C++ Language Changes in Clang
-----------------------------
+- Clang now correctly implements language linkage for functions and variables.
+ This means that, for example, it is now possible to overload static functions
+ declared in an ``extern "C"`` context. For backwards compatibility, an alias
+ with the unmangled name is still emitted if it is the only one and has the
+ ``used`` attribute.
