So the way I read it, if you want to opt in, you make the new changes they state in your yml. I didn’t and just hit upgrade to pull the new images and it worked fine. I don’t see any issues, but I’ll be glad if someone says I did it wrong.
I think it’s only breaking if you pull the new yml and don’t move your data.
I don’t want to hear one damn thing about thier next game until the day of release. Over hyping was what got them into trouble last time.
