About the new permission "SuperUser":
This permission is now requested to make Total Commander work better on rooted devices. It tells the SuperUser app that Total Commander supports root functions. It has no effect if your device is not rooted. Root functions allow Total Commander to write to system folders like /system or /data. You will be warned before anything is written if the partition is write protected.
