Python 3000 has officially been released. The final bug, Issue2306, “Update What’s new in 3.0″ has been closed. Python 3000, py3k, Python 3.0, is a major release for the community. [Jeremy Hylton] pegs the earliest mention of the beast to January 2000. The new release has grown from PEP 3000, opened April 2006.

Py3k breaks backwards compatibility with previous releases in order to reduce feature duplication and promote one obvious way of getting things done. The first major change is that print is now a builtin function and not a statement. int and long have been unified, and integer division now returns a float. Py3k uses concepts of “text” and “data” instead of “Unicode strings” and “8-bit strings”. You can read about many of the changes in What’s New In Python 3.0. Some new features have been backported to Python 2.6 so you can start implementing them in your current code to ease the transition. 2.6 also has the -3 command line switch to warn you about features that are being removed or changed. Finally, the tool 2to3 is a source-to-source translator that should automate a lot of the changes.

Documentation for the new release is online. Source packages and binaries are available now.
