Abstract

This document describes the Python 2.2 development and release schedule.
The schedule primarily concerns itself with PEP-sized items. Small bug
fixes and changes will occur up until the first beta release.

The schedule below represents the actual release dates of Python 2.2.
Note that any subsequent maintenance releases of Python 2.2 should be
covered by separate PEPs.

Release Schedule

Tentative future release dates. Note that we've slipped this compared to
the schedule posted around the release of 2.2a1.

Release Manager

Barry Warsaw was the Python 2.2 release manager.

Release Mechanics

We experimented with a new mechanism for releases: a week before every
alpha, beta or other release, we forked off a branch which became the
release. Changes to the branch are limited to the release manager and
his designated 'bots. This experiment was deemed a success and should be
observed for future releases. See PEP 101 for the actual release
mechanics.
