@ -18,6 +18,13 @@ New in spot 2.5.0.dev (not yet released)
as Fin(0)|(Fin(1)&Inf(2)) instead. Likewise for
is_generalized_streett
- the conversion from Rabin to Büchi was broken on Rabin-like
acceptance condition where one pair used Fin(x) and another pair
used Inf(x) with the same x. Unfortunately, this situation could
also occur as a side effect of simplifying the acceptance
condition (by merging identical set) prior to running the
conversion to Büchi.
