Minecraft 26.1 and 26.3 are untested
The 26.x build was made against 26.2. If another 26.x version changed part of the game's code, a keybind might fail when you press it. If this happens, report it with your latest.log.
Quilt is not fully tested
Quilt should load the mod through its Fabric compatibility, but this has not been fully tested. Use Fabric API on Quilt.
Items must be in the hotbar
Keybinds only look for items in your hotbar. If an item is deeper in your inventory, the keybind does nothing.
Servers may flag it
The mod automates item swapping and use in timed sequences. Check a server's rules before using it on multiplayer.
