-* Changes in Oort Gnus
-
-** gnus-agent
-
-The Gnus Agent is now enabled by default. This means that, e.g.,
-headers are not downloaded from agentized servers by default (agentize
-servers by using `J a' in the server buffer). Gnus will not start to
-download articles unless you instruct it to do so, though, by using
-e.g. J u or J s from the group buffer. Revert to the old behaviour
-with `(setq gnus-agent nil)'. Note that putting (gnus-agentize) in
-~/.gnus is not needed any more. Now, by default all nntp and nnimap
-servers from gnus-select-method and gnus-secondary-select-method are
-agentized by default (earlier only the server in gnus-select-method
-was agentized). You can view and change which servers should be
-agentized in the Server Buffer.
-
-** gnus-summary-line-format
-
-The default value changed to "%U%R%z%I%(%[%4L: %-23,23f%]%) %s\n".
-Moreover gnus-extra-headers, nnmail-extra-headers and
-gnus-ignored-from-addresses changed their default so that the users
-name will be replaced by the recipient's name or the group name
-posting to for NNTP groups.

-** deuglify.el (gnus-article-outlook-deuglify-article)
+* 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.
