@jquast can we move forward with it?

[jquast]

Yes, we can move forward with this this week after the next release that includes #120 if there is such sincere interest from so many developers.

Do not mind about bringing the branch up to date, I will do that. Thank you for your effort @hugovk.

Hi, checking in one year later and resolved the conflict :)

Looks like the Windows failures are caused by a GitHub bug: actions/setup-python#1034 Hopefully they'll fix it soon.

@hugovk feel free to use my new action approach for this: aio-libs/frozenlist#622 + aio-libs/frozenlist#633. I'm planning to keep it alive because I've been wanting a better cache control anyway.

[hugovk]

Thanks, we're not in a rush with this PR, because we're still pending #120 and a release before looking at this one, so I think we can wait a bit longer.

[webknjaz]

@hugovk fair! I just saw your back reference and realized I forgot to post about it over on the GH tracker. Did that just now.

[jquast]

Just checking in that yes, we can finally drop 2.7 for an upcoming release this week or so, I have deferred/put #120 back into draft for now
