+       The internal represenation of an "unused" subnet-id has been
+       changed from zero to 0xFFFFFFFF. The largest, valid value for
+       a subnet's ID is now 0xFFFFFFFE.  Three new constants have been
+       added so subnet_id.h:
+
+               isc::dhcp::SUBNET_ID_GLOBAL
+               isc::dhcp::SUBNET_ID_UNUSED
+               isc::dhcp::SUBNET_ID_MAX
+
+       which should be used in code/hooks in place of hard-coded values.
+       (Trac #5704, git 90fe9ca2cd6f63bcc7168bdc3786677db57b65ec)
