I just can't figure out why in all of a sudden I decided to update this abandoned mod after a whole year although it is actually very simple to maintain, as there's really few lines of code in the project and they'll probably work well no matter what mojang does to minecraft.
- added support for 1.21.x
- some (negligible) fixes
Just found a way to support mc version 1.19.3-1.20.6 in one .jar file.
