Python 3000 is ready! The official release may not come until tomorrow, but Barry has tagged the source and is preparing the release. We've been waiting for this release for almost nine years. The earliest reference I can find is a message from Guido to python-dev in Jan. 2000.
In the previous century, we had been thinking about Python 2 as the Python version that would break backwards compatibility to make real language improvements. Python 2 ended up being a big deal, but without too many compatibility issues. All the major changes were deferred to "Python 3000," a mythical creature. I'm eager to see what programmers make of this creature.
