- When running translators ltlcross will now display {names} when
supplied.
- autfilt learned the --partial-degeneralize option, to remove
conjunctions of Inf, or disjunction of Fin that appears in
arbitrary conditions.
- ltlfilt and autfilt learned a --nth=RANGE (a.k.a. -N) option to
select a range of their input formulas or automata (assuming a
1-based numbering).
- When running translators ltlcross will now display {names} when
supplied.
- ltlcross is now using the generic emptiness check procedure
introduced in Spot 2.7, as opposed to removing Fin acceptance
before using a classical emptiness check.
