Version 5 (October 2023) removed the array based overloads, so useQuery takes a single object with queryKey and queryFn. cacheTime is now gcTime, which describes what it does: how long an inactive query is kept before garbage collection.

The status names changed too. The old isLoading, meaning there is no data yet, is now isPending. isLoading now means pending and fetching, which is the flag most spinners actually want. isInitialLoading is gone. keepPreviousData is replaced by placeholderData set to the exported keepPreviousData function.

The migration guide ships codemods for the mechanical renames. Version 5 also requires TypeScript 4.7 or later and React 18 or later for the React adapter, so the upgrade may pull those with it.
