React 19.3 makes View Transitions and Fragment Refs stable
React 19.3, released Wednesday, promotes View Transitions and Fragment Refs from experimental APIs to stable features. The former coordinates animations with transition updates; the latter lets code handle a group of DOM children without adding a wrapper element. The release also introduces a browser-only rendering escape hatch and preserves Trusted Types values passed to DOM APIs. These are concrete framework changes, with platform limits and migration details covered in the React team's release notes.
Editorial summary · Publisher article
What matters
- View Transitions currently support the DOM; urgent updates outside transitions do not trigger their animations.
- Fragment Refs support grouped focus, events, observation and measurement without changing the rendered DOM structure.
- Trusted Types support avoids coercing trusted objects back into strings before browser validation.
