Python 3.1 is out

As Benjamin Peterson tweeted, Python 3.1 is now available. As always you can read about what's new. Anyone using Python 3 for anything should upgrade as there are some major performance improvements in 3.1 that will make your life better (that includes the new --with-computed-gotos configure flag).

And just to remind people, PEP 370 exists to help you manage your Python installation.
