 *** Changes since GDB 7.1
 
+* C++ Improvements:
+
+  ** Argument Dependent Lookup (ADL)
+
+  In C++ ADL lookup directs function search to the namespaces of its
+  arguments even if the namespace has not been imported.
+  For example:
+    namespace A
+      { 
+        class B { }; 
+        void foo (B) { }
+      }
+    ...
+    A::B b
+    foo(b)
+  Here the compiler will search for `foo' in the namespace of 'b'
+  and find A::foo.  GDB now supports this.  This construct is commonly
+  used in the Standard Template Library for operators.
+
+  ** Improved User Defined Operator Support
+
+  In addition to member operators, GDB now supports lookup of operators
+  defined in a namespace and imported with a `using' directive, operators
+  defined in the global scope, operators imported implicitly from an
+  anonymous namespace, and the ADL operators mentioned in the previous
+  entry.
+  GDB now also supports proper overload resolution for all the previously
+  mentioned flavors of operators.

 * New features in the GDB remote stub, GDBserver
 
-  - GDBserver now support tracepoints.  The feature is currently
-    supported by the i386-linux and amd64-linux builds.
+  - GDBserver now support tracepoints (including fast tracepoints).
+    The feature is currently supported by the i386-linux and
+    amd64-linux builds.  See the "Tracepoints support in gdbserver"
+    section in the manual for more information.  GDBserver JIT
+    compiles the tracepoint's conditional agent expression bytecode
+    into native code whenever possible for low overhead dynamic
+    tracepoints conditionals.  For such tracepoints, an expression
+    that examines program state is evaluated when the tracepoint is
+    reached, in order to determine whether to capture trace data.  If
+    the condition is simple and false, processing the tracepoint
+    finishes very quickly and no data is gathered.
 
   - GDBserver now supports x86_64 Windows 64-bit debugging.
