+ o BIND_OPTIONS, FORWARD and SLAVE are gone. Just write the
+ options to the parent config file. (If you think it is somewhat
+ inconvenient, ask BIND developers to change the config file
+ parser, so that multiple options { } sections can be specified.)
+ o Root hints became optional. If you want them, use ROOTHINT().
+
+ Furthermore, several features have been added:
+
+ o A FORWARDING macro for generating forward-only zones.
+ o A BLACKHOLE macro for blackhole zones as per RFC 6303.
+ Blackhole zones in example cf/domains updated to use this macro.
+ o When contents of a zone do not change, the version number is
+ not incremented. Unfortunately, BIND tends to produce a warning
+ in such cases, and it be turned off.
+
+Version 3.1 [2008-05-21]
+
+ o Fixes for compatibility problems with recent versions of GNU m4.
+ o Added support for TXT, RP and SRV records.
+
+Version 3.0.1 [2006-11-22]
+
+ Fixed bugs in in the FORWARD and SLAVE macros, causing it to
+ generate bogus output sometimes.
