Welcome back, I hope you enjoyed Thanksgiving. I certainly did; among everything for which I give thanks this year, I am grateful for the contributions Rémi Jolin, Andrew Svetlov, and Nikolay Novik made to Motor's asyncio integration. Their help is the greatest gift any project of mine has received.
And now, it's official! Motor 0.5 is released. Install it with:
python -m pip install motor
This version of Motor is compatible with Python 2.6 through 3.5, and it can use either Tornado or asyncio. This means pip no longer automatically installs Tornado.
For a detailed description of the changes, read the beta announcement.
