+- Catalog Zones schema version 2, as described in the "DNS Catalog Zones" IETF
+  draft version 5 document, is now supported by :iscman:`named`. All of the
+  previously supported BIND-specific catalog zone custom properties
+  (``primaries``, ``allow-query``, and ``allow-transfer``), as well as the new
+  Change of Ownership (``coo``) property, are now implemented. Schema version 1
+  is still supported, with some additional validation rules applied from
+  schema version 2: for example, the ``version`` property is mandatory, and a
+  member zone PTR RRset must not contain more than one record. In the event of a
+  validation error, a corresponding error message is logged to help with
+  diagnosing the problem. :gl:`#3221` :gl:`#3222` :gl:`#3223` :gl:`#3224`
