Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry.

We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".

The Python Steering Council is pleased to announce that the Free-Threading project is no longer considered experimental!

Just published the blog posts for the #Python Language Summit 2025. It's quite fun to cover this important event and contribute to the Python community in this unique way :)

Please take a look if you weren't able to attend the Language Summit in person:

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust.

In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

@thepsf.bsky.social Developers-in-Residence Program now has a landing page! 💜

Today we cover the language runtime and security work, maybe there's a gap in the #Python ecosystem your organization wants to see improved? Let's chat!

🎉 Yeah, uv 0.6.15 supports PEP751, pylock.toml with
• uv export -o pylock.toml
• uv pip compile -o pylock.toml -r requirements.in
• uv pip sync pylock.toml
• uv pip install -r pylock.toml

BREAKING! Guido van Rossum, the legendary creator of #Python, has officially reinstated himself as Benevolent Dictator for Life (BDFL).

Stay tuned for the documentary coming this summer!

PEP 751 has been accepted! peps.python.org/pep-0751/

This means #Python now has a lock file standard that can act as an export target for tools that can create some sort of lock file. And for some tools the format can act as their primary lock file format as well instead of some proprietary format.

I FINALLY asked for pronouncement on PEP 751 -- lock files for #Python : peps.python.org/pep-0751/ .

I spent last week in Valtournenche with @antocuni.bsky.social and Hood Chatham and managed to use SPy to accelerate my #Python code in the browser. It's too early for general adoption, but not too early to get excited!

📦 Just released sbommage, a friendly terminal UI for exploring SBOMs! Built with Python/Textual, it handles SPDX, CycloneDX, and Syft formats. Works great for quickly poking around in your SBOMs without fighting with JSON viewers.
