Only a small config update for the most part.
The addon now uses Kiory's new SA80s (which are less error prone than the one currently used by my addon).
The class names for backpacks have also changed, so now all the "Brit_" prefixes have been replaced with "STKR_"
The whole addon download has been updated to include the new config as well as the .bikey for servers.
There should also be a downloa link to just the new config if you already have the addon :)
All the best.
