On behalf of the Python development team, I'm chuffed to announce the a release
candidate of Python 2.7.1.

Please test the release candidate with your packages and report any bugs you
find.  2.7.1 final is scheduled in two weeks.

2.7 includes many features that were first released in Python 3.1. The faster io
module, the new nested with statement syntax, improved float repr, set literals,
dictionary views, and the memoryview object have been backported from 3.1. Other
features include an ordered dictionary implementation, unittests improvements, a
new sysconfig module, auto-numbering of fields in the str/unicode format method,
and support for ttk Tile in Tkinter.  For a more extensive list of changes in
2.7, see http://doc.python.org/dev/whatsnew/2.7.html or Misc/NEWS in the Python
