At the same time, I’m working with the community on a detailed definition of Python 3000; there’s a new mailing dedicated to Python 3000 and a series of PEPs, starting with PEP 3000.

This work is still in the early stages. Some changes, such as removing classic classes and string exceptions, adopting Unicode as the only character type, and changing integer division so that 1/2 returns 0.5 instead of truncating toward zero, have been planned for years.
