	(Iface objects) are now non-copyable. As a result, the API
	of the Interface Manager functions returning the pointers
	to the Iface objects has changed.
	(Trac #3715, git 7415c74e38e13385a75e7200cb23b7d6ca86df7f)

910.	[func]		marcin

907.	[doc]		tmark
	Corrected depictions of kea-admin command line options for
	database-name in Kea Administrator Reference. Prior to this

904.	[bug]		marcin
	FreeBSD-only change: Disabled unit test expecting the death
	of the process when conditional variable was destroyed when

890.	[func]		marcin
	It is now possible to specify whether the DHCPv4 server
	should use raw sockets or IP/UDP datagram sockets to
	receive and send DHCP messages. The configuration format

	configuration files using an old format are incompatible
	with the latest version of Kea.

	DHCPv6 server avoids collisions between prefixes that are allocated
	as a result of receiving hints from the clients. Previously the
	whole prefix (including bits beyond the prefix length) was used to

	b10-dhcp-ddns now treats a DNS server response code of
	NXRRSET as a successful outcome when processing a request

	DNS data when the DNS server's response was NXRRSET.

766.	[func]		muks
	--disable-dns and --disable-dhcp configure arguments have been
	added to conditionally disable the DNS or DHCP components
	respectively. This facility can be used to do a DNS or DHCP-only
	build of BIND 10. DNS and DHCP components are both enabled by
	default.

	b10-dhcp-ddns may now be configured to disable DNS updates in
	in a given direction by simply not defining any domains for that

	a request was received that could not be matched to servers in a
	given direction it was failed immediately.

	b10-dhcp4, b10-dhcp6: IP address of the relay agent can now be

	and cable networks.

	b10-dhcp6: server parses DHCPv6 Vendor Class option. Previously
	the server failed to parse Vendor Class option having empty opaque

	DHCPv6 Vendor Class option and DHCPv4 V-I Vendor Class option is

	b10-dhcp6: Refactored the code which is processing Client FQDN
	option.  The major user-visible change is that server generates
	DDNS NameChangeRequest for the first IPv6 address (instead of all)
