• `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 (<https://github.com/sophiebi…
