This one is only a small update, you'll notice your house has changed. You'll find Sophia on the couch/sofa and you'll be able to do stuff there and there's a new scene with Beatrice. You can also get keys now for a few more scenes. Hint: you need to do alot of detective work on your PC.
This update is probably just to let people know they are still working on it but it needs a little bit longer. So its just a taster. Hence its .6.10 rather than .7
There isn't any new quests or extension to quests in this update.
Though i dont think its much more of a wait for .7, so all the new/extensions to quests will be then.
