+ 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 cannot be turned off.
