These changes affect how reserved prefixes can be modified in the admin as well as how access controls are set by apps. As a reminder, by default metafields and metaobjects are owned by Shopify and provide no restrictions to reading, writing, or modifying. For app reserved prefixes, access is configurable. For example, if you set access for `admin` to be `MERCHANT_READ` and `storefront` to be `PUBLIC_READ` then the merchant will have read-only access in the Shopify admin, and the metafields will be publicly readable in the storefront surface area (Liquid templates and Storefront API). Learn more about access controls for [metafields](https://shopify.dev/docs/apps/custom-data/metafields/definitions/access-controls) and [metaobjects](https://shopify.dev/docs/apps/custom-data/metaobjects/access-controls) respectively on [Shopify.dev](https://shopify.dev/docs/apps/custom-data/).
