 Change log file for Exim from version 4.21

@@ -148,6 +148,24 @@ PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
       Document more things not specified clearly in RFC3028.  I had all this
       sorted out, when out of a sudden new issues came to my mind.  Oops."
 
+PH/18 Exim was not recognizing the "net-" search type prefix in match_ip lists
+      (Bugzilla #53).
+
+PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
+      canonical form (as documented). However, after a host name lookup from
+      the IP address, check_host() was doing a simple string comparison with
+      addresses acquired from the DNS when checking that the found name did
+      have the original IP as one of its addresses. Since any found IPv6
+      addresses are likely to be in abbreviated form, the comparison could
+      fail. Luckily, there already exists a function for doing the comparison
+      by converting both addresses to binary, so now that is used instead of
+      the text comparison.
+
+PH/20 There was another similar case to PH/19, when a complete host name was
+      given in a host list; looking up its IP address could give an abbreviated
+      form, whereas the current host's name might or might not be abbreviated.
+      The same fix has been applied.
