Intended Way

In 1.21.2 Mojang fixed the sneak slime glitch, which is the most used glitch used in speedruns, because of that, from now on, all the old runs are moved into 1.20~1.21.1 category, and the default category is now 1.21.2+.

You can still submit Pre-1.21.2 runs if you want, just don't forget to
