🛠️Notes/Changes

OptimumFuse is now again available for 1.21.1, which means a lot of missing features are now available, and the pack is more stable than ever. There is a plethora of new features for you to discover.
- This also means support for all versions above 1.21.1 has been dropped, for now.
- Thanks to @MissionWAR for helping test and providing helpful feedback.
