Today I released Motor 0.3. This version has no new features compared to Motor 0.2.1. Here's what I changed:

• I updated the PyMongo dependency from 2.7 to 2.7.1, therefore inheriting PyMongo 2.7.1’s bug fixes.
• Motor continues to support Python 2.6, 2.7, 3.3, and 3.4, but now with single-source. 2to3 no longer runs during installation with Python 3.
• nosetests is no longer required for regular Motor tests.
• I fixed a mistake in the docs for aggregate().

Rewriting Motor to support Python 2 and 3 in the same source code makes life sane for me, and it reflects the current consensus about the best way to write portable Python. It wasn't terribly difficult either.

Now that I've simplified Motor's Python 3 support, I'm ready to tackle the next big challenge: I want to see if Motor can support Twisted and asyncio, in addition to Tornado. Wish me luck.
