Message configs are now selected based on the client's language (can be
toggled in the config) and will use MineDown formatting to allow
display of component messages as well as usage of RGB colors in 1.16.
If found the legacy local.yml will be used instead of the per-language
files. Move your local.yml to the correct lang config to if you want to
use the per-client language option.
Version was also changed to 3.11 due to the many internal changes that
have accumulated over time
The InventoryMoveItemEvent is now only used for Hopper Minecarts, other blocks that could move items (Hoppers and Droppers) are checked on place. That way players that have access to a shop can just use the blocks normally but other players can't place them.
