We've upgraded [ui.JGuang UI.com](/systems/jguang-ui#open-source-attribution) to Next.js 15.3 and Tailwind v4. The site now uses the upgraded `new-york` components.

We've also made some minor design updates to make the site faster and easier to navigate.

This upgrade unlocks a lot of new features that we're working on. More to come.
