Improved support for abstract base classes containing descriptors composed with
|
||||||
|
abstract methods. The recommended approach to declaring abstract descriptors is
|
||||||
|
now to provide :attr:`__isabstractmethod__` as a dynamically updated
|
||||||
|
property. The built-in descriptors have been updated accordingly.
|
||||||
|
|
||||||
|
* :class:`abc.abstractproperty` has been deprecated, use :class:`property`
|
||||||
|
with :func:`abc.abstractmethod` instead.
