+ 3. $recipients is now available in the predata ACL (oversight).
+
+ 4. The value of address_data from a sender verification is now available in
+ $sender_address_data in subsequent conditions in the ACL statement. Note:
+ this is just like $address_data. The value does not persist after the end
+ of the current ACL statement. If you want to preserve it, you can use one
+ of the ACL variables.
+
+ 5. The redirect router has two new options: forbid_sieve_filter and
+ forbid_exim_filter. When filtering is enabled by allow_filter, these
+ options control which type(s) of filtering are permitted. By default, both
+ Exim and Sieve filters are allowed.
+
+ 6. A new option for callouts makes it possible to set a different (usually
+ smaller) timeout for making the SMTP connection. The keyword is "connect".
+ For example:
+
+ verify = sender/callout=5s,connect=1s
+
+ If not specified, it defaults to the general timeout value.
