The OEOmega constructor will now initialize all
data members appropriately to avoid subtle unreproducible errors
based on random values in memory.
Calling SetWarts with true had been broken until the 2014.Oct
release. The output conformers would have the numeric index(wart) in the
.oeb format but not the .sdf format. This is now fixed. The default
behavior of OETautomerOptions has been changed from true to false
when applying a numeric index(wart) to titles.
