* bpo-43827: Make arguments to abc.ABCMeta.__new__ pos-only (#25385)Vlad Hoi2022-05-051-1/+1
| | | To avoid conflicts with `__init__subclass__`.
* Clarify the order of a stacked `abstractmethod` (GH-26892)Ram Rachum2021-06-271-3/+24

* bpo-41905: Add abc.update_abstractmethods() (GH-22485)Ben Avrahami2020-10-061-0/+38
| | | | This function recomputes `cls.__abstractmethods__`. Also update `@dataclass` to use it.
* bpo-35609: Remove examples for deprecated decorators in the abc module. ↵Serhiy Storchaka2018-12-311-46/+5

* bpo-31333: Re-implement ABCMeta in C (#5273)Ivan Levkivskyi2018-02-181-142/+62
| | | | This adds C versions of methods used by ABCMeta that improve performance of various ABC operations.

* bpo-30463: Add an empty __slots__ to abc.ABC.Aaron Hall, MBA2017-06-061-1/+1
|
* bpo-29581: Make ABCMeta.__new__ pass **kwargs to type.__new__ (#527)Nate2017-03-151-2/+2
| | | | | | | | | | | | | Many metaclasses in the standard library don't play nice with __init_subclass__. This bug makes ABCMeta in particular with __init_subclass__, which is an 80/20 solution for me personally. AFAICT, a general solution to this problem requires updating all metaclasses in the standard library to make sure they pass **kwargs to type.__new__, whereas this PR only fixes ABCMeta. For context, see https://bugs.python.org/issue29581. * added a test combining ABCMeta and __init_subclass__ * Added NEWS item
