@item Changes in summary and article mode
@itemize @bullet
+
+@item Gnus now supports sticky article buffers. Those are article buffers
+that are not reused when you select another article. @xref{Sticky
+Articles}.
+
@item International host names (@acronym{IDNA}) can now be decoded
inside article bodies using @kbd{W i}
(@code{gnus-summary-idna-message}). This requires that GNU Libidn
(@url{http://www.gnu.org/software/libidn/}) has been installed.
@c FIXME: Also mention @code{message-use-idna}?
+@item The non-@acronym{ASCII} group names handling has been much
+improved. The back ends that fully support non-@acronym{ASCII} group
+names are now @code{nntp}, @code{nnml}, and @code{nnrss}. Also the
+agent, the cache, and the marks features work with those back ends.
+@xref{Non-ASCII Group Names}.
+
@item Gnus now displays @acronym{DNS} master files sent as text/dns
using dns-mode.
See @code{message-fill-column}. @xref{Various Message Variables, ,
Message Headers, message, Message Manual}.
+@item You can now store signature files in a special directory
+named @code{message-signature-directory}.
+
+@item The option @code{message-citation-line-format} controls the format
+of the "Whomever writes:" line. You need to set
+@code{message-citation-line-function} to
+@code{message-insert-formated-citation-line} as well.
