Signals Notebook: What does "Purged" status mean

The Purged status appears on the History section of an entity or in the Audit trail in your Signals Notebook tenant.  

When a entity is Purged, it means that the Trashed item was permanently deleted from your Signals Notebook tenant and cannot be restored.

You can activate this feature on System configuration >> System Settings >> Deletion. Click on Permanent Deletion and save the changes.
