 ====================================
 
-* Special methods :meth:`complex.__complex__` and :meth:`bytes.__bytes__` are implemented to

+  the :class:`typing.SupportsComplex` and :class:`typing.SupportsBytes` protocols.

-* ``siphash13`` is added as a new internal hashing algorithms. It has similar security
-  properties as ``siphash24`` but it is slightly faster for long inputs. ``str``, ``bytes``,

-  hash-based pyc files now use ``siphash13``, too.
