+Features added
+--------------
+
+* Added support for Python binary operator semantics.
+  One can now define, e.g. both ``__add__`` and ``__radd__`` for cdef classes
+  as for standard Python classes rather than a single ``__add__`` method where
+  self can be either the first or second argument.  This behavior is guarded
+  by the ``c_api_binop_methods`` directive.
+  (Github issue #2056)
