+ 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
+ was an oversight, and furthermore, ever since the addition of extra
+ controls (e.g. 4.43/32), the checks on when to allow different forms of
+ "control" were broken. There should now be diagnostics for all cases when a
+ control that does not make sense is encountered.
+
+ 9. Added the /retain_sender option to "control=submission".
+
+10. $recipients is now available in the predata ACL (oversight).
+
+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.
+
+20. Incorporated Michael Haardt's patch to ldap.c for improving the way it
+ handles timeouts, both on the server side and network timeouts. Renamed the
+ CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
+
+21. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
+ It is now set to "smtps".
+
+22. $host_address is now set to the target address during the checking of
+ ignore_target_hosts.
+
+23. When checking ignore_target_hosts for an ipliteral router, no host name was
+ being passed; this would have caused $sender_host_name to have been used if
+ matching the list had actually called for a host name (not very likely,
+ since this list is usually IP addresses). A host name is now passed as
+ "[x.x.x.x]".
