The Python test suite now pass on Alpine Linux (musl C library): discuss.python.org/t/the-python... I increased the stack size to 1 MiB and skipped the few tests known to fail on musl.

I wrote about the stuff I got up to during the Sovereign Tech Fellowship pilot last year. Turns out it was a lot! Expect more this year! hugovk.dev/blog/2026/so... #Python #SovereignTechFellowship @sovereign.tech

It's the 11th of the month! This episode of Things I Learned While Looking Up Other Things is more like Things I Learned While Looking AT Other Things (lots of art, plus unusual rocks, stereotypical names in pastoral poetry, and victories that aren't). buttondown.com/thingslearne...

I’m really honoured and excited to be one of the fellows supported by @sovereign.tech this year 😊. Looking forward to meeting the other fellows, learning about their projects, and contributing to the open source ecosystem together.

After our successful pilot last year, I'm very excited to not only rejoin the 2026 Sovereign Tech Fellowship, but also that @georgically.bsky.social and @stan.ulbrych.org are also joining! Plus looking forward to meeting the other new Fellows! #SovereignTechFellowship

Thanks to @sethmlarson.dev we have a new #Python security policy. I like how it starts: "Python Security Response Team (PSRT) members balance this work against many other responsibilities. Please be thoughtful about the time and attention your report requires." devguide.python.org/security/pol...

Little change to the docs.python.org/3/ homepage: It's no longer an HTML <table>, but <ul> lists with CSS to make a grid. A <table> is for tabular data not layout. This improves accessibility and looks better on mobile. dequeuniversity.com/rules/axe/4.... #Python #docs #accessibility #a11y

OSS burnout claims another project. On 2 Apr, an entitled user angrily asked the burned-out maintainer of nvim-treesitter to “go switch to something that doesn't require interacting with people”. The maintainer replied “OK” — and archived the repo, stopping development of nvim-treesitter.

📰 Now that we're on the tail end of #PyConUS, Core Dispatch #4 is out! 3.15.0 beta 1 shipped, the main branch is open for 3.16, PEP 788 landed, free-threaded builds picked up thread-safe iterator support, and more. Catch up on the last two weeks in CPython 👇 coredispatch.xyz/editions/4

Open source maintainers at profitable companies: stop asking permission to fix what your employer already depends on. No paperwork. No programme. No manager’s blessing. Just maintain it on the clock.

Always love seeing the Pacman rule at the #PyconUS intro. If you want to read more, see my blog post from 9 (!) years ago. www.ericholscher.com/blog/2017/au...

Do not use pull_request_target. Do not use caches in publish workflows. Use dependency cooldowns. Use Zizmor. Tell GitHub to make Actions secure by default. #GitHub #GitHubActions

Hey #Python library maintainers! 👋 I sometimes see pull requests from well-meaning users about bumping minimum versions of dependencies to "fix #security vulnerabilities". Here's a resource you can link to about why this strategy doesn't work in practice: sethmlarson.dev/library-vers...

My Python 3.15 what's new post is out for the just-released 3.15 beta 1! iscinumpy.dev/post/python-...

I'm the first Canadian and the first woman to serve as release manager, and that fucking rocks.

Python 3.15 beta 1 is here 🎉! This means that 3.16 (my first release as RM) is in development! Not to be sappy but this is such an honour. The trust the team has in me is not lost on me. I will do my best to make sure that 3.16 is the best Python yet. 🖤 discuss.python.org/t/python-3-1...

Just as importantly! After two years, it's now time to ceremoniously hand over the `main` branch to @savannah.dev! `main` is now accepting new features for Python 3.16, and I bet it's going to be even better than 3.15. peps.python.org/pep-0826/ #Python #Python315 #Python316
