     This is the first production release.

     Major changes since version 0.3:

      1. A cooling-off period is now enforced for the bus diverter coil.
         This was to help prevent the coil from overheating.

      2. PAYBACK TIME was removed from the time machine feature. The
         scoring was out of balance with the rest of the game.

      3. Crane error detection was implemented.

      4. Overall, the scores on the game were reduced by half.

      5. Several sound and display timing issues were cleaned up.
