+New user-visible features
+-------------------------
 - A new random variable base class called 'RandomVariableStream', has been
-introduced.  This base class derives from ns3::Object, unlike the current 
-'RandomVariable' class which is a special type of object in the ns-3 
-system to date.  By making this class derive from ns3::Object, it can be 
-handled with the Ptr class, can carry attributes, and can have its parameters
-and initial state saved in the config-store subsystem.  A new attribute
-called "Stream" has been introduced for this class, to allow users to
-better control the assignment of underlying pseudo-random sequences to
-the RandomVariableStream objects (bug 101).
