-# _Commodity Product - Delivery for Commodity Options and Forwards_
-
-_Background_
-
-Commodity Forwards and Options which are not swaptions do not use any `commodityPayout` but just `forwardPayout` or `optionPayout` with a commodity underlier instead. As commodity products, these forwards and options do also require access to the delivery structures, which have been confined to the `CommodityPayout` so far. This release adds the necessary delivery structures for `ForwardPayout` and `OptionPayout`.
+# *Product Model - FpML Synonym Mappings for UPI*
 
 _What is being released?_
 
-- Support for commodity delivery for commodity forwards and options.
-- Renamed delivery structures to make them generic as opposed to commodity-specific.
+This release extends the FpML mapping coverage for the enum `ProductIdTypeEnum` to support UPIs.
 
-_Data types_
-
-- Type `CommoditySchedule` renamed `CalculationSchedule`.
-- Type `CommodityScheduleDeliveryPeriods` renamed `CalculationScheduleDeliveryPeriods`.
-- Type `CommodityDeliveryInformation` renamed `AssetDeliveryInformation`.
-- Type `CommodityDeliveryPeriods` renamed `AssetDeliveryPeriods`.
-- Type `CommodityDeliveryProfile` renamed `AssetDeliveryProfile`.
-- Type `CommodityDeliveryProfileBlock` renamed `AssetDeliveryProfileBlock`.
-- Added attribute `delivery` of type `AssetDeliveryInformation` to type `OptionPayout`.
-- Added attribute `delivery` of type `AssetDeliveryInformation` to type `ForwardPayout`.
-- Added attribute `schedule` of type `CalculationSchedule` to type `ForwardPayout`.
-- Added conditions `DeliveryCapacity` and `PriceTimeIntervalQuantity` to type `OptionPayout`.
-- Added conditions `DeliveryCapacity` and `PriceTimeIntervalQuantity` to type `ForwardPayout`.
+- The `ProductIdentifierSourceMappingProcessor` has been updated to map FpML productIdScheme http://www.fpml.org/coding-scheme/external/iso4914 to `ProductIdTypeEnum->UPI`.
