Ability to check if a dish in a specific size is available for sale

Starting from V9Preview3, it became possible to check the inclusion of a dish in the menu in the specified size: GetIncludedInMenu. However, before calling, you need to ensure that the dish is not deleted: IProduct.IsActive is true.

Previously, the API already had the ability to get a list of sections where the product is available for sale in at least one size: GetIncludedInMenuSectionsByProduct, as well as the ability to call to get the price from the order: GetPrice.
