I was absent for quite a while, mainly for two reasons.

1. Problems in IRL 

2. I poorly planned what I wanted to add in the update and conceived too large an event, which even had to be cut down (That’s why I labeled the version as 7.5).

In this update, the entire focus is on the transformation event, but due to mounting problems and in order not to delay the update for another month, I had to shorten everything to just the prologue of this event.(Nevertheless, I managed to create 217 images and one simple animation.)

To start the event, you just need to approach Veronika's office from the south wing.

Content of this event:
Transformation into a sock (For Madeline and for Veronika)
Transformation into a toilet (For all 4 girls)
Transformation into toilet paper (For Klara, Chika, Madeline)
As well as transformation into Veronika's food and part of her body

As you correctly understood, the update content is predominantly related to the SCAT filter.
