Hello ! Any news on that ? Do you need any help for it ?

Are you asking me or @tiangolo? I think the PR is finished and only needs to be checked and merged, which I cannot do.

[alexisdurieux]

I am asking both, let me know if I can help get this merged =)
Should we rerun the tests if its done ?

[kolypto]

Looks like a pretty straightforward change. @tiangolo , do you think it's ready to be merged?

[wewelll]

@tiangolo let's merge this ?

[alexeyshockov]

@tiangolo, any blockers? Tell if help needed here, it would be really awesome to have 3.9 support.

Created another PR #64 which fixes build errors in python3.9 images of this PR.

In case you need, built images are available in DockerHub (see links in the mentioned PR)

Thanks @graue70! 🍰

I updated and refactored several parts a bit and it's ready now.

Thanks for the interest everyone! This is now released and available. 🚀 🎉
