@jamesls in https://github.com/aws/chalice/issues/2015 you mentioned that Challice is still being supported.

Any chance we can get this Python 3.10 upgrade reviewed and merged?

I successfully used this branch to deploy a 3.10 lambda function.

Thanks for the PR, looks like all the CI is passing for 3.10, going to pull it down locally and try it out.

Any update on this @jamesls? This is the last blocker for updating my whole stack to 3.10

@jamesls Not to rush you, just wondering if there's a timeline for how long after a merge like this we can expect to see it in pypi?

[jamesls]

Version 1.29.0 is now released, which includes this PR.
