# New `selected_delivery_option` field in cart

We have added the `selected_delivery_option` as part of the `CartDeliveryGroup` as well as the `handle` field as part of the `CartDeliveryOption` in the cart.

The `selected_delivery_option` field represents the selected delivery option in a delivery group. The `handle` field represents a unique identifier for the delivery option.

A default `CartDeliveryOption` is saved as the `selected_delivery_option` in each `CartDeliveryGroup` available.

We also added the `cartSelectedDeliveryOptionsUpdate` mutation, allowing you to update the `selected_delivery_option`s of each of your delivery groups.
