Just as importantly!
After two years, it's now time to ceremoniously hand over the `main` branch to @savannah!
`main` is now accepting new features for Python 3.16, and I bet it's going to be even better than 3.15.

Please report bugs, we'll fix for the big October release.
It’s the first beta and feature freeze! This is a beta preview of Python 3.15 Python 3.15 is still in development. This release, 3.15.0b1, is the first of four planned beta releases. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage maintainers of third-party Python projects to test with 3.15 during the beta phase and report issues found to...

Today is the scheduled release date for Python 3.15.0 beta 1. I’ll lock the main branch after posting this, so we can get the last few things in and let the CI and buildbots settle down and finish testing everything that will go into 3.15 before I start the release process. If you have anything urgent you really want to get into 3.15 beta 1, let me know right now, either in this thread, or on the Core Team Discord, or email (hugo at python). (I don’t just mean after I lock down the main branch,...
Release week update!
Also moving release 3/3 this week, 3.14.5 final, by a couple of days to give some more time for testing of the RC 🚀
https://discuss.python.org/t/python-3-14-5-release-candidate/107185/2
Current plan:
✅ 3.14.5rc1 on Monday 4nd (+2 days)
⬜ 3.15.0b1 on Thursday 7th (+2 days)
⬜ 3.14.5 final on Sunday 10th (+2 days)
Hey @hugovk, we are working on pushing this rc to Fedora Rawhide (development version), which is not yet updated to 3.15. That should give us some feedback, hopefully, but it will take a while before we get some. If the final is to be released in 2 days, I am afraid we will arrive with feedback (if any) too late.
I'm postponing Python 3.15 beta 1 to Thursday to get the last few things in. We're close!

PEP news!
PEP 831 – Frame Pointers Everywhere: Enabling System-Level Observability for Python
Accepted ✅
"After extensive deliberation the Steering Council has decided to accept PEP 831 (Frame Pointers Everywhere: yahdah yahdah), because it’s clearly the correct and necessary thing… although we wish the PEP and its title had been a lot shorter, given how much of an obvious decision it is. Congrats!"
Days until feature freeze: 4

Well, let's fix those pprint defaults!
