Finally, we've improved text rendering (again!). Especially light mode looks a lot better. Before/after:

SVG support has been greatly improved. We now have pixel-perfect scalable vector graphics. Yay :)

On a related note, the next Rerun release switches all its icons to SVGs ;)

egui::Atom is the new, indivisible building block of egui (hence the name). It lets you mix images and text in many places where you would previously only be able to add text.

Atoms is the first step towards a more powerful layout engine in egui - stay tuned!

Anyone wants to work on some clippy lints? :)

@github.com Please step up your anti-spam game. Having to manually mark hundreds of issues as "Not planned" is not a fun way to start my Saturday 😡

The new crates.io theme feels a bit unbalanced: crates.io/crates/egui/...

I added a little tessellation playground in order to get the rendering juuuuust right. Try it out on egui.rs!

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!

Using egui_kittest for screenshot tests is an absolute game changer

The next version of egui will have much sharper lines and rectangles, because they will be aligned to pixel boundaries. Before/after

egui 0.30 also adds support for modals, and many other smaller things

We implemented undo in @rerun.io by storing the viewer state in the same type of in-memory database we use for the recorded data. Have a look (sound on!)

Every time I start Discord I have to sit through this screen. Why does the Discord devs punish me for opening their app?

That was supposed to be an animated GIF - I guess bluesky doesn't support such modern tech O.o
Let's try an .mp4 instead
