This is the second release of PM Gnu Chess 4.0.
This release fixed the following bugs:
    1. Pawn promotion
       Now you can promote your pawn to queen.
       Promotion to other pieces is not working yet. The chess engine
       of this version only does this much.
    2. Some message events
       When game is ended the proper message box pops up instead of 
       doing nothing in the early release.
    3. Color settings now are saved for next time.
    4. Fixed/changed "new" game command
       The "new" command used to cause some problems. Hopefully this is fixed.
       Some improvements:
       a. If white is on the top, "new" command assumes the
          player wants to play as black and it immediately makes move as white;
       b. You can issue "new" game command any time now.
       c. "new" game will not reset deep thinking to default (disable) now.

Known bug:
      Occasionally Computer make a quick move and claim "computer will soon mate"
      This problem is only found in the deep thinking mode. Take back the move and
      let computer make move again. Do followings: 
          1. Ctrl+S, Stop computer thinking.
          2. Ctrl+R, Take back move
          3. make move,
          4. Ctrl+D, Set Deep thinking agian.
 
I am not sure what causes the problem yet.
Send bug report to yfan@alchemy.chem.utoronto.ca.

Have fun!
