* The new function mp_class(f) returns the class of the formula
f in the temporal hierarchy of Manna & Pnueli.
Bug fixed:
Bugs fixed:
* The minimize_wdba() function was not correctly minimizing automata
with useless SCCs. This was not an issue for the LTL translation

consequence, some tricky safety or guarantee properties were only
recognized as obligations.
* When ltlcross was running a translator taking the Spin syntax as
input (%s) it would not automatically relabel any unsupported
atomic propositions as ltldo already do.
New in spot 2.2.2 (2016-12-16)
