size to control maximum size of split info files.
59 . user-specified key bindings supported.
60 . ANSI escape sequences (as produced by groff) removed from man output
61 by default; use --raw-escapes to let them through if your terminal
64 . @math implies @tex, so all the usual plain TeX math is supported.
65 . smaller fonts for @smallexample, in all page sizes.
66 . improvements in the PDF support.
68 . new option -o to explicitly specify output filename.
70 . switch to GNU Free Documentation License (http://www.gnu.org/copyleft/).
71 . update to GNU gettext 0.11, autoconf 2.52, and automake 1.5.
72 . Danish, Swedish, and Hebrew message translations.
75 4.0 (28 September 1999)
77 . New command @anchor for cross references to arbitrary points.
78 . New commands @documentlanguage sets the main document language,
79 and @documentencoding sets the document input encoding (although not
80 much is done yet with either).
81 . New command @pagesizes allows limited control of text area for typesetting.
82 . New command @acronym for abbreviations in all caps, such as `NASA'.
83 . New command @alias for simple command aliases.
84 . New command @definfoenclose for better control of info output.
85 . New commands @deftypeivar for typed instance variables of a class
86 and @deftypeop for typed operations of a class.
87 . New command @novalidate suppresses cross-reference checking and (in
88 TeX) auxiliary file creation.
89 . New commands @setcontentsaftertitlepage and
90 @setshortcontentsaftertitlepage to force printing the table of
91 contents after @end titlepage. Also, @contents and @shortcontents
92 themselves can now appear at the beginning of the document as
94 . New markup commands: @env (for environment variables), @command (for
95 command names), @option (for command-line options).
96 . New commands @smallformat and @smalldisplay, a la @smallexample.
97 . New command @exampleindent to set indentation of example-like
98 environments a la @paragraphindent.
99 . @uref takes an optional third argument of text to show instead of
100 (rather than in addition to) the url for info and dvi output.
101 . @footnote works in an @item for a @table.
103 . latest version always at ftp://ftp.gnu.org/gnu/texinfo.tex (and mirrors).
105 . implements @paragraphindent (except asis).
106 . @emph and @i use true italic type (cmti) instead of slanted (cmsl).
107 . implements pdf output when run with pdftex.
108 . better support for internationalization via txi-??.tex files.
109 . footnotes now set in a smaller point size.
111 . supports HTML output with the --html option.
112 . implication of --html: @top nodes should be wrapped in @ifnottex
113 rather than @ifinfo. @ifinfo conditionals are not expanded with --html.
114 . new option --number-sections to output chapter/section numbers.
115 . dashes and quotes are not treated specially in node names.
116 . new option --commands-in-node-names to allow @-commands in node names.
117 (Not implemented in TeX, and most likely never will be.)
118 . @emph output uses _underscores_.
119 . @image looks for .png files before .jpg.
120 . only output `Making ... file' line when verbose.
121 . allow -v as synonym for --verbose.
122 . new command line options to specify which conditionals to process
123 (but --iftex is not fully implemented).
124 . warns if @var contains any of ,[]().
125 . @quote-arg implicitly done for all one-argument macros, so commas in
126 the argument text are allowed.
127 . \\ required in macro body to get single \, no other `escapes' defined.
129 . ISO Latin 1 characters are displayed and input as-is by default.
130 . new option --vi-keys to enable vi-like and less-like key bindings.
131 . new command S does case-sensitive searching.
132 . new commands C-x n and C-x N repeat last search, respectively, in the
133 same and in reverse direction, without prompting for the string. These
134 commands are bound to n and N under --vi-keys, like in Less.
135 . new command G menu1 menu2 ... searches for menu items from (dir),
136 as allowed on the command line.
137 . new command O (capital o, not zero) goes directly to the node that
138 describes command-line options.
139 . new command-line option --show-options causes the node which
140 describes command-line options to be the first node displayed.
141 . M-prior and M-DEL do new command info-scroll-other-window-backward.
142 . / searches like s does.
143 . If the search string includes upper-case letters, in both incremental
144 and non-incremental search, the search is case-sensitive.
145 . S searches case-sensitively even if the search string is all
147 . - makes the argument negative (so e.g. `- /' searches backward).
148 . l restores point in the window returned to.
149 . SPC/DEL do not move outside the current document.
150 . foo.info is found before foo.
151 . `info foo --index-search=bar' now searches for bar in foo's index.
152 . support for files compressed with bzip2.
154 . handles gzipped dir files.
155 . sort entries into alphabetical order.
156 . install direntries only in preceding dircategory, not in all.
157 . --delete does not require the info file to exist.
158 . --delete can handle XEmacs-style dir entries.
160 . bug fixed: now uses only the @iftex and @tex parts of the source.
161 . process LaTeX source as well as Texinfo source.
162 . output PDF (using pdftex) with new option --pdf.
163 . handles --OPTION=ARG style of command line arguments.
164 . new option --batch for progress reports but no interaction.
165 . new option --clean to remove all auxiliary files.
166 . new option --quiet for silence (unless there are errors).
167 . new option -I for specifying directories for @include to search.
168 . handles LaTeX files (running BibTeX etc.).
169 * Fixes to util/gen-dir-node and util/fix-info-dir (formerly util/update-info).
171 . Man pages included.
172 . Czech and Norwegian message translations.
173 . Various translations for texinfo.tex fixed words included.
178 * Elisp files removed, since they are only usefully distributed with Emacs.
179 * Restore inclusion of compile-time $(infodir) to INFOPATH.
180 * install-info creates a proper dir file.
181 * Various portability fixes.
186 - @uref to make a reference to a url; @url now only indicates such.
187 - @image to include graphics (epsf for TeX).
188 - @deftypemethod and @deftypemethodx to document methods in strongly
189 typed object-oriented languages, such as C++.
190 - @html for raw HTML.
191 - @ifnothtml @ifnotinfo @ifnottex for more precise conditionals.
192 - @kbdinputstyle to control when @kbd uses the slanted typewriter font.
193 - @email takes second optional argument.
194 * texinfo.tex reads texinfo.cnf (if present) for site-wide TeX
195 configuration; for example, A4 paper sizes.
197 - arrow keys supported.
198 - trailing : in INFOPATH appends default path.
199 - new option --index-search for online help support.
201 - output files removed if errors unless (new option) --force.
202 - new option -P to prepend to search path.
203 - macro expansion file can be standard output.
204 * install-info creates a new dir file if necessary.
205 * update-info script to create a dir file from all info files.
206 * Elisp: texnfo-tex.el and detexinfo.el removed from the distribution;
207 - texnfo-tex features are now part of standard TeX & Texinfo packages;
208 - makeinfo --no-headers does a better job than detexinfo.el.
210 - Updates, revisions, corrections in the manual.
211 - makeinfo.texi removed, as it was a copy of what was in texinfo.texi.
212 * gettext support in sources, French and German translations included.
213 * info man page removed; use the Texinfo manual.
214 * Automake used, other portability fixes.
221 - Give a suppressible (with --no-validate) error for references
223 - Keep track of multitable output correctly for split files; this
224 caused nodes after the first multitable to be ``undefined''.
226 - Rename --infodir option to --info-dir.
227 - More robust error checking to avoid various crashes.
228 * configure: Include replacements for memcpy and memmove functions in
229 the distribution, in case they are missing.
232 3.8 (30 September 1996)
233 * Define and/or document new and/or previously existing commands:

246 @headings singleafter/doubleafter (change heading style after current page)
250 @shorttitlepage (simple title pages)
251 @detailmenu...@end detailmenu (help makeinfo parse master menus)
252 * Makeinfo prefers an input file named `foo.texinfo' or `foo.texi' or
253 `foo.txinfo' to just `foo' (the latter most likely being an executable).
254 * Makeinfo implements @. @! @? correctly, as end-of-sentence punctuation.
255 * @key marks its argument with a lozenge in TeX and <...> in Info.
256 * TeX output has substantially decreased interline spacing and other

315 Just bug fixes, see ChangeLog for full details.
318 3.0: first release of Texinfo version 2, with many new commands.
322 Here is the separate NEWS for old releases of Info:
324 Version 2.11, Sat Apr 1 09:15:21 1995
326 Changes since 2.7 beta:
328 Although the basic code remains the same, there are numerous nits
329 fixed, including some display bugs, and a memory leak. Some changes
330 that have taken place with larger impact include the way in which the
331 (dir) node is built; I have added in support for "localdir"
332 directories among other things. Info files may be stored in
333 compressed formats, and in their own subdirectories; menu items which
334 do not explicitly name the node to which they are attached have the
335 menu item name looked up as an Info file if it is not found within the
336 current document. This means that the menu item:
338 * Info:: The Info documentation reader.
340 in (dir) refers to the info node "(info)Top".
342 Please see the ChangeLog and documentation for details on other
345 Version 2.7 beta, Wed Dec 30 02:02:38 1992
346 Version 2.6 beta, Tue Dec 22 03:58:07 1992
347 Version 2.5 beta, Tue Dec 8 14:50:35 1992
348 Version 2.4 beta, Sat Nov 28 14:34:02 1992
349 Version 2.3 beta, Fri Nov 27 01:04:13 1992
350 Version 2.2 beta, Tue Nov 24 09:36:08 1992
351 Version 2.1 beta, Tue Nov 17 23:29:36 1992
353 Changes since 2.5 beta:
355 Note that versions 2.6 and 2.7 Beta were only released to a select group.
357 * "info-" removed from the front of M-x commands.
359 * Automatic footnote display. When you enter a node which contains
360 footnotes, and the variable "automatic-footnotes" is "On", Info pops
361 up a window containing the footnotes. Likewise, when you leave that
362 node, the window containing the footnotes goes away.
364 * Cleaner built in documentation, and documentation functions.
367 o `M-x describe-variable' to read a variable's documenation
368 o `M-x describe-key' to find out what a particular keystroke does.
369 o `M-x describe-function' to read a function's documentation.
370 o `M-x where-is' to find out what keys invoke a particular function.
372 * Info can "tile" the displayed windows (via "M-x tile-windows"). If
373 the variable "automatic-tiling" is "On", then splitting a window or
374 deleting a window causes the remaining windows to be retiled.
376 * You can save every keystroke you type in a "dribble file" by using the
377 `--dribble FILENAME' option. You can initially read keystrokes from an
378 alternate input stream with `--restore FILENAME', or by redirecting
379 input on the command line `info < old-dribble'.
381 * New behaviour of menu items. If the label is the same as the
382 target node name, and the node couldn't be found in the current file,
383 treat the label as a file name. For example, a menu entry in "DIR"
386 * Emacs:: Cool text-editor.
388 Info would not find the node "(dir)Emacs", so just plain "(emacs)"
391 * New variable "ISO-Latin" allows you to use European machines with
392 8-bit character sets.
394 * Cleanups in echo area reading, and redisplay. Cleanups in handling the
395 window which shows possible completions.
397 * Info can now read files that have been compressed. An array in filesys.c
398 maps extensions to programs that can decompress stdin, and write the results
399 to stdout. Currently, ".Z"/uncompress, ".z"/gunzip, and ".Y"/unyabba are
400 supported. The modeline for a compressed file shows "zz" in it.
402 * There is a new variable "gc-compressed-files" which, if non-zero, says
403 it is okay to reclaim the file buffer space allocated to a file which
404 was compressed, if, and only if, that file's contents do not appear in
407 * New file `nodemenu.c' implements a few functions for manipulating
408 previously visited nodes. `C-x C-b' (list-visited-nodes) produces a
409 menu of the nodes that could be reached by info-history-node in some
410 window. `C-x b' (select-visited-node) is similar, but reads one of
411 the node names with completion.
413 * Keystroke `M-r' (move_to_screen_line) allows the user to place the cursor at
414 the start of a specific screen line. Without a numeric argument, place the
415 cursor on the center line; with an arg, place the cursor on that line.
417 * Interruptible display implemented. Basic display speedups and hacks.
418 * The message "*** Tags Out of Date ***" now means what it says.
419 * Index searching with `,' (info-index-next) has been improved.
420 * When scrolling with C-v, C-M-v, or M-v, only "Page Only" scrolling
423 * Continous scrolling (along with `]' (info-global-next) and `['
424 (info-global-prev) works better. `]' and `[' accept numeric
425 arguments, moving that many nodes in that case.
427 * `C-x w' (info-toggle-wrap) controls how lines wider than the width
428 of the screen are displayed. If a line is too long, a `$' is
429 displayed in the rightmost column of the window.
431 * There are some new variables for controlling the behaviour of Info
432 interactively. The current list of variables is as follows:
434 Variable Name Default Value Description
435 ------------- ------------- -----------
436 `automatic-footnotes' On When "On", footnotes appear and
437 disappear automatically.
439 `automatic-tiling' Off When "On", creating of deleting a
440 window resizes other windows.
442 `visible-bell' Off If non-zero, try to use a visible bell.
444 `errors-ring-bell' On If non-zero, errors cause a ring.
446 `show-index-match' On If non-zero, the portion of the string
447 matched is highlighted by changing its
450 `scroll-behaviour' Continuous One of "Continuous", "Next Only", or
451 "Page Only". "Page Only" prevents you from
452 scrolling past the bottom or top of a node.
453 "Next Only" causes the Next or Prev node to
454 be selected when you scroll past the bottom
455 or top of a node. "Continous" moves
456 linearly through the files hierchichal
459 `scroll-step' 0 Controls how scrolling is done for you when
460 the cursor moves out of the current window.
461 Non-zero means it is the number of lines
462 you would like the screen to shift. A
463 value of 0 means to center the line
464 containing the cursor in the window.
466 `gc-compressed-files' Off If non-zero means it is okay to reclaim the
467 file buffer space allocated to a file which
468 was compressed, if, and only if, that
469 file's contents do not appear in the node
472 `ISO-Latin' Off Non-zero means that you are using an ISO
473 Latin character set. By default, standard
474 ASCII characters are assumed.
475 ________________________________________
