#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.

peps.python.org/pep-0745/

Python PEPs
Python Enhancement Proposals (PEPs)PEP 745 – Python 3.14 Release Schedule | peps.python.orgThis document describes the development and release schedule for Python 3.14.

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.

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...):
