 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 lookup now tests whether it's key is an IP address. If not, it leaves
-    it alone. Component reversal etc. now happens only for IP addresses.

 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.
