Mar 1, 2026

Delivered API reliability and clarity improvements for TanStack/query in March 2026. Key features include expanded tests ensuring query functions return values (covering useQuery family and related APIs) and comprehensive tests for prefetch and data handling helpers. Documentation updates clarified staleTime semantics for static vs Infinity and their effects on invalidation and refetch behavior. These efforts reduce regression risk, improve developer confidence, and provide clearer guidance for users integrating TanStack/query with eslint-plugin-query.
