+ 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]".
+
+24. Changed the calls that set up the SIGCHLD handler in the daemon to use the
+ code that specifies a non-restarting handler (typically sigaction() in
+ modern systems) in an attempt to fix a rare and obscure crash bug.
+
+25. Narrowed the window for a race in the daemon that could cause it to ignore
+ SIGCHLD signals. This is not a major problem, because they are used only to
+ wake it up if nothing else does.
+
+26. A malformed maildirsize file could cause Exim to calculate negative values
+ for the mailbox size or file count. Odd effects could occur as a result.
+ The maildirsize information is now recalculated if the size or filecount
+ end up negative.
+
+27. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
+ support for a long time. Removed HAVE_SYS_VFS_H.
+
+28. Installed the latest version of exipick from John Jetmore.
+
+29. In an address list, if the pattern was not a regular expression, an empty
+ subject address (from a bounce message) matched only if the pattern was an
+ empty string. Non-empty patterns were not even tested. This was the wrong
+ because it is perfectly reasonable to use an empty address as part of a
+ database query. An empty address is now tested by patterns that are
+ lookups. However, all the other forms of pattern expect the subject to
+ contain a local part and a domain, and therefore, for them, an empty
+ address still always fails if the pattern is not itself empty.
+
+30. Exim went into a mad DNS loop when attempting to do a callout where the
+ host was specified on an smtp transport, and looking it up yielded more
+ than one IP address.
+
+31. Re-factored the code for checking spool and log partition space into a
+ function that finds that data and another that does the check. The former
+ is then used to implement four new variables: $spool_space, $log_space,
+ $spool_inodes, and $log_inodes.
+
+32. The RFC2047 encoding function was originally intended for short strings
+ such as real names; it was not keeping to the 75-character limit for
+ encoded words that the RFC imposes. It now respects the limit, and
+ generates multiple encoded words if necessary. To be on the safe side, I
+ have increased the buffer size for the ${rfc2047: expansion operator from
+ 1024 to 2048 bytes.
+
+33. It is now permitted to omit both strings after an "if" condition; if the
+ condition is true, the result is "true". As before, when the second string
+ is omitted, a false condition yields an empty string. This makes it less
+ cumbersome to write custom ACL and router conditions.
+
+34. Failure to deliver a bounce message always caused it to be frozen, even if
+ there was an errors_to setting on the router. The errors_to setting is now
+ respected.
+
+35. If an IPv6 address is given for -bh or -bhc, it is now converted to the
+ canonical form (fully expanded) before being placed in
+ $sender_host_address.
