 - Update to version 1.5.0
+  * Support for YANG/NETCONF, the ability to store major

+    using NETCONF.

+    reservation had to be associated with a specific subnet)
+  * Class commands – a new hook that allows dynamic changes
+    to be made to client classes without restarting.
+  * Performance and resiliency improvements to the High
+    Availability hook.
+  * A new congestion control feature to mitigate the effects of
+    heavy DHCP traffic conditions.
