+* Installation changes
+
+** Upgrading from previous (stable) version if you have used No Gnus.
+
+If you have tried No Gnus (the unstable Gnus branch leading to this
+release) but went back to a stable version, be careful when upgrading to
+this version. In particular, you will probably want to remove the
+`~/News/marks' directory (perhaps selectively), so that flags are read
+from your `~/.newsrc.eld' instead of from the stale marks file, where
+this release will store flags for nntp. See a later entry for more
+information about nntp marks. Note that downgrading isn't safe in
+general.
+
+** Incompatibility when switching from Emacs 23 to Emacs 22 In Emacs 23,
+Gnus uses Emacs' new internal coding system `utf-8-emacs' for saving
+articles drafts and `~/.newsrc.eld'. These files may not be read
+correctly in Emacs 22 and below. If you want to use Gnus across
+different Emacs versions, you may set `mm-auto-save-coding-system' to
+`emacs-mule'.
+
+** Lisp files are now installed in `.../site-lisp/gnus/' by default. It
+defaulted to `.../site-lisp/' formerly. In addition to this, the new
+installer issues a warning if other Gnus installations which will shadow
+the latest one are detected. You can then remove those shadows manually
+or remove them using `make remove-installed-shadows'.
+
+** The installation directory name is allowed to have spaces and/or tabs.
+
+\f
+* New packages and libraries within Gnus
+
+** Gnus includes the Emacs Lisp SASL library.
+
+This provides a clean API to SASL mechanisms from within Emacs. The
+user visible aspects of this, compared to the earlier situation, include
+support for DIGEST-MD5 and NTLM. *Note Emacs SASL: (sasl)Top.
+
+** ManageSieve connections uses the SASL library by default.
+
+The primary change this brings is support for DIGEST-MD5 and NTLM, when
+the server supports it.
+
+** Gnus includes a password cache mechanism in password-cache.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.
+
+** Using EasyPG with Gnus When EasyPG, is available, Gnus will use it
+instead of PGG. EasyPG is an Emacs user interface to GNU Privacy Guard.
+ *Note EasyPG Assistant user's manual: (epa)Top. EasyPG is included in
+Emacs 23 and available separately as well.
+
+\f
+* Changes in group mode
+
+** Old intermediate incoming mail files (`Incoming*') are deleted after a
+couple of days, not immediately. *Note Mail Source Customization::.
+(New in Gnus 5.10.10 / No Gnus 0.8)
+
+
+\f
+* 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::.
+
+** Gnus can selectively display `text/html' articles with a WWW browser
+with `K H'. *Note MIME Commands::.
+
+** 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.
+
+** Gnus supports new limiting commands in the Summary buffer: `/ r'
+(`gnus-summary-limit-to-replied') and `/ R'
+(`gnus-summary-limit-to-recipient'). *Note Limiting::.
+
+** You can now fetch all ticked articles from the server using `Y t'
+(`gnus-summary-insert-ticked-articles'). *Note Summary Generation
+Commands::.
