+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 PTR lookup with an IPv6 address that had more than 8
+    components; fortuitously, this particular loophole had already been fixed
+    by change 4.50/55 above.
+
+    If there are any other similar loopholes, the new check in host_aton()
+    itself should stop them being exploited. The report I received stated that
+    data on the command line could provoke the exploit when Exim was running as
+    exim, but did not say which command line option was involved. All I could
+    find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
+    running as the user.
+
+61. There was a buffer overflow vulnerability in the SPA authentication code
+    (which came originally from the Samba project). I have added a test to the
+    spa_base64_to_bits() function which I hope fixes it.
+
+62. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
+    os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
+
+63. The daemon start-up calls getloadavg() while still root for those OS that
+    need the first call to be done as root, but it missed one case: when
+    deliver_queue_load_max is set with deliver_drop_privilege. This is
+    necessary for the benefit of the queue runner, because there is no re-exec
+    when deliver_drop_privilege is set.
