On behalf of the Python development team, I'm pleased to announce the first
alpha release of Python 2.7.

Python 2.7 is scheduled to be the last major version in the 2.x series.  It
includes many features that were first released in Python 3.1.  The faster io
module, the new nested with statement syntax, improved float repr, and the
memoryview object have been backported from 3.1. Other features include an
ordered dictionary implementation, unittests improvements, and support for ttk
Tile in Tkinter.  For a more extensive list of changes in 2.7, see
http://doc.python.org/dev/doc/whatsnew/2.7.html or Misc/NEWS in the Python
distribution.  Please note that this is a development release, intended as a
preview of new features for the community, and is thus not suitable for
production use.
