This change wont have much effect on existing software users, but is designed more for new users.
When the software is first installed, it comes with sample data so you can see how it gets used. Some people are not sure how to remove the sample data. So now it is made easier. A new menu option has been added called 'Delete Sample Data'. Also when someone enters a license key, it automatically prompts to see if they want to remove the sample data in the database. This only applies if the sample data has not been already deleted.
