Hot take: All Rust repos should have Cargo.lock in git together with a `.gitattributes` file containing:
Cargo.lock linguist-generated=false
This makes the diff of Cargo.lock show up in GitHub PRs

Noooooo it was egui 0.31 that got released today. OH THIRTY ONE
Introducing egui 0.30!
This adds `egui::Scene`: a pannable, zoomable container for other UI elements.
This release also makes frames and corner radius more in line with how CSS and Figma works.
We’ve also improved the crispness of the rendering, and a lot more!

The next egui release adds `egui::Scene`, that lets you pan and zoom any contents. I think this will be really useful for things like node graphs!

We’re building a new static type checker for Python, from scratch, in Rust.
From a technical perspective, it’s probably our most ambitious project yet. We’re about 800 PRs deep!
