Platform Release 27 May 2019

Added the key attribute to CartDiscount. You can use the key attribute when creating or updating a CartDiscount.

Introduced the following changes to the GraphQL schema (in SDL format):

extend type CartDiscount {
  key: String
}

extend input CartDiscountDraft {
  key: String
}

extend input CartDiscountUpdateAction {
  setKey: SetCartDiscountKey
}

input SetCartDiscountKey {
  key: String
}
