ChangeLog

1525.	[func]		fdupont
	Defined API for the DHCPv6 Configuration Backend.
	(Gitlab #458,!231, git f16e03d9bf1c10903c16b2614223b10880f73d50)

1524.	[func]		tomek
	Support for vendor options improved in DHCPv4 and DHCPv6. Kea is now
	able to send back vendor suboptions, even if the client packet didn't
	include DHCPv4 vivso (125) or DHCPv6 vendor (17) option. Usage of client
	classification in such a case is required, though.
	(Gitlab #464,!238, git 5c79da9358862657a631a9a8fc2ce79ae26b762e)

1523.	[bug]		fdupont
	IfaceMgr::send method now returns proper status that matches
	its documentation. Thanks to Matthias Stoeckl from Secunet
	for reporting this issue.
	(Gitlab #417,!221, git 4be58523f38097cea81ea06161aead58e00aeb2a)

1522.	[bug]		marcin
	The "unspecified" DHCP timer values (e.g. renew-timer) are
	represented as NULL values in the database. This corrects
	a bug whereby the unspecified timers defaulted to 0 which
	prevented the DHCP server from calculating the timers to
	be sent to the client. Instead a value of 0 was sent.
	(Gitlab #451,!227, git 5ec9a55528fbcfff4e0c808f9a745b9fd3a5dfae)

1521.	[func]		marcin
	Removed subsecond precision for the timestamps in MySQL config
	backend. It caused issues on systems with MySQL version prior
	to 5.6.4 which don't support subsecond timestamp values.
	(Gitlab #444,!229, git 71200e98f5a862908240a0d2e269b5da23290af9)

1520.	[build]		fdupont
	Made perfdhcp build optional and off by default: to build it
	please use the new --enable-perfdhcp configure flag.
	(Gitlab #340,!220, git b2d9a5559c348e82d6730809ccf1429097a9872c)

1519.	[bug]		Brent Bloxam
	A bug in kea-admin that always assumed the PostgreSQL database is
	always local has been fixed. Thank you to Brent Bloxam from
	Beanfield Metroconnect for submiting a patch!
	(Gitlab #423,!216, git d14e2f34c7d544aeb5e1e219f305fac9ab18c498)

1518.	[func]		marcin
	Extended MySQL schema to include the types of the global DHCP
	parameters in the database. The Kea servers will use this
	information to cast the values fetched from the database into
	their actual types. The supported types are: string, integer,
	boolean and real.
	(Gitlab #429,!217, git edd745c507ce5a888461df1489311de0c22cd312)

1517.	[func]		tmark
	kea-dhcp4 will now connect to and fetch configuration data from
	configured backends. At this point, only fetched subnet data is
	merged and used.
	(Gitlab #101,!202, git c572f8aea94349ff5fb4afee13a88ba811cc6459)

1516.	[func]		marcin
	Implemented audit trail for MySQL Configuration Backend. It allows
	for tracking incremental changes in the servers' configurations.
	Both mysql_cb hooks library and the MySQL schema have been updated
	to facilitate this feature.
	(Gitlab #396,!205, git 6d40db07ef641eef29405c42e718979e7a1e8675)

1515.	[func]		fdupont
	Changes required for new host commands that retrieve all host
	reservations from a given subnet (reservation-get-all,
	reservation-get-page) added. Also added documentation.
	(Gitlab #313,!199, git 991b2fadcb9e8171a78e27f95e4bfba6393d7824)

1514.	[func]		fdupont
	Control Agent and DHCP-DDNS daemons now support config-reload
	command, that instruct a given server to load again its
	configuration from a file on disk.
	(Gitlab #375,!192, git 93648a3a4918225e2c4413ae220fccc59eaea99a)

1513.	[func]		godfryd
	Fixed perfdhcp that now it keeps requested rate during performance
	testing. Previously it was always about 20% lower than expected.
	(Gitlab #283,!135, git 329f54bb151ec35888e9a8070cc5fa368d6f1f5e)

1512.   [func]      tmark
	kea-dhcp4 will now ignore empty Host Name (option code 12) values
	received from clients.  While an empty value for this option is
	not RFC-compliant, some clients do send them.  Prior to the this
	server would drop the entire packet.  In the spirit of being liberal
	in what we accept, the server will now simply omit the option.
	(Gitlab #40,!203, git f41bd35c3e7a3bdc1f31c5602fd91d5c84c60163)

1511.	[func]		fdupont
	Obsolete experimental secure DHCPv6 options (701-704) removed.
	(Gitlab #386,!196, git 1114527652615fb730e323946cafaf1c7ca72b42)
