+* 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's 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
+
+** New version of 'nnimap'
+
+'nnimap' has been reimplemented in a mostly-compatible way. See the Gnus
+manual for a description of the new interface. In particular,
+'nnimap-inbox' and the client side split method has changed.
+
+** 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.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
+
+** Symbols like 'gcc-self' now have the same precedence rules in
+'gnus-parameters' as other "real" variables: The last match wins instead
+of the first match.
+
+** 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
+
+** There's now only one variable that determines how HTML is rendered:
+'mm-text-html-renderer'.
+
+** 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::.
+
+** Gnus supports a new sort command in the Summary buffer: 'C-c C-s C-t'
+('gnus-summary-sort-by-recipient'). *Note Summary Sorting::.
+
+** S/MIME now features LDAP user certificate searches. You need to
+configure the server in 'smime-ldap-host-list'.
+
+** URLs inside OpenPGP headers are retrieved and imported to your PGP key
+ring when you click on them.
+
+** Picons can be displayed right from the textual address, see
+'gnus-picon-style'. *Note Picons::.
+
+** ANSI SGR control sequences can be transformed using 'W A'.
+
+ANSI sequences are used in some Chinese hierarchies for highlighting
+articles ('gnus-article-treat-ansi-sequences').
