-* Changes in Oort Gnus
-
-** Group Carbon Copy (GCC) quoting
-
-To support groups that contains SPC and other weird characters, groups
-are quoted before they are placed in the Gcc: header. While this
-should not cause problems, errorenous local customization may cause
-problems. In particular, if you have local customizations (e.g.,
-variables such as gnus-message-archive-group) that return the string
-"nnml:foo, nnml:bar" (indicating Gcc into two groups) you must change
-it to return the list ("nnml:foo" "nnml:bar"), otherwise the Gcc: line
-will be quoted incorrectly. Note that returning the string "nnml:foo,
-nnml:bar" was incorrect earlier, it just didn't generate any problems.
-
-** gnus-agent
-
-The Gnus Agent is now enabled by default, and 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 by the default, and the agent was disabled by default.
-When the agent is enabled, headers are now also retrieved from the
-Agent cache instead of the backends when possible. Earlier this only
-happened in the unplugged state. You can enroll or remove servers
-with `J a' and `J r' in the server buffer. Gnus will not download
-articles into the Agent cache, unless you instruct it to do so,
-though, by using `J u' or `J s' from the Group buffer. You revert to
-the old behaviour of having the Agent disabled with `(setq gnus-agent
-nil)'. Note that putting (gnus-agentize) in ~/.gnus is not needed any
-more.

+* 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.
