Feel that the Nether is too short? This datapack will help. This is a simple datapack that increases the generation height from 128 to 256, and the build height to 384, so building can still be done above the Nether ceiling, for those who like to do that.
Similar datapacks have already been made, but not compatible with 1.21.11, and this one is.
Do whatever you want with this datapack, no credit is necessary.
