Hi :-) Did you discuss at some point a policy which Python versions you want to support? I see that scikit-learn supports at the moment 3.6, 3.7, and 3.8 (badge in README). In a couple of weeks (October?) there will be 3.9, but I don't see any issue opened discussing 3.9
A minor python increment (e.g. 3.8 -> 3.9) will now happen every year, IIRC. So maybe it would be nice to just say "we support the latest 3 Python versions". In the very least, this would mean that wheels are published and that the CI pipeline is run for the newer versions. I think it would also be nice to "deprecate" old features and drop support explicitly. For example, if scikit-learn dropped support for 3.6 we could use future annotations. The implication of such a drop of support would be a major version increase. Best regards, Martin
