 New features and fixed bugs in this release
 -------------------------------------------
 
-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.
+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.
