PWA Kit and Managed Runtime

PWA Kit

- Storefront Preview Integration with a Third-Party CMS
    - Use a third-party content management system (CMS) with Storefront Preview. For example, if you have a holiday sale banner managed by your CMS, use Storefront Preview to see how the banner will appear on your site during your specified time period. See Storefront Preview.

- Validate Customer-specific Site Changes
    - Preview how your Progressive Web App (PWA) Kit site will look based on one or more customer group IDs. For example, preview your site as it would appear to shoppers who get an employee discount. See Preview Your Storefront.

Managed Runtime

- Node 20 Support
    - Projects can now deploy with [Node 20!](https://nodejs.org/en/blog/announcements/v20-release-announce) PWA Kit projects will need to upgrade to the latest 3.4.x version and follow the instructions in [Upgrade Node Version](http://review-app-sdb2c-com-pr-1078.herokuapp.com/docs/commerce/pwa-kit-managed-runtime/guide/upgrade-node-version.html).

- Osaka Region
    - Customers in Japan can now run their environment in the Osaka region, in addition to the existing Tokyo region. Your region can be changed via Environment Settings.

- Source Maps for Debugging
    - Source maps are now available in Managed Runtime. This feature is designed to greatly improve the development and debugging experience by enhancing error stack readability. Source Maps can be generated starting in PWA Kit 3.4.x, and can be enabled by toggling the enable\_source\_maps environment setting. See [Debug Using Source Maps](https://review-app-sdb2c-com-pr-1036.herokuapp.com/docs/commerce/pwa-kit-managed-runtime/guide/debugging.html#debug-using-source-maps).
