Brush Modifications
From ZBrush Info
Some brushes have a new behavior or several new behaviors and some existing brushes have been updated. This is the list of the main additions and modifications.
Brush Stroke Length : The stroke length of your brush has been increased 16 times more than ZBrush 3.1. Now your stroke can be continued for a very long period before stopping on your mesh.
Note: To revert to the original behavior of the ZBrush 3.1 brushes, Go in the Brush >> Depth menu and deactivate the Fast Sample mode
