This release still feels like a second service release for the PP2014 .5 Upgrade aka Poser 11.
Right now everything seems to be about to make the Poser renderer a more complete cycles renderer, which would be nice, if there were other benefits.

Right now, I could just get cycles for free with Blender.
I miss a hair room upgrade. More realistic looking hair, faster calculations.
Same for clothes. 
What has been done, to work against the skating effect in figure animations?
