» New Features

+ Added MySQL support for cooldowns, virtual crates/keys, and player crate history! You must have your own SQL database but other than that it just works: creates the table for you and all. (NOTE: This feature is in beta. So it should work but there may be slight issues with it because there's only so much I can test on my own. Although I did do some rigorous testing.)
Few notes: All of the code is run in a different thread except the initial database connection. So, on startup, there may be a 1s lag but other than that it should have no effect on server performance.
+ Added 'loading-from-database' message which is displayed to players when they try to interact with a crate and their information hasn't yet been loaded from the database.
+ Added SQL.YML file which includes MySQL database login information.
