+<h2>Changed behavior:</h2>
+<ul>
+  <li> For the TapBridge device, in UseLocal mode there is a MAC learning function. TapBridge has been waiting for the first packet received from tap interface to set the address of the bridged device to the source address of the first packet. This has caused problems with WiFi.  The new behavior is that after connection to the tap interface, ns-3 learns the MAC address of that interface with a system call and immediately sets the address of the bridged device to the learned one.  See <a href="https://www.nsnam.org/bugzilla/show_bug.cgi?id=1777">bug 1777</a> for more details.</li>
+  <li> TapBridge device now correctly implements IsLinkUp() method.</li>

+<h1>Changes from ns-3.18 to ns-3.18.1</h1>
+<h2>New API:</h2>
+<ul>
+  <li> It is now possible to randomize the time of the first beacon from an
+  access point.  Use an attribute "EnableBeaconJitter" to enable/disable
+  this feature.
+  </li>
+  <li> A new FixedRoomPositionAllocator helper class is available; it
+  allows one to generate a random position uniformly distributed in the
+  volume of a chosen room inside a chosen building.

+<h2>Changes to existing API:</h2>
+<ul>
+  <li> Logging wildcards:  allow "***" as synonym for "*=**" to turn on all logging.
+  </li>
+  <li> The log component list ("NS_LOG=print-list") is now printed alphabetically.
+  </li>
+  <li> Some deprecated IEEE 802.11p code has been removed from the wifi module
+  </li>

-  <li></li>
+  <li> The Python API scanning system (./waf --apiscan) has been fixed (bug 1622)

 <h2>Changed behavior:</h2>
 <ul>
-  <li></li>
+  <li> Wifi simulations have additional jitter on AP beaconing (see above) and some bug fixes have been applied to wifi module (see RELEASE_NOTES)
