# POS UI Extensions 1.7 Update: Support for multiple cart discounts

As of March 13, we added the following updates to POS UI Extensions:

* Added a `discounts` property to the Cart object, which includes all cart discounts.
* Added `addCartCodeDiscount` to the Cart API, which allows the UI extension to add a code discount. The existing `applyCartDiscount` will still function for code discounts, too.
* Added `remove AllDiscounts` to the Cart API, which allows the UI extension to remove all cart discounts.
* Added a `listHeaderComponent` to the List component.

All of the changes are available for POS UI extensions version 1.7.0 and POS app version 9.4.0. See the [version log](https://shopify.dev/docs/api/pos-extensions/ui-extensions-reference/versions) for all version details.
