Okay so I did a full playthru (this game is fairly short)
A few new bugs that are minor like none of the suits or bras show anymore on model, new ancestory option if you want green skin or anything no gameplay effect but at least all the none story CG's now display it. A new Black Xeno master was added with new TF options even if they don't display outside of those cutscenes and don't seem to do anything?
Other then that nothing new really.
The tits seem to stay on model after words.
I was wrong, as of this latest update you can grow tits, sadly only in 1 cut scene, they seem to stay on model after words.
