# \[Developer Preview] Cart Transform API - Updating lines in the cart

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](https://shopify.dev/docs/api/functions/reference/cart-transform/developer-preview).
