-@heading News since last release
-
-@itemize @bullet
-@item
-@AUCTeX{} now requires GNU Emacs 25.1 or higher.
-
-@item
-@AUCTeX{} tracks the change in Emacs where initial inputs in the
-minibuffer during queries are getting phased out.  Queries for the
-mandatory arguments of macros and environments are adjusted where
-applicable.  The value which will be used after hitting @kbd{RET} without
-other input is shown in the prompt in parentheses prefixed with
-@samp{default}.  For this change the signature of the function
-@code{TeX-arg-length} is altered.  The old argument list was:
-@lisp
-(defun TeX-arg-length (optional &optional prompt
-                                initial-input definition default)
-@end lisp
-
-whereas the new one is:
-@lisp
-(defun TeX-arg-length (optional &optional prompt
-                                default initial-input definition)
-@end lisp
-
-Note the position change of @code{DEFAULT}.
-
-@item
-Indenting of conditionals is improved.  Code inside constructs like
-@samp{\ifx . \else . \fi} is correctly indented.  An interface for style
-files is also introduced which can add their macros to the indentation
-engine.  Check the file @file{algpseudocode.el} for an example.
-
-@item
-You can optionally enable indent inside square brackets @samp{[]} by new
-user options @code{TeX-indent-open-delimiters} and
-@code{TeX-indent-close-delimiters}.
-@ifclear rawfile
-@xref{Indenting}.
-@end ifclear
-
-@item
-Now @file{tex-buf.el} is merged into @file{tex.el} and no longer exists.
-If your personal code has @code{(require 'tex-buf)}, one of the following
-prescriptions would serve.
-@enumerate
-@item
-Remove @code{(require 'tex-buf)}.
-@item
-Replace it with @code{(require 'tex)}.
-@item
-Replace it with @code{(require 'latex)}.
-@end enumerate
-
-@end itemize
-
-@heading News in 13.1
-
-@itemize @bullet
-@item
-In math environments @samp{gather}, @samp{gather*}, @samp{gathered},
-@samp{multline} and @samp{multline*}, fill commands such as @kbd{M-q} and
-@kbd{C-c C-q C-e} are disabled.  This sorts out the inconsistency between
-those and @samp{equation}, @samp{displaymath} environments, in latter of
-which filling is already disabled.
-
-If you want filling in such environments, customize
-@code{LaTeX-indent-environment-list} to remove them.
-
-Auto fill continues to work in such environment anyway.
-
-In addition, @AUCTeX{} adds support of alignment at @samp{&} sign in
-@samp{align}-like environments such as @samp{alignat}, @samp{aligned} and
-so on, as well as @samp{matrix}-like environments such as @samp{pmatrix},
-@samp{bmatrix} and so on.
-
-@item
-Now two commands @samp{Texindex} and @samp{Texi2dvi} are available when
-you type @kbd{C-c C-c} in Texinfo mode.  The command @samp{Texindex} runs
-@command{texindex} on index files and @samp{Texi2dvi} runs
-@command{pdftexi2dvi} or @command{texi2dvi} according to the value of
-@code{TeX-PDF-mode}.
-
-So you can typeset Texinfo documents into @acronym{PDF} or @acronym{DVI}
-format from within @AUCTeX{}.
-
-@item
-@AUCTeX{}'s own help messages for @LaTeX{} errors are now shown only for
-@LaTeX{} runs.  @AUCTeX{} shows raw error/warning messages found in
-@file{.log} files for runs of formats other than @LaTeX{}, such as plain
-@TeX{}, @ConTeXt{} and Texinfo, as it does even for @LaTeX{} runs when it
-can't find a matching entry in its own help message catalogue.
-
-Due to this change, customize option @code{TeX-error-description-list} can
-no longer have a fallback entry that matches any error.  If your
-customized value includes such entry, typically @samp{(".*" . "No help
-available")}, please remove it.
-
-@item
-Two functions @code{TeX-split-string} and @code{TeX-assoc} are now
-obsolete and will be removed in future release.  If your personal code
-uses these functions, use @code{split-string} and @code{assoc-string}
-instead.
-
-@item
-The function @code{TeX-read-key-val} now accepts a function call as second
-argument.  This change should help @AUCTeX{} style writers who use
-@code{TeX-arg-key-val} and have to deal with dynamic key-values.  Example
-of usage:
-@lisp
-(TeX-add-style-hook "foo"
- (lambda ()
-   (TeX-add-symbols
-    '("bar" (TeX-arg-key-val (function-returning-key-val))))))
-@end lisp
-
-@item
-Since @AUCTeX{} 12.2, @kbd{C-x C-w} accidentally disabled the parse on
-save in that buffer, even when you enabled @code{TeX-auto-save} option.
-This bug was fixed.
-
-@item
-@AUCTeX{} now requires GNU Emacs 24.3 or higher.
-
-@item
-Old implementations for viewers were discarded, as announced long before.
-The variables @code{TeX-output-view-style} and @code{TeX-view-style} have
-no effect now.  The former placeholders @samp{%v} and @samp{%vv} in
-@code{TeX-command-list} are ignored.
-
-@item
-@AUCTeX{} now uses lexical binding which has been introduced in Emacs
-24.  This change should have no user-visible effect and require no
-manual adaptions except in the following cases.
-
-@itemize @minus
-@item
-Entries added to the customization variable @code{TeX-expand-list} also
-had access to variables @code{command} and @code{pos}.  Those are now
-properly declared and named @code{TeX-expand-command} and
-@code{TeX-expand-pos}.
-
-@item
-Entries added to the customization variable @code{TeX-expand-list} had
-access to a variable @code{file} which was bound to
-@code{TeX-active-master}, i.e., it evaluated to either the master or
-region file.  This usage must be replaced with either
-@code{TeX-active-master} or @code{TeX-active-master-with-quotes}.
-
-@item
-Viewer entries in @code{TeX-view-program-list} also had access to a
-variable @code{file} which was bound to the name of the master or region
-file without extension.  Instead, the function @code{TeX-active-master}
-has to be used now.
-
-@item
-Macro argument parsing functions could set a variable @code{exit-mark}
-to the buffer position where point should be left after all arguments
-have been read.  This variable is now named @code{TeX-exit-mark}.
-
-@item
-The functions in @code{LaTeX-section-hook} had access or modified the
-previously undeclared variables @code{title}, @code{name}, @code{level},
-@code{done-mark}, and @code{toc}.  These variables are now properly
-declared and have the @samp{LaTeX-} prefix, e.g.,
-@code{LaTeX-done-mark}.
-
-@item
-The functions in @code{ConTeXt-numbered-section-hook} and
-@code{ConTeXt-unnumbered-section-hook} had access or modified the
-previously undeclared variables @code{title}, @code{name}, @code{level},
-@code{done-mark}, and @code{reference}.  These variables are now
-properly declared and have the @samp{ConTeXt-} prefix, e.g.,
-@code{ConTeXt-title}.
-
-@item
-The functions in @code{TeX-translate-location-hook} could access and
-modify the free variables @code{file}, @code{line}, @code{error},
-@code{offset}, @code{context}, and @code{string}.  Those are now properly
-declared variables with the prefix @samp{TeX-translate-location-}, e.g.,
-@code{TeX-translate-location-file}.
-@end itemize
-
-@item
-The constant @code{LaTeX-dialect} has been renamed to @code{TeX-dialect}
-and moved from @file{latex.el} to @file{tex.el}.  @code{LaTeX-dialect}
-now is an obsolete alias.
-
-@item
-The style @file{latexinfo.el} is removed from @AUCTeX{}.
-@file{latexinfo.el} was meant to support latexinfo which in return was a
-@LaTeX{}-2.09 extension of Texinfo, but didn't manage to replace Texinfo.
-
-@item
-The style @file{siunitx.el} is updated to support package version 3.
-Key-value options provided by older package versions are removed,
-deprecated macros and units are not supported anymore.
-
-@item
-@AUCTeX{} has preliminary support for @LaTeX{}-hooks.  Hooks provided by
-@LaTeX{} kernel are known and available for completion in
-@samp{\AddToHook}, @samp{\RemoveFromHook} and @samp{\AddToHookNext}.
-
-@item
-@AUCTeX{} is now able to place all generated output files, including those
-that are produced by applications running under @AUCTeX{}, temporary files
-related to region processing and @previewlatex{} files, in an output
-directory.  To use this feature, set the new user option
-@code{TeX-output-dir} to the absolute path of the output directory or a
-relative path which would be interpreted as being relative to the master
-file in a multifile document.
-
-Note that this feature doesn't work if the document includes sub file
-placed in sub directory below the main file via @samp{\include} command.
-
-@item
-Many other bugs were fixed.
-@end itemize
-
-@heading News in 12.3
-
-@itemize @bullet
-@item
-Support for @samp{PSTricks} is now @acronym{PDF}-oriented.  @AUCTeX{} no
-longer turns off PDF mode for @samp{PSTricks} documents even without
-@samp{pst-pdf}.  It now sets up @code{TeX-PDF-from-DVI} option so that
-@acronym{PDF} output is generated when @code{TeX-PDF-mode} is enabled
-(default).  Users who want @acronym{DVI} output should disable PDF mode
-explicitly by file local variable, or customize @code{TeX-PDF-mode} to
-@code{nil}.
-
-@item
-The function @code{font-latex-update-font-lock} has been obsoleted in
-order to fix @samp{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 @code{font-lock-flush} in the
-former case and @code{font-latex-set-syntactic-keywords} in the latter
-case.  The function @code{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.
-
-@item
-Math expression highlighting was improved.  Highlighting for documents
-with a lot of inline math expressions @samp{$...$} won't get scrambled
-now (@samp{bug#33139}).
-
-In addition, it is no longer recommended to customize
-@code{font-latex-math-environments}.  Use @code{texmathp-tex-commands}
-instead.
-@ifclear rawfile
-@xref{Fontification of math}.
-@end ifclear
-
-@item
-@AUCTeX{} tracks changes in @LaTeX{}2e 2020-02-02 release.  @AUCTeX{}
-supports the improvements to @LaTeX{} font selection mechanism (NFSS).
-New macros like @samp{\textsw} or @samp{\textulc} are added to font
-insertion keyboard commands.
-@ifset rawfile
-See the section for inserting font specifiers for details.
-@end ifset
-@ifclear rawfile
-@xref{Font Specifiers}, for details.
-@end ifclear
-Further, the entries in the menu @samp{LaTeX}, @samp{Insert Font} are reorganized and
-adjusted accordingly.
-
-Macros previously provided by @file{textcomp.sty} are now part of
-@LaTeX{} kernel.  @AUCTeX{} tracks this change as well and support for
-the new macro @samp{\legacyoldstylenums} is added.
-
-@item
-Insertion of environments in @LaTeX{} documents (i.e.@: @kbd{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.
-
-@item
-More bugs fixed, other minor features implemented.
-@end itemize
-
-@heading News in 12.2
-
-@itemize @bullet
-@item
-@AUCTeX{} reflects the changes in @LaTeX{}2e 2019-10-01 release.
-@samp{filecontents} environment now takes an optional argument and can
-be used anywhere in a document.  The macros @samp{\Ref} and
-@samp{\labelformat} are moved from @file{varioref.sty} to @LaTeX{}
-kernel.  @samp{amsmath} has a new macro @samp{\overunderset}.
-
-@item
-A new method is implemented in @previewlatex{} to adjust the foreground
-colors of generated images to those of Emacs, when the @LaTeX{} command
-produces @acronym{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 @previewlatex{}, the users are encouraged to set up the new
-user option @code{preview-pdf-color-adjust-method} to choose appropriate
-option among the three: new, traditional and fallback method.
-
-@item
-@AUCTeX{} has support for the Flymake package in Emacs 26 or newer.  To
-enable, call @kbd{M-x flymake-mode @key{RET}} or add this to your
-@file{.emacs} file:
-@lisp
-(add-hook 'LaTeX-mode-hook #'flymake-mode)
-@end lisp
-
-@item
-The way the option @code{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.
-
-@item
-A former customize option @code{japanese-TeX-command-list} is removed.
-Use @code{japanese-TeX-engine-default}, or if it's really necessary,
-customize @code{TeX-command-list} directly if the task which the option
-used to carry is required.
-
-@item
-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 @command{latex} command.  It also fails for region compilation (@kbd{C-c
-C-r} and so on) with documents of non-ascii file name.  In addition, it
-no longer works with @previewlatex{}.  We consider this incompatibility
-is permissible because e-@TeX{} extension is enabled for standard
-@LaTeX{} by default long ago.  @LaTeX{} variants such as Xe@LaTeX{} and
-Lua@LaTeX{} are not affected.
-
-@item
-Key binds in Texinfo mode are improved.  Typing @kbd{$}, @kbd{^},
-@kbd{_} and @kbd{\} now just self-inserts without pointless side effects
-in Texinfo mode.
-
-In addition, the option @code{TeX-electric-escape} is now effective in
-Texinfo mode.  When it is enabled, typing @kbd{@@} will invoke
-@code{TeX-electric-macro} offering completion in similar style with
-other @TeX{} modes of @AUCTeX{}.
-
-@item
-Fontification support for @samp{biblatex} package is improved and
-updated to macros provided by package version 3.12.  For qualified
-lists, at least 2 mandatory arguments are fontified.
-
-@item
-Support for column specifiers @samp{w} and @samp{W} provided by
-@samp{array} package is added to @file{array.el}.  The correct counting
-of columns only works when the @samp{align} parameter is enclosed in
-braces, e.g., @samp{w@{l@}@{3cm@}}.  The short version @samp{wl@{3cm@}}
-is not supported.
-
-@item
-Entries for @samp{PDF Tools} are added in
-@code{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:
-@lisp
-(setq TeX-view-program-selection '((output-pdf "PDF Tools")))
-@end lisp
-
-@item
-Several other bugs were fixed, many minor features were added.
-@end itemize
-
-@heading News in 12.1
-
-@itemize @bullet
-@item
-@AUCTeX{} now requires GNU Emacs 24 or higher.  Support for XEmacs has
-been dropped.
-
-@item
-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.
-@end itemize
-
-@heading News in 11.92
-
-@itemize @bullet
-@item
-@previewlatex{} is compatible with Ghostscript 9.22 where the operator
-@samp{.runandhide} is removed.  All occurrences of @samp{.runandhide} in
-@previewlatex{} are replaced by alternative code making it work with
-Ghostscript 9.22 again.
-
-@item
-@AUCTeX{} has a new customize option
-@code{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
-@code{defcustom} until this release.
-
-@item
-The window system focus is pulled back to Emacs when viewing with
-evince-compatible viewers if a new customize option
-@code{TeX-view-evince-keep-focus} is non-nil.
-
-@item
-The usual dose of bug fixes was administered.
-@end itemize
-
-@heading News in 11.91
-
-@itemize @bullet
-@item
-Now @AUCTeX{} has a logo.  The @LaTeX{} code to create it is available
-in the @file{etc/} directory of the package.
-
-@item
-Add support for @command{upmendex}, an extension of @command{makeindex}
-capable of sorting indexes by unicode based ICU.
-
-@item
-Fix @previewlatex{} 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.
-
-@item
-The new ``Glossaries'' entry in @code{TeX-command-list} runs the command
-@command{makeglossaries}.
-
-@item
-Fontification of control symbols has been improved.  Characters defined
-in @code{font-latex-match-simple-exclude-list} do not receive any
-fontification.  In Doc@TeX{} mode, the character @samp{_} is removed
-from @code{font-latex-match-simple-exclude-list} in order to fontify
-macros like @samp{\__module_foo:nnn} correctly.
-
-@item
-Fontification of math environments has been improved.  Optional and/or
-mandatory argument(s) to environments are not fontified.
-
-@item
-@file{preview.sty} loads @file{luatex85.sty} if possible and should be
-compatible with newer lua@TeX{} versions.
-
-@item
-@AUCTeX{} has a new customize option @code{TeX-ispell-verb-delimiters}.
-This string contains usual characters used as delimiters for in-line
-verbatim macros like @samp{\verb}.  Text between delimiters after an
-in-line verbatim macro will be skipped during spell checking.
-
-@item
-Fontification of in-line verbatim macros has been improved.
-@file{font-latex.el} recognizes an optional or a mandatory argument for
-macros like @samp{\Verb} from @file{fancyvrb.sty}, @samp{\mint} and
-@samp{\mintinline} from @file{minted.sty} and fontifies verbatim content
-correctly.
-
-@item
-@AUCTeX{} can put and parse labels in optional argument of environments.
-Inserting labels is done by new function
-@code{LaTeX-env-label-as-keyval}.  A new customize option
-@code{LaTeX-listing-label} is available as prefix to labels in code
-typesetting environments, e.g.@: @samp{lstlisting} environment provided by
-@samp{listings} package.  @code{LaTeX-listing-label} defaults to
-@code{lst:}.  Parsing of labels for later referencing relies on two
-requirements:
-@enumerate
-@item
-Label should come as last key-value argument, and
-@item
-label must be enclosed in braces, e.g.
-@example
-\begin@{lstlisting@}[caption=Some Caption,label=@{lst:foo@}]
-...
-\end@{lstlisting@}
-@end example
-@end enumerate
-
-@item
-The function @code{LaTeX-label} now takes a second optional argument
-@code{NO-INSERT}.  When non-@code{nil}, @code{LaTeX-label} reads a label
-and returns it as a string.  This argument is also passed to any
-function bound to @code{LaTeX-label-function} (see next item).
-
-@item
-@strong{Incompatible change:} The signature for the function passed with
-the customize option @code{LaTeX-label-function} has changed.  The
-function bound to this variable is now expected to take an optional
-second argument @code{NO-INSERT}.  When this argument is non-@code{nil},
-the function should read and only return a label as a string; insertion
-is done by another function.
-
-@item
-Directory local variables were ineffective for
-@code{japanese-latex-mode} and @code{japanese-plain-tex-mode}.  This bug
-was fixed.  (This was actually done in @AUCTeX{} 11.90, but not
-advertised)
-
-@item
-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)
-
-@item
-Quite a few new @LaTeX{} packages are supported.
-
-@item
-As usual, many bugs were fixed.
-
-@end itemize
-
-@heading News in 11.90
-
-@itemize @bullet
-@item
-In addition to the completion performed by @code{TeX-complete-symbol},
-@AUCTeX{} now also supports the new Emacs standard completion-at-point
-facility (see the Emacs command @code{completion-at-point}).  This also
-means that modern completion UIs like @i{company-mode} work out of the
-box in @TeX{} and @LaTeX{} buffers.
-@ifclear rawfile
-@xref{Completion}, for details.
-@end ifclear
-
-@item
-Completion is now aware of being inside a math environment and then
-completes math macros.
-
-@item
-@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
-@code{font-latex-fontify-script} (especially the new values
-@code{multi-level} and @code{invisible}) and
-@code{font-latex-fontify-script-max-level}.  Also, the script characters
-@samp{^} and @samp{_} are also fontified with a special face named
-@code{font-latex-script-char-face}.
-@ifclear rawfile
-@xref{Fontification of math}, for details.
-@end ifclear
-
-@item
-Parsing of format specification in various tabular environments has been
-improved.  The function @code{LaTeX-insert-item} (@kbd{C-c @key{LFD}})
-inserts suitable number of ampersands for @samp{*@{num@}@{cols@}}
-constructs.  Style files for @LaTeX{} packages @samp{tabularx},
-@samp{tabulary}, @samp{longtable}, @samp{dcolumn} and @samp{siunitx} are
-adapted to take advantage of this improvement.
-
-@item
-@AUCTeX{} has a new Ispell dictionary @file{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
-@code{TeX-ispell-extend-skip-list}, which is set to @code{t} and
-activated by default.
-
-@item
-@AUCTeX{} has a new customize option @code{TeX-raise-frame-function}
-that is currently only used by Evince and Atril inverse search to raise
-the Emacs frame.
-
-@item
-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
-@code{LaTeX-short-caption-prompt-length}.
-
-@item
-Parsing of the compilation log has been reworked.  You should encounter
-fewer mistaken files while navigating through errors and warnings.
-
-@item
-Two new user options, @code{TeX-ignore-warnings} and
-@code{TeX-suppress-ignored-warnings}, allow ignoring certain warnings
-after compilation of the document.
-@ifclear rawfile
-@xref{Ignoring warnings}, for details.
-@end ifclear
-
-@item
-A new option, @code{TeX-PDF-from-DVI}, controls if and how to produce a
-@acronym{PDF} file by converting a @acronym{DVI} file.  This supersedes
-@code{TeX-PDF-via-dvips-ps2pdf} which is still recognized but marked as
-obsolete and may be removed in future releases.
-
-@item
-Support for a number of external viewers has been added:
-@itemize
-@item
-Atril viewer.  Forward and inverse search requires version 1.9.1 or
-later to work.
-
-@item
-dviout viewer on Windows.  Note that this setup works when
-@code{TeX-source-correlate-method} is set to use @samp{source-specials}
-for @acronym{DVI}, e.g.:
-@lisp
-(setq TeX-source-correlate-method
-      '((dvi . source-specials)
-        (pdf . synctex)))
-@end lisp
-which is the default.
-
-@item
-SumatraPDF viewer on Windows.
-
-@item
-Zathura viewer.  Forward and inverse search requires a recent version of
-the program to work (3.4 or later).
-@end itemize
-

-The use of source specials when processing or viewing the document can
-now be controlled with the new @code{TeX-source-specials} minor mode
-which can be toggled via an entry in the Command menu or the key binding
-@kbd{C-c C-t C-s}.  If you have customized the variable
-@code{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
-@kbd{M-x customize-variable @key{RET} TeX-command-list @key{RET}}, selecting
-``Erase Customization'' and do your customization again with the new
-default.
-
-@item
-The content of the command menu now depends on the mode (plain @TeX{},
-@LaTeX{}, @ConTeXt{} etc.).  Any former customization of the variable
-@code{TeX-command-list} has to be erased.  Otherwise the command menu
-and the customization will not work correctly.

-Limited support for @code{doc.sty} and @code{ltxdoc.cls} (@samp{dtx}
-files) was added.  The new doc@TeX{} 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.)
-
-@item
-For macro completion in doc@TeX{} mode the @AUCTeX{} style files
-@file{doc.el}, @file{ltxdoc.el} and @file{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.
-
-@item
-Support for @ConTeXt{} with a separate @ConTeXt{} mode is now included.
-Macro definitions for completion are available in Dutch and English.
-
-@item
-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.
-
-@item
-Filling and indentation in XEmacs with @previewlatex{} and activated
-previews lead to the insertion of whitespace before multi-line previews.
-@AUCTeX{} now contains facilities to prevent this problem.
-
-@item
-If @code{TeX-master} is set to @code{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 @code{TeX-master-file-ask} (bound to @kbd{C-c
-_} is provided for adding the variable manually.
-
-@item
-Sectioning commands are now shown in a larger font on display devices
-which support such fontification.  The variable
-@code{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.
-
-@item
-Support for @code{alphanum.sty}, @code{beamer.cls}, @code{booktabs.sty},
-@code{captcont.sty}, @code{emp.sty}, @code{paralist.sty},
-@code{subfigure.sty} and @code{units.sty}/@code{nicefrac.sty} was added.
-Credits go to the authors mentioned in the respective @AUCTeX{} style
-files.
-
-@item
-Inserting graphics with @kbd{C-c @key{RET} includegraphics @key{RET}} was improved.
-See the variable @code{LaTeX-includegraphics-options-alist}.

-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.
-
-@item
-Syntax highlighting can be customized to fontify quotes delimited by
-either >>German<< or <<French>> quotation marks by changing the variable
-@code{font-latex-quotes}.
-
-@item
-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
-@code{font-latex-match-function-keywords},
-@code{font-latex-match-reference-keywords},
-@code{font-latex-match-variable-keywords} and
-@code{font-latex-match-warning-keywords}.
-
-@item
-If you include the style files @file{german} or @file{ngerman} in a
-document (directly or via the @samp{babel} package), you should now
-customize @code{LaTeX-german-open-quote},
-@code{LaTeX-german-close-quote} and
-@code{LaTeX-german-quote-after-quote} instead of @code{TeX-open-quote},
-@code{TeX-close-quote} and @code{TeX-quote-after-quote} if you want to
-influence the type of quote insertion.
-
-@item
-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 @code{TeX-output-view-style}.
-
-@item
-You can control whether @code{TeX-insert-macro} (@kbd{C-c @key{RET}}) ask for
