Abstract
========

This document describes the development and release schedule for
Python 3.4.  The schedule primarily concerns itself with PEP-sized
items.

.. Small features may be added up to the first beta
   release.  Bugs may be fixed until the final release,
   which is planned for March 2014.


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

- 3.4 Release Manager: Larry Hastings
- Windows installers: Martin v. Löwis
- Mac installers: Ned Deily / Ronald Oussoren
- Documentation: Georg Brandl


Release Schedule
================

The releases so far:

- 3.4.0 alpha 1: August 3, 2013
- 3.4.0 alpha 2: September 9, 2013
- 3.4.0 alpha 3: September 29, 2013
- 3.4.0 alpha 4: October 20, 2013
- 3.4.0 beta 1: November 24, 2013
- 3.4.0 beta 2: January 5, 2014

(Beta 1 is also "feature freeze"--no new features beyond this point.)

The anticipated schedule for future releases:

- 3.4.0 beta 3: January 26, 2014
- 3.4.0 candidate 1: February 9, 2014
- 3.4.0 candidate 2: February 23, 2014
- 3.4.0 final: March 16, 2014

.. don't forget to update final date above as well

These are the days we expect to release the software;
Python core developers should note that the revision
used for the release will generally be "tagged" the day
before.  However the actual availability of the release
for download on python.org depends on the schedules of
the crew and the existence of any release-blocking issues.

Since posting the original schedule, we've added "beta 3" and slipped
the subsequent releases by three weeks.  This is because of last-minute
changes due to adoption of "Argument Clinic".  The extra beta will
give these changes extra time to mature.
