- .36 is often recommended for very old machines, it seems to be a sweet spot for classic games being run on older machines
- .37 ended the beta numbering scheme, and jumped from .37b16 to .53
- .55 is recommended for low end machines. As far as I can really tell, there isn't anything specifically "great" about .55, it's just recommended very often (as I recommended in that quote above lol). It's more of a general timeframe than anything else IMO. Something in the .55 area is a good "sweet spot" in my mind for slightly older systems
I don't really use newer versions since I've been too lazy to update, but some big ones I can think of (without knowing actual versions)
- .92 as you mentioned for the sound rewrite
- Introduction of newer Golden Tee games was pretty big to many people (.9x maybe?)
- Multiple mice change is very recent and big IMO (.105ish??)
