+@cindex Emacs 26, new features in
+
+@itemize
+@cindex threads
+@item
+Emacs now provides a limited form of concurrency with Lisp threads.
+
+@cindex systemd support
+@item
+Emacs now supports @code{systemd}.  The new command-line option
+@option{--fg-daemon} is part of this support, it causes Emacs to run
+in the foreground instead of forking, as under @option{--daemon}.
+
+@item
+Emacs now supports 24-bit true color on text terminals which provide
+that feature.  @xref{Colors on a TTY}.
+
+@cindex double-buffering
+@item
+Emacs on X now supports double-buffering, which eliminates display
+flickering in most situations.
+
+@item
+You can now scroll the Emacs display horizontally using the mouse or
+touchpad.
+
+@cindex line number display
+@item
+Emacs display now includes an optional feature for display of line
+numbers via the @code{display-line-numbers-mode} command.  This
+feature is much faster than the equivalent display offered by packages
+such as @code{linum}, and also provides many optional features like
+relative line numbers.
+
+@cindex horizontal scrolling of current line
+@item
+The automatic horizontal scrolling of the window display when lines
+are truncated can now optionally be enabled only for the current line,
+the line where Emacs shows the cursor.  Under this mode, all the other
+window lines are not scrolled to show characters outside of the
+viewport.
+
+@item
+Letter-case conversions now honor special cases in Turkish and Greek
+scripts.
+
+@cindex Enchant support
+@item
+Support for Enchant is now part of the Emacs spell-checking commands.
+
+@item
+Tramp now supports Google Drive filesystems.
+
+@item
+Emacs can now be built while omitting the details of the machine on
+which it was built, thus making it easier to produce reproducible
+builds.
+
+@item
+Security vulnerability related to Enriched Text mode is removed.
+Enriched mode previously allowed saving @code{display} properties as
+part of text; those properties support evaluating arbitrary Lisp code,
+which opens a vulnerability for Emacs users receiving Enriched Text
+from external sources.  Execution of arbitrary Lisp forms in
+@code{display} properties decoded by Enriched Text mode is now
+disabled by default.

+changes in Emacs 26.
