Python 3000
Python 3000 (a.k.a. "Py3k", and released as Python 3.0) is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. Also, the standard library has been reorganized in a few prominent places.
We released alphas in 2007, betas in 2008, and are planning a few release candidates, with a final release in October 2008. While not ready for production, we highly encourage you to grab the release candidates and test them against your code. At this point, only highly critical bugs will be fixed before the final release.
