It's not official, it's a fanmade update. If you check the sign in the players room it shows it's still the V8 update... so it's pretty unofficial. Plus the sprites suck so bad on the supposed 9.2 update... at least most the new sprites do. And there's a lot of changes that feel like someone (who isn't part of the team) made, like how you can buy god stones and potaras and ape tails in the shop at 7 Island.
