 4. CHANGES IN VERSION 1.1
 
 - fixing a bug in the way sets were used for strongly connected components. Thanks to Joachim Klein (klein@tcs.inf.tu-dresden.de) who found the bug and proposed a patch to fix it.
-- fixing a bug in the simplification with strongly connected components for the generalized Büchi automaton. 
-- improving the simplification with strongly connected components for the generalized Büchi automaton.

 - using getrusage to compute running times for the statistics
 - some other minor updates.
