Never. Or at least, there's as much a chance of Carrara6 being released first. I got confirmation from an Eovia tech on both the vanishing group names and the distorted UV maps issues. They have been "sent in," but they may not make the next patch. On other matters, after several emails he was able to clarify how the new selection tools are supposed to work, and how the fresnel term is applied and the underlying principle behind it. If anyone actually cares, I'll post what I've learned about those. They actually make a fair amount of sense once one gets over the less-than-transparent implementation.
