Announces React 16 with Fiber that moves scheduling from speed to cooperative multitasking so large renders yield to higher‑priority work; adds fragments and strings as return types, portals, error boundaries plus automatic unmount on render errors, and opt‑in async rendering per subtree. Describes offscreen (very low) priority for hidden content, commit‑phase pre rendering to improve code‑splitting, and notes the same alpha is already running 100% on facebook.com and messenger.com while experiments continue.
