+## React 18 - New Suspense SSR Architecture
+
+We're happy to announce support for the new React 18 server architecture during build time.
+When installing `react@alpha` and `react-dom@alpha`, you automatically opt into the new
+[`pipeToNodeWritable`](https://github.com/reactwg/react-18/discussions/37) renderer.
+Now you're able to use `Suspense` and `React.lazy` on the server as well.
+
+## Shopify app for Gatsby Cloud
+
+Following the brand-new Shopify source plugin published in the [previous release](/docs/reference/release-notes/v3.8/#gatsby-source-shopify-v5),
+this release brings Gatsby Cloud to Shopify App Store.
+
+Install Gatsby Cloud from the app store to quickly connect your Shopify store. Choose an existing project you’ve
+been working on or get up and running the Shopify starter in seconds.
