+53. Now that there can be additional text after "Completed" in log lines (if
+    the queue_time_overall log selector is set), a one-byte patch to exigrep
+    was needed to allow it to recognize "Completed" as not the last thing in
+    the line.
+
+54. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
+    patch that reportedly fixes this has been added. I am not expert enough to
+    create a test for it. This is what the patch creator wrote:
+
+      "I found a little strange behaviour of ldap code when working with
+      Windows 2003 AD Domain, where users was placed in more than one
+      Organization Units. When I tried to give exim partial DN, the exit code
+      of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
+      But simultaneously result of request was absolutely normal ldap result,
+      so I produce this patch..."
+
+55. Some experimental protocols are using DNS PTR records for new purposes. The
+    keys for these records are domain names, not reversed IP addresses. The
+    dnsdb PTR lookup now tests whether its key is an IP address. If not, it
+    leaves it alone. Component reversal etc. now happens only for IP addresses.
+
+56. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
+
+57. Double the size of the debug message buffer (to 2048) so that more of very
+    long debug lines gets shown.
+
+58. The exicyclog utility now does better if the number of log files to keep
+    exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
+
+59. Two changes related to the smtp_active_hostname option:
+
+      (1) $smtp_active_hostname is now available as a variable.
+      (2) The default for smtp_banner uses $smtp_active_hostname instead
+          of $primary_hostname.
+
+60. The host_aton() function is supposed to be passed a string that is known
+    to be a valid IP address. However, in the case of IPv6 addresses, it was
+    not checking this. This is a hostage to fortune. Exim now panics and dies
+    if the condition is not met. A case was found where this could be provoked
+    from a dnsdb lookup; fortuitously, this particular loophole had already
+    been fixed by change 4.50/55 above. If there are any other similar
+    loopholes, the new check should stop them being exploited.
+
