This update has a lot of breaking changes. I recommend backing up your config files as they may not be able to be automatically updated.
Changes: - 1.20.5/1.20.6 support - Added support for MiniMessage for color in messages - Added a servers config for blacklisted servers such as if you have an auth server and you don't want anyone to use staff chats there - A modules system to enable/disable entire parts of the plugin - Dropped support for Spigot/BungeeCord
For Velocity you need to install SignedVelocity on Spigot and Velocity servers otherwise a lot of message errors will occur such as player disconnect/kicks.
