On behalf of the Python development team and the Python community, I'm
happy to announce the first alpha release of Python 3.1.

Python 3.1 focuses on the stabilization and optimization of features and changes
Python 3.0 introduced.  The new I/O system has been rewritten in C for speed.
Other features include a ordered dictionary implementation and support for ttk
Tile in Tkinter.

Please note that these are alpha releases, and as such are not suitable for
production environments.  We continue to strive for a high degree of quality,
but there are still some known problems and the feature sets have not been
finalized.  These alphas are being released to solicit feedback and hopefully
discover bugs, as well as allowing you to determine how changes in 3.1 might
impact you.  If you find things broken or incorrect, please submit a bug report

For more information and downloads, see the Python 3.1 website:

See PEP 375 for release schedule details:
