Abstract

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

Release Manager and Crew

-   Windows installers: Steve Dower
-   Mac installers: Ned Deily
-   Documentation: Julien Palard

3.7 Lifespan

3.7 will receive bugfix updates approximately every 3 months for about
24 months. Sometime after the release of 3.8.0 final, a final 3.7 bugfix
update will be released. After that, it is expected that security
updates (source only) will be released as needed until 5 years after the
release of 3.7 final, so until approximately 2023-06.

As of 2023-06-27, 3.7 has reached the end-of-life phase of its release
cycle. 3.7.17 was the final security release. The code base for 3.7 is
now frozen and no further updates will be provided nor issues of any
kind will be accepted on the bug tracker.
