========================

* Replaced most ``BINARY_*`` instructions with a single :opcode:`BINARY_OP`
implementation.

* Replaced most ``INPLACE_*`` instructions with a single :opcode:`INPLACE_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`.
