  • Fragment Refs: Add Refs to <Fragment /> to support composable platform behavior (@ jackpope, @ sebmarkbage, @ eps1lon, @ Dhakshin2007, @ chirokas, @ teamleaderleo, @ fallintoplace: #32465, #32613, #32619, #32654, #32660, #32682, #32722, #32813, #32814, #33056, #33058, #33093, #34069, #34103, #34544, #34545, #37062, #37061, #37060, #36047, #36010, #35642, #35641, #35637, #35630, #34935, #37457, #37408, #37326, #37251, #37171, #37169, #37168, #37167, #37166, #37165, #37164, #37163, #37162, #37161, #37160, #37125, #37063)

  New React DOM Features

  • browser(): a new react-dom API that returns a usable which errors during server rendering and resolves in the browser. use(browser()) inside a <Suspense> boundary marks a subtree as browser-only without reporting a recoverable error (@ gnoff: #37143, #37241)
    • Added an onBrowserBailout option to the react-dom/server APIs to observe when a subtree defers to the browser (@ gnoff #37193)

  Notable changes

  • Enable Trusted Types API integration (@ rickhanlonii #35816)
  • Transitions now render independently instead of being entangled into a single render, so a slow transition no longer holds up unrelated ones (@ acdlite #37290)
  • Added a DEV-only warning when a component appears to have been unblocked by calling use() conditionally (@ hoxyq, @ eps1lon: #37104, #37203, #37491)

[Power-Maverick]

This is a minor version upgrade that introduces new features and bug fixes without any documented breaking changes. According to React's semantic versioning, breaking changes are reserved for major releases.

Key Additions:

• Stable Features: Two previously experimental APIs, <ViewTransition> and Fragment Refs, are now stable and ready for production use.
• New React DOM Features: The release adds support for the browser's Trusted Types API to enhance security and introduces a use(browser()) hook to opt components out of server-side rendering.
• Bug Fixes: Includes several bug fixes, such as for useDeferredValue, context propagation with Suspense, and a crash related to View Transitions on Mobile Safari.

No migration is required, as all new features are additive.
