- Marked as compatible with 1.20.3 and 1.20.4
- Added enforcement for the mod being on both client and server
- When a client connects to a server, if the mod is not present on both, the client will be disconnected with a message saying which side is missing the mod
- Prior versions of the mod aren't recognized, so if an old version is installed on one side and a new version on the other, the client will be disconnected
- Fabric API is now required
- Thanks to OroArmor for helping me figure out how to implement this feature!
