Track Changes and Control Documents with the Activity Log
Use the Activity Log to see an overview of all changes to a document in one screen. In the Activity Log, you can see:
When a document was approved
Who approved the document
When major versions of the document were saved
To access the Activity Log:
Click Activity Log.
Drill into the document timeline to see which individual pages within the document were updated and the users who made changes. This gives you a more granular look at what has changed between review or approval or between when major versions were saved.
Switch to the list view of the activity log to see a running list of changes made to the document.
Filter by Versions saved, Status changed, and Page updated to see only specific changes made to the document.
You can also click Export to CSV to store this information or share with others outside Confluence.
