To enhance the customer experience, we have introduced a new feature in the Checkout API. The addition of the useIndividualShippingEstimates variable allows for displaying precise shipping estimates for each item in the customer's cart. This feature populates the shippingEstimateDate with a specific delivery date, such as "2023-07-12T14:52:00+00:00", instead of just providing an estimate in business days.

For detailed instructions on implementing this feature, please refer to the Displaying SLA by item in Checkout guide.
