Just released: Python 3.14.0 beta 3!
All the good stuff of b2 but also:
Free-threaded Python is officially supported! (PEP 779)
Subinterpreters in the stdlib! (PEP 734)
Do you maintain a Python package? Please test 3.14.
If you find a bug now, we can fix it before October, which helps everyone. And you might find some places in your code to update as well, which helps you.

Yes, let's test our projects with free-threaded in CI! Here's how to do it with GitHub Actions:

Exciting news!
PEP 779 ("Criteria for supported status for free-threaded Python") has been accepted, which means free-threaded Python is now a supported build!
We'll drop the "experimental" label already in 3.14 beta 3, due on Tuesday!

#Python 3.14.0 beta 1 release day! `main` branch is locked!
It's also the feature freeze, meaning lots of stuff got merged yesterday so it can be released in 3.14 in October 2025 and not 3.15 in October 2026. But first, a couple of reverts for not-so-important things that weren't quite ready and last-minute fixes.
Less than one week to:
Python 3.14 beta! This marks the feature freeze, when we stop adding ~~bugs~~ features and begin a five-month stabilisation period, where we need you to start testing and reporting bugs.
https://peps.python.org/pep-0745/
Forget 3.14 (please don't, please test), Python 3.15 development begins! Check out the freshly published release PEP (where I make a commitment to release until 2031...):
Here's a good intro to Python 3.14's t-strings by @davepeck, one of the authors of PEP 750 https://davepeck.org/2025/04/11/pythons-new-t-strings/
