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 current betas and test them against your code.
