Their PyPI page explicitly says otherwise: https://pypi.python.org/pypi/supervisor . It looks like there is support in their repository but not in any official release (yet).

You are correct. But the setup.py for Supervisor noted support for Python 3 starting in May of 2014: https://github.com/Supervisor/supervisor/commit/ad5cd0849a5f...

I don't know why PyPI isn't updated yet.
