On behalf of the Python development team, I'm happy as a lark to announce the
third bugfix release for the Python 3.1 series, Python 3.1.3.

This bug fix release features numerous bug fixes and documentation improvements
over 3.1.2.

The Python 3.1 version series focuses on the stabilization and optimization of
the features and changes that Python 3.0 introduced.  For example, the new I/O
system has been rewritten in C for speed.  File system APIs that use unicode
strings now handle paths with undecodable bytes in them. Other features include
an ordered dictionary implementation, a condensed syntax for nested with
statements, and support for ttk Tile in Tkinter.  For a more extensive list of
changes in 3.1, see http://doc.python.org/3.1/whatsnew/3.1.html or Misc/NEWS in
the Python distribution.

This is a production release. To download Python 3.1.3 visit:
