1316.	[bug]		marcin
	Corrected a bug which caused a returning DHCPv4 client performing
	4-way exchange to be assigned a different address from a shared
	network than previously allocated.
	(Trac #5388, git 601a387ba43d990947ee2e1a05e78851d8133a3c)

1315.	[bug]		marcin
	Created unit test for the case when there are several IPv6 subnets
	within a shared network and each subnet specifies the same
	DHCP option with a different value. This test verifies the fix
	applied with ticket #5364 which address the problem of assigning

	or config-write commands.
	(Trac #5267, git f2290503ed899f00c7f2f2b905b90bc360617340)

1312.	[func]		marcin, tomek
	Added new configuration parameter "outbound-interface", which
	controls how the outbound interface and source address is
	determined for the responses sent by DHCPv4 servers to relayed
	clients. The default setting is to use the same interface as
	the one over which the query has been received. The alternative
	is to use system routing to determine the right interface and
	source address.
	(Trac #5377, git d08088923ec1ea0d1cb8a947bd520174d874d25e)

1311.	[build]		fdupont

	(Trac #5210, #5339, #5352,
	git e531cda4e10114a8f14bcbf3d7e25b6584230875)

1310.	[bug]		marcin
	Documented "ia_pd" parameter for lease6_renew and lease6_rebind
	hook points.
	(Trac #5368, git 6842036714f84bf12529e1a43e12ac5a07e2e5c0)

1308.	[func]		fdupont
	Support for conditional token ifelse(condition, iftrue, iffalse)
	was added. It can be used in flex-id, client classification and
	possibly other expressions that may appear in the future.
	(Trac #5363, git 34c364abd23a1a745da79c10c69b94b8defad08b)

1307.	[func]		fdupont
	When an option is defined with a record type and the array
	flag is true the last record field is an array. All standard
	options supported by ISC DHCP and using this are now supported
	by Kea (so now there is no standard option supported only by
	ISC DHCP).
	(Trac #5226, git f66951dbda8f62122187ac3a99f0fdcc65b383d8)

1306.	[bug]*		marcin
	Respective Kea daemons now use their own default configuration
	files: kea-dhcp4.conf, kea-dhcp6.conf, kea-dhcp-ddns.conf and
	kea-ctrl-agent.conf. This change is aimed at eliminating the
	issue whereby 'config-write' command overrides configuration
	of all servers rather than just a configuration of the deamon
	to which this command has been sent.
	(Trac #5338, git 252e5e8a75fa42271b0cdb6edad3c152bbf3c515)

1305.	[bug]	tmark
	Corrected logic that was causing kea-dhcp4 to remove DNS entries
	when renewing leases with generated FQDN names.  Prior to this
	the server was incorrectly scheduling DNS removal when configured
	to generate the client's FQDN.
	(Trac #5369, git 18f57f502f1b9fb5bf7ef5ab995ddda60006fd39)

Kea 1.3.0-beta released on September 29, 2017

1304.	[bug,func]	fdupont
	The DHCPv4 Vendor Specific Information (code 43) option and
	private options (codes 224-254) can be redefined at the global
	scope or inside a client-class. This allows to support different
	definitions following the DHCPv4 Vendor Class Identifier (code 60)
	option or when defined as a binary option to accept with problems
	option 43 carrying a raw value.
	(Trac #5073, git b290b3cbaa926d4e9613f6607c5fcbae2301b266)

1303.	[func]		tmark
	The command handlers in the lease_cmds hook library are now
	implemented has hook callouts and registered with the Hooks
	manager. Prior to this they were registered as command handlers
	with the Command Mgr.
	(Trac #5332, git c902bda9f026720f6efbf2e5ad407302aeb5e466)

1302.	[func]		marcin, tomek
	DHCPv6 server supports shared networks. It allows for grouping
	multiple subnets and use them interchangeably to allocate
	IP addresses and other resources to a client located on the
	particular link. This mechanism is useful to extend an
	address space for the client belonging to a particular
	subnet and/or to segregate clients being on the same link but
	belonging to different classes, e.g. cable modem vs router.
	(Trac #5307, git 110d0c9e403af28e6810141f978d9bf55c381f14)

1301.	[func]		fdupont
	Added some standard option definitions which are supported
	by ISC DHCP but not (yet) by Kea.

1297.	[func]		tmark
	Added a hook point, "command-processed", to kea-dhcp4
	and kea-dhcp6 servers. This hook point occurs after
	a control channel command has been received and
	processed.
	(Trac #5111, git 043d17b0688d4ab25b12469d27859983cb297d07)

1296.	[bug]		tmark
	Altered the mysql backend logic to disable auto_reconnect and
	set session value of wait_timeout to a very large values. This
	avoids a segfault in MySQL client library caused by auto-reconnects
	occurring when kea server's MySQL connection is idle for longer
	than the global MySQL wait_timeout.
	(Trac #5354, git 9881ef6d772f27de82c048e198ba0ff9e71b9351)

	A basic shared networks examples added.
	(Trac #5357, git 74b824cc80f8be66084308c0bf12c1a71f311915)

1294.	[func]		marcin
	Implemented data structures holding configuration of shared
	networks. The new structures are unused until remaining tickets
	for shared networks implementation are completed.
	(Trac #5305, git 76dd46f7070c141cc89d772d69a897b67bd179a1)

	emitted.
	(Trac #5345, git 779040fa399fb2da271569dc315294463e28f852)

1292.	[func]		tomek
	User contexts are now supported for subnets. This adds a new
	functionality, but also makes the existing documentation example
	correct.
	(Trac #5350, git 828ecb6dbdaaedd97d2af79dfa9b7f4845d3a049)

1291.	[func]		fdupont

	retrieving server hostname and boot file name fields from
	the host reservation database. Many thanks to Juan Settecase
	for his assistance in identifying this issue.
	(Trac #5340, git 2fdc7efcb862ced3c1054620bf14e75a0db6aed2)

1289.	[bug]		marcin, tmark

	UnixDomainSocket. This was causing intermittent command
	channel write errors in kea-ctrl-agent on some Debian systems.
	(Trac #5336, git db251cb66ad77ba28ab44281323ddeb23cf29506)

1288.	[func]		marcin
	Documented subnet_cmds library in the Kea User's Guide.  Also moved
	several classes from dhcp<4/6> into lib/dhcpsrv to facilitate subnet
	command parsing.
	(Trac #5315, git d259f330a1690b20eb368f6252f5da2cdb6187de)

1287.	[bug]		tmark
	Logger configuration now correctly uses maxsize and maxver
	parameters, allowing log rotation to function properly.  Prior to
	this these values were not being propagated downward, causing log
	rotation to always be disabled.  The defaults for maxsize and
	maxver are 10Mb and 1 respectively.

	lease4-del, lease6-del, lease4-update, lease6-update,
	lease4-wipe and lease6-wipe that allow deleting and updating
	leases and also wipe all leases from a specific subnet.
	(Trac #5280, #5281, 94ff2448c8cf6e3321f4d1b3666a2e2b736f6c50)

	The configure script now configures the build to require the Boost
	system library (boost_system) by default.  The library must be
	installed and you may need to specify "--with-boost-lib-dir=<path>".
	Prior to this the default was to attempt to build Boost with headers
	only.  Building with headers only may still be done, though it is
	strongly discouraged, by specifying "--enable-boost-headers-only".
