That's a really good point...
So far from v21, other than the things we initially got like S&S and enviroment settings, all we've gotten is:
Treasure chests
PP
Teledoors
doors
skulls, coffin
balls
snowballs
speedkarts and modterrain became default
setvehiclepowered, onminigamereset, camera events added
and bots
Which while it is a lot of stuff, they're all just add-ons. Where's the actual updates?
