Thanks for the PR @themegaphoenix!

We have a not-exactly-short-term but also not-exactly-long-term goal to bring platform support for the Python driver (and perhaps other drivers as well) up-to-date with current platforms. At the moment this effort is most clearly expressed in PYTHON-1283 but there is other work going on as well. Validating a release requires extensive testing (and likely a bug fix or two) but please keep an eye on that ticket for updates.

In the meantime we are working on making wheels for 3.9 and 3.10 available. This is not to say that we officially support either of these runtimes yet but we are aware that the driver is used on these Python versions so we're trying to make that process easier. You can track that work at PYTHON-1295.

Thanks again!

@absurdfarce There's a (at least) one bug in Python 3.10 where in AsyncioConnection the Queue is getting a outdated argument called loop:

self._write_queue = asyncio.Queue(loop=self._loop)

This raises an exception:

TypeError: As of 3.10, the *loop* parameter was removed from Queue() since it is no longer necessary

Note for future readers: @fabiopedrosa filed PYTHON-1313 to describe the issue above. This issue has subsequently been converted into a subtask of PYTHON-1283 which is the overarching ticket for 3.9 and 3.10 compatibility work.
