July 2025 — TanStack/query monthly summary: Implemented a critical type-safety enhancement for HydrationBoundary to bolster hydration reliability and catch type-related bugs earlier in the development cycle. The fix enforces that HydrationBoundary.state is required and must be a DehydratedState or nullish, reducing runtime errors during SSR hydration and clarifying the API contract for consumers. The change was implemented in commit e07812be21e4d19cd30fc74965a06d438b98ac71 with message 'fix(react-query): HydrationBoundary has strictly typed `state` (#9520)'.
