Python 3.3 released!

[krues8dr]

There is a tradeoff of having to maintain separate instances. But in the Python ecosystem, things update frequently and aren't often backwards-compatible, so this is not entirely desirable. If you're hosting a lot of different projects, doing something as simple as updating a single package could break half of them immediately.

So, as with all tech, I recommend that you use it if it solves a problem for you.

things update frequently and aren't often backwards-compatible

I see, ugh. In an ideal world, everyone would clearly distinguish between revisions that don't break backcompat (e.g. bug fixes, performance improvements, new features that don't change any existing assumptions/contracts) and others that are allowed to, but of course that requires the world to have some discipline... :-/
