http://docs.python.org/dev/3.0/whatsnew/3.0.htmlReleased yesterday, Python 3.0 (or Python 3000) brings many new features to the table and discards numerous deprecated ones. Even the syntax has changed slightly. So this new version of Python will be backwards-incompatible with previous releases, though it's a lot cleaner and more elegant. Tools exist to convert Python 2.x code to Python 3.0, though manual conversion should not be too difficult. What do you think about Py3K?
