Change Sets allow Elastic Path users to create groups of business objects (products, catalogs, promotions, etc.). These groups can be locked to prevent editing and then moved to another Elastic Path instance using the Overview, at which time they can then be "released" to allow editing again. This is typically used as part of a staging to production workflow, where changes made in the staging environment need to be carefully managed before being moved into the production environment.

The Change Set services can be used to manipulate Change Sets, their members, and their assigned users.
