 +      Created the initial, bare-bones implementation of DHCP-DDNS service
 +      process class, D2Process, and the abstract class from which it derives,
 +      DProcessBase. D2Process will provide the DHCP-DDNS specific event loop
 +      and business logic.

+       b10-xfrin now has tighter control on the choice of IXFR or AXFR
+       through zones/request_ixfr configuration item.  It includes

+       now also uses AXFR whenever necessary, so it is now safe to try
+       IXFR by default and it's made the default.  The previous
+       use_ixfr configuration item was deprecated and triggers startup
+       failure if specified; configuration using use_ixfr should be
+       updated.
