The CI looks good in general. The tests pass locally as well.
The only issue is uvloop: MagicStack/uvloop#637

@bogdanp05 could you please take a look? This one is ready to go.

Actually hold on a sec. I'll bump the python version in other jobs as well

[mkmkme]

I think now it's good to go

[mkmkme]

The latest commit is related to setuptools not being included with Python anymore. We also need to switch to pyproject.toml soon as per #96. I'll reintroduce that change soon, it's going to be released with 6.2.0

Also "Install package from commit hash (3.9)" is expected to hang. I'll remove it from the required status as soon as this PR is merged

"Install package from commit hash (3.9)" is a required check and if it hangs, then auto-merge will never happen

True. I can remove it next week as I'm out until Tuesday) or you can do it yourself if you want :)

[bogdanp05]

you can do it yourself

Done. Note to self: I had to disable it from settings -> branches -> branch protection rules
