# React 19.2 – React

**[React](https://daily.dev/sources/react)** · 8 min read · 2 upvotes · 0 comments

## Summary

React 19.2 introduces the Activity component for controlling and prioritizing app sections, useEffectEvent hook for separating event logic from effects, and cacheSignal for cache lifetime management. The release adds Partial Pre-rendering capability for serving static content from CDN while resuming dynamic rendering later, and includes new Chrome DevTools performance tracks for better profiling. Notable improvements include batched Suspense boundary reveals for SSR, Web Streams support in Node.js, eslint-plugin-react-hooks v6 with flat config, and updated useId prefix to support View Transitions.
