A new Python blog post/announcement has been posted!

Not one but two expedited releases! 🎉 🎉

Python 3.14.0rc2

It’s the final 🪄 penultimate 🪄 3.14 release candidate!

Due to this early release, we’ll also add a third release candidate between now and the final 3.14.0 release, with no planned change to the final release date.

This release, 3.14.0rc2, is the penultimate release preview. Entering the release candidate phase, only reviewed code changes which are clear bug fixes are allowed between this release candidate and the final release.

The next pre-release of Python 3.14 will be the final release candidate, 3.14.0rc3, scheduled for 2025-09-16; the official release of 3.14.0 is scheduled for Tuesday, 2025-10-07.

There will be no ABI changes from this point forward in the 3.14 series, and the goal is that there will be as few code changes as possible.

Call to action

We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.14 during this phase, and publish Python 3.14 wheels on PyPI to be ready for t...
