Summary
React's
browser()API, used by thepathlessSSROutletDeferralfeature, was previously documented as React Canary–only. It shipped stable in React 19.3, so this PR aligns docs, code comments, and the example app accordingly.pathlessSSROutletDeferralruntime error message and doc comments (browserBailout.ts,Router/index.tsx, bailout tests) now say "React 19.3 or later" instead of "currently React Canary".RouterFeaturesentry in the components API reference now describebrowser()as stable since React 19.3.react/react-dommoved from the pinned19.3.0-canary-eb8feb71-20260814build to stable^19.3.0; the lockfile is regenerated and free of canary entries.Not touched: the
