Release date: Feb. 13, 2009

Python 3.0.1 was released on February 13, 2009. It was a bugfix release of Python 3.0.

This is the first bugfix release of Python 3.0. Python 3.0 is now in bugfix-only mode; no new features are being added. Dozens of bugs that were reported since the release of 3.0 final have been fixed.

Python 3.0 (a.k.a. "Python 3000" or "Py3k") 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.

[1]	The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64).
