<li><b>Ipv4::IsDestinationAddress (Ipv4Address address, uint32_t iif)</b> Method added to support checks of whether a destination address should be accepted
as one of the host's own addresses. RFC 1122 Strong/Weak end system behavior can be changed with a new attribute (WeakEsModel) in class Ipv4. </li>
+<li><b>Net-anim interface</b>: Provides an inteface to net-anim, a network animator for point-to-point
+links in ns-3. The interface generates a custom trace file for use with the NetAnim program.

+<li><b>Topology Helpers</b>: Previously, topology helpers such as a point-to-point star existed in the
+PointToPointHelper class in the form of a method (ex: PointToPointHelper::InstallStar). These topology
+helpers have been pulled out of the specific helper classes and created as separate classes. Several
+different topology helper classes now exist including PointToPointStarHelper, PointToPointGridHelper,
+PointToPointDumbbellHelper, and CsmaStarHelper. For example, a user wishes to create a
+point-to-point star network:<br>
