Abstract
========

This document describes the development and release schedule for
Python 3.3.  The schedule primarily concerns itself with PEP-sized
items.

.. Small features may be added up to and including the first beta
   release.  Bugs may be fixed until the final release, which is planned
   for September 2012.


Release Manager and Crew
========================

- 3.3 Release Manager: Georg Brandl
- Windows installers: Martin v. Löwis
- Mac installers: Ronald Oussoren/Ned Deily

3.3 Lifespan
============

3.3 will receive bugfix updates approximately every 4-6 months for
approximately 18 months.  After the release of 3.4.0 final, a final
3.3 bugfix update will be released.  After that, security updates
