- New in MacChess 5.0 Rotterdam December 1998
-
- First, a special "thank you" to Richard A. Fowell.
- He helped test MacChess 5.0 and proofread my English.
-
- Special thanks also to everyone that gave me support and advice by
- sending me postcards and email.

- ====== NEW FEATURES ======
-
- 1. Designed a new move generator with the following advances:
- - the program is 200 Kb smaller
- - now generates a legal move list, which allows it to detect forced moves -
- this allows it to find some deep mates very quickly in the normal search
-
- 2. Checks that moves obtained from the transposition are legal before using them.
- Older versions of MacChess could crash because of illegal transposition moves.
- Now it is fixed for ever.
-
- 3. Changed the size of the nodes and nodes/second variables
- from 32 bits to 64 bits. The "nodes" display in the "Info" window
- in MacChess 4.0 could overflow in as little as 3 hours.
- Now it won't overflow in five years.
-
- 4. Added a larger chess board and a optimized Classic piece set for it.
- Richard Fowell optimized his American piece set for this too. (Thanks again)
- Other piece sets are scaled when used with the larger board.
-
- 5. Added a result pop-up menu in the “Game Info” window.
- Also, automatically fills in game result in "Game Info" when known.
