This is a one-off backport of BlueMap 5.12 for Forge 1.20 - 1.20.4 (including 1.20.1) due to very high demand.
This Version needs Java 21 to run!
Forge and most mod's should be able to run on Java 21 instead of Java 17. If you can't use Java 21, then you need to use BlueMap 5.3 instead.
Upgrading from 5.3
The previous BlueMap version that supported Forge 1.20.x was 5.3, so you are likely upgrading from there.
There have been a ton of changes and new config values etc., so I really recommend you to do a full clean installation of BlueMap:
- Stop the server
- Make a backup
- Delete your current ./mods/bluemap-x-yz.jar
- Delete the ./config/bluemap
- Delete the ./bluemapdirectory
- Put the new bluemap-5.12-mc1.20-6-forge.jarin the./modsfolder
- Start the server
- Reconfigure BlueMap again, using the newly generated configs
 You can keep the configs from your backup aside, to help you with the porting
- run /bluemap reload
If you don't want to do a clean installation to keep your currently rendered maps, you need to follow the upgrade-steps from these changelogs:

- https://github.com/BlueMap-Minecraft/BlueMap/releases/tag/v5.11
