ChangeLog

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
