I don't know my version or loader
As of Minecraft 1.21.9, the DimWorldBorder mod is obsolete, as the functionality for independently configuring world borders for each dimension will be added to the base game!
DimWorldBorder is a mod for Minecraft 1.21 on NeoForge/Fabric, enabling server administrators to customize world borders independently for each dimension (Overworld, Nether, End, and others).
Server-side only; no client installation required.
