+### new API for `useQueries`
+
+The `useQueries` hook now accepts an object with a `queries` prop as its input. The value of the `queries` prop is an array of queries (this array is identical to what was passed into `useQueries` in v3).
+
+```diff
+- useQueries([{ queryKey1, queryFn1, options1 }, { queryKey2, queryFn2, options2 }])
++ useQueries({ queries: [{ queryKey1, queryFn1, options1 }, { queryKey2, queryFn2, options2 }] })
+```
+

 ### Removed undocumented methods from the `queryClient`
 
 The methods `cancelMutatations` and `executeMutation` were undocumented and unused internally, so we removed them. Since they were just wrappers around methods available on the `mutationCache`, you can still use the functionality.

 If the number of queries you need to execute is changing from render to render, you cannot use manual querying since that would violate the rules of hooks. Instead, React Query provides a `useQueries` hook, which you can use to dynamically execute as many queries in parallel as you'd like.
