The Void Superpack

This was intended to be only a hotfix for the Industrial Revolution Update but quickly became its own full update.

The version was backported to 1.20.1

If you have a single player world you can use a tool called Amulet (It's free and on GitHub) to convert your worlds.
Process is simple. You make a new world on 1.20.1. Then open Amulet and open the World from 1.21.1 and choose the new world from 1.20.1 to convert into. This will overwrite your new 1.20.1 world with the old stuff from the 1.21.1 world but will keep most of the things expect any blocks from Create: Design n' Decor because it had to be removed due to crashing the game. (I am sorry if your worlds do have some of these blocks)
