A worthwhile read if you build UIs that need to stay fast at scale, and they're upfront about the mistakes they made along the way.

It’s now at v0.1 with React 19.3 API support, a drop-in Vite plugin, and a useful [compatibility table](https://github.com/TanStack/redact#compatibility). TanStack πŸ’‘ The runtime is a fraction of React's size, but the trade-off is no concurrent rendering ([this Japanese blog post](https://azukiazusa.dev/blog/what-is-tanstack-redact/) has a nice look into that).

[React-Redux 9.4 Alpha Adds Opt-In `useSignalSelector`](https://github.com/reduxjs/react-redux/releases/tag/v9.4.0-alpha.0) β€” Redux runs every mounted selector on every dispatch, which gets costly in huge apps. The new opt-in, signals-based `useSignalSelector` tracks which state each selector reads, so a dispatch only re-runs selectors whose data changed.
