+** Gnus includes a password cache mechanism in password.el.
+
+It is enabled by default (see `password-cache'), with a short timeout of
+16 seconds (see `password-cache-expiry'). If PGG is used as the PGP
+back end, the PGP passphrase is managed by this mechanism. Passwords
+for ManageSieve connections are managed by this mechanism, after
+querying the user about whether to do so.

+* Changes in summary and article mode
+
+** Gnus now supports sticky article buffers. Those are article buffers
+that are not reused when you select another article. *Note Sticky
+Articles::.
+
+** International host names (IDNA) can now be decoded inside article bodies
+using `W i' (`gnus-summary-idna-message'). This requires that GNU Libidn
+(`http://www.gnu.org/software/libidn/') has been installed.
+
+** The non-ASCII group names handling has been much improved. The back
+ends that fully support non-ASCII group names are now `nntp', `nnml',
+and `nnrss'. Also the agent, the cache, and the marks features work
+with those back ends. *Note Non-ASCII Group Names::.
+
+** Gnus now displays DNS master files sent as text/dns using dns-mode.
