19.2.0 (October 1st, 2025)

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

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

All Changes

React

• <Activity /> was developed over many years, starting before ClassComponent.setState (@​acdlite @​sebmarkbage and many others)
• Stringify context as "SomeContext" instead of "SomeContext.Provider" (@​kassens #33507)
• Include stack of cause of React instrumentation errors with %o placeholder (@​eps1lon #34198)
• Fix infinite useDeferredValue loop in popstate event (@​acdlite #32821)
• Fix a bug when an initial value was passed to useDeferredValue (@​acdlite #34376)
• Fix a crash when submitting forms with Client Actions (@​sebmarkbage #33055)
• Hide/unhide the content of dehydrated suspense boundaries if they resuspend (@​sebmarkbage #32900)
• Avoid stack overflow on wide trees during Hot Reload (@​sophiebits #34145)
• Improve Owner and Component stacks in various places (@​sebmarkbage, @​eps1lon: #33629, #33724, #32735, #33723)
• Add cacheSignal (@​sebmarkbage #33557)

Greptile Summary

This PR bumps react and react-dom from 18.2.0 to 19.2.6 in the root package.json (devDependencies used by Storybook/tests), and from 19.2.5 to 19.2.6 in docs-src/package.json. The pnpm-lock.yaml is updated consistently throughout.

• Root package.json: Both react and react-dom move from 18.2.0 → 19.2.6 together, eliminating the major-version gap that existed in an earlier iteration of this PR.
• docs-src/package.json: Both packages move from 19.2.5 → 19.2.6 in lockstep, keeping the Docusaurus site on the latest patch release.
• pnpm-lock.yaml: All resolved peer-dependency strings referencing react@18.2.0, react-dom@18.2.0, and react@19.2.5/react-dom@19.2.5 are updated to react@19.2.6/react-dom@19.2.6 with no stale references remaining.

Confidence Score: 5/5

Safe to merge — all React packages are now consistently versioned and the lockfile has no stale entries.

This is a pure dependency bump with no application logic changes. Both react and react-dom are in lockstep at 19.2.6 across all package manifests, and the lockfile is fully regenerated to match. The previous version mismatches flagged in earlier review rounds have been resolved.

No files require special attention.
