 Revision 4.2.4
 --------------
 
+- SNMPv3 native Notification Originator examples extended to cover
+  many use cases.
 - The missing functionality of NOTIFICATION-TYPE objects being looked up
   at local Management Instrumentation and attached to TRAP/IMFORM message
   by Notification Originator is now fully implemented.
