	Kea no longer uses the .../var/kea directory, for instance pid
	files are now in .../var/run/kea.
	BEWARE this applies to the kea-dhcp6-serverid file so if the
	server will not find the file at its new location it will believe
	it is the first time it is being started and will generate a new
	server DUID.  If that happens, clients will keep trying to get to
	the old server and be confused.

	The configuration syntax has changed. The Logging scope that used
	to be shared between all servers has been deprecated. Each daemon
	is supposed to define its own loggers using 'loggers' array. The
	old configuration syntax is still accepted, but is considered
	deprecated.  Kea 1.6 will accept it, but that capability will be
	removed in the future. Please migrate your configuration to new
	syntax.

	Implemented the management API using a control socket for the
	DHCP DDNS (D2) server. D2 now supports the following commands:
	build-report, config-get, config-set, config-test, config-write,
	list-commands, shutdown and version-get. Also, extended Control
	Agent (CA) to support one additional command: config-set.

	kea-dhcp4 now ensures that the message type option (53) is
	the first option in outbound DHCPv4 packets.  This was done
	to accommodate non-compliant clients that require the option
	to be first.

1505.	[bug]		marcin
	Corrected an issue in the lease_cmds hooks library which caused
	errors while adding leases with high lease expiration time value
	to the database. Many thanks to Shawn Routhier from Infoblox for
	finding and reporting the issue.
	(Gitlab #337,!167, git 3fcdc28814310ac93b3903897e952b3b60cfa0bc)

	Unicode parser for JSON structures has been improved. It now
	handles escape sequences better.

	Corrected behavior of the DHCP servers with respect to the
	"reconnect-wait-time" parameter setting. This parameter is
	specified in milliseconds, but the servers used to interpret
	it as specified in seconds.

	All YANG modules now have a revision specified. When starting,
	kea-netconf daemon will now check if the required modules are
	installed and have a proper revision. This should help spotting
	issues when migrating from older YANG modules.
	(Gitlab #204,!121, git 9e772e1472e073ee85924cfc706cb57a5e70a0b1)

1496.	[doc]		marcin
	Updated Kea documentation to reference RFC 8415, which is the
	new DHCPv6 specification. It obsoletes a number of RFCs:
	RFC 3315 (previous DHCPv6 specification), RFC 3633, RFC 3736,
	RFC 4242, RFC 7083, RFC 7283 and RFC 7550. Kea documentation
	now refers to RFC 8415 where appropriate instead of obsoleted
	RFCs.

1491.	[build]		tomek
	coroutine.hpp from Boost 1.68 has been added the Kea source.
	It is used only if the Boost library provided by the system
	is very old and does not include that header. This effectively
	reverts the change done in Kea 1.4.0.
	(Gitlab #293,!45, git df0f507b8b750c8dff1f537cad5b5748b7841852)

	Bumped up libraries version numbers for Kea 1.5.0 beta2 release.
	Also, generated logger message files are now installed with Kea.
	(Gitlab #62,!144, git 7dc8d73a58504fd81a49b1c54651388d53d98d53)

1490.	[bug]		marcin
	Applied fixes in Cassandra Host Manager which prevents Kea
	crash during an attempt to delete non-existing reservation.
	In particular, this crash was observed as a result of sending
	reservation-del command over RESTful API.
	(Gitlab #27,!138, git 8666ed4754ffd27f3aa46a2cf3e4b161a1d877ee)

	For Kea 1.5.0-beta2, congestion handling has been enabled by

	We will finalize the default setting prior to releasing Kea 1.5.0.
	(Gitlab #276,!132, git fda1f985997412a58d3b4eee4a1ca0588d3f3beb)

	loggers was moved from the removed logging container to global
	config parameters.
	(Gitlab #204, !97, git 1de6c2987ec9067b7c1baa577c6dcd6ddd1b30fb)

1484.	[bug]		marcin
	Resolved issues with MySQL backend failing to insert a lease
	to the MariaDB database on OpenSUSE. This fix may also
	improve stability of the MySQL backend on other systems running
	MariaDB.
	(Gitlab #53,!125, git 038eddbc7b904289e4b74b5ef2406cb57f79a646)

1483.	[func]		tmark
	Use of congestion handling is now optional via the 'enable-queue'
	flag added to 'dhcp-queue-control'.  It is disabled by default.
	When disabled Kea's DHCPv4 and DHCPv6 servers will consume packets
	directly from interface sockets in the main thread (i.e. employs
	pre Kea 1.5 technique).
	(Gitlab #260, !120, git 9e304fae48d0d0658fd39a21aba9da528b4cc6f4)

	(Gitlab #204,!98, git a830adcefd9306969216d35c51306df3610278bb)

1480.	[func]		fdupont
	The unused configuration parameter "always-include-fqdn"
	was removed. Configurations using it will be rejected as
	it is no longer recognized.
	(Gitlab #182,!128, git cafeba167e7c64370dd39eca4551f61acd89d3da)

1479.	[build]		fdupont
	Support for sysrepo 0.7.6 (and libyang 0.16-r2) was added.
	Previous versions of sysrepo (and libyang) are still supported.
	(Gitlab #176, !107, git 4304a10b21708afb2a7599c77bc7508a600333cb)

Kea 1.5.0-beta1 released on Nov 9, 2018

1477.	[build]		marcin
	Bumped up libraries version numbers for Kea 1.5.0 beta release.
	(Gitlab #261,!119, git 54d63139048e7fe2dd0384b547ed6f8b96ff0e8f)

1476.	[func]		tmark
	Added initial implementation of congestion handling to kea-dhcp4
	and kea-dhcpt6. This adds a new top level element to the server
	configurations, "dhcp-queue-control".  Both servers will now
	read client packets from interface sockets in a separate thread
	queueing them for server level processing.  For Kea 1.5-Beta
	this feature is always on.
	(Gitlab #42, !103, git 09d5ffebc8f9bfab2ab99c384eec9c3a3c915f39)

1475.	[func]		sebschrader
	Add authoritative feature for DHCPv4 from ISC DHCP: requests from
	unknown clients are dropped (default/previous behavior) or
	answered with DHCPNAK (new behevior with new authoritative flag
	set to true for the subnet). Patch proposed by Sebastian Schrader.
	(Gitlab #66, !115, git 0fc1b767826f214475025d8631227970de368de5)

1472.	[bug]		marcin
	Timeout is now reported by the HTTP client when connecting to the server
	takes too long. This eliminates HTTP client hangs when firewall is
	misconfigured and causes connection to never be established. This issue
	was found during Kea High Availability testing.
	(Gitlab #26,!106, git 9724823f160af0ef5e8ccdf779087ff08a04457a)

	proposing a patch!
	(Gitlab #61, #138, !114, git 901cac7dc85ad8dacf631bf3a5c266eefeb3e6a1)

1470.	[func]		marcin
	Improved lease database synchronization mechanisms in High
	Availability hooks library. The new implementation uses
	lease4-get-page and lease6-get-page commands to fetch leases
	from the partner server. This prevents timeouts occurring
	during long synchronizations as well as decreases CPU and
	memory consumption on the HA enabled servers during lease
	database synchronization.
	(Gitlab #78,!85, git c54ea216463dcc6df693c96c4a5f82c0fbec2ff6)

	to modify client class configuration of the DHCP servers.
	(Gitlab #64,!41, git c1c1d0b71496d81b330a8c1eb95996bbf634ada0)

	Doxygen errors fixed.
	(Gitlab #180,!93, git d12fb04d71c3b2d0e84ebb2c957334454b5705c4)

1466.	[func]		fdupont
	Added random number generation in services provided by
	the crypto library (and ultimately by the crypto backend,
	i.e. Botan or OpenSSL).
	(Gitlab #29,!9, git 609ddc69613dc828b3d93673d61a2c259c3944aa)

	Exclude mysql_cb hooks library from the Kea 1.5.0 release. This
	library will be added back in Kea 1.6.0 release.
	(Gitlab #93,!105, git 49572aa300ea2b25712d7e8cea0dd0df34faf7ee)

1463.	[bug]		tmark
	Added missing parsing logic for the reservation-mode value,
	"global", to kea-dhcp6.  The parsing logic was somehow omitted
	and caused kea-dhcp6 configuration parsing to fail on values
	of "global".
	(Gitlab #129,!55, git 00352d701f61274f0993b468a413af6c5623af3d)

1462.	[build,doc]	tomek,sgoldlust,vicky
	Kea REST API is now documented. Thanks to Suzanne Goldlust for
	providing descriptions for great majority of commands and to
	Vicky Risk for review and corrections. Also, docgen, a new

	Added new sample configurations providing all parameters at
	the exception of host reservations for DHCPv4 and DHCPv6 servers

	Resolved multiple problems causing slow synchronization of

	synchronization timeout.

	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

	evaluated. Note these classes may be used to select a pool but

	to allocate a lease "after 0 attempts".

	DHCPv6 server supports shared networks. It allows for grouping
