-* Changes in Oort Gnus
-
-** Smileys (":-)", ";-)" etc) are now iconized for Emacs too.
-
-Put (setq gnus-treat-display-smileys nil) in ~/.emacs to disable it.
-
-** Gnus no longer generate the Sender: header automatically.
-
-Earlier it was generated iff the user configurable email address was
-different from the Gnus guessed default user address. As the guessing
-algorithm is rarely correct these days, and (more controversally) the
-only use of the Sender: header was to check if you are entitled to
-cancel/supersede news (which is now solved by Cancel Locks instead,
-see another entry), generation of the header has been disabled by
-default. See the variables `message-required-headers',
-`message-required-news-headers', and `message-required-mail-headers'.
-
-** Features from third party message-utils.el added to message.el.
-
-Message now asks if you wish to remove "(was: <old subject>)" from
-subject lines (see `message-subject-trailing-was-query'). C-c M-m and
-C-c M-f inserts markers indicating included text. C-c C-f a adds a
-X-No-Archive: header. C-c C-f x inserts appropriate headers and a
-note in the body for cross-postings and followups (see the variables
-`message-cross-post-*').
-
-** References and X-Draft-Headers are no longer generated when you
- start composing messages.
-
-** Improved anti-spam features.
-
-Gnus is now able to take out spam from your mail and news streams
-using a wide variety of programs and filter rules. Among the supported
-methods are RBL blocklists, bogofilter and white/blacklists. Hooks
-for easy use of external packages such as SpamAssassin and Hashcash
-are also new.
-
-** Easy inclusion of X-Faces headers.
-
-** In the summary buffer, the new command / N inserts new messages and
-/ o inserts old messages.
-
-** Gnus decodes morse encoded messages if you press W m.
-
-** Unread count correct in nnimap groups.
-
-The estimated number of unread articles in the group buffer should now
-be correct for nnimap groups. This is achieved by calling
-`nnimap-fixup-unread-after-getting-new-news' from the
-`gnus-setup-news-hook' (called on startup) and
-gnus-after-getting-new-news-hook. (called after getting new mail). If
-you have modified those variables from the default, you may want to
-add n-f-u-a-g-n-n again. If you were happy with the estimate and want
-to save some (minimal) time when getting new mail, remove the
-function.
-
-** 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. This means
-variables such as `gnus-message-archive-group' should no longer
-contain quote characters to make groups containing SPC work. Also, if
-you are using 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 since it was inserted directly.
-
-** ~/News/overview/ not used.
-
-As a result of the following change, the ~/News/overview/ directory is
-not used any more. You can safely delete the entire hierarchy.
-
-** gnus-agent
-
-The Gnus Agent has seen a major updated and 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.
