Metafields now available on Orders, Collections and Customers
You can now add metafield definitions to Orders, Collections and Customers directly from your Shopify admin. Previously, this was only available on Products and Variants.
Metafields allow you to attach unique pieces of information to all parts of your store, which allow you to store and display information efficiently.
For an example, you can add your customers' birthdates or loyalty status in Customers, or order delivery date or packaging status in Orders.
