ChangeLog

1423.	[bug]		tmark
	kea-dhcp4 and kea-dhcp6 now retain and emit global, scalar
	parameters specified in their configuration.
	(Trac #5378, git 4d05122f03d00b10a888c768fe1725cae9d6aea6)

1422.	[build]		fdupont
	Commented out BOOST_ASIO_DISABLE_THREADS in configure to reflect
	the current use of threads by boost ASIO in Kea.
	(Trac #5615, git f3fc8b1a4257a42a97aaf88a36287bbe33d1f65b)

1421.	[build]		marcin
	Moved libdhcp_ha (High Availability) hooks library from
	premium to main Kea repository and changed its license to
	MPLv2.0. Future ChangeLog entries for this library will be
	tracked in the Kea ChangeLog file.
	(Trac #5645, git 19b2553d4869bdd52b63b6f7969052d8a724f78d)

1420.	[doc]		marcin
	Updated list of loggers in the Kea Administrator's Manual.
	The updated list contains all loggers, including those
	from supported hooks libraries.
	(Trac #5622, git bd94afc0af7183452c94f3b5768c6138f79d3b60)

1419.	[doc]		marcin
	Documented "sync-leases" configuration parameter of the HA
	hooks library in the Kea Administrator's Manual.
	(Trac #5621, git 4ebac3a411aa02d1cc3d74e7eaf3212ad208159a)

1418.	[bug]		marcin
	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".
	(Trac #5638, git f2e9b686ae52e1b06f660e1b522588b1440e2620)

1417.	[bug]		marcin
	Improved logging in the HTTP library both for the server and
	the client.
	(Trac #5205, git fd0bec610c89084d5a5d43ef032c9875c3e6ad46)

1416.	[bug]		fdupont
	Added support of recent Botan 2.x crypto backend.
	Note that Botan 1.[9-11] is still supported but not recommended.
	(Trac #5382, git 22651b1935a2397edfbddb9b8873c353c090f18e)

1415.	[bug]		tmark
	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.
	(Trac #5629, git 15c34afdba45be609e35284a209ad18ed66605f8)

1414.	[bug]		tmark
	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 #5596, git 38426e16ec04a786e35a65d27cbcb7dbabfe79b5)

1413.	[func]		fdupont
	Removed getAll, get4 and get6 methods using both hardware address
	and DUID from host backend (aka host data source) APIs.
	This is an *incompatible* change.
	(Trac #5563, git db4c34b069f114f93d9f29cdeb02b536a0fbc982)

1412.	[func]*		marcin
	The client classes used by the High Availability hook library
	use upper case "HA_" prefix and they are now built-in classes.
	This means that those classes do not need to be	declared in the
	server configuration.
	(Trac #5632, git 2d590bfd7d1b0eca377eb99eef83a3083a1d7399)

1411.	[bug]		fdupont
	Fixed warnings about lambda's not using captured variables.
	(Trac #5591, git f88a505823d39faec7dc5f647f40e6454e5dfc74)

1410.	[bug]		marcin
	Fixed multiple hanging Control Agent unittests.
	(Trac #5576, git 310af68101cba74220652ec2b403520fc5666dc0)

1409.	[doc]		marcin
	Documented in the User's Guide how Kea HA service behaves
	when the clock skew between active servers becomes too
	high.
	(Trac #5603, git ffaff4d2a03600bb4f81d335b49a840e31d03c8c)

1408.	[func]		tomek
	perfdhcp now supports -o option that adds DHCP options.
	This may be used to simulate various clients.
	(github #77, git b81dedb7f0a2516130e7bd799d9084c63f0e844c)

1407.	[bug]		tmark
	Corrected an issue where the destruction of loggers
	prior to the destruction of the TimerMgr singleton
	caused unit tests to segfault.
	(Trac #5626, git 9f4e3f9cd8acf8e7d1d3e714d8f904754377c00f)

1406.	[func]		fdupont
	Added pkg-config alternative to configure --with-cql path so
	now you can use either pkg-config or cql_config.
	(Trac #5488, git 55498ca3455517132533a39002ebfc05d26c7e38)

1405.	[bug]		tmark
	Corrected missing "override" warning in cql_lease_mgr.h
