This will be available in FastAPI 0.65.0, released in a couple of hours.

Let's give the author a few hours here.

Also there is https://github.com/tiangolo/fastapi/releases/tag/0.64.0 (3 days ago), so even if we would go with the patch an update would be appropriate.

And here we are.

Did urllib3 somehow change in Python 3.9 in a way such that local networking doesn't work in the sandbox anymore?

urllib3.exceptions.NewConnectionError: <urllib3.connection.HTTPConnection object at 0x7ffff50a5f70>: Failed to establish a new connection: [Errno 111] Connection refused

Never mind, it works now. Though the test looks a little flaky:

LGTM, save for the leftover pythonAtLeast.
