I am proud to share the news that PSF has decided to sponsor the ft-checker.com website. We will continue to enhance the project for the successful landing of the free-threading CPython project!

The "faster CPython" team at Microsoft was recently dissolved. My position at Microsoft was eliminated. If anyone has a reason to be disappointed in this, it's me. So it feels okay for me to ask you to refocus any disappointment you might have about Microsoft's decision.

Let's be grateful for a big Python user actually laying down meaningful cash for 4 years in support of a volunteer-driven community project! Let's express our frustration instead in how that doesn't happen more often!

I've been working on CPython's JIT compiler from the very start. Here are some reflections I have on it. Some points are hard to swallow, but I have to point them out if we are to grow. fidget-spinner.github.io/posts/jit-refl…

How well do you know Python’s f-strings? I built a thing inspired by JavaScript’s Date constructor quiz but for Python. fstrings.wtf

We just released cibuildwheel 3.1, which builds Python 3.14/3.14t wheels by default (with yesterday's RC 1)! Also we added Android support, Pyodide 0.28 (3.13), 32-bit modern manylinux, riscv64 defaults, and beautiful new summaries! github.com/pypa/cibuildwh…

A campaign targeted GitHub Actions to steal PyPI tokens—PyPI wasn’t compromised and no PyPI packages were published by the attackers. Stay safe: review your tokens, rotate any exposed ones, and use short-lived, scoped GitHub Actions tokens. Details: blog.pypi.org/posts/2025-09-…

🐍 Throwback to last month’s CPython Core Dev Sprint 2025 at our HQ in Cambridge. 50+ core devs (yes, including Guido 👀) and guests spent 5 days hacking on CPython: think working with JIT, free-threading, C-API and more. Thanks to Python Software Foundation + everyone who joined:
