Is there even a changelog for the new version?
As for content, it should be noted that there's some stuff even in the old version that doesn't show up in the gallery. Most notably, in-combat rape-stuff.
For example, at tier 2 fallen, or whatever it's called, what's her face can get raped by those fish people in that one non-repeatable quest, and she can even end up pregnant from it.
If the dev added more in-combat scenes, they won't show up in the gallery most likely. I imagine they'll be added eventually, but until then, you're shit out of luck if you complete certain quests and don't make saves in the proper areas... and on multiple levels of Fallen as well.
