@ -113,6 +113,12 @@ New in spot 2.4.1.dev (not yet released)
can be passed to disable this behavior (or use -x degen-remscc=0
from the command-line).
- 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.

(These functions still work but compilers emit warnings.)
