About this task

Each revision on the Revision History page is a snapshot of the object at that time. You can preview the content of each revision and compare it to other revisions. You can use this to see how an object changed between revisions.

For example, if you compare revisions of a topic, you can see the content of the topic at each revision. And you can see the highlighted differences in content between the revisions.

You can also compare different revisions of one topic with all the revisions for a clone or another instance of the topic.
