1428.	[bug]		marcin
	Corrected behavior of the standby server in the HA hot-standby
	mode, which failed to monitor delays in responses to the
	DHCP queries sent to the primary server after the primary
	server became unavailable. This resulted in transition of
	the standby server to the partner-down state immediately
	after detecting interruption in communication with the
	primary over the control channel.

1427.	[bug]		marcin
	Resolved multiple problems causing slow synchronization of
	leases in the HA hooks library, including adjusting
	timeouts in control channel and improving performance of
	responses sent by the Command Manager to Control Agent.
	Also, introduced 'sync-timeout' configuration parameter
	into HA hooks library to control lease database
	synchronization timeout.

1426.	[func]		fdupont
	Added KNOWN and UNKNOWN built-in client classes: after host lookup
	if a matching host entry is found the incoming packet is added to
	the KNOWN class, if none is found to the UNKNOWN class. Then
	expressions depending directly or indirectly on these classes are
	evaluated. Note these classes may be used to select a pool but
	they may not to select a subnet.

	Corrected bug in the allocation engine which caused occasional
	lease allocation failures when a loaded hooks library set the
	callout status to non default value, e.g. "skip" rather than
	"continue". In such cases, the server reported that it failed
	to allocate a lease "after 0 attempts".

	kea-dhcp4 and kea-dhcp6 now validate the schema version
	of lease and host back ends after establishing a connection.
	If a schema version does not match the version the server
	expects, the server will emit an error log and close
	the connection. This applies to MySQL, PostgreSQL, and Cassandra.

	kea-dhcp4 parsing now treats renew-timer and rebind-timer
	as optional with no defaults. The logic for sending them
	to the client was changed to: send rebind-timer only
	when it is less than the lease lifetime; and send renew-timer
	only when it less than either the rebind-timer if specified,
	or lease lifetime in the absence of rebind-timer.

	(Trac #5625, git df3068ba0e520df4d96dd38e2de679beb99f2e23)

Kea 1.4.0-beta released on May 18, 2018

1404.	[doc]		tomek
	Hooks package installation intruction added to Kea
	User's Guide.
	(Trac #5427, git 7bc5e4297e8b2ccb87d5d5d79ae066fe32964841)

1403.	[build]		tomek
	Support for hook packages has been updated. The --with-tierX
	flags have been removed. Each hook library is now detected
	independently.
	(Trac #5619, git aa1f95d699dc664a5660db120ef71edee910a9b3)

1402.	[bug]		tomek
	Fixed a crash that was caused by hook library registering
	new hook points. This fixes unit-tests with forensic
	logging, but the problem was generic and could cause
	other libraries to segfault during unloading or reconfiguration.
	(Trac #5577, git 2f9d1aa95c16e12fabc50d581b966f20b6d8a950)

1401.	[bug]		tmark
	Corrected an issue which caused kea-dhcp4 and kea-dhcp6 servers
	to unload their hooks libraries upon receipt of the first client
	message following a dynamic reconfigure.
	(Trac #5564, git 5111f569bd251c2a98a2e6d958e8f6b640a1802d)

1400.   [func]		tmark
	A new hooks library, Stat Cmds, has been added to the open source
	distribution.  This library provides commands for fetching lease
	allocation statistics using lease backend as the source for
	lease counts per state.  This resolves an issue in deployments,
	where multiple Kea servers share a common lease backend, which made
	it difficult to obtain accurate lease statistics.
	(Trac #5589, git 36f20f1c8b28f629fe2896b817ac0f3c6026fe0e)

1399.	[func]		tmark
	Support for fetching lease allocation statistics by subnet-id
	or subnet-id range has been added to the Cassandra back end. This
	allows it to be used in conjunction with the Stat Cmds hooks
	library commands for fetching shared lease statistics.
	(Trac #5588, git 3fcfefdea5ac838936c2109ecbbbc32eabc8fdba)

1398.	[bug]		fdupont
	Fixed bug in configurations where "outbound-interface" parameter
	was set to "use-routing", which in some cases would reset outbound
	interface index to a negative value and cause the server to fail
	to respond to the clients.
	(Trac #5515, git 9d8d00f1f127ee606f09f7ff6006f0d142aac976)

1397.	[bug]		marcin
	A bug in http client library was fixed. The IPv6 address specified
	in brackets is now supported properly.
	(Trac #5620, git fe38c4368853e47bc993d6c3844cdddba5effde5)

1396.	[bug]		tmark
	The PostgreSQL schema was expanded to include two new tables:
	lease4-stat and lease6-stat and triggers to update them as leases
	are modified. This resolves an issue in deployments, where multiple
	Kea servers share a common PostgreSQL lease database, which made
	it difficult to obtain accurate lease statistics. Since these statistics
	are now tracked by the database, they do not have to be recalculated at
	startup or following reconfiguration. This may result in less
	processing overhead during these events. The new statistics will be
	accessible via a new Hooks library, being developed for Kea 1.4
	under #5589.
	(Trac #5587, git 36a0160de0df7789eea224954717be05c08638b7)

1395.	[bug]		tmark
	The MySQL schema was expanded to include two new tables:
	lease4-stat and lease6-stat and triggers to update them as leases
	are modified. This resolves an issue in deployments, where multiple
	Kea servers share a common MySQL lease database, which made it difficult
	to obtain accurate lease statistics. Since these statistics are now
	tracked by the database, they do not have to be recalculated at startup
	or following reconfiguration. This may result in less processing overhead
	during these events. The new statistics will be accessible via a new Hooks
	library, being developed for Kea 1.4 under #5589. 
	(Trac #5586, git a070c327668c10de3b28f5e249f91d6d16a97ff5)

1394.	[doc]		marcin
	Documented High Availability hook library in the Kea
	Administrator Reference Manual.
	(Trac #5478, git 3db34400d0331e3d4fc208529eeb18f6abfb6562)

1393.	[build]		marcin
	Install new header files introduced since Kea 1.3 release.
	Also, bumped up libraries version numbers for Kea 1.4 beta
	release.
	(Trac #5590, git 64351229a30832735c5a81ac17ca1521aa2483b2)

1392.	[func]		fdupont, marcin
	Implemented new hook point "leases6_committed" in the DHCPv6
	server. It supports new next step status NEXT_STEP_PARK
	which causes the server	to "park" the client's DHCP packet.
	(Trac #5458, git 04d6fb0a0ac5b9dff2a02764cc9265f9a2a05ae8)

1391.	[func]		tmark
	For both kea-dhcp4 and kea-dhcp6, the "ip-address" parameter
	in the "relay" element for both subnets and shared networks,
	has been replaced with a list form, "ip-addresses".  Configuration
	parsing will continue to honor the singular form, but it should
	be considered deprecated.  In addition, an omission in 1.3 that
	caused shared network parsing to ignore the "relay' element has
	been corrected.
	(Trac #5535, git f4601abdb657122a8ba5d7784eded773ec01d171)

1390.	[doc]		tomek
	User's Guide documentation for RADIUS and Host Cache written.
	(Trac #5538, git c73337a8ec691874b8ac0b2efcd8708f1a79acbb)

1389.	[func]		fdupont
	dhcp6_srv_configured hook point added.
	(Trac #5530, git 3bb521f6ec8b4e2a1e57ec84b17ee12b0ccf0f83)

1388.	[build]		tmark
	Modified configure script to support --with-dhcp-mysql and
	--with-dhcp-pgsql but emit a deprecation warning message
	encouraging their replacement with --with-mysql and --with-pgsql.
	(Trac #5567, git 53761069761ddde44636baa30185322debfe4186)

1387.	[func]		tmark
	perfdhcp no longer requires -r (rate) be specified in order to use
	-D<max-drop>, -n<num-request>, -p<test-period> and -t<report> options.
	(Trac #5115, git c3ba89c56882cac1080899ad201f0c02056eef38)

1386.	[func]		fdupont
	Extended comment / user-context support to DHCP-DDNS and
	Control Agent configuration syntax.
	(Trac #5495, git fe79959e3bc3c46ccb89661cb27696671a8508b8)

1385.	[func]		tomek
	lease4-wipe and lease6-wipe are now able to wipe all leases
	from all configured subnets if subnet-id specified is 0
	or the subnet-id parameter is omitted.
	(Trac #5543, git ecaf777dff4b8d1100c2a97c4fb1cf8f8e63566d)

1384.	[func]		fdupont
	Significant improvements to client classification introduced.
	The order of classes evaluation has changed from alphabetical
	to the order of appearance. New 'member' expression allows
	combination of classes. The new 'only-if-required' and
	'require-client-class' parameters controlling the scope of
	a class have been introduced.
	(Trac #5474, git 3f2d93f0731fc1858b20e831a7d1f090ea8841fe)

1383.	[func]		tmark
	kea-dhcp4 and kea-dhcp6 can now be configured to attempt to
	reconnect to MySQL backends if connectivity is lost.
	(Trac #5556, git b31da6f9a3545a2cac228eb17c59d72b6b4823f2)

1382.	[func]		fdupont
	Added support for generalized UDP Source Port for DHCP Relay
	(RFC 8357) for DHCPv4, DHCPv6 and DHCPv4-over-DHCPv6. Note
	this required changes to the inter-server protocol used by
	our 4o6 implementation, and is therefore not backward
	compatible.
	(Trac #5404, git 2a6049947ad4caaaa697dba8cb7669a09264f0bc)

1381.	[bug]		marcin
	Corrected a bug in the libkea-asiolink library which caused
	the DHCP servers to crash while processing commands over
	the unix domain socket on some systems.
	(Trac #5580, git cb5276a24436a9e9ce4d1ab4630e7193a4c2d803)

1380.	[func]		fdupont
	Implemented lease6-get-all command in lease_cmds hooks library.
	(Trac #5469, git a0bb7188df47a0f8020ff57739c5a6ab5f7e9828)

1379.	[func, bug]	marcin
	The network_state argument is provided to the callouts in
	the dhcp4_srv_configured hook point. Also, fixed a couple
	of minor bugs in the HTTP client classes.
	(Trac #5470, git 93e2b2198c3163afb81d51fdf5ec547602a12415)

1378.	[doc]		tomek
	New parameter subnets-action for network4-del and network6-del
	commands is now documented.
	(Trac #5441, git 8b2ffabb3d1ba709f319df2b34d0804ee824446b)

1377.	[doc]		tomek
	New parameters for Cassandra are now documented.
	(Trac #5484, git 56e7026ea2bfab99dbfa1a047dc920ec2f743540)

1376.	[func]		razvan
	Cassandra backend improvements: get all IPv4 leases, delete
	hosts, ability to store fixed DHCPv4 fields (next-server,
	server-hostname, boot-file-name) and user contexts in host
	reservations. Also, the ability to store MAC address details
        in DHCPv6 leases on PostgreSQL has been improved.
	(Github #70, git 8cd0c1ae416be88baf69c2243e83a429d6d5c965)

1375.	[func]		tmark
	When encountering errors unpacking vendor specific options,
	both kea-dhcp4 and kea-dhcp6 will now log the error, skip
	unpacking any remaining options, and then attempt to process
	the packet as is.  Prior to this the servers would log the issue
	and then drop the packet.
	(Trac #5551, git 59ef33ee17672c55cee4ec86ff59737b361a3c21)

1374.	[func]		tmark
	kea-dhp4 and kea-dhcp6 can now be configured to attempt to
	reconnect to Postgresql backends if connectivity is lost.
	(Trac #5477, git 8e62a058382b2245d418cfbf829776934c638e5e)

1373.	[func]		marcin
	Implemented leases parsing from JSON in libkea-dhcpsrv.
	(Trac #5466, git 84c2a2084b0fb7c086fc6b9502f7ff58b708174e)

1372.	[func]		marcin
	Implemented new hook points "dhcp4_srv_configured" and
	"leases4_committed" in the DHCPv4 server. The latter supports
	new next step status NEXT_STEP_PARK which causes the server
	to "park" the client's DHCP packet.
	(Trac #5457, git af43f07b0e227ccabcdf07a046a64cebb11bdccf)

1371.	[bug]		fdupont
	Fixed a bug in JSONfeed tool which did not correctly handle
	strings and interpret their content.
	(Trac #5513, git 231e923a85db7fb8305c7baa4d15f766fdf60942)

1370.	[bug]		tmark
	Fixed a bug which prevented inserting multiple host reservations
	where IPv4 address was unspecified or when selected subnet identifier
	was not specified (5416).  Corrected inconsistent data types for
	subnet id columns in both Postgres and MySQL schemas.  Now both
	schemas support up to MAX UINT32 in all subnet id columns. Exiting
	databases may be updated without data migration.
	(Trac #5416, #5522, git d1dd0f2e27ffa49515c17cf68d54f162359b6384)

1369.	[bug]		marcin
	Multiple critical performance optimizations in the allocation
	engine for shared networks.
	(Trac #5437, git 9d8bcd39802795d48c737a05ef3de3634a28ca4e)

1368.	[func]		tmark
	kea-dhcp4 now explicitly logs packets dropped due to a lack
	message type as a log type DHCP4_PACKET_DROP_0009.  Prior
	to this such packets were logged has having an unsupported
	message type of 0.
	(Trac #5553, git ff97e5ffb5f3478be71aae8130b6eff3208bd69a)

1367.	[func]		fdupont
	Added initial skeleton implementation for Radius hook library.
	(Trac #5524, git 832aa23b89eab71875bcbdb1e955eb92fdc0e01a)

1366.	[func]		fdupont
	Implemented FNV hashing function. Cassandra backend no longer
	explicitly depends on OpenSSL.
	(Trac #5502, git 71de75c3bb099f21fdef0d41806da281d6271287)

1365.	[func]		fdupont
	Both DHCPv4 and DHCPv6 servers can now listen on loopback
	interfaces. This capability requires setting socket type to UDP in
	DHCPv4. Note the feature has not been thoroughly tested.
	(Trac #5390, git f38cbd73581a7a0f8634a63cb17f9b60407e3acc)

1364.	[func]		fdupont

1362.	[func]		razvan, andrei
	A new parameter exit-wait-time has been added to perfdhcp. It is
	now possible to tell perfdhcp to wait certain amount of time after
	exit conditions are met before actually terminating.
	(Github #55, git 0cd1178ae092fa0c2f122d0e16fb673b4074a6e6)

1361.	[func]		razvan, andrei, tomek
	Support for Google Benchmark has been added. To compile
	benchmarking support, please use --with-benchmark option.
	(Github #36, git d6819971410b460d7742c762844e2e75ba580944)

1360.	[build,bug]	fdupont
	Cassandra build fixes for macOS.
	(Trac #5494, git cb0d735628aefd6bca2acc11b73d1f66b45d1c40)

1359.	[bug]		rcgoodfellow
	Fixed bug in kea-admin causing error on lease-dump.
	(Github #61, git 2c9454ec56edc8f3cff8a23329f53ced0d172280)

1358.	[func]		andreipavelQ,tomek
	The logging configuration is now applied early, which helps
	seeing errors in case the new configuration is faulty.
	(Github #41, git d77fbec5a003a69cab207aa741133015f2657878)

1357.	[build]		andreipavelQ
	--with-dhcp-mysql renamed to --with-mysql and
	--with-dhcp-pgsql renamed to --with-pgsql. These names were
	leftovers from old BIND10 times when Kea was part of bigger
	solution that also provided DNS services. Kea is now a stand-alone
	software, thus the -dhcp- doesn't make sense in those options any
	more.
	(Github #40, git 318c9e3d3db9bb938ced27932d8401172529a2ff)

1356.	[doc]		andreipavelQ
	Documentation has been upgraded to DocBook 5.0.
	(Github #39, git 9b6705bd6c534128ec18820ff0cbdd72b7fce9e9)

1355.	[func]		tomek
	Lightweight 4over6 options reinstantiated. Definitions for DHCPv6
	options 89 through 96 were added back. DHCPv4 v4 Parameters Option
        159 has its definition tweaked slightly.
	(Trac #5514, git 6a4aac2b3bfffe41460db6d1cd3c55b1430aa50c)

1354.	[build]		andrei
	Support for coverage tests has been improved.

1352.	[func]		fdupont
	It is now possible to specify client classification restrictions
	on per pool basis. This capability will be useful for grouping
	certain types of devices into specific address and/or prefix
	pools.

1344.	[func]		andrei, razvan
	Support for host reservations stored in Cassandra added. The core
	functionality was added. There are some limitations (delete,
	client classes, fixed DHCPv4 fields, statistics recount, etc.)
	These will be addressed in upcoming tickets.
	(github #37, git e37606fd2d0c02234a55f7445c52a12b2e7a82ec)
