Abstract
========

This document describes the development and release schedule for
Python 3.6.  The schedule primarily concerns itself with PEP-sized
items.


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

- 3.6 Release Manager: Ned Deily
- Windows installers: Steve Dower
- Mac installers: Ned Deily
- Documentation: Julien Palard, Georg Brandl


3.6 Lifespan
============

3.6 will receive `bugfix updates <https://devguide.python.org/devcycle/#maintenance-branches>`_
approximately every 3 months for about 24 months. Sometime after the release of
3.7.0 final, a final 3.6 bugfix update will be released.
After that, it is expected that
`security updates <https://devguide.python.org/devcycle/#security-branches>`_
(source only) will be released as needed until 5 years after
the release of 3.6 final, so until approximately 2021-12.

As of 2021-12-23, 3.6 has reached the
`end-of-life phase <https://devguide.python.org/devcycle/#end-of-life-branches>`_
of its release cycle. 3.6.15 was the final security release. The code base for
3.6 is now frozen and no further updates will be provided nor issues of any
kind will be accepted on the bug tracker.
