Python 3.9.0 is almost ready. This release, 3.9.0rc2 , is the last planned preview before the final release of Python 3.9.0 on 2020-10-05. Get it here:

In the mean time, we strongly encourage maintainers of third-party Python projects to prepare their projects for 3.9 compatibility during this phase. As always, report any issues to the Python bug tracker.

Please keep in mind that this is a preview release and its use is not recommended for production environments.

Information for core developers

The 3.9 branch is now accepting changes for 3.9.1. To maximize stability, the final release will be cut from the v3.9.0rc2 tag. If you need the release manager to cherry-pick any critical fixes, mark issues as release blockers and/or add him as a reviewer on a critical backport PR on GitHub.

To see which changes are currently cherry-picked for inclusion in 3.9.0, look at the short-lived branch-v3.9.0 on GitHub.
