This week: cleaned up completed feature flags, fixed DevTools navigation handling, improved error revival in Flight, and strengthened type checking for capability flags.
This week in React: We cleaned up several experimental feature flags after completing their rollouts, reducing technical debt. We fixed an issue where React DevTools would remount unnecessarily on same-document navigations in Chrome 153. We improved error serialization in the Flight protocol and strengthened type checking for host config capability flags to eliminate false warnings.
