Changes to diagrams between sessions are displayed in the Diagram Change Highlighting window:

The upper pane of the window displays each sheet of the diagram on a separate tab, on which diagram name and sheet name is displayed.

Each tab is divided into left and right sections. The left section displays the sheet as it was at the selected target session. The right section displays the sheet as it was at the selected base session.
The diagrams can be zoomed into and changes highlighted using toolbar icons as described below.

Use the up, down and sideways arrow keys and the mouse wheel to move around a diagram.
If the window was opened using the Highlight Changes > Latest option the target session is the current session and the base session is the previous session.
Details of the target and base sessions are displayed at the bottom of each pane.
The lower pane lists the changes on the currently selected sheet.
