Credits the mod to **whoisabz** — earlier builds shipped with the mod-template placeholder as the author, so launchers listed it as "ItemLock by You".
No gameplay changes from 1.9.1. If you are on 1.9.0 or 1.9.1 this is purely cosmetic; if you are on anything older, it also carries the 1.9.0 fix for locked items escaping via double-click gather and the swap-offhand key.
