Nether 3.0
by kohara
Nether 3.0 changes Nether worldgen with taller build limits, reworked biomes and a larger roof, and it is shipped as a data pack for the 1.20 and 1.20.1 game versions.
What it does
Nether 3.0 raises the world height to 192 blocks and adds 64 extra blocks of roof, so the Nether has more room vertically than in vanilla. Biomes are rehauled as part of the same generation changes, and the author describes the datapack as a light alteration of existing Nether generation rather than a large overhaul with many new mechanics.
Because it is a datapack, it supports multiplayer servers, including Bukkit, Spigot, Paper, Purpur and other forks. A server needs the pack, while players may add it but do not have to install it. Builds exist for Fabric, Forge and Quilt on 1.20 and 1.20.1, and the latest file, 3.51+mod for 1.20.1, was published on 2023-07-03 after a first release on 2023-07-02. The license is All rights reserved, so the mod is not open source, though its source code and issue tracker are public.

Use cases
Multiplayer servers
Server owners can install the pack on a Paper or Spigot server so players explore a taller Nether without any client changes.
Who it’s for: Server owners who want a modest change to Nether generation, and survival players who want a taller and more varied Nether without heavy additions.
How it compares
Higher Nether Max Build Height is open source under the CC0 1.0 Universal license and is published for Fabric, Forge and Quilt on 1.20.1. Its server side is needed while clients may skip it, much like Nether 3.0. Wastify is open source under the MIT License, is a Forge mod for 1.16.5 – 1.20.1 and is server-side only, so clients need nothing installed.
