React 19.2 is here: Activity API, useEffectEvent and more
SMRTR summary
React 19.2 has launched with two major features: the Activity API and the useEffectEvent Hook. The Activity API allows components to be hidden while preserving their internal state, making it ideal for tabbed interfaces and modals, while useEffectEvent lets developers create stable event handlers that access the latest state without triggering unnecessary effect reruns. The update also includes performance improvements like partial pre-rendering, batched server-side rendering, and new Chrome DevTools integration for better performance tracking.
