- Update to 12.3
* Support for 'PSTricks' is now PDF-oriented. AUCTeX no longer turns
off PDF mode for 'PSTricks' documents even without 'pst-pdf'. It
now sets up 'TeX-PDF-from-DVI' option so that PDF output is
generated when 'TeX-PDF-mode' is enabled (default). Users who want
DVI output should disable PDF mode explicitly by file local
variable, or customize 'TeX-PDF-mode' to 'nil'.
* The function 'font-latex-update-font-lock' has been obsoleted in
order to fix 'bug#37945'. That function was used by several style
files in order to refresh fontification after adding new symbols or
verbatim constructs. It is better to call 'font-lock-flush' in the
former case and 'font-latex-set-syntactic-keywords' in the latter
case. The function 'font-latex-update-font-lock' still exists as a
no-op which only shows a warning explaining how to update font-lock
as mentioned above.
* Math expression highlighting was improved. Highlighting for
documents with a lot of inline math expressions '$...$' won't get
scrambled now ('bug#33139').
* AUCTeX tracks changes in LaTeX2e 2020-02-02 release. AUCTeX
supports the improvements to LaTeX font selection mechanism (NFSS).
New macros like '\textsw' or '\textulc' are added to font insertion
keyboard commands. See the section for inserting font specifiers
for details. Further, the entries in the menu LaTeX, Insert Font
are reorganized and adjusted accordingly.
* Insertion of environments in LaTeX documents (i.e. 'C-c C-e') was
improved. The former code had a few bugs, which sometimes resulted
in either spurious empty line or spurious comment prefix, or both,
especially when the region is active. Those bugs are now fixed.
* More bugs fixed, other minor features implemented.
