Below is a list of all new features, APIs, and bug fixes.

Read the React 19.2 release post for more information.

New React Features

<Activity>: A new API to hide and restore the UI and internal state of its children.
useEffectEvent is a React Hook that lets you extract non-reactive logic into an Effect Event.
cacheSignal (for RSCs) lets your know when the cache() lifetime is over.
React Performance tracks appear on the Performance panel’s timeline in your browser developer tools

New React DOM Features

Added resume APIs for partial pre-rendering with Web Streams:
- resume: to resume a prerender to a stream.
- resumeAndPrerender: to resume a prerender to HTML.
Added resume APIs for partial pre-rendering with Node Streams:
- resumeToPipeableStream: to resume a prerender to a stream.
- resumeAndPrerenderToNodeStream: to resume a prerender to HTML.
Updated prerender APIs to return a postponed state that can be passed to the resume APIs.

Notable changes

React DOM now batches suspense boundary reveals, matching the behavior of client side rendering. This change is especially noticeable when animating the reveal of Suspense boundaries e.g. with the upcoming <ViewTransition> Component. React will batch as much reveals as possible before the first paint while trying to hit popular first-contentful paint metrics.
Add Node Web Streams (prerender, renderToReadableStream) to server-side-rendering APIs for Node.js
Use underscore instead of : IDs generated by useId
