- In addition to detecting stutter-invariant formulas/automata, some
can now study a stutter-sensitive automaton and detect the subset
of states that are stutter-invariant. See
https://spot.lrde.epita.fr/ipynb/stutter-inv-states.html for
examples.

- Determinization has been heavily rewritten and optimized. The algorithm has
(almost) not changed, but it runs muuuch faster now. It also features an
