 ## Upgrading to Volto 18.x.x
 
+### Volto runs now on React 18.2.0
+
+We have updated Volto to use React 18.
+This has been the latest published stable version since June 2022.
+This aligns Volto with the latests developments in the React ecosystem and opens the door to up to date software and React features, like client side `Suspense` and others:
+
+- Concurrent rendering in client (Suspense)
+- Automatic batching updates
+- Transitions
+- New hooks `useId`, `useTransition`, `useDeferredValue`, `useSyncExternalStore`, and other hooks
+
+### `react-portal` dependency removed
+
+`react-portal` is deprecated and it was removed from Volto.
+The Volto code that relied on it was mainly CMS UI components.
+If your project relies on it, either in your code or the shadowed components you may have, you should update to use the standard React API, `createPortal`.
+You can update your shadows taking the modified components as templates.
+As a last resort, you can install `react-portal` as a dependency of your project.
+However, this is discouraged, because the React 18 rendering could have unexpected side effects.
+It is recommended that you use the React API instead.
+
 ### ESlint project configuration update
 
 `@plone/registry` and [other packages on which Volto depends](https://github.com/plone/volto/tree/main/packages) are now stand-alone releases in the monorepo structure released in 18.0.0-alpha.4.
