Change Log

Version 5.0 introduced March 4 2004
	New file system organization. 

	Updated Exhibit batch files to correspond with new file system organization. Kiosk
	desktops should be updated with the new files. 

	Version number is now recorded in the log files. Log files for the Exhibit
	program now include the word exhibit in the file name.

        Fixed bug introduced in version 4.3 in which motion events were consumed in 
        MissionCentral and MissionCentral would always timeout when the time had 
        expired regardless of mouse motion. Also added functionality so that clicks
        and motion over the panorama and map will reach the timeout motion listener
        and prevent timeouts.

        Panorama test windows are now disposed of when closed by the user so that
        memory can be reclaimed.

Version 4.4 introduced February 4 2004
	Fixed update issue which caused the rover's actions to lag behind the
	rover status displayed on screen.

	Fixed bug in Calibration software that caused incorrect values to be displayed
	when loading a calibration file from a rover on which the tilt servo's range
	had been changed. Calibration will now work correctly for old and new tilt servos.

	Removed unused GUI files.

Version 4.3 introduced January 16 2004
	PER4.3 introduces a popup menu triggered by a right click in Mission
	Central. The four menu choices are "Navigate and find rock", "Navigate
	only", "Turn only", and "Take new panorama." Selecting one of these options
	will skip the final countdown and go directly back to taking a new
	panorama. The mission clock continues to run until a mission is completed
	through the Go button (or a timeout).

Version 4.2b introduced January 13 2004
	The panorama tilt angle is now adjustable on the expert tab of the Exhibit

	Also fixed a bug. If there was an obstacle during approach rock, it used to think it was
	an error and now assumes it is the rock.

	Also, this updates rover firmware to Cereb12 for cerebellum and Exhibit11 for Stayton.
	The latter slows down drive motors to 80%PWM so that at stall the gears don't break.
	The former slows down servo motion (steering and tilt) significantly and remembers
	previously commanded position, to reduce force and wear on the tilt servo in particular.
