A repository enabled for version control maintains an audit trail of version history. It stores multiple versions of an object as you check out, modify, and check it in. As the number of versions of an object grows, you may want to view the object version history. You may want to do this for the following reasons:
- Determine what versions are obsolete and no longer necessary to store in the repository.
- Troubleshoot changes in functionality between different versions of metadata.
