+Version 5.0 [2019-01-30]
+
+ Added support for DNSSEC. See section 8 of README.
+
+ It turned out that configurability of directory names (e.g., HASHDIR)
+ was incomplete and it made all scripts unnecessarily complicated.
+ We replaced the configuration variables by hard-coded names equal
+ to the previous default settings which hopefully nobody ever needed
+ to change.
+
+ Also, ROOTHINT() became obsolete as BIND packages now regularly come
+ with a well updated root hint file. Please set up the root hints in
+ the master bind configuration file before you include named.conf
+ generated by NSC.
+
+Version 4.0 [2011-10-22]
+
+ This version brings several incompatible changes with a common
+ goal: instead of generating a full named.conf, produce a fragment
+ which can be included from a parent config file.
+
+ 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.
+
+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.
+
+Version 3.0 [2005-02-20]
+
+ One year of testing should be good enough, so releasing 2.99b as 3.0
+ with almost no changes. The only one is:
+
+ o ZONE_OPTIONS macro added, allowing to add custom options to zones.
