 - (wifi) Support for MPDU aggregation has been added to the wifi model, 
   as well as a number of related example programs.
+- (wifi) Added two combined power and rate control mechanisms to the
+  wifi module.  The new mechanisms, PARF and APARF, are the first in the
+  wifi module to jointly control transmission power and data rate.  Two use 
+  case examples (PowerAdaptationDistance and PowerAdaptationInterference)

 - (wifi) PARF and APARF WiFi rate controls have been added to the wifi model.
