Mercurial broke after today's M2Crypto update

Code:$ hg

AnyStr = TypeVar('AnyStr', bytes, unicode)
NameError: name 'unicode' is not definedThe last file in the trace (/usr/lib64/python3.8/site-packages/typing.py) is part of M2Crypto, which was updated today.

hg is using the python3 interpreter (#!/usr/bin/python3), but "unicode" used in typing.py is python2 only (renamed to 'str' in python3).

Did I break my installation, or is there a problem with the packages?
