What was the one enum that changed?

Just expand the Enum field down, click on the file and the difference is shown:

And I find that we added two new reports: reportUnintializedItems and reportUnusedItemsAll.  These are part of an effort we have with a specific customer to add DO178B qualified reports to Understand 2.0.  The first reports any variables that are not initialized when defined.  The second reports any unused items (this expands and will eventually replace our existing reports of just unused functions and object).
