 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.

       (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.
+
+64. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
+    This has been fixed.
+
+65. Caching of lookup data for "hosts =" ACL conditions, when a named host list
+    was in use, was not putting the data itself into the right store pool;
+    consequently, it could be overwritten for a subsequent message in the same
+    SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
+    the caching.)
+
+66. Added hosts_max_try_hardlimit to the smtp transport, default 50.
+
+67. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
+    address", "IPv4 address", and "IPv6 address", respectively. Some calls of
+    the function were treating the return as a boolean value, which happened to
+    work because 0=false and not-0=true, but is not correct code.
+
+68. The host_aton() function was not handling scoped IPv6 addresses (those
+    with, for example, "%eth0" on the end) correctly.
+
+69. Fixed some compiler warnings in acl.c for the bitmaps specified with
+    negated items (that is, ~something) in unsigned ints. Some compilers
+    apparently mutter when there is no cast.
+
+70. If an address verification called from an ACL failed, and did not produce a
+    user-specific message (i.e. there was only a "system" message), nothing was
+    put in $acl_verify_message. In this situation, it now puts the system
+    message there.
