# Migrating from `@shopify/react-html@8.x` to `@shopify/react-html@9.x`

Version 9.x of `@shopify/react-html` brings tight integration with `@shopify/react-hydrate`.

## `HeadUpdater` is now `HtmlUpdater`

This component was renamed because it now also renders a `HydrationTracker` from `@shopify/react-html`.

```diff
import {
-  HeadUpdater,
+  HtmlUpdater,
} from '@shopify/react-html';

- <HeadUpdater />
+ <HtmlUpdater />
``
```
