A preview of the new version of the Python language has been released. 3.0a1 is an early alpha based on the PEPs created for what has been internally called 'Python3000', which embodies the next generation of the popular language used extensively by Google and NASA, among others. Python 3.x will be incompatible (by design) with the 2.x line, since much of the crud accumulated and deprecated over the last few years has now been removed (the 2.x versions will continue to be patched, but not enhanced). More information about the release can be found on Guido van Rossum's blog.
