- ltlmix is a new tool that generate formulas by combining existing
ones. See https://spot.lre.epita.fr/ltlmix.html for examples.
- ltlfilt learned a --relabel=io mode, that is useful to shorten
atomic propositions in the context of LTL synthesis. For instance
% ltlfilt -f 'G(req->Fack)&G(go->Fgrant)' --relabel=io --ins=req,go
G(i1 -> Fo0) & G(i0 -> Fo1)
The resulting formulas are now usable by ltlsynt without having to
specify which atomic propositions are input or output, as this can
be inferred from their name.
- autfilt learned --restrict-dead-end-edges, to restricts labels of
edges leading to dead-ends. See the description of
restrict_dead_end_edges_here() below.
