+Changes for ``weakref.WeakKeyDictionary.update()``:
+
+* Removed code for updating ``WeakKeyDictionary`` objects by keyword arguments. This did not work correctly because weak references to ``str`` objects are not supported;
+* Added clear exception that keyword arguments are not supported in ``update()`` method;
+* Added test case.
