Abstract: A method, system, and computer usable program product for creating a superseding software product release are provided in the illustrative embodiments. A first set of metadata describing a set of parts related to a first release is received at an application executing in a computer. A second set of metadata describing a second set of parts related to a second release is received. Using the first and the second sets of metadata, a part to be added to the second set of metadata is identified such that the second release is sufficient to supersede the first release. The second set of metadata is updated to include metadata of the part such that an updated second release according to the updated second set of metadata is sufficient to supersede the first release.
