1 Release notes for AUCTeX 12.3 with preview-latex
4 AUCTeX provides by far the most wide-spread and sophisticated
5 environment for editing LaTeX, TeX, ConTeXt and Texinfo documents with
6 Emacs. Combined with packages like RefTeX, flyspell and others it is
7 pretty much without peer as a comprehensive authoring solution for a
8 large variety of operating system platforms and TeX distributions. It
9 supports document-dependent completion and syntax highlighting, easily
10 accessible menus, jumping to error locations in the source file, a
11 number of editing shortcuts, intelligent indentation and filling of
12 text during entry, and WYSIWYG previews of graphical elements like
13 math formulas right in the Emacs source buffer, by virtue of its
14 preview-latex component.
16 One part of the preview-latex subsystem is the central `preview.sty'
17 file that is independently useful for a number of applications and is
18 available in unbundled form from CTAN.
20 AUCTeX needs volunteers in particular for non-programming tasks:
21 documentation writing, tutorials, translations, reference material,
22 sleuth work, testing.
24 New features and fixed bugs in this release
27 Support for 'PSTricks' is now PDF-oriented. AUCTeX no longer turns
28 off PDF mode for 'PSTricks' documents even without 'pst-pdf'. It
29 now sets up 'TeX-PDF-from-DVI' option so that PDF output is
30 generated when 'TeX-PDF-mode' is enabled (default). Users who want
31 DVI output should disable PDF mode explicitly by file local
32 variable, or customize 'TeX-PDF-mode' to 'nil'.
34 The function 'font-latex-update-font-lock' has been obsoleted in
35 order to fix 'bug#37945'. That function was used by several style
36 files in order to refresh fontification after adding new symbols or
37 verbatim constructs. It is better to call 'font-lock-flush' in the
38 former case and 'font-latex-set-syntactic-keywords' in the latter
39 case. The function 'font-latex-update-font-lock' still exists as a
40 no-op which only shows a warning explaining how to update font-lock
41 as mentioned above.
43 Math expression highlighting was improved. Highlighting for
44 documents with a lot of inline math expressions '$...$' won't get
45 scrambled now ('bug#33139').
47 There is small incompatibility due to this fix. When odd number of
48 dollar signs are in a comment, the subsequent lines are highlighted
49 as math until another '$' appears. You can insert a commented
50 dollar sign ('%$') at the next suitable end of line as a
53 In addition, it is no longer recommended to customize
54 'font-latex-math-environments'. Use 'texmathp-tex-commands'
57 AUCTeX tracks changes in LaTeX2e 2020-02-02 release. AUCTeX
58 supports the improvements to LaTeX font selection mechanism (NFSS).
59 New macros like '\textsw' or '\textulc' are added to font insertion
60 keyboard commands. See the section for inserting font specifiers
61 for details. Further, the entries in the menu LaTeX, Insert Font
62 are reorganized and adjusted accordingly.
64 Macros previously provided by 'textcomp.sty' are now part of LaTeX
65 kernel. AUCTeX tracks this change as well and support for the new
66 macro '\legacyoldstylenums' is added.
68 Insertion of environments in LaTeX documents (i.e. 'C-c C-e') was
69 improved. The former code had a few bugs, which sometimes resulted
70 in either spurious empty line or spurious comment prefix, or both,
71 especially when the region is active. Those bugs are now fixed.
73 More bugs fixed, other minor features implemented.
78 It is required that you use at least GNU Emacs 24.
80 The preview-latex subsystem requires image support.
82 You'll also need a working LaTeX installation and Ghostscript.
83 dvipng (version 1.4 or later), a very fast DVI converter, can be
84 used to speed up the conversion.
89 The easiest way for getting AUCTeX is installing it with GNU ELPA, see
90 <URL:https://elpa.gnu.org/packages/auctex.html> for more information.
91 Other download options are available at
92 <URL:https://ftp.gnu.org/gnu/auctex/>. At release time, we provide the
93 source tarball. You can also use versions of Emacs that already
94 include AUCTeX or a software package management system for your
95 operating system which provides you with the latest release.
97 A separate directory for each release contains some stuff from the
98 tarball, such as ChangeLog, printable manuals, and a reference sheet.
99 The download area is mirrored to the directory support/auctex on CTAN.

106 Future development and additional information
109 AUCTeX is proceeding as a GNU project with the long-term intent of
110 merging it into Emacs. For that reason, all new contributors need to
111 assign copyright to their contributions to the FSF (the usual
112 procedure for Emacs contributors). The same holds for past
113 contributors. The principal authors and maintainers have already done
114 so, but it would require a diligent and diplomatic volunteer to find
115 and ask the rest.
117 Current AUCTeX managers are Arash Esbati, Mosè Giordano, and Tassilo
118 Horn. Everybody is welcome to contribute to the project by reporting
119 bugs and suggesting improvements, but the most effective way of
120 helping AUCTeX development remains volunteering for tasks.
