I enjoyed the update.
The amount of new content is acceptable. It's certainly not a 2-3 months worth of update like some people claim, it's more like 8 months. I was honestly expecting much less considering how much of a shitshow the last year has been.
The new sandbox scenes certainly gives the sandbox structure a purpose. Some of them don't align with your quest progression, but that much is expected.

They are not in the gallery, go to her house at night.
There are minor revamps to old quests. There are shit ton of new scenes in the sandbox part. People who say there is nothing new are only looking at the gallery. Sandbox scenes aren't on the gallery.
