The former + two are enabled by default. Benchmarking has shown that the + latter one does not always have a positive effect, so it is + disabled by default. + + - The scc_filter() function, which removes dead SCCs and also + simplify acceptance conditions, has learnt how to simplify + acceptance conditions in a few tricky situations that were not + simplified previously. + + - An experimental "don't care" (direct) simulation has been + implemented. This simulations consider the acceptance + of out-of-SCC transitions as "don't care". It is not + enabled by default because it currently is very slow. + + * Command-line tools + + - ltl2tgba and ltl2tgta now honor a new --extra-options (or -x) + flag to fine-tune the algorithm used.
