On: Uvloop – Ultra fast implementation of asyncio even...

[1st1]

uvloop is meant to work with asyncio, which requires Python 3. So there is no point in supporting Python 2 (and trollius isn't maintained anymore).

[millisecond → 1st1]

Ah, makes sense. Relatively new to Python world and getting a handle on all the version differences.

[scrollaway → millisecond]

Unless there's a particular software or environment you're using that only supports Python 2, you'll want to deal with Python 3.4 at least.
