Change Tracking
This leads to a refinement of the term 'change tracking' to two variants:
Edit Tracking
'Edit tracking' is the ability to record edits made in an editing application in order that they can be viewed, accepted or rejected at a later date.
Revision Tracking
'Revision tracking' is the ability to record changes to a document such that these changes can be displayed in a document viewer, and the document rolled back to a previous version.
