Discussions on Python.org · The 3.14 branch is locked for RC1The 3.14 branch is now locked for all (except release managers and admins) until the 3.14.0 final release (scheduled for 2025-10-07). Reminder from the devguide: A branch preparing for an RC release can only have bugfixes applied that have been reviewed by other core developers. Generally, these issues must be severe enough (for example, crashes) that they deserve fixing before the final release. All other issues should be deferred to the next development cycle, since stability is the stronge...

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!

Details:
discuss.python.org/t/pep-779-c

Discussions on Python.org · PEP 779: Criteria for supported status for free-threaded PythonHi Thomas, The Steering Council (SC) approves PEP 779, with the effect of removing the “experimental” tag from the free-threaded build of Python 3.14. Along with this, the SC considers the following requirements must be addressed during Phase II. Meeting these ensures that free-threading support can mature into a safe and scalable default in future versions of Python. This is not an exhaustive list, and any other previous requirements should still be met. C API/ABI compatibility and Stable ...

Discussions on Python.org · PEP 734: Multiple Interpreters in the StdlibAfter discussing PEP 734 before and during PyCon, with you and many others, and confirming with @hugovk that he will issue a feature freeze exception for Python 3.14, the Steering Council approves PEP 734, with one suggested change (see below). The Python community is incredibly grateful for your diligence, tenacity, and expertise in bringing the subinterpreters feature to fruition. Despite the Zen of Python’s “There’s Only One Way To Do It”, we believe that giving Python developers options fo...

#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.

🚀 Oh, great! Python 3.14 is here to save us from the perilous clutches of f-strings with the magical invention of t-strings. Because, obviously, what we need is yet another way to format strings and confuse everyone even more. 🙄 Let's just hope nobody f-misuses these t-strings to launch SQL attacks straight from their keyboards. 💥
