React 19.3 stabilizes View Transitions and Fragment refs
React 19.3 makes View Transitions and Fragment refs stable. View Transitions coordinate DOM animations with React transitions and Suspense, while Fragment refs expose operations such as focus and observation across sibling elements without inserting a wrapper. The release also adds a browser-only rendering helper that uses a Suspense fallback during server rendering.

Why it matters
Worth reviewing when animation, wrapper elements or browser-only state complicate a React application.
More context
This is catch-up coverage of the September 9 release, available on npm. Try one existing interaction on a branch and check hydration and keyboard focus. The announcement recommends keeping loading fallbacks immediate and avoiding unnecessary animation for cached content.
Keep in mind
View Transitions currently target the DOM, not React Native. Browser support and framework compatibility still matter; 1min reviewed the examples but has not upgraded an application.
