+* Completion improvements
+
+  ** GDB can now complete function parameters in linespecs and
+     explicit locations without quoting.  When setting breakpoints,
+     quoting around functions names to help with TAB-completion is
+     generally no longer necessary.  For example, this now completes
+     correctly:
+
+      (gdb) b function(in[TAB]
+      (gdb) b function(int)
+
+     Related, GDB is no longer confused with completing functions in
+     C++ anonymous namespaces:
+
+      (gdb) b (anon[TAB]
+      (gdb) b (anonymous namespace)::[TAB][TAB]
+      (anonymous namespace)::a_function()
+      (anonymous namespace)::b_function()
+
+  ** GDB now has much improved linespec and explicit locations TAB
+     completion support, that better understands what you're
+     completing and offers better suggestions.  For example, GDB no
+     longer offers data symbols as possible completions when you're
+     setting a breakpoint.
+
+  ** GDB now TAB-completes label symbol names.
+
+  ** The "complete" command now mimics TAB completion accurately.
