-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 backend, the PGP passphrase is managed by this mechanism.

+* Changes in Message mode
+
+** Gnus now supports the "hashcash" client puzzle anti-spam mechanism. Use
+`(setq message-generate-hashcash t)' to enable. *Note Hashcash::.
+
+** You can now drag and drop attachments to the Message buffer. See
+`mml-dnd-protocol-alist' and `mml-dnd-attach-options'. *Note MIME:
+(message)MIME.
+
+** The option `message-yank-empty-prefix' now controls how empty lines are
+prefixed in cited text. *Note Insertion Variables: (message)Insertion
+Variables.
+
+** Gnus uses narrowing to hide headers in Message buffers. The
+`References' header is hidden by default. To make all headers visible,
+use `(setq message-hidden-headers nil)'. *Note Message Headers:
+(message)Message Headers.
+
+** You can highlight different levels of citations like in the article
+buffer. See `gnus-message-highlight-citation'.
+
+** `auto-fill-mode' is enabled by default in Message mode. See
+`message-fill-column'. *Note Message Headers: (message)Various Message
+Variables.
+
+** You can now store signature files in a special directory named
+`message-signature-directory'.
+
+** The option `message-citation-line-format' controls the format of the
+"Whomever writes:" line. You need to set
+`message-citation-line-function' to
+`message-insert-formatted-citation-line' as well.
+
+\f
+* Changes in back ends
+
+** The nntp back end stores article marks in `~/News/marks'.
+
+The directory can be changed using the (customizable) variable
+`nntp-marks-directory', and marks can be disabled using the (back end)
+variable `nntp-marks-is-evil'. The advantage of this is that you can
+copy `~/News/marks' (using rsync, scp or whatever) to another Gnus
+installation, and it will realize what articles you have read and
+marked. The data in `~/News/marks' has priority over the same data in
+`~/.newsrc.eld'.
+
+** You can import and export your RSS subscriptions from OPML files. *Note
+RSS::.
