+<ul>
+<li>In the MobilityHelper class, the functions EnableAscii () and EnableAsciiAll () were changed to use output stream wrappers rather than standard C++ ostreams. The purpose of this change was make to make them behave analogously to other helpers in ns-3 that generate ascii traces.  Now, the file stream that is open in MobilityHelper is closed nicely upon asserts and program exits.</li>
