@knipknap, I understand this repo hasn't been updated in a while, but can you look into this PR and merge it. 3.10 and above are becoming the new upstream version of python, and this package just refuses to work without this kind of fix.

Looks good. Thank you!

@knipknap, is there a release planned, that will include this update?

I have the same question. Hope to see new version in PyPI soon!
