CHANGES

4425.	[bug]		arpaname and dnstap-read were not being installed
			into ${prefix}/bin.  Tidy up installation issues
			with CHANGE 4421. [RT #42910]

4424.	[experimental]	Named now sends _ta-XXXX.<trust-anchor>/NULL queries
			to provide feedback to the trust-anchor administrators
			about how key rollovers are progressing as per
			draft-ietf-dnsop-edns-key-tag-02.  This can be
			disabled using 'trust-anchor-telemetry no;'.
			[RT #40583]

4423.	[maint]		Added missing IPv6 address 2001:500:84::b for
			B.ROOT-SERVERS.NET. [RT #42898]

4422.	[port]		Silence clang warnings in dig.c and dighost.c.
			[RT #42451]

4421.	[func]		When built with LMDB (Lightning Memory-mapped
			Database), named will now use a database to store
			the configuration for zones added by "rndc addzone"
			instead of using a flat NZF file. This improves
			performance of "rndc delzone" and "rndc modzone"
			significantly. Existing NZF files will
			automatically by converted to NZD databases.
			To view the contents of an NZD or to roll back to
			NZF format, use "named-nzd2nzf". To disable
			this feature, use "configure --without-lmdb".
			[RT #39837]

			prefixes or 128 for v6 prefixes. In addition to
			fixing this, "dig +subnet=0" has been added as a
			short form for 0.0.0.0/0. The same changes have

			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
			representation and returns ISC_R_NOTIMPLEMENTED,
			such RDATA is now printed in unknown
			presentation format (RFC 3597). RR types affected
			include LOC(29) and APL(42). [RT #40317].

4186.	[bug]		Fixed an RPZ bug where a QNAME would be matched
			against a policy RR with wildcard owner name
			(trigger) where the QNAME was the wildcard owner
			name's parent. For example, the bug caused a query
			with QNAME "example.com" to match a policy RR with
			"*.example.com" as trigger. [RT #40357]

4185.	[bug]		Fixed an RPZ bug where a policy RR with wildcard
			owner name (trigger) would prevent another policy RR

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

4123.	[port]		Added %z (size_t) format options to the portable
			internal printf/sprintf implementation. [RT #39586]

4122.	[bug]		The server could match a shorter prefix than what was
			available in CLIENT-IP policy triggers, and so, an
			unexpected action could be taken. This has been
			corrected. [RT #39481]

4121.	[bug]		On servers with one or more policy zones
			configured as slaves, if a policy zone updated
			during regular operation (rather than at
			startup) using a full zone reload, such as via
			AXFR, a bug could allow the RPZ summary data to
			fall out of sync, potentially leading to an
			assertion failure in rpz.c when further
