Please look at the Wiki for changes **Note:** I have not tested to make sure that player data from previous versions transfers properly, *however*, I did not change anything about the format or location of the player data, so it should be fine! **Also Note:** You may need to regenerate your config files, be sure to save your reward groups before you do this so you don't lose them!

- Added singleplayer support! - Added a default rewards config with 20 rewards!
