+## Breaking Changes
+
+### Separate hydration exports have been removed
+
+With version [3.22.0](https://github.com/tannerlinsley/react-query/releases/tag/v3.22.0), hydration utilities moved into the react-query core. With v3, you could still use the old exports from `react-query/hydration`, but these exports have been removed with v4.

+- import { dehydrate, hydrate, useHydrate, Hydrate } from 'react-query/hydration'
++ import { dehydrate, hydrate, useHydrate, Hydrate } from 'react-query'
