I think you're a bit confused...
0.3.0 version is the public version right now.
We are in the early access period of version 0.4.0 which includes 3 new main quests with a lot of main plot and two new main girls.
On the 18th will be the public version 0.4.0.
I'm currently already working on 0.5.0 which will include only main girls content (trust levels).
