+       Added access to the peer address, link address and option
+       information added by relays in a DHCPv6 message.
+       (Trac $4269, git tbd)
+ 
 +1101. [bug]           stephen
 +      Made DHCPSRV_MEMFILE_LFC_UNREGISTER_TIMER_FAILED a debug message as the
 +      condition leading to it (trying to unregister a timer that is not
 +      registered) does not have an adverse effect on the operation of Kea.
 +      (Trac #4293, git 06204c5d347d0df359af69974c155d0fa9725b44)

 +1100. [bug]           tmark
 +      Wrapped asio/asio.hpp with logic to suppress optimization when building
 +      under GCC 5.2.0 through 5.3.1 and BOOST_ERROR_CODE_HEADER only is defined.
 +      This avoids an issue in the asio socket layer that was incorrectly
 +      reporting socket read errors causing unit tests to fail and kea-dhcp-ddns
 +      to loop logger calls in the error handler (aka double errors).
 +      (Trac #4243, git 082f846f37cb32964c876b2bff5fcac82d1eaaf0)

 +1099. [func]          marcin
 +      Updated Host Manager API to allow for retrieving host reservations
 +      by any type of host identifier. Previously it was only possible
 +      to retrieve host reservations by hardware address or DUID.
 +      (Trac #4302, git 3979656c918164e3c39e0e8fb78b2862a2b5e95a)

  1098. [func]          kalmus, marcin
        Implemented IPv6 address/prefix reservations in MySQL.
