+11. Tidy the search cache before the fork to do a delivery from a message
+ received from the command line. Otherwise the child will trigger a lookup
+ failure and thereby defer the delivery if it tries to use (for example) a
+ cached ldap connection that the parent has called unbind on.
+
+12. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
+ of $address_data from the recipient verification was clobbered by the
+ sender verification.
+
+13. The value of address_data from a sender verification is now available in
+ $sender_address_data in subsequent conditions in the ACL statement.
+
+14. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
+
+15. Added a new option "connect=<time>" to callout options, to set a different
+ connection timeout.
+
+16. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
+ was its contents. (It was OK if the option was not defined at all.)
+
+17. A "Completed" log line is now written for messages that are removed from
+ the spool by the -Mrm option.
+
+18. New variables $sender_verify_failure and $recipient_verify_failure contain
+ information about exactly what failed.
+
+19. Added -dd to debug only the daemon process.
