Hi all,
I've just put a new version of Kiwi at:

This version contains many bug fixes in the evaluation code and some tweakings in the search parameters that should help the engine search a little deeper, but with a greater risk of missing something important... oh well, nothing comes free and the best way to find out is just to put the bird in the arena and let him play!
