Set Option: Model object attribute.
Specifies that release scoring be used to select object versions whose release best matches the project's release. Release scoring is not used by default for task-based update, but may be considered if you develop parallel releases and one release includes the other release's changes. As there are definite caveats to using this option, it should be used only after serious consideration.
