       less than full, an overflow happened when the terminating "\n" was
       subsequently added.
 

+PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry
+      when the result of a list match is failure because a DNS lookup failed.
+
+PH/40 RM_COMMAND is now used in the building process.
+
+PH/41 Added a "distclean" target to the top-level Makefile; it deletes all
+      the "build-* directories that it finds.
+
+PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP
+      address in a domain literal was a prefix of an interface address.
+
+PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains
+      when verifying a sender address, unless rewrite_headers is false.
+
+PH/44 Wrote a long comment about why errors_to addresses are verified as
+      recipients, not senders.
+
+TF/01 Add missing LIBS=-lm to OS/Makefile-OpenBSD which was overlooked when
+      the ratelimit ACL was added.
+
+PH/45 Added $smtp_command for the full command (cf $smtp_command_argument).
+
+PH/46 Added extra information about PostgreSQL errors to the error string.
+
+PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
+      avoiding the need to install special zones in a real server. This is
+      backwards compatible; if it can't find the fake resolver, it drops back.
+      Thus, both old and new test suites can be run.
+
+TF/02 Added util/ratelimit.pl
+
+TF/03 Minor fix to the ratelimit code to improve its behaviour in case the
+      clock is set back in time.
+
+TF/04 Fix the ratelimit support in exim_fixdb. Patch provided by Brian
+      Candler <B.Candler@pobox.com>.
+
+TF/05 The fix for PH/43 was not completely correct; widen_domains is always
+      OK for addresses that are the result of redirections.
+
+PH/48 A number of further additions for the benefit of the new test suite,
+      including a fake gethostbyname() that interfaces to the fake DNS resolver
+      (see PH/47 above).
+
+TF/06 The fix for widen_domains has also been applied to qualify_single and
+      search_parents which are the other dnslookup options that can cause
+      header rewrites.
+
+PH/49 Michael Haardt's randomized retrying, but as a separate retry parameter
+      type ("H").
+
+PH/50 Make never_users, trusted_users, admin_groups, trusted_groups expandable.
+
+TF/07 Exim produced the error message "an SRV record indicated no SMTP
+      service" if it encountered an MX record with an empty target hostname.
+      The message is now "an MX or SRV record indicated no SMTP service".
+
+TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
+      if the DNS of the sending site is misconfigured. This is quite a
+      common situation. This change restores the behaviour of treating a
+      helo verification defer as a failure.
