I've seen at least two questions on ROS Answers regarding issues with following the joystick tutorials and having MD5SUM mismatches because the tutorials (and code that is automatically being displayed on the wiki) refer to joy::Joy, which was moved to sensor_msgs::Joy.
Example question on ROS Answers: http://answers.ros.org/question/3353/learning_joy
The joystick driver tutorials (http://www.ros.org/wiki/joystick_drivers_tutorials) need to be updated to reflect the migration of joy::Joy to sensor_msgs::Joy, since the joy_node has been updated to publish sensor_msgs::Joy and not joy::Joy.
