 ## History
+**v1.10b: 22th April 2014 by JP Liew**
+* changed SS, RESET, DC pins to use weak internal pull-up resistors
+
 **v1.09b: 17th April 2014 by JP Liew**
 * changed verticalFlip() to flipVertical() and horizontalFlip() to flipHorizontal() for consistency
 * added debug messages for doCmd()
