The Prison Chest at /loot: spend a Prison Key to open it
An opening ceremony that reveals your haul one item at a time
Duplicate protection: pulling something you already own pays out in shards instead
Odds on the rarer items climb the more you open, and become guaranteed if it takes long enough
A common set that tracks what you have collected and resets once you complete it
Chest openings are announced to the lobby in chat
Prison Keys from the daily claim now have somewhere to be spent
Mentions in chat: type @ with part of a name and press TAB to complete it
TAB cycles through everyone who matches what you typed
A sound when somebody names you in chat
Names inside a message now carry a colour: green when it is you, blue when it is anyone else
Arrival lines in chat when someone joins the yard, with their own set of lines for a brand new inmate
