+6. All authenticators now have a server_condition option. Previously, only
+ plaintext had this, and this has not changed: it must be set to the
+ authenticator as a server. For the others, if server_condition is set, it is
+ expanded if authentication is successful, and treated exactly as it is in
+ plaintext. This can serve as a means of adding authorization to an
+ authenticator.
+
+7. There is a new command-line option called -Mset. It is useful only in
+ conjunction with -be (that is, when testing string expansions). It must be
+ followed by a message id; Exim loads the given message before doing the
+ expansions, thus setting message-specific variables such as $message_size
+ and the header variables. This feature is provided to make it easier to test
+ expansions that make use of these variables. However, Exim must be called by
+ an admin user when -Mset is used.
