Hi to you too!
1) Yes, the v1.05 update is for the Dad(and mainly Daughter centric) path. (Sorry you are not interested in it, because the Dad path is a lot better. especially since the Dad for all his flaws tries to correct his mistakes and the son, if you play both paths you will see it clearly, is turning out to be psychotic. A situation that is not only existing because of mistakes made raising him)
2) The new "game", Dual Family Part Two, is only telling the story of the Son path. But and many others here can tell you too, Part Two of DF is anything but a game. It is your choice if you see it as artsy, trolling or a drug-induced fever dream.
