History

The history of an object shows all existing versions of the object and the relationships between the versions. The term history refers to all the object versions created before the current object version (called predecessors). History refers to all the object versions created after the current object version (called successors).

The figure shows the history of the file save.c. The arrows indicate which version was checked out from which; for example, version 2 was checked out from version 1. Version 1 is a predecessor of version 2, while versions 3 and 2.1.1 are successors of version 2. Versions 3 and 2.1.1 are parallel versions.
