	--- 9.16.3 released ---

5404.	[bug]		'named-checkconf -z' could incorrectly indicate
			success if errors were found in one view but not in a
			subsequent one. [GL #1807]

5403.	[func]		Do not set UDP receive/send buffer sizes - use system
			defaults. [GL #1713]

5402.	[bug]		On FreeBSD, use SO_REUSEPORT_LB instead of SO_REUSEPORT.
			Enable use of SO_REUSEADDR on all platforms which
			support it. [GL !3365]

5401.	[bug]		The number of input queues allocated during dnstap
			initialization was too low, which could prevent some
			dnstap data from being logged. [GL #1795]

5400.	[func]		Add engine support to OpenSSL EdDSA implementation.
			[GL #1763]

5399.	[func]		Add engine support to OpenSSL ECDSA implementation.
			[GL #1534]

5398.	[bug]		Named could fail to restart if a zone with a double
			quote (") in its name was added with 'rndc addzone'.
			[GL #1695]

5397.	[func]		Update PKCS#11 EdDSA implementation to PKCS#11 v3.0.
			Thanks to Aaron Thompson. [GL !3326]

5396.	[func]		When necessary (i.e. in libuv >= 1.37), use the
			UV_UDP_RECVMMSG flag to enable recvmmsg() support in
			libuv. [GL #1797]

5395.	[security]	Further limit the number of queries that can be
			triggered from a request.  Root and TLD servers
			are no longer exempt from max-recursion-queries.
			Fetches for missing name server address records
			are limited to 4 for any domain. (CVE-2020-8616)
			[GL #1388]

5394.	[cleanup]	Named formerly attempted to change the effective UID and
			GID in named_os_openfile(), which could trigger a
			spurious log message if they were already set to the
			desired values. This has been fixed. [GL #1042]
			[GL #1090]

5392.	[bug]		It was possible for named to crash during shutdown
			or reconfiguration if an RPZ zone was still being
			updated. [GL #1779]

5390.	[security]	Replaying a TSIG BADTIME response as a request could
			trigger an assertion failure. (CVE-2020-8617)
			[GL #1703]

5389.	[bug]		Finish PKCS#11 code cleanup, fix a couple of smaller
			bugs and use PKCS#11 v3.0 EdDSA macros and constants.
			Thanks to Aaron Thompson. [GL !3391]

5387.	[func]		Warn about AXFR streams with inconsistent message IDs.
			[GL #1674]

5386.	[cleanup]	Address Coverity warnings in lib/dns/keymgr.c.
			[GL #1737]

5385.	[func]		Make ISC rwlock implementation the default again.
			[GL #1753]

5384.	[bug]		With "dnssec-policy" in effect, "inline-signing" was
			implicitly set to "yes". Now "inline-signing" is only
			set to "yes" if the zone is not dynamic. [GL #1709]

	--- 9.16.2 released ---

5383.	[func]		Add a quota attach function with a callback and clean up
			the isc_quota API. [GL !3280]

5382.	[bug]		Use clock_gettime() instead of gettimeofday() for
			isc_stdtime() function. [GL #1679]

5381.	[bug]		Fix logging API data race by adding rwlock and caching
			logging levels in stdatomic variables to restore
			performance to original levels. [GL #1675] [GL #1717]

5380.	[contrib]	Fix building MySQL DLZ modules against MySQL 8
			libraries. [GL #1678]

5378.	[bug]		Receiving invalid DNS data was triggering an assertion
			failure in nslookup. [GL #1652]

5376.	[bug]		Fix ineffective DNS rebinding protection when BIND is
			configured as a forwarding DNS server. Thanks to Tobias
			Klein. [GL #1574]

5375.	[test]		Fix timing issues in the "kasp" system test. [GL #1669]

5374.	[bug]		Statistics counters tracking recursive clients and
			active connections could underflow. [GL #1087]

5373.	[bug]		Collecting statistics for DNSSEC signing operations
			(change 5254) caused an array of significant size (over
			100 kB) to be allocated for each configured zone. Each
			of these arrays is tracking all possible key IDs; this
			could trigger an out-of-memory condition on servers with
			a high enough number of zones configured. Fixed by
			tracking up to four keys per zone and rotating counters
			when keys are replaced. This fixes the immediate problem
			of high memory usage, but should be improved in a future
			release by growing or shrinking the number of keys to
			track upon key rollover events. [GL #1179]

5372.	[bug]		Fix migration from existing DNSSEC key files
			("auto-dnssec maintain") to "dnssec-policy". [GL #1706]

5371.	[bug]		Improve incremental updates of the RPZ summary
			database to reduce delays that could occur when
			a policy zone update included a large number of
			record deletions. [GL #1447]

5370.	[bug]		Deactivation of a netmgr handle associated with a
			socket could be skipped in some circumstances.
			Fixed by deactivating the netmgr handle before
			scheduling the asynchronous close routine. [GL #1700]

5368.	[bug]		Named failed to restart if 'rndc addzone' names
			contained special characters (e.g. '/'). [GL #1655]

5367.	[bug]		Fixed a flaw in the calculation of the zone database
			size so that "max-journal-size default" uses the correct
			limit. [GL #1661]

	--- 9.16.1 released ---

5366.	[bug]		Fix a race condition with the keymgr when the same
			zone plus dnssec-policy is configured in multiple
			views. [GL #1653]

5365.	[bug]		Algorithm rollover was stuck on submitting DS
			because keymgr thought it would move to an invalid
			state.  Fixed by checking the current key against
			the desired state, not the existing state. [GL #1626]

5364.	[bug]		Algorithm rollover waited too long before introducing
			zone signatures.  It waited to make sure all signatures
			were regenerated, but when introducing a new algorithm,
			all signatures are regenerated immediately.  Only
			add the sign delay if there is a predecessor key.
			[GL #1625]

5363.	[bug]		When changing a dnssec-policy, existing keys with
			properties that no longer match were not being retired.
			[GL #1624]

5361.	[bug]		named might not accept new connections after
			hitting tcp-clients quota. [GL #1643]

5360.	[bug]		delv could fail to load trust anchors in DNSKEY
			format. [GL #1647]

5358.	[bug]		Inline master zones whose master files were touched
			but otherwise unchanged and were subsequently reloaded
			may have stopped re-signing. [GL !3135]

5357.	[bug]		Newly added RRSIG records with expiry times before
			the previous earliest expiry times might not be
			re-signed in time.  This was a side effect of 5315.
			[GL !3137]

	--- 9.16.0 released ---

5356.	[func]		Update dnssec-policy configuration statements:
			- Rename "zone-max-ttl" dnssec-policy option to
			  "max-zone-ttl" for consistency with the existing
			  zone option.
			- Allow for "lifetime unlimited" as a synonym for
			  "lifetime PT0S".
			- Make "key-directory" optional.
			- Warn if specifying a key length does not make
			  sense; fail if key length is out of range for
			  the algorithm.
			- Allow use of mnemonics when specifying key
			  algorithm (e.g. "rsasha256", "ecdsa384", etc.).
			- Make ISO 8601 durations case-insensitive.
			[GL #1598]

5355.	[func]		What was set with --with-tuning=large option in
			older BIND9 versions is now a default, and
			a --with-tuning=small option was added for small
			(e.g. OpenWRT) systems. [GL !2989]

5354.	[bug]		dnssec-policy created new KSK keys for zones in the
			initial stage of signing (with the DS not yet in the
			rumoured or omnipresent states).  Fix by checking the
			key goals rather than the active state when determining
			whether new keys are needed. [GL #1593]

5353.	[doc]		Document port and dscp parameters in forwarders
			configuration option. [GL #914]

5352.	[bug]		Correctly handle catalog zone entries containing
			characters that aren't legal in filenames. [GL #1592]

5351.	[bug]		CDS / CDNSKEY consistency checks failed to handle
			removal records. [GL #1554]

5350.	[bug]		When a view was configured with class CHAOS, the
			server could crash while processing a query for a
			non-existent record. [GL #1540]

5349.	[bug]		Fix a race in task_pause/unpause. [GL #1571]

5348.	[bug]		dnssec-settime -Psync was not being honoured.
			[GL !2925]

	--- 9.15.8 released ---

5347.	[bug]		Fixed a bug that could cause an intermittent crash
			in validator.c when validating a negative cache
			entry. [GL #1561]

5346.	[bug]		Make hazard pointer array allocations dynamic, fixing
			a bug that caused named to crash on machines with more
			than 40 cores. [GL #1493]

5345.	[func]		Key-style trust anchors and DS-style trust anchors
			can now both be used for the same name. [GL #1237]

5344.	[bug]		Handle accept() errors properly in netmgr. [GL !2880]

5343.	[func]		Add statistics counters to the netmgr. [GL #1311]

5342.	[bug]		Disable pktinfo for IPv6 and bind to each interface
			explicitly instead, because libuv doesn't support
			pktinfo control messages. [GL #1558]

5341.	[func]		Simplify passing the bound TCP socket to child
			threads by using isc_uv_export/import functions.
			[GL !2825]

5340.	[bug]		Don't deadlock when binding to a TCP socket fails.
			[GL #1499]

5339.	[bug]		With some libmaxminddb versions, named could erroneously
			match an IP address not belonging to any subnet defined
			in a given GeoIP2 database to one of the existing
			entries in that database. [GL #1552]

5338.	[bug]		Fix line spacing in `rndc secroots`.
			Thanks to Tony Finch. [GL !2478]

5337.	[func]		'named -V' now reports maxminddb and protobuf-c
			versions. [GL !2686]

	--- 9.15.7 released ---

5336.	[bug]		The TCP high-water statistic could report an
			incorrect value on startup. [GL #1392]

5335.	[func]		Make TCP listening code multithreaded. [GL !2659]

5334.	[doc]		Update documentation with dnssec-policy clarifications.
			Also change some defaults. [GL !2711]

5333.	[bug]		Fix duration printing on Solaris when value is not
			an ISO 8601 duration. [GL #1460]

5332.	[func]		Renamed "dnssec-keys" configuration statement
			to the more descriptive "trust-anchors". [GL !2702]

5331.	[func]		Use compiler-provided mechanisms for thread local
			storage, and make the requirement for such mechanisms
			explicit in configure. [GL #1444]

5330.	[bug]		'configure --without-python' was ineffective if
			PYTHON was set in the environment. [GL #1434]

5329.	[bug]		Reconfiguring named caused memory to be leaked when any
			GeoIP2 database was in use. [GL #1445]

5328.	[bug]		rbtdb.c:rdataset_{get,set}ownercase failed to obtain
			a node lock. [GL #1417]

5327.	[func]		Added a statistics counter to track queries
			dropped because the recursive-clients quota was
			exceeded. [GL #1399]

5326.	[bug]		Add Python dependency on 'distutils.core' to configure.
			'distutils.core' is required for installation.
			[GL #1397]

5325.	[bug]		Addressed several issues with TCP connections in
			the netmgr: restored support for TCP connection
			timeouts, restored TCP backlog support, actively
			close all open sockets during shutdown. [GL #1312]

5324.	[bug]		Change the category of some log messages from general
			to the more appropriate catergory of xfer-in. [GL #1394]

5323.	[bug]		Fix a bug in DNSSEC trust anchor verification.
			[GL !2609]

5322.	[placeholder]

5321.	[bug]		Obtain write lock before updating version->records
			and version->bytes. [GL #1341]

5320.	[cleanup]	Silence TSAN on header->count. [GL #1344]

	--- 9.15.6 released ---

5319.	[func]		Trust anchors can now be configured using DS
			format to represent a key digest, by using the
			new "initial-ds" or "static-ds" keywords in
			the "dnssec-keys" statement.

			Note: DNSKEY-format and DS-format trust anchors
			cannot both be used for the same domain name.
			[GL #622]

5318.	[cleanup]	The DNSSEC validation code has been refactored
			for clarity and to reduce code duplication.
			[GL #622]

5317.	[func]		A new asynchronous network communications system
			based on libuv is now used for listening for
			incoming requests and responding to them. (The
			old isc_socket API remains in use for sending
			iterative queries and processing responses; this
			will be changed too in a later release.)

			This change will make it easier to improve
			performance and implement new protocol layers
			(e.g., DNS over TLS) in the future. [GL #29]

5316.	[func]		A new "dnssec-policy" option has been added to
			named.conf to implement a key and signing policy
			(KASP) for zones. When this option is in use,
			named can generate new keys as needed and
			automatically roll both ZSK and KSK keys. (Note
			that the syntax for this statement differs from
			the dnssec policy used by dnssec-keymgr.)

			See the ARM for configuration details. [GL #1134]

5315.	[bug]		Apply the initial RRSIG expiration spread fixed
			to all dynamically created records in the zone
			including NSEC3. Also fix the signature clusters
			when the server has been offline for prolonged
			period of times. [GL #1256]

5314.	[func]		Added a new statistics variable "tcp-highwater"
			that reports the maximum number of simultaneous TCP
			clients BIND has handled while running. [GL #1206]

5313.	[bug]		The default GeoIP2 database location did not match
			the ARM.  'named -V' now reports the default
			location. [GL #1301]

5312.	[bug]		Do not flush the cache for `rndc validation status`.
			Thanks to Tony Finch. [GL !2462]

5311.	[cleanup]	Include all views in output of `rndc validation status`.
			Thanks to Tony Finch. [GL !2461]

5310.	[bug]		TCP failures were affecting EDNS statistics. [GL #1059]

5309.	[placeholder]

5308.	[bug]		Don't log DNS_R_UNCHANGED from sync_secure_journal()
			at ERROR level in receive_secure_serial(). [GL #1288]

5307.	[bug]		Fix hang when named-compilezone output is sent to pipe.
			Thanks to Tony Finch. [GL !2481]

5306.	[security]	Set a limit on number of simultaneous pipelined TCP
			queries. (CVE-2019-6477) [GL #1264]

5305.	[bug]		NSEC Aggressive Cache ("synth-from-dnssec") has been
			disabled by default because it was found to have
			a significant performance impact on the recursive
			service. [GL #1265]

5304.	[bug]		"dnskey-sig-validity 0;" was not being accepted.
			[GL #876]

5303.	[placeholder]

5302.	[bug]		Fix checking that "dnstap-output" is defined when
			"dnstap" is specified in a view. [GL #1281]

5301.	[bug]		Detect partial prefixes / incomplete IPv4 address in
			acls. [GL #1143]

5300.	[bug]		dig/mdig/delv: Add a colon after EDNS option names,
			even when the option is empty, to improve
			readability and allow correct parsing of YAML
			output. [GL #1226]

	--- 9.15.5 released ---

5299.	[security]	A flaw in DNSSEC verification when transferring
			mirror zones could allow data to be incorrectly
			marked valid. (CVE-2019-6475) [GL #1252]

5298.	[security]	Named could assert if a forwarder returned a
			referral, rather than resolving the query, when QNAME
			minimization was enabled. (CVE-2019-6476) [GL #1051]

5297.	[bug]		Check whether a previous QNAME minimization fetch
			is still running before starting a new one; return
			SERVFAIL and log an error if so. [GL #1191]

5296.	[placeholder]

5295.	[cleanup]	Split dns_name_copy() calls into dns_name_copy() and
			dns_name_copynf() for those calls that can potentially
			fail and those that should not fail respectively.
			[GL !2265]

5294.	[func]		Fallback to ACE name on output in locale, which does not
			support converting it to unicode.  [GL #846]

5293.	[bug]		On Windows, named crashed upon any attempt to fetch XML
			statistics from it. [GL #1245]

5292.	[bug]		Queue 'rndc nsec3param' requests while signing inline
			zone changes. [GL #1205]

	--- 9.15.4 released ---

5291.	[placeholder]

5290.	[placeholder]

5289.	[bug]		Address NULL pointer dereference in rpz.c:rpz_detach.
			[GL #1210]

5288.	[bug]		dnssec-must-be-secure was not always honored.
			[GL #1209]

5287.	[placeholder]

5286.	[contrib]	Address potential NULL pointer dereferences in
			dlz_mysqldyn_mod.c. [GL #1207]

5285.	[port]		win32: implement "-T maxudpXXX". [GL #837]

5284.	[func]		Added +unexpected command line option to dig.
			By default, dig won't accept a reply from a source
			other than the one to which it sent the query.
			Invoking dig with +unexpected argument will allow it
			to process replies from unexpected sources.

5283.	[bug]		When a response-policy zone expires, ensure that
			its policies are removed from the RPZ summary
			database. [GL #1146]

5282.	[bug]		Fixed a bug in searching for possible wildcard matches
			for query names in the RPZ summary database. [GL #1146]

5281.	[cleanup]	Don't escape commas when reporting named's command
			line. [GL #1189]

5280.	[protocol]	Add support for displaying EDNS option LLQ. [GL #1201]

5279.	[bug]		When loading, reject zones containing CDS or CDNSKEY
			RRsets at the zone apex if they would cause DNSSEC
			validation failures if published in the parent zone
			as the DS RRset.  [GL #1187]

5278.	[func]		Add YAML output formats for dig, mdig and delv;
			use the "+yaml" option to enable. [GL #1145]

	--- 9.15.3 released ---

5277.	[bug]		Cache DB statistics could underflow when serve-stale
			was in use, because of a bug in counter maintenance
			when RRsets become stale.

			Functions for dumping statistics have been updated
			to dump active, stale, and ancient statistic
			counters.  Ancient RRset counters are prefixed
			with '~'; stale RRset counters are still prefixed
			with '#'. [GL #602]

5276.	[func]		DNSSEC Lookaside Validation (DLV) is now obsolete;
			all code enabling its use has been removed from the
			validator, "delv", and the DNSSEC tools. [GL #7]

5275.	[bug]		Mark DS records included in referral messages
			with trust level "pending" so that they can be
			validated and cached immediately, with no need to
			re-query. [GL #964]

5274.	[bug]		Address potential use after free race when shutting
			down rpz. [GL #1175]

5273.	[bug]		Check that bits [64..71] of a dns64 prefix are zero.
			[GL #1159]

5272.	[cleanup]	Remove isc-config.sh script as the BIND 9 libraries
			are now purely internal. [GL #1123]

5271.	[func]		The normal (non-debugging) output of dnssec-signzone
			and dnssec-verify tools now goes to stdout, instead of
			the combination of stderr and stdout.

5270.	[bug]		'dig +expandaaaa +short' did not work. [GL #1152]

5269.	[port]		cygwin: can return ETIMEDOUT on connect() with a
			non-blocking socket. [GL #1133]

5268.	[placeholder]

5267.	[func]		Allow statistics groups display to be toggle-able.
			[GL #1030]

5266.	[bug]		named-checkconf failed to report dnstap-output
			missing from named.conf when dnstap was specified.
			[GL #1136]

5265.	[bug]		DNS64 and RPZ nodata (CNAME *.) rules interacted badly
			[GL #1106]

5264.	[func]		New DNS Cookie algorithm - siphash24 - has been added
			to BIND 9, and the old HMAC-SHA DNS Cookie algorithms
			have been removed. [GL #605]

	--- 9.15.2 released ---

5263.	[cleanup]	Use atomics and isc_refcount_t wherever possible.
			[GL #1038]

5262.	[func]		Removed support for the legacy GeoIP API. [GL #1112]

5261.	[cleanup]	Remove SO_BSDCOMPAT socket option usage.

5260.	[bug]		dnstap-read was producing malformed output for large
			packets. [GL #1093]

5259.	[func]		New option '-i' for 'named-checkconf' to ignore
			warnings about deprecated options. [GL #1101]

5258.	[func]		Added support for the GeoIP2 API from MaxMind. This
			will be compiled in by default if the "libmaxminddb"
			library is found at compile time, but can be
			suppressed using "configure --disable-geoip".

			Certain geoip ACL settings that were available with
			legacy GeoIP are not available when using GeoIP2.
			[GL #182]

5257.	[bug]		Some statistics data was not being displayed.
			Add shading to the zone tables. [GL #1030]

5256.	[bug]		Ensure that glue records are included in root
			priming responses if "minimal-responses" is not
			set to "yes". [GL #1092]

5255.	[bug]		Errors encountered while reloading inline-signing
			zones could be ignored, causing the zone content to
			be left in an incompletely updated state rather than
			reverted. [GL #1109]

5254.	[func]		Collect metrics to report to the statistics-channel
			DNSSEC signing operations (dnssec-sign) and refresh
			operations (dnssec-refresh) per zone and per keytag.
			[GL #513]

5253.	[port]		Support platforms that don't define ULLONG_MAX.
			[GL #1098]

5252.	[func]		Report if the last 'rndc reload/reconfig' failed in
			rndc status. [GL !2040]

5251.	[bug]		Statistics were broken in x86 Windows builds.
			[GL #1081]

5250.	[func]		The default size for RSA keys is now 2048 bits,
			for both ZSKs and KSKs. [GL #1097]

5249.	[bug]		Fix a possible underflow in recursion clients
			statistics when hitting recursive clients
			soft quota. [GL #1067]

	--- 9.15.1 released ---

5248.	[func]		To clarify the configuration of DNSSEC keys,
			the "managed-keys" and "trusted-keys" options
			have both been deprecated.  The new "dnssec-keys"
			statement can now be used for all trust anchors,
			with the keywords "iniital-key" or "static-key"
			to indicate whether the configured trust anchor
			should be used for initialization of RFC 5011 key
			management, or as a permanent trust anchor.

			The "static-key" keyword will generate a warning if
			used for the root zone.

			Configurations using "trusted-keys" or "managed-keys"
			will continue to work with no changes, but will
			generate warnings in the log. In a future release,
			these options will be marked obsolete. [GL #6]

5247.	[cleanup]	The 'cleaning-interval' option has been removed.
			[GL !1731]

5246.	[func]		Log TSIG if appropriate in 'sending notify to' message.
			[GL #1058]

5245.	[cleanup]	Reduce logging level for IXFR up-to-date poll
			responses. [GL #1009]

5244.	[security]	Fixed a race condition in dns_dispatch_getnext()
			that could cause an assertion failure if a
			significant number of incoming packets were
			rejected. (CVE-2019-6471) [GL #942]

5243.	[bug]		Fix a possible race between dispatcher and socket
			code in a high-load cold-cache resolver scenario.
			[GL #943]

5242.	[bug]		In relaxed qname minimization mode, fall back to
			normal resolution when encountering a lame
			delegation, and use _.domain/A queries rather
			than domain/NS. [GL #1055]

5241.	[bug]		Fix Ed448 private and public key ASN.1 prefix blobs.
			[GL #225]

			  or revoked.
			[GL #714]

5151.	[func]		Options that have been been marked as obsolete in
			named.conf for a very long time are now fatal
			configuration errors. [GL #358]

5150.	[cleanup]	Remove the ability to compile BIND with assertions
			disabled. [GL #735]

5149.	[func]		"rndc dumpdb" now prints a line above a stale RRset

			deleted when running dnssec-keymgr for the first
			time. [GL #117]

5139.	[bug]		If possible, don't use forwarders when priming.
