Previously, the Cart Transform API enabled functions to
expand a single cart line item to form a bundle of components or add-on products, or
merge multiple cart lines into a single line that represents a bundle.
With this release,
update operations will also allow you to override the price, title, and/or image of a given line item. This gives you more more flexibility to make additional customizations to items in the cart.
More information can be found in the Cart Transform API developer preview documentation.
