Version 3.80 has been restructured mainly for the purposes of making it easier to create C# projects and making it easier to modify the existing controls. The side effect of this restructuring is that upgrading pre-3.80 projects to 3.80 or higher is not an easy upgrade.
The AdvancedHMIDrivers project has not changed significantly, so I'm not sure how easy it is to take 3.80 driver project into an older Solution.
