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)
