ChangeLog

1386.	[func]		fdupont
	Extented 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

	(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)

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

	(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 upto MAX UINT32 in all subnet id columns. Exiting
	databases may be updated without data migration.
	(Trac #5416, #5522, git d1dd0f2e27ffa49515c17cf68d54f162359b6384)

1368.	[func]		tmark

	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)

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

1352.	[func]		fdupont

1348.	[build]		fdupont
	Modified configure.ac to include premium module m4 macros, if the
	module is present. Prior to this it relied on premium having it's
	own configure.ac script.
	(Trac #5400, git 38c4f2fb8fc8c8874a0e4671cc295a049acf675f)

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)

1343.	[func]		fdupont

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

	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
