0d8c3d6eed - A bug was fixed that could cause the DHCPv6 server to advertise/assign a 
previously allocated (active) lease to a client that has changed subnets,
  despite being on different shared networks.  Dynamic prefixes specifically
  allocated in shared networks also now are not offered if the client has
  moved.  [ISC-Bugs #21152]

c900c5b249 - The 'hardware [ethernet|etc] ...;' parameter in host records has been 
extended to attempt to match DHCPv6 clients by the last octets of a
  DUID-LL or DUID-LLT provided by the client.  [ISC-Bugs #19599]

2267da8477 - Both host and subnet6 configuration groups are now included whether a 
fixed-address6 (DHCPv6) is in use or not.  Host scoped configuration takes
  precedence.  This fixes two bugs, one where host scoped configuration
  would not be included from a non-fixed-address6 host record, and the equal
  and opposite bug where subnet6 scoped configuration would not be used when
  over-riding vlaues were not present in a matching fixed-address6 host
  configuration.  [ISC-Bugs #20069]

1aa0fe5e3e - A bug was fixed that caused the server not to answer some valid Solicit 
and Request packets, if the dynamic range covering any requested addresses
  had been deleted from configuration.  [ISC-Bugs #19134]

7d6180be3e - A bug in subnet6 parsing where options contained in subnet6 clauses would 
not be applied to clients addressed within that network was repaired.

- When configuring a "subnet {}" or "subnet6 {}" without an explicit
  shared-network enclosing it, the DHCP software would synthesize a
  shared-network to contain the subnet.  However, all configuration
  parameters within the subnet more intuitively belong "to any client
  on that interface", or rather the synthesized shared-network.  So,
  when a shared-network is synthesized, it is used to contain the
  configuration present inside the subnet {} clause.  This means that
  the configuration will be valid for all clients on that network, not
  just those addressed out of the stated subnet.  If you intended the
  opposite, the workaround is to explicitly configure an empty
  shared-network.

- A bug was fixed where Information-Request processing was not sourcing
  configured option values.

- A warning was added since the DHCPv6 processing software does not yet
  support class statements.

9ac4206a63 - DHCPv6 vendor-class options (VSIO) are now only sent when they appear 
on the DHCPv6 ORO.  This resolves a bug where VSIO options were placed
  in IA_NA encapsulated options fields.  [ISC-Bugs #17852]

b024480eba - The server now limits clients that request multiple addresses to one

7285af3087 - DDNS updates state information are now stored in 'binding scopes' that 
follow the leases through their lifecycles.  This enables DDNS teardowns
  on leases that are assigned and expired inbetween a server restart (the
  state is recovered from dhcpd.leases).  Arbitrary user-specified binding
  scopes ('set var = "value";') are not yet supported.

8eab95f2ee - DHCPv6 server Confirm message processing has been enhanced - it no

  as directed in RFC3315 section 18.2.2 - that is, to all clients
  regardless of the existence of bindings. [ISC-Bugs #17183]
