• 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)

📦 Next.js Bundle Analysis for react-dev

This analysis was generated by the Next.js Bundle Analysis action. 🤖

⚠️ Global Bundle Size Increased

Page	Size (compressed)
global	116.61 KB (🟡 +2 B)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis
