Sourced from react's releases.

19.2.0 (Oct 1, 2025)

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

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)

React DOM

• Block on Suspensey Fonts during reveal of server-side-rendered content (@​sebmarkbage #33342)
• Use underscore instead of : for IDs generated by useId (@​sebmarkbage, @​eps1lon: #32001, facebook/react#33342#33099, #33422)
• Stop warning when ARIA 1.3 attributes are used (@​Abdul-Omira #34264)
• Allow nonce to be used on hoistable styles (@​Andarist #32461)
• Warn for using a React owned node as a Container if it also has text content (@​sebmarkbage #32774)

⚠ BREAKING CHANGES

• ** L1 resources are automatically generated from public CloudFormation Resource Schemas. They are built to closely reflect the real state of CloudFormation. Sometimes these updates can contain changes that are incompatible with previous types, but more accurately reflect reality. In this release we have changed:

aws-servicecatalog: AWS::ServiceCatalog::PortfolioPrincipalAssociation: PortfolioId property is now required. aws-servicecatalog: AWS::ServiceCatalog::PortfolioPrincipalAssociation: PrincipalARN property is now required. aws-servicecatalog: AWS::ServiceCatalog::PortfolioProductAssociation: Id attribute removed.
