 * Replaced all numeric ``BINARY_*`` and ``INPLACE_*`` instructions with a single
   :opcode:`BINARY_OP` implementation.
 
-* Added a new :opcode:`CALL_METHOD_KW` opcode.  Calls a method in a similar
-  fashion as :opcode:`CALL_METHOD`, but also supports keyword arguments.  Works
-  in tandem with :opcode:`LOAD_METHOD`.
+* Replaced the three call instructions: :opcode:`CALL_FUNCTION`,
+  :opcode:`CALL_FUNCTION_KW` and :opcode:`CALL_METHOD` with
+  :opcode:`CALL_NO_KW`, :opcode:`CALL_KW` and :opcode:`PRECALL_METHOD`.
+  This decouples the argument shifting for methods from the handling of
+  keyword arguments and allows better specialization of calls.
 
 * Removed ``COPY_DICT_WITHOUT_KEYS``.
