In the new update, there are only minor gameplay changes. There is no new content, maybe some new Karina's lecture.
Three new rooms/halls and gym clothes are added at the university.
About the quest system, above the phone, you can now see quests currently active for that day, and when you complete it, it is removed/marked as done.
The gameplay changes are nice to have.
The author probably wants to create an environment before continuing on new content. That is my opinion, and currently, it is much easier to do now, when there isn't a lot of content, than later, when it is more complex to make any changes.
