    - two options of handover algorithms for enabling automatic handover trigger
      in LTE simulation: A2-A4-RSRQ and strongest cell (A3-RSRP).
 
+- A new FixedRoomPositionAllocator has been adeded to the buildings
+  module. It allows to generate a random position uniformly
+  distributed in the volume of a chosen room inside a chosen building.  
+
+- A new attribute ns3::LteRlcAm::TxOpportunityForRetxAlwaysBigEnough
+  allows to overcome the lack for re-segmentation in the RLC AM
+  implementation by assuming that the size of a TxOpportunity is
+  always big enough for the RLC AM PDU to be retransmitted.
+
+- After some profiling, the code of LteMiErrorModel has been optimized
+  for speed, resulting in a significantly lower execution time of the
+  LTE model when used with the error model enabled.
