+Changes and New Features in AUCTeX
+**********************************
+
+News in 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').
+
+ There is small incompatibility due to this fix. When odd number of
+ dollar signs are in a comment, the subsequent lines are highlighted
+ as math until another '$' appears. You can insert a commented
+ dollar sign ('%$') at the next suitable end of line as a
+ workaround.
+
+ In addition, it is no longer recommended to customize
+ 'font-latex-math-environments'. Use 'texmathp-tex-commands'
+ instead.
+
+ * 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.
+
+ Macros previously provided by 'textcomp.sty' are now part of LaTeX
+ kernel. AUCTeX tracks this change as well and support for the new
+ macro '\legacyoldstylenums' is added.
+
+ * 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.
+
+News in 12.2
+============
+
+ * AUCTeX reflects the changes in LaTeX2e 2019-10-01 release.
+ 'filecontents' environment now takes an optional argument and can
+ be used anywhere in a document. The macros '\Ref' and
+ '\labelformat' are moved from 'varioref.sty' to LaTeX kernel.
+ amsmath has a new macro '\overunderset'.
+
+ * A new method is implemented in preview-latex to adjust the
+ foreground colors of generated images to those of Emacs, when the
+ LaTeX command produces PDF. The traditional method became invalid
+ because of the change introduced in Ghostscript 9.27.
+ Unfortunately, the new method doesn't work due to a bug in
+ Ghostscript 9.27 and is valid only for Ghostscript > 9.27. There
+ is also a fallback method for gs 9.27 users which displays plain
+ "black on white" images. For successful function of preview-latex,
+ the users are encouraged to set up the new user option
+ 'preview-pdf-color-adjust-method' to choose appropriate option
+ among the three: new, traditional and fallback method.
+
+ * AUCTeX has support for the Flymake package in Emacs 26 or newer.
+ To enable, call 'M-x flymake-mode RET' or add this to your '.emacs'
+ file:
+ (add-hook 'LaTeX-mode-hook #'flymake-mode)
+
+ * The way the option 'TeX-record-buffer' is used was corrected. It
+ was used in just the opposite way as the document says. Erase the
+ customization if you have customized this option since it now acts
+ in reverse to your expectation.
+
+ * A former customize option 'japanese-TeX-command-list' is removed.
+ Use 'japanese-TeX-engine-default', or if it's really necessary,
+ customize 'TeX-command-list' directly if the task which the option
+ used to carry is required.
+
+ * Support for standard LaTeX without e-TeX extension is now very
+ limited. It doesn't work if raw TeX code is put on the command
+ line to invoke latex command. It also fails for region compilation
+ ('C-c C-r' and so on) with documents of non-ascii file name. In
+ addition, it no longer works with preview-latex. We consider this
+ incompatibility is permissible because e-TeX extension is enabled
+ for standard LaTeX by default long ago. LaTeX variants such as
+ XeLaTeX and LuaLaTeX are not affected.
+
+ * Key binds in Texinfo mode are improved. Typing '$', '^', '_' and
+ '\' now just self-inserts without pointless side effects in Texinfo
+ mode.
+
+ In addition, the option 'TeX-electric-escape' is now effective in
+ Texinfo mode. When it is enabled, typing '@' will invoke
+ 'TeX-electric-macro' offering completion in similar style with
+ other TeX modes of AUCTeX.
+
+ * Fontification support for 'biblatex' package is improved and
+ updated to macros provided by package version 3.12. For qualified
+ lists, at least 2 mandatory arguments are fontified.
+
+ * Support for column specifiers 'w' and 'W' provided by 'array'
+ package is added to 'array.el'. The correct counting of columns
+ only works when the 'align' parameter is enclosed in braces, e.g.,
+ 'w{l}{3cm}'. The short version 'wl{3cm}' is not supported.
+
+ * Entries for 'PDF Tools' are added in
+ 'TeX-view-program-list-builtin' for Windows and macOS. This viewer
+ can be configured under these operating systems with an entry like
+ this in an init file:
+ (setq TeX-view-program-selection '((output-pdf "PDF Tools")))
+
+ * Several other bugs were fixed, many minor features were added.
+
+News in 12.1
+============
+
+ * AUCTeX now requires GNU Emacs 24 or higher. Support for XEmacs has
+ been dropped.
+
+ * Besides the change in the supported version of Emacs, there has
+ been no functional change in this release, which is equivalent to
+ version 11.92.
+
+News in 11.92
+=============
+
+ * preview-latex is compatible with Ghostscript 9.22 where the
+ operator '.runandhide' is removed. All occurrences of
+ '.runandhide' in preview-latex are replaced by alternative code
+ making it work with Ghostscript 9.22 again.
+
+ * AUCTeX has a new customize option
+ 'TeX-math-input-method-off-regexp'. When you begin to input a math
+ formula, the current input method is turned off if its name matches
+ this regular expression.
+
+ In fact this variable was introduced long before, but has not been
+ documented in info files nor turned into a customize option with
+ 'defcustom' until this release.
+
+ * The window system focus is pulled back to Emacs when viewing with
+ evince-compatible viewers if a new customize option
+ 'TeX-view-evince-keep-focus' is non-nil.
+
+ * The usual dose of bug fixes was administered.
+
+News in 11.91
+=============
+
+ * Now AUCTeX has a logo. The LaTeX code to create it is available in
+ the 'etc/' directory of the package.
+
+ * Add support for 'upmendex', an extension of 'makeindex' capable of
+ sorting indexes by unicode based ICU.
+
+ * Fix preview-latex to interact correctly with Japanese LaTeX. The
+ parsing routine was made robust not to be confused by the 7-bit
+ encoding of Japanese text and the necessary option to LaTeX command
+ is kept even when preamble caching is enabled.
+
+ * The new "Glossaries" entry in 'TeX-command-list' runs the command
+ 'makeglossaries'.
+
+ * Fontification of control symbols has been improved. Characters
+ defined in 'font-latex-match-simple-exclude-list' do not receive
+ any fontification. In DocTeX mode, the character '_' is removed
+ from 'font-latex-match-simple-exclude-list' in order to fontify
+ macros like '\__module_foo:nnn' correctly.
+
+ * Fontification of math environments has been improved. Optional
+ and/or mandatory argument(s) to environments are not fontified.
+
+ * 'preview.sty' loads 'luatex85.sty' if possible and should be
+ compatible with newer luaTeX versions.
+
+ * AUCTeX has a new customize option 'TeX-ispell-verb-delimiters'.
+ This string contains usual characters used as delimiters for
+ in-line verbatim macros like '\verb'. Text between delimiters
+ after an in-line verbatim macro will be skipped during spell
+ checking.
+
+ * Fontification of in-line verbatim macros has been improved.
+ 'font-latex.el' recognizes an optional or a mandatory argument for
+ macros like '\Verb' from 'fancyvrb.sty', '\mint' and '\mintinline'
+ from 'minted.sty' and fontifies verbatim content correctly.
+
+ * AUCTeX can put and parse labels in optional argument of
+ environments. Inserting labels is done by new function
+ 'LaTeX-env-label-as-keyval'. A new customize option
+ 'LaTeX-listing-label' is available as prefix to labels in code
+ typesetting environments, e.g. 'lstlisting' environment provided
+ by 'listings' package. 'LaTeX-listing-label' defaults to 'lst:'.
+ Parsing of labels for later referencing relies on two requirements:
+ 1. Label should come as last key-value argument, and
+ 2. label must be enclosed in braces, e.g.
+ \begin{lstlisting}[caption=Some Caption,label={lst:foo}]
+ ...
+ \end{lstlisting}
+
+ * The function 'LaTeX-label' now takes a second optional argument
+ 'NO-INSERT'. When non-'nil', 'LaTeX-label' reads a label and
+ returns it as a string. This argument is also passed to any
+ function bound to 'LaTeX-label-function' (see next item).
+
+ * *Incompatible change:* The signature for the function passed with
+ the customize option 'LaTeX-label-function' has changed. The
+ function bound to this variable is now expected to take an optional
+ second argument 'NO-INSERT'. When this argument is non-'nil', the
+ function should read and only return a label as a string; insertion
+ is done by another function.
+
+ * Directory local variables were ineffective for
+ 'japanese-latex-mode' and 'japanese-plain-tex-mode'. This bug was
+ fixed. (This was actually done in AUCTeX 11.90, but not
+ advertised)
+
+ * The output of Japanese text from Japanese TeX engines is decoded
+ correctly for most cases, according to the encoding of the TeX
+ documents and the locale. The difference between MS Windows, macOS
+ and unix-like OS is taken into account. (This was actually done in
+ AUCTeX 11.90, but not advertised)
+
+ * Quite a few new LaTeX packages are supported.
+
+ * As usual, many bugs were fixed.
+
+News in 11.90
+=============
+
+ * In addition to the completion performed by 'TeX-complete-symbol',
+ AUCTeX now also supports the new Emacs standard completion-at-point
+ facility (see the Emacs command 'completion-at-point'). This also
+ means that modern completion UIs like company-mode work out of the
+ box in TeX and LaTeX buffers.
+
+ * Completion is now aware of being inside a math environment and then
+ completes math macros.
+
+ * AUCTeX is able to display several levels of super- and subscripts,
+ each one raised above and a bit smaller than its basis. For this
+ feature, have a look at the customize options
+ 'font-latex-fontify-script' (especially the new values
+ 'multi-level' and 'invisible') and
+ 'font-latex-fontify-script-max-level'. Also, the script characters
+ '^' and '_' are also fontified with a special face named
+ 'font-latex-script-char-face'.
+
+ * Parsing of format specification in various tabular environments has
+ been improved. The function 'LaTeX-insert-item' ('C-c <LFD>')
+ inserts suitable number of ampersands for '*{num}{cols}'
+ constructs. Style files for LaTeX packages 'tabularx', 'tabulary',
+ 'longtable', 'dcolumn' and 'siunitx' are adapted to take advantage
+ of this improvement.
+
+ * AUCTeX has a new Ispell dictionary 'tex-ispell.el' for macros and
+ environments which will be skipped during spell checking. The
+ activiation of this feature is controlled by a new customize option
+ 'TeX-ispell-extend-skip-list', which is set to 't' and activated by
+ default.
+
+ * AUCTeX has a new customize option 'TeX-raise-frame-function' that
+ is currently only used by Evince and Atril inverse search to raise
+ the Emacs frame.
+
+ * When inserting a new float, AUCTeX will now prompt for a
+ short-caption if the length of the caption provided is greater than
+ a certain size. This size is controlled via a new user option
+ 'LaTeX-short-caption-prompt-length'.
+
+ * Parsing of the compilation log has been reworked. You should
+ encounter fewer mistaken files while navigating through errors and
+ warnings.
+
+ * Two new user options, 'TeX-ignore-warnings' and
+ 'TeX-suppress-ignored-warnings', allow ignoring certain warnings
+ after compilation of the document.
+
+ * A new option, 'TeX-PDF-from-DVI', controls if and how to produce a
+ PDF file by converting a DVI file. This supersedes
+ 'TeX-PDF-via-dvips-ps2pdf' which is still recognized but marked as
+ obsolete and may be removed in future releases.
+
+ * Support for a number of external viewers has been added:
+ * Atril viewer. Forward and inverse search requires version
+ 1.9.1 or later to work.
+
+ * dviout viewer on Windows. Note that this setup works when
+ 'TeX-source-correlate-method' is set to use 'source-specials'
+ for DVI, e.g.:
+ (setq TeX-source-correlate-method
+ '((dvi . source-specials)
+ (pdf . synctex)))
+ which is the default.
+
+ * SumatraPDF viewer on Windows.
+
+ * Zathura viewer. Forward and inverse search requires a recent
+ version of the program to work (3.4 or later).
+
+ * A new function, 'TeX-documentation-texdoc', for reading
+ documentation with 'texdoc' has been added. 'TeX-doc' is still
+ available but now 'C-c ?' runs 'TeX-documentation-texdoc'.
+
+ * AUCTeX has a new custom option
+ 'LaTeX-reftex-cite-format-auto-activate' which controls the
+ automatic activation of citation formats provided by RefTeX when a
+ style file is loaded and RefTeX is enabled. Currently,
+ 'biblatex.el', 'harvard.el', 'jurabib.el' and 'natbib.el' use this
+ feature. If you have customized 'reftex-cite-format' and want to
+ use your settings, you should set this variable to 'nil'.
+
+ * AUCTeX now has limited support for the TikZ package. For the
+ moment, this includes some basic support for prompting the user of
+ arguments to the '\draw' macro.
+
+ * The style 'graphicx.el' went through a bigger overhaul. The
+ optional argument of command '\includegraphics' now supports
+ key-val query; keys can independently be chosen anytime by pressing
+ the <,> key. As a side effect, the variable
+ 'LaTeX-includegraphics-options-alist' is now no-op and is removed
+ from 'tex-style.el'. You can safely remove any customization of it
+ from your init file. The mandatory argument of '\includegraphics'
+ knows about image file extensions supported by the used engine and
+ offers them for inclusion.
+
+ * Support for other LaTeX packages was improved, and style files for
+ several new packages were added.
+
+ * Many bugs were crushed along the way.
+
+News in 11.89
+=============
+
+ * You can now run all commands needed to compile a document and then
+ open the viewer with a single command: 'TeX-command-run-all', bound
+ to 'C-c C-a'.
+
+ * Commands such as LaTeX and View can now be executed conveniently on
+ the current section (or part, chapter, subsection, etc). See
+ 'LaTeX-command-section' and 'LaTeX-command-section-change-level'.
+
+ * Forward and backward search with Evince now also work when only a
+ region of the document is compiled/viewed.
+
+ * To open the PDF output file you can now use also PDF Tools, a
+ document viewer for Emacs. With it, as a plus, forward and
+ backward search is accurate at word level.
+
+ * With new option 'TeX-PDF-via-dvips-ps2pdf' it is possible to
+ compile a document to DVI and then convert it to PDF using
+ 'dvips'-'ps2pdf' before viewing it.
+
+ * New option 'TeX-file-line-error' allows to select file:line:error
+ style for error messages.
+
+ * Indent '\[...\]' math mode as a regular environment by default.
+
+ * Now AUCTeX suggests to run 'makeindex' when appropriate.
+
+ * 'TeX-view-program-list' can contain, as third optional element of
+ each item, the name of the executable(s) needed to open the viewer.
+
+ * 'TeX-expand-list' variable has been split into 'TeX-expand-list'
+ and 'TeX-expand-list-builtin'. Only the former is intended to be
+ customized by the user, the latter contains built-in expanders.
+ You might want to keep in 'TeX-expand-list' only new expansion
+ strings.
+
+ * Before running commands like TeX and LaTeX, now AUCTeX performs
+ some checks. If 'TeX-check-TeX' is non-nil, it will test whether a
+ working TeX distribution is actually present in the system and
+ available to Emacs. Instead, when 'TeX-check-engine' is non-nil,
+ before running LaTeX commands AUCTeX will check whether the correct
+ engine has been set, based upon known restrictions posed by LaTeX
+ packages.
+
+ * Basic support to ConTeXt Mark IV has been added. Users can now
+ select the Mark version to be used with new option
+ 'ConTeXt-Mark-version', and AUCTeX is able to catch error messages
+ in the output log of a Mark IV document.
+
+ * Support for tons of LaTeX packages has been added.
+
+ * Numbers of bugs have been fixed, many minor features have been
+ added.
+
+News in 11.88
+=============
+
+ * 'TeX-PDF-mode' is now enabled by default.
+
+ * Now 'TeX-previous-error' works with TeX commands if the new option
+ 'TeX-parse-all-errors' is non-nil, which is the default. When this
+ option is non-nil, an overview of errors and warnings reported by
+ the TeX compiler can be opened with 'M-x TeX-error-overview <RET>'.
+
+ * Style file authors are encouraged to distinguish common from expert
+ macros and environments, and mark the latter using
+ 'TeX-declare-expert-macros' and
+ 'LaTeX-declare-expert-environments'.
+
+ Users can then restrict completion using
+ 'TeX-complete-expert-commands'.
+
+ * Management of LaTeX package options in the parser was improved.
+ You might need to reparse your documents, especially if you loaded
+ the 'babel' package with language options.
+
+ * Now you can insert '$...$' or '\(...\)' by typing a single '$'. To
+ do this, customize the new option 'TeX-electric-math'.
+ 'TeX-math-close-double-dollar' was removed.
+
+ * 'C-c <RET> documentclass <RET>' completes with all available LaTeX
+ classes, if the 'TeX-arg-input-file-search' variable is non-nil.
+ Completion for class options of the standard LaTeX classes is
+ provided as well.
+
+ * New user options 'LaTeX-default-author',
+ 'LaTeX-fontspec-arg-font-search',
+ 'LaTeX-fontspec-font-list-default', 'TeX-date-format', and
+ 'TeX-insert-braces-alist'. A new possible value
+ ('show-all-optional-args') for 'TeX-insert-macro-default-style' was
+ added. The default value of 'TeX-source-correlate-method' has been
+ changed.
+
+ * 'biblatex' support was greatly expanded. If parsing is enabled,
+ AUCTeX looks at 'backend' option to decide whether to use Biber or
+ BibTeX. The 'LaTeX-biblatex-use-Biber' variable was changed to be
+ file local only and is no more customizable.
+
+ * With some LaTeX classes, the default environment suggested by
+ 'LaTeX-environment' ('C-c C-e') when the current environment is
+ 'document' was changed. With 'beamer' class the default
+ environment is 'frame', with 'letter' it is 'letter', with 'slides'
+ it is 'slide'.
+
+ * Brace pairing feature was enhanced in LaTeX documents. Support for
+ '\bigl', '\Bigl', '\biggl' and '\Biggl', the same as the one for
+ '\left', was added to 'TeX-insert-macro'. For example, 'C-c <RET>
+ bigl <RET> ( <RET>' inserts '\bigl(\bigr)'.
+
+ You can insert brace pair '()', '{}' and '[]' by typing a single
+ left brace if the new user option 'LaTeX-electric-left-right-brace'
+ is enabled.
+
+ Macros '\langle', '\lfloor' and '\lceil', which produce the left
+ part of the paired braces, are treated similarly as '(', '{' and
+ '[' during the course of 'TeX-insert-macro'.
+
+ * Support for dozens of LaTeX packages was added.
+
+ * Tabular-like environments (tabular, tabular*, tabularx, tabulary,
+ array, align, ...) are indented in a nicer and more informative
+ way when the column values of a table line are written across
+ multiple lines in the tex file.
+
+ * The suitable number of ampersands are inserted when you insert
+ array, tabular and tabular* environments with 'C-c C-e'. Similar
+ experience is obtained if you terminate rows in these environments
+ with 'C-c <LFD>'. It supplies line break macro '\\' and inserts
+ the suitable number of ampersands on the next line.
+
+ Similar supports are provided for various amsmath environments.
+
+ * Commands for narrowing to a group ('TeX-narrow-to-group') and to
+ LaTeX environments ('LaTeX-narrow-to-environment') were added.
+
+ * Now arbitrary options can be passed to the TeX processor on a per
+ file basis using the 'TeX-command-extra-options' option.
+
+ * Now 'C-c C-e document <RET>', in an empty document, prompts for
+ '\usepackage' macros in addition to '\documentclass'.
+
+ * 'TeX-add-style-hook' has now a third argument to tell AUCTeX for
+ which dialect (LaTeX, Texinfo or BibTeX) the style hook is
+ registers. Labelling style hook by dialect will avoid applying
+ them not in the right context.
+
+ * There have been lots of bug fixes and feature additions.
+
+News in 11.87
+=============
+
+ * AUCTeX now supports Biber in conjunction with biblatex in addition
+ to BibTeX.
+
+ * Each AUCTeX mode now has its own abbrev table. On Emacsen which
+ provide the possibility to inherit abbrevs from other tables, the
+ abbrevs from the Text mode abbrev table are available as well.
+ Newly defined abbrevs are written to the mode-specific tables,
+ though.
+
+ * The file 'tex-fptex.el' was removed.
+
+ * Forward/backward search for Evince has been improved. If Emacs is
+ compiled with DBUS support and a recent Evince version (3.x) is
+ installed, the communication goes over the desktop bus instead of
+ the command line, resulting in more accurate positioning of point
+ in Emacs and highlighting of the target paragraph in Evince.
+
+ * A problem where Ghostscript threw an /invalidfileaccess error when
+ running preview-latex was fixed.
+
+ * A lot of smaller fixes and additions have been made.
+
+News in 11.86
+=============
+
+ * Parsing of LaTeX output was improved. It is now less likely that
+ AUCTeX opens a non-existent file upon calling 'TeX-next-error'; a
+ problem for example encountered when using MiKTeX 2.8. In addition
+ quoted file names as emitted by MiKTeX are now supported.
+
+ * A new framework for the definition and selection of viewers was
+ implemented. If you have customizations regarding viewers you will
+ have to redo them in this new framework or reenable the old one.
+ See the section on viewers in the manual for details.
+
+ * Comprehensive editing support for PSTricks was added.
+
+ * Support for various LaTeX packages was added, e.g. 'tabularx',
+ 'CJK', and 'hyperref'.
+
+ * An easy way to switch between TeX engines (PDFTeX, LuaTeX, XeTeX,
+ Omega) was added.
+
+ * Support for SyncTeX was added. This involves the command line
+ options for LaTeX and the viewer.
+
+ * Folding can now be customized to use macro arguments as replacement
+ text.
+
+ * 'preview.sty' now works with XeTeX.
+
+ * A lot of smaller and larger bugs have been squashed.
+
+News in 11.85
+=============
+
+ * Font locking has been improved significantly. It is now less prone
+ to color bleeding which could lead to high resource usage. In
+ addition it now includes information about LaTeX macro syntax and
+ can indicate syntactically incorrect macros in LaTeX mode.
+
+ * The license was updated to GPLv3.
+
+ * Support for the nomencl, flashcards and comment LaTeX packages as
+ well as the Icelandic language option of babel were added.
+
+ * Support for folding of math macros was added.
+
+ * Lots of minor bugs in features and documentation fixed.
+
+News in 11.84
+=============
+
+ * There have been problems with the '-without-texmf-dir' option to
+ 'configure' when the value of '-with-kpathsea-sep' was set or
+ determined for an installation system with a default different from
+ that of the runtime system. 'with-kpathsea-sep' has been removed;
+ the setting is now usually determined at runtime.
+
+ Due to this and other problems, preview-latex in the released
+ XEmacs package failed under Windows or with anything except recent
+ 21.5 XEmacsen.
+
+ * AUCTeX and preview-latex have been changed in order to accommodate
+ file names containing spaces. preview-latex now tolerates bad
+ PostScript code polluting the stack (like some Omega fonts).
+
+ * 'preview.sty' had in some cases failed to emit PostScript header
+ specials.
+
+ * Support for folding of comments was added.
+
+ * The 'polish' language option of the babel LaTeX package as well as
+ the polski LaTeX package are now supported. Most notably this
+ means that AUCTeX will help to insert quotation marks as defined by
+ polish.sty ('"`..."'') and polski.sty (',,...''').
+
+ * The TeX tool bar is now available and enabled by default in plain
+ TeX mode.
+
+ * Bug fix in the display of math subscripts and superscripts.
+
+ * Bug fix 'TeX-doc' for Emacs 21.
+
+ * There has been quite a number of other bug fixes to various
+ features and documentation across the board.
+
+News in 11.83
+=============
+
+ * The new function 'TeX-doc' provides easy access to documentation
+ about commands and packages or information related to TeX and
+ friends in general. It is accessible with the key binding 'C-c ?'
+ or the 'Find Documentation...' entry in the mode menus.
+
+ * You can now get rid of generated intermediate and output files by
+ means of the new 'Clean' and 'Clean All' entries in
+ 'TeX-command-list' accessible with 'C-c C-c' or the Command menu.
+
+ * Support for forward search with PDF files was added. That means
+ you can jump to a place in the output file corresponding to the
+ position in the source file. Currently this only works if you use
+ the pdfsync LaTeX package and xpdf as your PDF viewer. The
+ accuracy is in the range of +/-1 page.
+
+ Adding support for this feature required the default value of the
+ variable 'TeX-output-view-style' to be changed. Please make sure
+ you either remove any customizations overriding the new default or
+ incorporate the changes into your customizations if you want to use
+ this feature.
+
+ * TeX error messages of the '-file-line-error' kind are now
+ understood in AUCTeX and preview-latex (parsers are still

+ * The LaTeX tool bar is now enabled by default.
+
+News in 11.82
+=============
+
+ * Support for the MinionPro LaTeX package was added.
+
+ * Warnings and underfull/overfull boxes are now being indicated in
+ the echo area after a LaTeX run, if the respective debugging
+ options are activated with 'TeX-toggle-debug-warnings' ('C-c C-t
+ C-w') or 'TeX-toggle-debug-bad-boxes' ('C-c C-t C-b'). In this
+ case 'TeX-next-error' will find these warnings in addition to
+ normal errors.
+
+ The key binding 'C-c C-w' for 'TeX-toggle-debug-bad-boxes' (which
+ was renamed from 'TeX-toggle-debug-boxes') now is deprecated.
+
+ * AUCTeX now can automatically insert a pair of braces after typing
+ <_> or <^> in math constructs if the new variable
+ 'TeX-electric-sub-and-superscript' is set to a non-nil value.
+
+ * Some language-specific support for French was added. There now is
+ completion support for the commands provided by the 'frenchb' (and
+ 'francais') options of the babel LaTeX package and easier input of
+ French quotation marks ('\\og ...\\fg') which can now be inserted
+ by typing <">.
+
+ * Completion support for options of some LaTeX packages was added.
+
+ * Already in version 11.81 the way to activate AUCTeX changed
+ substantially. This should now be done with '(load "auctex.el" nil
+ t t)' instead of the former '(require 'tex-site)'. Related to this
+ change 'tex-mik.el' does not load 'tex-site.el' anymore. That
+ means if you used only '(require 'tex-mik)' in order to activate
+ AUCTeX, you have to add '(load "auctex.el" nil t t)' before the
+ latter statement. More detailed information can be found in the
+ installation instructions (file INSTALL).
+
+ * Handling of verbatim constructs was consolidated across AUCTeX.
+ This resulted in the font-latex-specific variables
+ 'font-latex-verb-like-commands', 'font-latex-verbatim-macros', and
+ 'font-latex-verbatim-environments' being removed and the more
+ general variables 'LaTeX-verbatim-macros-with-delims',
+ 'LaTeX-verbatim-macros-with-braces', and
+ 'LaTeX-verbatim-environments' being added.
+
+ * The output of a BibTeX run is now checked for warnings and errors,
+ which are reported in the echo area.
+
+ * The aliases for 'font-latex-title-fontify' were removed. Use
+ 'font-latex-fontify-sectioning' instead.
+
+ * The problem that Japanese macros where broken across lines was
+ fixed.
+
+ * Various bug fixes.
+
+News in 11.81
+=============
+
+ * 'LaTeX-mark-section' now marks subsections of a given section as
+ well. The former behavior is available via the prefix argument.
+
+ * preview-latex which was previously available separately became a
+ subsystem of AUCTeX. There is no documented provision for building
+ or installing preview-latex separately. It is still possible to
+ use and install AUCTeX without preview-latex, however.
+
+ * The installation procedures have been overhauled and 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.
+
+ Also note that the way AUCTeX is supposed to be activated changed.
+ Instead of '(require 'tex-site)' you should now use '(load
+ "auctex.el" nil t t)'. While the former method may still work, the
+ new method has the advantage that you can deactivate a preactivated
+ AUCTeX with the statement '(unload-feature 'tex-site)' before any
+ of its modes have been used. This may be important especially for
+ site-wide installations.
+
+ * Support for the babel LaTeX package was added.
+
+ * Folding a buffer now ensures that the whole buffer is fontified
+ before the actual folding is carried out. If this results in
+ unbearably long execution times, you can fall back to the old
+ behavior of relying on stealth font locking to do this job in the
+ background by customizing the variable 'TeX-fold-force-fontify'.
+
+ * Folded content now reveals part of its original text in a tooltip
+ or the echo area when hovering with the mouse pointer over it.
+
+ * The language-specific insertion of quotation marks was generalized.
+ The variables 'LaTeX-german-open-quote',
+ 'LaTeX-german-close-quote', 'LaTeX-german-quote-after-quote',
+ 'LaTeX-italian-open-quote', 'LaTeX-italian-close-quote', and
+ 'LaTeX-italian-quote-after-quote' are now obsolete. If you are not
+ satisfied with the default settings, you should customize
+ 'TeX-quote-language-alist' instead.
+
+ * Similar to language-specific quote insertion, AUCTeX now helps you
+ with hyphens in different languages as well.
+
+ * Fill problems in Japanese text introduced in AUCTeX 11.55 were
+ fixed. AUCTeX tries not to break lines between 1-byte and 2-byte
+ chars. These features will work in Chinese text, too.
+
+ * The scaling factor of the fontification of sectioning commands can
+ now be customized using the variable
+ 'font-latex-fontify-sectioning'. This variable was previously
+ called 'font-latex-title-fontify'; In this release we provide an
+ alias but this will disappear in one of the the next releases. The
+ faces for the sectioning commands are now called
+ 'font-latex-sectioning-N-face' (N=0...5) instead of
+ 'font-latex-title-N-face' (N=1...4). Analogously the names of the
+ variables holding the related keyword lists were changed from
+ 'font-latex-title-N-keywords' to
+ 'font-latex-sectioning-N-keywords'. Make sure to adjust your
+ customizations.
+
+ * Titles in beamer slides marked by the "\frametitle" command are
+ know displayed with the new face 'font-latex-slide-title-face'.
+ You can add macros to be highlighted with this face to
+ 'font-latex-match-slide-title-keywords'.
+
+ * Of course a lot of bugs have been fixed.
+
+News in 11.55
+=============
+
+ * A bug was fixed which lead to the insertion of trailing whitespace
+ during filling. In particular extra spaces were added to sentence
+ endings at the end of lines. You can make this whitespace visible
+ by setting the variable 'show-trailing-whitespace' to 't'. If you
+ want to delete all trailing whitespace in a buffer, type 'M-x
+ delete-trailing-whitespace RET'.
+
+ * A bug was fixed which lead to a '*Compile-Log*' buffer popping up
+ when the first LaTeX file was loaded in an Emacs session.
+
+ * On some systems the presence of an outdated Emacspeak package lead
+ to the error message 'File mode specification error: (error
+ "Variable binding depth exceeds max-specpdl-size")'. Precautions
+ were added which prevent this error from happening. But
+ nevertheless, it is advised to upgrade or uninstall the outdated
+ Emacspeak package.
+
+ * The value of 'TeX-macro-global' is not determined during
+ configuration anymore but at load time of AUCTeX. Consequently the
+ associated configuration option '--with-tex-input-dirs' was
+ removed.
+
+ * Support for the LaTeX Japanese classes 'jsarticle' and 'jsbook' was
+ added.
+
+News in 11.54
+=============
+
+ * The parser (used e.g. for 'TeX-auto-generate-global') was extended
+ to recognize keywords common in LaTeX packages and classes, like
+ "\DeclareRobustCommand" or "\RequirePackage". Additionally a bug
+ was fixed which led to duplicate entries in AUCTeX style files.
+
+ * Folding can now be done for paragraphs and regions besides single
+ constructs and the whole buffer. With the new 'TeX-fold-dwim'
+ command content can both be hidden and shown with a single key
+ binding. In course of these changes new key bindings for unfolding
+ commands where introduced. The old bindings are still present but
+ will be phased out in future releases.
+
+ * Info files of the manual now have a .info extension.
+
+ * There is an experimental tool bar support now. It is not activated
+ by default. If you want to use it, add
+ (add-hook 'LaTeX-mode-hook 'LaTeX-install-toolbar)
+ to your init file.
+
+ * The manual now contains a new chapter "Quick Start". It explains
+ the main features and how to use them, and should be enough for a
+ new user to start using AUCTeX.
+
+ * A new section "Font Locking" was added to the manual which explains
+ syntax highlighting in AUCTeX and its customization. Together with
+ the sections related to folding and outlining, the section is part
+ of the new chapter "Display".
+
+ * Keywords for syntax highlighting of LaTeX constructs to be typeset
+ in bold, italic or typewriter fonts may now be customized. Besides
+ the built-in classes, new keyword classes may be added by
+ customizing the variable 'font-latex-user-keyword-classes'. The
+ customization options can be found in the customization group
+ 'font-latex-keywords'.
+
+ * Verbatim content is now displayed with the 'fixed-pitch' face.
+ (GNU Emacs only)
+
+ * Syntax highlighting should not spill out of verbatim content
+ anymore. (GNU Emacs only)
+
+ * Verbatim commands like '\verb|...|' will not be broken anymore
+ during filling.
+
+ * You can customize the completion for graphic files with
+ 'LaTeX-includegraphics-read-file'.
+
+ * Support for the LaTeX packages 'url', 'listings', 'jurabib' and
+ 'csquotes' was added with regard to command completion and syntax
+ highlighting.
+
+ * Performance of fontification and filling was improved.
+
+ * Insertion of nodes in Texinfo mode now supports completion of
+ existing node names.
+
+ * Setting the variable 'LaTeX-float' to 'nil' now means that you will
+ not be prompted for the float position of figures and tables. You
+ can get the old behaviour of 'nil' by setting the variable to '""',
+ i.e. an empty string.
+
+ * The XEmacs-specific bug concerning 'overlays-at' was fixed.
+
+ * Lots of bug fixes.
+

+
+ * Completion for graphic files in the TeX search path has been added.
+
+ * 'start' is used for the viewer for MiKTeX and fpTeX.

+ deactivate folding in comments.
+
+News in 11.52

+
+ * Bug fixes in the build process.
+
+News in 11.51
+=============
+
+ * PDFTeX and Source Special support did not work with ConTeXt, this
+ has been fixed. Similar for Source Special support under Windows.
+
+ * Omega support has been added.
+
+ * Bug fixes in the build process.
+
+ * 'TeX-fold' now supports folding of environments in Texinfo mode.
+
+News in 11.50
+=============
+
+ * The use of source specials when processing or viewing the document
+ can now be controlled with the new 'TeX-source-specials' minor mode
+ which can be toggled via an entry in the Command menu or the key
+ binding 'C-c C-t C-s'. If you have customized the variable
+ 'TeX-command-list', you have to re-initialize it for this to work.
+ This means to open a customization buffer for the variable by
+ typing 'M-x customize-variable RET TeX-command-list RET', selecting
+ "Erase Customization" and do your customization again with the new
+ default.
+
+ * The content of the command menu now depends on the mode (plain TeX,
+ LaTeX, ConTeXt etc.). Any former customization of the variable
+ 'TeX-command-list' has to be erased. Otherwise the command menu
+ and the customization will not work correctly.
+
+ * Support for hiding and auto-revealing macros, e.g. footnotes or
+ citations, and environments in a buffer was added.
+
+ * You can now control if indentation is done upon typing <RET> by
+ customizing the variable 'TeX-newline-function'.
+
+ * Limited support for 'doc.sty' and 'ltxdoc.cls' ('dtx' files) was
+ added. The new docTeX mode provides functionality for editing
+ documentation parts. This includes formatting (indenting and
+ filling), adding and completion of macros and environments while
+ staying in comments as well as syntax highlighting. (Please note
+ that the mode is not finished yet. For example syntax highlighting
+ does not work yet in XEmacs.)
+
+ * For macro completion in docTeX mode the AUCTeX style files
+ 'doc.el', 'ltxdoc.el' and 'ltx-base.el' were included. The latter
+ provides general support for low-level LaTeX macros and may be used
+ with LaTeX class and style files as well. It is currently not
+ loaded automatically for those files.
+
+ * Support for ConTeXt with a separate ConTeXt mode is now included.
+ Macro definitions for completion are available in Dutch and
+ English.
+
+ * The filling and indentation code was overhauled and is now able to
+ format commented parts of the source syntactically correct. Newly
+ available functionality and customization options are explained in
+ the manual.
+
+ * Filling and indentation in XEmacs with preview-latex and activated
+ previews lead to the insertion of whitespace before multi-line
+ previews. AUCTeX now contains facilities to prevent this problem.
+
+ * If 'TeX-master' is set to 't', AUCTeX will now query for a master
+ file only when a new file is opened. Existing files will be left
+ alone. The new function 'TeX-master-file-ask' (bound to 'C-c _' is
+ provided for adding the variable manually.
+
+ * Sectioning commands are now shown in a larger font on display
+ devices which support such fontification. The variable
+ 'font-latex-title-fontify' can be customized to restore the old
+ appearance, i.e. the usage of a different color instead of a
+ change in size.
+
+ * Support for 'alphanum.sty', 'beamer.cls', 'booktabs.sty',
+ 'captcont.sty', 'emp.sty', 'paralist.sty', 'subfigure.sty' and
+ 'units.sty'/'nicefrac.sty' was added. Credits go to the authors
+ mentioned in the respective AUCTeX style files.
+
+ * Inserting graphics with 'C-c RET \includegraphics RET' was
+ improved. See the variable 'LaTeX-includegraphics-options-alist'.
+
+ * If 'LaTeX-default-position' is 'nil', don't prompt for position
+ arguments in Tabular-like environments.
+
+ * Completion for available packages when using 'C-c RET \usepackage
+ RET' was improved on systems using the kpathsea library.
+
+ * The commenting functionality was fixed. The separate functions for
+ commenting and uncommenting were unified in one function for
+ paragraphs and regions respectively which do both.
+
+ * Syntax highlighting can be customized to fontify quotes delimited
+ by either >>German<< or <<French>> quotation marks by changing the
+ variable 'font-latex-quotes'.
+
+ * Certain TeX/LaTeX keywords for functions, references, variables and
+ warnings will now be fontified specially. You may add your own
+ keywords by customizing the variables
+ 'font-latex-match-function-keywords',
+ 'font-latex-match-reference-keywords',
+ 'font-latex-match-variable-keywords' and
+ 'font-latex-match-warning-keywords'.
+
+ * If you include the style files 'german' or 'ngerman' in a document
+ (directly or via the 'babel' package), you should now customize
+ 'LaTeX-german-open-quote', 'LaTeX-german-close-quote' and
+ 'LaTeX-german-quote-after-quote' instead of 'TeX-open-quote',
+ 'TeX-close-quote' and 'TeX-quote-after-quote' if you want to
+ influence the type of quote insertion.
+
+ * Upon viewing an output file, the right viewer and command line
+ options for it are now determined automatically by looking at the
+ extension of the output file and certain options used in the source
+ file. The behavior can be adapted or extended respectively by
+ customizing the variable 'TeX-output-view-style'.
+
+ * You can control whether 'TeX-insert-macro' ('C-c RET') ask for all
+ optional arguments by customizing the variable
+ 'TeX-insert-macro-default-style'.
+
+ * 'TeX-run-discard' is now able to completely detach a process that
+ it started.
+
+ * The build process was enhanced and is now based on 'autoconf'
+ making installing AUCTeX a mostly automatic process. See the files
+ 'INSTALL' and 'INSTALL.windows' for details.
