- a new setting for "Default digit entry mode" ("Digit fist" vs. "Cell first")- undo / redo now works for pencil marks as well as numbers.- a new "Auto pencil" setting for erasing / adding pensil marks automatically as cells are solved / cleared.- a new setting for highlighting cells that contain the selected digit.- a new menu option: "Auto-fill" will fill out the pencil marks in all the empty cells (using this option counts as using helper, since it may, inadvertently, reveal parts of the solution).- now there is a way to reset high scores / history (see Settings->Reset all scores).
