+** International host names (IDNA) can now be decoded inside article
+bodies using `W i' (`gnus-summary-idna-message'). This require that
+GNU Libidn (<http://www.gnu.org/software/libidn/>) has been installed.
+
+** Gnus includes an Emacs Lisp SASL library.
+
+This provide 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.
+
+** ManageSieve connections uses the SASL library by default.
+
+The primary change this brings is support for DIGEST-MD5 and NTLM,
+when the server support it.
+
+** Gnus include 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 quering the user about whether to do so.
