Hey great! Will this new release be based on Fruit somehow (I heard 
rumors about this)?

Meanwhile until this new version materializes it might be useful to 
direct people
also to this version of GnuChess 5.07:

http://alpha.uhasselt.be/Research/Algebra/Toga/gnuchess-release/

It fixes the known bugs in GnuChess, has new features (e.g. UCI support 
and Polyglot book support)
and is also stronger. E.g. at the CCRL it has rating 2682. See
