@ -481,6 +481,12 @@ New function :func:`abc.get_cache_token` can be used to know when to invalidate
caches that are affected by changes in the object graph. (Contributed
by Łukasz Langa in :issue:`16832`.)
New class :class:`~abc.ABC` has :class:`~abc.ABCMeta` as its meta class.
Using ``ABC`` as a base class has essentially the same effect as specifying
``metaclass=abc.ABCMeta``, but is simpler to type and easier to read.
