 Change log file for Exim from version 4.21
 -------------------------------------------
 
+Exim version 4.68
+-----------------
+
+PH/01 Another patch from the Sieve maintainer.
+
+PH/02 When an IPv6 address is converted to a string for single-key lookup
+      in an address list (e.g. for an item such as "net24-dbm;/net/works"),
+      dots are used instead of colons so that keys in lsearch files need not
+      contain colons. This was done some time before quoting was made available
+      in lsearch files. However, iplsearch files do require colons in IPv6 keys
+      (notated using the quote facility) so as to distinguish them from IPv4
+      keys. This meant that lookups for IP addresses in host lists did not work
+      for iplsearch lookups.
+
+      This has been fixed by arranging for IPv6 addresses to be expressed with
+      colons if the lookup type is iplsearch. This is not incompatible, because
+      previously such lookups could never work.
+
+      The situation is now rather anomolous, since one *can* have colons in
+      ordinary lsearch keys. However, making the change in all cases is
+      incompatible and would probably break a number of configurations.
+
+TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
+      version.
+
+MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
+      conversion specification without a maximum field width, thereby enabling
+      a rogue spamd server to cause a buffer overflow. While nobody in their
+      right mind would setup Exim to query an untrusted spamd server, an
+      attacker that gains access to a server running spamd could potentially
+      exploit this vulnerability to run arbitrary code as the Exim user.
