Shopify Release notes and new features

Delivery options in Shopify Functions input now expose their metafields

Shopify Functions can now read metafields attached to delivery options in the cart. On API version 2026-10 , you can call metafield(namespace:, key:) on any option in cart.deliveryGroups.deliveryOptions . This affects apps that build Delivery Customization Functions and any other function whose input includes delivery options. No action is required.
