Abstract

This document describes the Python 2.2 development and releaseschedule. The schedule primarily concerns itself with PEP-sizeditems. Small bug fixes and changes will occur up until the firstbeta release.

Release Manager

Barry Warsaw was the Python 2.2 release manager.

Release Mechanics

We experimented with a new mechanism for releases: a week beforeevery alpha, beta or other release, we forked off a branch whichbecame the release. Changes to the branch are limited to therelease manager and his designated ‘bots. This experiment wasdeemed a success and should be observed for future releases. SeePEP 101 for the actual release mechanics.
