			while taking advantage of advanced database
			features not available in BIND such as multi-master
			replication.

			Thanks to Adam Tkac and Petr Spacek of Red Hat.

4187.	[func]		When any RR type implementation doesn't
			implement totext() for the RDATA's wire

4186.	[bug]		Fixed an RPZ bug where a QNAME would be matched
			against a policy RR with wildcard owner name

			owner name (trigger) would prevent another policy RR
			with its parent owner name from being

			"*.example.com" existed in that RPZ zone.
