Not really. You still have to do a some work to make use of PWA features. This release just integrates the sw-precache-webpack-plugin into the build system so it's easier to add a ServiceWorker to your app should you decide to do so. Here's the documentation: https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#making-a-progressive-web-app https://github.com/facebookincubator/create-react-app/blob/m... Also, ServiceWorkers are not just useful on mobile! Applications targeting desktop browsers benefit from them just as much, especially if you're thinking offline-first.
