This  is  a  major  update.  Here is a  list  of  the  most  important 
  improvements.

  - I  have  implemented  the zero-width  minimax  modification  in  the 
    normal alfa-beta search, which means 10 % fewer nodes to examine.
  - The "brain" has been much improved,  which means that it now gives a 
    more accurate and stable evaluation of the positions.
  - Endgame search now 10% faster. (16000-23000 moves/sec on a TT)
  - Special  endgame  search mode where Stello can search for  a  "Win", 
    "Win/Draw" or "Max disc".  The "Win" search is 10-50 faster than the 
    "Max disc" search, and in extreme cases up to 200 times faster.
  - Stello now evaluates its commandline,  so you can drag games to  its 
    Icon,  and it will then load it,  and you can install Stello with  a 
    DOC type of "GAM",  so it will start and load a game if you click on 
    it.
  - Stello now also supports the drag & drop protocol under Multitos.
  - The  filename  is displayed in the game window so you can  see  what 
    game you have loaded.
  - Manual input of games is now completely mouse controlled.
  - GDOS and Speedo GDOS is now supported.  This means very nice  output 
    via  printer  and META file.  If you don't have GDOS you  can  still 
    print and export as ASCII.
  - Window with transcript of game.
  - Context sensitive helpfile for St-Guide.
  - various  bugfixes (It should now finally be possible to  load  games 
    and pictures on TOS 1.0 and TOS 1.2)
