- Fixed calculation of conditional credal set.
- Added SetFunction.get_choquet to calculate the Choquet integral (contributed by Erik Quaeghebeur).
- Added __radd__, __rmul__, and __rsub__ for Gamble (contributed by Erik Quaeghebeur).
- Event.__sub__ now only does set difference with a collections.Set (so Event minus Gamble will be a Gamble via Gamble.__radd__, but Event minus Event is an Event).
- Event.__init__ now raises a ValueError when creating an event with elements that are not in the possibility space, instead of silently omitting them (fixes issue #3, reported by Erik Quaeghebeur).
- LowProb.extend now has default upper=False argument, as it would raise a ValueError instead.
- New LowPrev.get_extend_domain method which calculates the maximal domain to which the lower prevision can extend. This is now used if keys are not specified (or are None) when calling LowPrev.extend (addresses in part issue #4, reported by Erik Quaeghebeur).
- Prob.extend now has a 'linear' algorithm to spread remaining mass over undefined singletons uniformly (addresses in part issue #4, reported by Erik Quaeghebeur).
- Improved Choquet integral calculation so level sets are constructed at the same time that the values are ordered.
- Added SetFunction.get_bba_choquet method to calculate Choquet integral of a basic belief assignment.
- First release.
