Support for Python 3.9 #15
Description
The plugin seems to have a manual check for Python versions that it supports. 3.9 is to be released soon. Nose has problems related to importing ABC from collections directly nose-devs/nose#1099 . This change was postponed to 3.10 but might cause more people to migrate to pytest.
Also note that lib2to3 is deprecated since Python 3.10.
