Changes since 5.1.1
- Added schema for 1.21.110.26 beta.
Caution
Mojang didn't bump the blockstate version for this change.
It's not the first time they've done this, so the PocketMine-MP reference implementation already accounts for this (e.g. in 1.18.x), but due to community misunderstanding on the use of the blockstate version field (e.g. in the case of Chunker), you might have problems upgrading non-vanilla worlds from 1.21.100 or earlier.
See #22 for more details.
