+<li><b>New TCP architecture</b>
+<p>TcpSocketImpl was replaced by a new base class TcpSocketBase and
+several subclasses implementing different congestion control.  From 
+a user-level API perspective, the main change is that a new attribute
+"SocketType" is available in TcpL4Protocol, to which a TypeIdValue
+of a specific Tcp variant can be passed.  In the same class, the attribute 
+"RttEstimatorFactory" was also renamed "RttEstimatorType" since it now
+takes a TypeIdValue instead of an ObjectFactoryValue.  In most cases, 
+however, no change to existing user programs should be needed.
