@hugovk congratulations on the compatibility of Python 3.14 beta. This repo contains tested Python algorithms spanning lots of domains and third-party libraries from a huge variety of contributors. We always test and run on the current version of CPython and when each beta 1 release ships I port to it making any required changes.

Of all the upgrades that I have done, Python v3.14 is by far the cleanest and simplest!! Third party tools like SciPy, Pillow, and H5py all seem ready to go. This has never been the case before so I suspect that you have been doing a lot of behind-the-scenes work to ensure everyone is ready for a great release.

We needed to rename our compression directory (#12725) and change the text of a few exceptions, but these were trivial changes. radix2_fft.py requires doctest changes that I cannot understand, but for an initial beta, I am very impressed.

Thanks and congratulations 🎉🎈🍾

Good to hear, thank you! And thank you for the early testing :)

Personally I've only been involved with Pillow, but I suspect much of it is down to the excellent work done by the Quansight team helping projects get ready for free-threading, which overlaps getting ready for 3.14. cc @ngoldbaum@lysnikolaou
