+@item Changes in Message mode
+
+@itemize @bullet
+@item Gnus now supports the ``hashcash'' client puzzle anti-spam mechanism.
+Use @code{(setq message-generate-hashcash t)} to enable.
+@xref{Hashcash}.
+
+@item You can now drag and drop attachments to the Message buffer.
+See @code{mml-dnd-protocol-alist} and @code{mml-dnd-attach-options}.
+@xref{MIME, ,MIME, message, Message Manual}.
+
+@item The option @code{message-yank-empty-prefix} now controls how
+empty lines are prefixed in cited text. @xref{Insertion Variables,
+,Insertion Variables, message, Message Manual}.
+
+@item Gnus uses narrowing to hide headers in Message buffers.
+The @code{References} header is hidden by default. To make all
+headers visible, use @code{(setq message-hidden-headers nil)}.

+
+@item Changes in back ends
+
+@itemize @bullet
+@item The nntp back end stores article marks in @file{~/News/marks}.
+
+The directory can be changed using the (customizable) variable
+@code{nntp-marks-directory}, and marks can be disabled using the
+(back end) variable @code{nntp-marks-is-evil}. The advantage of this
+is that you can copy @file{~/News/marks} (using rsync, scp or
+whatever) to another Gnus installation, and it will realize what
+articles you have read and marked. The data in @file{~/News/marks}
+has priority over the same data in @file{~/.newsrc.eld}.
+
+@item
+You can import and export your @acronym{RSS} subscriptions from
+@acronym{OPML} files. @xref{RSS}.
+
+@item @acronym{IMAP} identity (@acronym{RFC} 2971) is supported.
+
+By default, Gnus does not send any information about itself, but you can
+customize it using the variable @code{nnimap-id}.
+
+@item The @code{nnrss} back end now supports multilingual text.
+Non-@acronym{ASCII} group names for the @code{nnrss} groups are also
+supported. @xref{RSS}.
