List of Changes in Houdini 5.01
Corrections
- The Chess960 castling codes are now correctly handled. As a bonus, the Chess960 support is now compatible with Arena which uses the non-standard O-O and O-O-O as Chess960 castling moves.
- Houdini 5 Pro: Setting the thread affinities now also works on Windows 7 and Windows Server 2008.
Improved compatibility with GUIs
- Work-around for some GUI's not showing engine output at depth 1: Houdini now generates a line with depth 99 in table base positions.
- The behavior of the MultiPV_cp parameter ("Delta") in Aquarium is reverted to what it was in Houdini 4, which seems more intuitive to Aquarium users.
Changes to UCI Options requested by users
- For the "Contempt" option the minimum value has been changed from 0 to -10.
- A new "Move Overhead" option for users playing engine games in which the move transmission has a time lag; the option specifies the extra time needed for each move in milliseconds.
- The new "UCI Log File" parameter, when set, will produce a log file of all the UCI communication of the engine.
