Store-specific Cart Discounts achieved general availability status

After collecting feedback during the beta phase, we have moved Store-specific Cart Discounts out of beta. The status of the following features has been changed to general availability:

• manage_cart_discounts:{projectKey}:{storeKey} and view_cart_discounts:{projectKey}:{storeKey} scopes
• stores field on CartDiscount and CartDiscountDraft
• Get, Query, Check, Create, Update, and Delete CartDiscount in Store endpoints
• Add Store, Remove Store, and Set Stores update actions on the Cart Discounts API
• StoreCartDiscountsLimitReached and MaxStoreReferencesReached errors

This feature lets you build Cart Discounts specific to a Store to model, for example, customer-specific or brand-specific cart discounts. To know more about Cart Discounts, see the Cart Discounts API.
