MINOR A cart.updated event is now emitted whenever any tax-related operation occurs on the cart, such as adding, updating, deleting, or performing bulk actions on tax items. For more information, see Observable Events.
MINOR We have now introduced a new optional field, order_number, which serves as an alternative to the existing order_id. For Authorize.net transactions, order_number will be sent instead of the order_id, and will appear as the invoice number. For more information, see Update an Order.
