			times.

4272.	[bug]		dig: the +norrcomments option didn't work with +multi.
			[RT #41234]

4271.	[test]		Unit tests could deadlock in isc__taskmgr_pause().
			[RT #41235]

4270.	[security]	Update allowed OpenSSL versions as named is
			potentially vulnerable to CVE-2015-3193.

4269.	[bug]		Zones using "map" format master files currently
			don't work as policy zones.  This limitation has
			now been documented; attempting to use such zones
			in "response-policy" statements is now a
			configuration error.  [RT #38321]

4268.	[func]		"rndc status" now reports the path to the
			configuration file. [RT #36470]

4267.	[test]		Check sdlz error handling. [RT #41142]

4266.	[placeholder]

			[RT #41067]

4261.	[maint]		H.ROOT-SERVERS.NET is 198.97.190.53 and 2001:500:1::53.
			[RT #40556]

4260.	[security]	Insufficient testing when parsing a message allowed
			records with an incorrect class to be be accepted,
			triggering a REQUIRE failure when those records
			were subsequently cached. (CVE-2015-8000) [RT #40987]

4259.	[func]		Add an option for non-destructive control channel
			access using a "read-only" clause. In such
			cases, a restricted set of rndc commands are
			allowed for querying information from named.
			[RT #40498]

4258.	[bug]		Limit rndc query message sizes to 32 KiB. This should
			not break any legitimate rndc commands, but will
			prevent a rogue rndc query from allocating too
			much memory. [RT #41073]

4257.	[cleanup]	Python scripts reported incorrect version. [RT #41080]

4256.	[bug]		Allow rndc command arguments to be quoted so as
			to allow spaces. [RT #36665]

4255.	[performance]	Add 'message-compression' option to disable DNS
			compression in responses. [RT #40726]

4254.	[bug]		Address missing lock when getting zone's serial.

			[RT #37556]

4238.	[bug]		Don't send to servers on net zero (0.0.0.0/8).
			[RT #40947]

4237.	[doc]		Upgraded documentation toolchain to use DocBook 5
			and dblatex. [RT #40766]

4236.	[performance]	On machines with 2 or more processors (CPU), the
			default value for the number of UDP listeners
			has been changed to the number of detected
			processors minus one. [RT #40761]

4235.	[func]		Added support in named for "dnstap", a fast method of
			capturing and logging DNS traffic, and a new command
			"dnstap-read" to read a dnstap log file.  Use
			"configure --enable-dnstap" to enable this
			feature (note that this requires libprotobuf-c
			and libfstrm). See the ARM for configuration details.

			Thanks to Robert Edmonds of Farsight Security.
			[RT #40211]

4234.	[func]		Add deflate compression in statistics channel HTTP

4225.	[port]		freebsd/openbsd:  Use '${CC} -shared' for building
			shared libraries. [RT #39557]

4224.	[func]		Added support for "dyndb", a new interface for loading
			zone data from an external database, developed by
			Red Hat for the FreeIPA project.

			DynDB drivers fully implement the BIND database
			API, and are capable of significantly better
			performance and functionality than DLZ drivers,
			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.
			[RT #35271]

			to and from unknown-type format. [RT #40584]

4202.	[bug]		isccc_cc_fromwire() could return an incorrect
			result. [RT #40614]

4201.	[func]		The default preferred-glue is now the address record
			type of the transport the query was received
			over.  [RT #40468]

			as per RFC 6763. [RT #37889]

4190.	[protocol]	Accept Active Directory gc._msdcs.<forest> name as
			valid with check-names.  <forest> still needs to be
			LDH. [RT #40399]

4189.	[cleanup]	Don't exit on overly long tokens in named.conf.
			[RT #40418]

4188.	[bug]		Support HTTP/1.0 client properly on the statistics
			channel. [RT #40261]

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

			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
			incremental updates were made to the zone, such
			as via IXFR. [RT #39567]

4120.	[bug]		A bug in RPZ could cause the server to crash if

4115.	[func]		"rndc -r" now prints the result code (e.g.,
			ISC_R_SUCCESS, ISC_R_TIMEOUT, etc) after
			running the requested command. [RT #38913]

4094.	[bug]		A race during shutdown or reconfiguration could
			cause an assertion in mem.c. [RT #38979]

4093.	[func]		Dig now learns the SIT value from truncated

4092.	[bug]		'in-view' didn't work for zones beneath a empty zone.
			[RT #39173]

4091.	[cleanup]	Some cleanups in isc mem code. [RT #38896]

4090.	[bug]		Fix a crash while parsing malformed CAA RRs in
			presentation format, i.e., from text such as
			from master files. Thanks to John Van de
			Meulebrouck Brendgard for discovering and
			reporting this problem. [RT #39003]

4085.	[bug]		ISC_PLATFORM_HAVEXADDQ could be inconsistently set.
			[RT #38828]

4084.	[bug]		Fix a possible race in updating stats counters.
			[RT #38826]

4083.	[cleanup]	Print the number of CPUs and UDP listeners
			consistently in the log and in "rndc status"
			output; indicate whether threads are supported
			in "named -V" output. [RT #38811]

4082.	[bug]		Incrementally sign large inline zone deltas.
			[RT #37927]

4081.	[cleanup]	Use dns_rdatalist_init consistently. [RT #38759]

4080.	[func]		Completed change #4022, adding a "lock-file" option
			to named.conf to override the default lock file,
			in addition to the "named -X <filename>" command
			line option.  Setting the lock file to "none"
			using either method disables the check completely.
			[RT #37908]

4079.	[func]		Preserve the case of the owner name of records to
			the RRset level. [RT #37442]

4078.	[bug]		Handle the case where CMSG_SPACE(sizeof(int)) !=

4075.	[placeholder]

4074.	[cleanup]	Cleaned up more warnings from gcc -Wshadow. [RT #38708]

4073.	[cleanup]	Add libjson-c version number reporting to
			"named -V"; normalize version number formatting.
			[RT #38056]

4072.	[func]		Add a --enable-querytrace configure switch for
			very verbose query trace logging. (This option
			has a negative performance impact and should be
			used only for debugging.) [RT #37520]

4071.	[cleanup]	Initialize pthread mutex attrs just once, instead of
			doing it per mutex creation. [RT #38547]

4070.	[bug]		Fix a segfault in nslookup in a query such as
			"nslookup isc.org AMS.SNS-PB.ISC.ORG -all".
			[RT #38548]

			[RT #38515]

4068.	[bug]		Omit unknown serial number from JSON zone statistics.
			[RT #38604]

4067.	[cleanup]	Reduce noise from RRL when query logging is
			disabled. [RT #38648]

4066.	[doc]		Reorganize options in the dig man page. [RT #38516]

4065.	[test]		Additional RFC 5011 tests. [RT #38569]

4064.	[contrib]	dnssec-keyset.sh: Generates a specified number
			of DNSSEC keys with timing set to implement a
			pre-publication key rollover strategy. Thanks
			to Jeffry A. Spain. [RT #38459]

4063.	[bug]		Asynchronous zone loads were not handled
			correctly when the zone load was already in
			progress; this could trigger a crash in zt.c.
			[RT #37573]

4062.	[bug]		Fix an out-of-bounds read in RPZ code. If the
			read succeeded, it doesn't result in a bug
			during operation. If the read failed, named
			could segfault. [RT #38559]

4061.	[bug]		Handle timeout in legacy system test. [RT #38573]

4060.	[bug]		dns_rdata_freestruct could be called on a
			uninitialized structure when handling a error.
			[RT #38568]

4059.	[bug]		Addressed valgrind warnings. [RT #38549]

4058.	[bug]		UDP dispatches could use the wrong pseudorandom
			number generator context. [RT #38578]

4057.	[bug]		'dnssec-dsfromkey -T 0' failed to add ttl field.
			[RT #38565]

4056.	[bug]		Expanded automatic testing of trust anchor
			management and fixed several small bugs including
			a memory leak and a possible loss of key state
			information. [RT #38458]

4055.	[func]		"rndc managed-keys" can be used to check status
			of trust anchors or to force keys to be refreshed,
			Also, the managed keys data file has easier-to-read
			comments.  [RT #38458]

4054.	[func]		Added a new tool 'mdig', a light weight clone of
			dig able to send multiple pipelined queries.
			[RT #38261]

4053.	[security]	Revoking a managed trust anchor and supplying
			an untrusted replacement could cause named
			to crash with an assertion failure.
			(CVE-2015-1349) [RT #38344]

4052.	[bug]		Fix a leak of query fetchlock. [RT #38454]

4051.	[bug]		Fix a leak of pthread_mutexattr_t. [RT #38454]

4050.	[bug]		RPZ could send spurious SERVFAILs in response
			to duplicate queries. [RT #38510]

4049.	[bug]		CDS and CDNSKEY had the wrong attributes. [RT #38491]

4048.	[bug]		adb hash table was not being grown. [RT #38470]

4047.	[cleanup]	"named -V" now reports the current running versions
			of OpenSSL and the libxml2 libraries, in addition to
			the versions that were in use at build time.

4046.	[bug]		Accounting of "total use" in memory context
			statistics was not correct. [RT #38370]

4045.	[bug]		Skip to next master on dns_request_createvia4 failure.
			[RT #25185]

4044.	[bug]		Change 3955 was not complete, resulting in an assertion
			failure if the timing was just right. [RT #38352]

4043.	[func]		"rndc modzone" can be used to modify the
			configuration of an existing zone, using similar
			syntax to "rndc addzone". [RT #37895]

4042.	[bug]		zone.c:iszonesecure was being called too late.
			[RT #38371]

4041.	[func]		TCP sockets can now be shared while connecting.
			(This will be used to enable client-side support
			of pipelined queries.) [RT #38231]

4040.	[func]		Added server-side support for pipelined TCP
			queries. Clients may continue sending queries via
			TCP while previous queries are being processed
			in parallel.  (The new "keep-response-order"
			option allows clients to be specified for which
			the old behavior will still be used.) [RT #37821]

4039.	[cleanup]	Cleaned up warnings from gcc -Wshadow. [RT #37381]

4038.	[bug]		Add 'rpz' flag to node and use it to determine whether
			to call dns_rpz_delete.  This should prevent unbalanced
			add / delete calls. [RT #36888]

4037.	[bug]		also-notify was ignoring the tsig key when checking
			for duplicates resulting in some expected notify
			messages not being sent. [RT #38369]

4036.	[bug]		Make call to open a temporary file name safe during
			NZF creation. [RT #38331]

4035.	[bug]		Close temporary and NZF FILE pointers before moving
			the former into the latter's place, as required on
			Windows. [RT #38332]

4034.	[func]		When added, negative trust anchors (NTA) are now
			saved to files (viewname.nta), in order to
			persist across restarts of the named server.
			[RT #37087]

4033.	[bug]		Missing out of memory check in request.c:req_send.
			[RT #38311]

4032.	[bug]		Built-in "empty" zones did not correctly inherit the
			"allow-transfer" ACL from the options or view.
			[RT #38310]

4031.	[bug]		named-checkconf -z failed to report a missing file
			with a hint zone. [RT #38294]

4030.	[func]		"rndc delzone" is now applicable to zones that were
			configured in named.conf, as well as zones that
			were added via "rndc addzone". (Note, however, that
			if named.conf is not also modified, the deleted zone
			will return when named is reloaded.) [RT #37887]

4029.	[func]		"rndc showzone" displays the current configuration
			of a specified zone. [RT #37887]

4028.	[bug]		$GENERATE with a zero step was not being caught as a
			error.  A $GENERATE with a / but no step was not being
			caught as a error. [RT #38262]

4027.	[port]		Net::DNS 0.81 compatibility. [RT #38165]

4026.	[bug]		Fix RFC 3658 reference in dig +sigchase. [RT #38173]

4025.	[port]		bsdi: failed to build. [RT #38047]

4024.	[bug]		dns_rdata_opt_first, dns_rdata_opt_next,
			dns_rdata_opt_current, dns_rdata_txt_first,
			dns_rdata_txt_next and dns_rdata_txt_current were
			documented but not implemented.  These have now been
			implemented.

			dns_rdata_spf_first, dns_rdata_spf_next and
			dns_rdata_spf_current were documented but not
			implemented.  The prototypes for these
			functions have been removed. [RT #38068]

4023.	[bug]		win32: socket handling with explicit ports and
			invoking named with -4 was broken for some
			configurations. [RT #38068]

4022.	[func]		Stop multiple spawns of named by limiting number of
			processes to 1. This is done by using a lockfile and
			checking whether we can listen on any configured
			TCP interfaces. [RT #37908]

4021.	[bug]		Adjust max-recursion-queries to accommodate
			the need for more queries when the cache is
			empty. [RT #38104]

4020.	[bug]		Change 3736 broke nsupdate's SOA MNAME discovery
			resulting in updates being sent to the wrong server.
			[RT #37925]

4019.	[func]		If named is not configured to validate the answer
			then allow fallback to plain DNS on timeout even
			when we know the server supports EDNS. [RT #37978]

4018.	[placeholder]

4017.	[test]		Add system test to check lookups to legacy servers
			with broken DNS behavior. [RT #37965]

4016.	[bug]		Fix a dig segfault due to bad linked list usage.
			[RT #37591]

4015.	[bug]		Nameservers that are skipped due to them being
			CNAMEs were not being logged. They are now logged
			to category 'cname' as per BIND 8. [RT #37935]

4014.	[bug]		When including a master file origin_changed was
			not being properly set leading to a potentially
			spurious 'inherited owner' warning. [RT #37919]

4013.	[func]		Add a new tcp-only option to server (config) /
			peer (struct) to use TCP transport to send
			queries (in place of UDP transport with a
			TCP fallback on truncated (TC set) response).
			[RT #37800]

4012.	[cleanup]	Check returned status of OpenSSL digest and HMAC
			functions when they return one. Note this applies
			only to FIPS capable OpenSSL libraries put in
			FIPS mode and MD5. [RT #37944]

4011.	[bug]		master's list port and dscp inheritance was not
			properly implemented. [RT #37792]

4010.	[cleanup]	Clear the prefetchable state when initiating a
			prefetch. [RT #37399]

4009.	[func]		delv: added a +tcp option. [RT #37855]

4008.	[contrib]	Updated zkt to latest version (1.1.3). [RT #37886]

4007.	[doc]		Remove acl forward reference restriction. [RT #37772]

4006.	[security]	A flaw in delegation handling could be exploited
			to put named into an infinite loop.  This has
			been addressed by placing limits on the number
			of levels of recursion named will allow (default 7),
			and the number of iterative queries that it will
			send (default 50) before terminating a recursive
			query (CVE-2014-8500).

			The recursion depth limit is configured via the
			"max-recursion-depth" option, and the query limit
			via the "max-recursion-queries" option.  [RT #37580]

4005.	[func]		The buffer used for returning text from rndc
			commands is now dynamically resizable, allowing
			arbitrarily large amounts of text to be sent back
			to the client. (Prior to this change, it was
			possible for the output of "rndc tsig-list" to be
			truncated.) [RT #37731]

4004.	[bug]		When delegations had AAAA glue but not A, a
			reference could be leaked causing an assertion
			failure on shutdown. [RT #37796]

4003.	[security]	When geoip-directory was reconfigured during
			named run-time, the previously loaded GeoIP
			data could remain, potentially causing wrong
			ACLs to be used or wrong results to be served
			based on geolocation (CVE-2014-8680). [RT #37720]

4002.	[security]	Lookups in GeoIP databases that were not
			loaded could cause an assertion failure
			(CVE-2014-8680). [RT #37679]

4001.	[security]	The caching of GeoIP lookups did not always
			handle address families correctly, potentially
			resulting in an assertion failure (CVE-2014-8680).
			[RT #37672]

4000.	[bug]		NXDOMAIN redirection incorrectly handled NXRRSET
			from the redirect zone. [RT #37722]

3999.	[func]		"mkeys" and "nzf" files are now named after
			their corresponding views, unless the view name
			contains characters that would be incompatible
			with use in a filename (i.e., slash, backslash,
			or capital letters). If a view name does contain
			these characters, the files will still be named
			using a cryptographic hash of the view name.
			Regardless of this, if a file using the old name
			format is found to exist, it will continue to be
			used. [RT #37704]
