A new function TeX-doc for accessing docs on C-c ?. New "Clean" and "Clean All" commands for intermediate and output files. pdfsync support (forward search in PDF files). LaTeX comes with its own toolbar enabled by default. Some bugs have been fixed.
Processing of errors and warnings resulting from processor invocations was improved. In order to make typing sub- and superscript in math constructs more convenient, automatic brace insertion upon typing '^' or '_' can be activated. French quotation marks as supported by the 'frenchb' or 'francais' babel options can now be entered by simply typing ". Completion support for options of some LaTeX packages was added. There are various bugfixes.
The most important feature is the inclusion of the preview-latex subsystem, previously available separately. The installation procedures now also install startup files as part of the process (those had to be copied manually previously). You are advised to remove previous installations of AUCTeX and preview-latex before starting the installation procedure. A standard installation from an unmodified tarball no longer requires Makeinfo or Perl. Several minor feature enhancements have been added.
This release fixes erroneous insertion of trailing whitespace during filling, unwanted display of the *Compile-Log* buffer when the first LaTeX file in an Emacs session is loaded, and 'File mode specification error: (error "Variable binding depth exceeds max-specpdl-size")' if an outdated Emacspeak package is installed. But since both Emacs and XEmacs contain a correct version of `regexp-opt.el', simply removing any such file within your copy of Emacspeak appears safer.
This is mainly a bugfix release for XEmacs, as well as performance issues with font locking and filling, and other issues like broken fontification of verbatim environments. Font locking can now be customized to a great extent, and support for URLs, listings, jurabib, and csquotes was added. The parser now understands additional common commands like \DeclareRobustCommand. Two new sections were added to the manual: "Quick Start" for beginners, and "Font Locking" describing syntax highlighting in AUCTeX and its customization options.
