Today's Highlight

🔥 TkDodo's React.use migration in TanStack Query — The PR switching from throwing promises to React.use is the standout activity today. This represents a fundamental shift in how TanStack Query handles suspense, moving away from the "throw a promise" hack that React Suspense originally relied on, toward the official React.use API. This change signals that the React ecosystem is maturing past its early Suspense patterns and embracing the stable APIs. Keep an eye on this one — it will affect every TanStack Query user running suspense mode.

Also noteworthy: the ViewTransition iOS Safari crash (#35336) drew attention from both Dan Abramov and Sebastian Markbåge, suggesting React's new View Transitions feature has a critical platform compatibility issue that needs resolution before wider adoption.
