Hi! Could you please update the mod What's That Slot? to version 1.21.4 for the Fabric library? In my opinion, version 1.21 is no longer as popular for mods as 1.21.4. I would really appreciate it and would be even more engaged in the game.

Done! :) https://github.com/Gegy/whats-that-slot/releases/tag/v1.3.7%2B1.21.4

Could you please provide a version of this mod on the official sites Modrinth and CurseForge? I would be very grateful to you.
