Yeah, I don't really know how version numbers work. I thought I knew, but then literally everyone just kinda goes with whatever they want with no defined system lol.
I've found that going off of the 0.9 -> 1.0 rule tends to be pretty accurate depending on how much content's in each update though. But then you have things like SuperHuman which is on 0.99999 now and I thought after 0.99 it'd be 1.0.
