Detailed Description

We would like to upgrade Python to 3.11 in Fedora 37 thus we are proposing this plan early.

See the upstream notes at Features for 3.11 and What's new in 3.11.

Important dates and plan

• 2021-05-03: Python 3.11 development begins
• 2021-10-04: Python 3.11.0 alpha 1
  • Package it as python3.11 for testing purposes
  • Start the bootstrap procedure in Copr
  • Do a mass rebuild against every future release in Copr
• 2021-11-02: Python 3.11.0 alpha 2
• 2021-12-06: Python 3.11.0 alpha 3
• 2022-01-03: Python 3.11.0 alpha 4
• 2022-02-02: Python 3.11.0 alpha 5
• 2022-02-09: Branch Fedora 34, Rawhide becomes future Fedora 35
  • The earliest point when we can start rebuilding in Koji side-tag
• 2022-02-28: Python 3.11.0 alpha 6
• 2022-04-05: Python 3.11.0 alpha 7
• 2022-05-06: Python 3.11.0 beta 1
  • No new features beyond this point
• 2022-05-30: Python 3.10.0 beta 2
  • The ideal point when we can start rebuilding in Koji
• 2021-05-31: Expected side tag-merge (optimistic)
• 2022-06-16: Python 3.11.0 beta 3
• 2021-06-25: Expected side tag-merge (realistic)
• 2022-07-09: Python 3.11.0 beta 4
• 2021-07-17: Expected side tag-merge (pessimistic)
• 2021-07-21: Fedora 35 Mass Rebuild
  • The mass rebuild happens with fourth beta. We might need to rebuild Python packages later in exceptional case.
  • If the Koji side-tag is not merged yet at this point, we defer the change to Fedora 36.
• 2022-08-01: Python 3.11.0 candidate 1
  • This serves as "final" for our purposes.
• 2021-08-10: Branch Fedora 35, Rawhide becomes future Fedora 36
• 2021-08-10: Fedora 33 Change Checkpoint: Completion deadline (testable)
• 2021-08-24: Fedora Beta Freeze
  • If rebuild with 3.10.0rc1 is needed, we should strive to do it before the freeze - there is a window of 3 weeks.
• 2022-09-05: Python 3.11.0 candidate 2
• 2021-09-19: Fedora 35 Beta Release (Preferred Target)
  • Beta will likely be released with 3.10.0rc2.
• 2021-09-21: Fedora 35 Beta Target date #1
• 2022-10-03: Python 3.11.0 final
• 2021-10-05: Fedora 35 Final Freeze
  • We'll update to 3.10.0 final using a freeze exception.
• 2021-10-19: Fedora 35 Preferred Final Target date
• 2021-10-26: Fedora 35 Final Target date #1

(From Python 3.10 Release Schedule and Fedora 35 Release Schedule.)

The schedule might appear somewhat tight for Fedora 35, but Python's annual release cycle was adapted for Fedora and this worked fine for Python 3.9 and Fedora 33. It is now common that Python is upgraded on a similar schedule in every odd-numbered Fedora release.

Note that upstream's "release candidates" are frozen except for blocker bugs. Since we can and will backport blocker fixes between Fedora and upstream, we essentially treat the Release Candidate as the final release.
