tanstack_query 1.2.6

Widgets that help state management of asynchronous operations such as sending HTTP requests, getting the response, and caching the result.

1.2.6 (15/04/26)

• Fix: Garbage collection bug where active Query could be evicted after invalidateQueries() or clear() — mirrors React's GC lifecycle exactly.
• Arch: QueryObserver mirrors React's GC lifecycle exactly by rebuilding the underlying Query reference after cache invalidation.
• Arch: Rework useInfiniteQuery internals to mirror React's architecture exactly — extract InfiniteQueryBehavior (port of infiniteQueryBehavior.ts), rewrite InfiniteQueryObserver (port of InfiniteQueryObserver.ts), and hook behavior into Query.fetch() for React-parity dedup, direction tracking, and page management.
• Fix: isFetchingNextPage incorrectly true on remount after fetchNextPage.
• Fix: Rapid fetchNextPage calls no longer cause stuck isFetchingNextPage state.
• Fix: Mismatched generic cache entries (e.g. InfiniteQueryResult<Object> for a useInfiniteQuery<int>) are now safely detected and discarded, triggering a fresh fetch.

1.2.5 (23/01/26)

• Fix: Prevent infinite widget rebuilds when passing inline (non-const) mutationKey to useMutation.
