@ -54,6 +54,11 @@ New in spot 2.3.4.dev (not yet released)
the second command outputs an automaton with states that show
references to the first one.
- A new named property for automata called "simulated-states" can be
used to record the origin of a state through simulation. The
behavior is similar to "original-states" above. Determinization
takes advantage of this in its pretty print.
- The new function spot::acc_cond::is_streett_like() checks whether
an acceptance condition is conjunction of disjunctive clauses
containing at most one Inf and at most one Fin. It builds a
