You can now set a price mode on a CustomLineItem that controls whether Cart Discounts should be applied to them by Composable Commerce or not. Use this if you want to control application of Cart Discounts for each Custom Line Item in the Cart individually. For backwards compatibility, Standard is the default price mode for newly created Custom Line Items, that allows application of Cart Discounts. For cases where Cart Discounts should not be considered on a Custom Line Item, you can change its price mode to External via new update action. You can still overwrite the price for a Custom Line Item via Change CustomLineItem Money update action.
