The History tab at the item level displays what changes were captured during edits. Use the Before and After columns to compare the data with the previous version and three new collapsible sections. A Revert button is in the top right of the screen. Summary 'pills' are also displayed on each version tab for quick identification of which areas of the item have been updated.
When expanded, the top Item section displays the item preview, the middle ‘Properties’ section displays Status and Scoring Status changes, and the third section shows the Source code changes. Source code highlighting has also been improved to highlight all changes in the QTI.
