- spot::product() and spot::product_or() learned to produce an
automaton with a simpler acceptance condition if one of the
argument is a weak automaton. In this case the resulting
acceptance condition is (usually) that of the other argument.
- gf_guarantee_to_ba() is a specialized construction for translating
formulas of the form GF(guarantee) to BA or DBA, and

- spot::product_susp() and spot::product_or_susp() are new
functions for building products between an automaton A and
a "suspendable" automaton B. They are also optimized for
the case that A is weak.
- print_dot(), used to print automata in GraphViz's format,
underwent several changes:
