Welcome to 4.0.0! This update brings you (good) rgb support with an amazing new component format as well as some other updates and fixes.
Added support for hex colors in messages and replaced the component parsing with adventure-minimessage
Your config and language file will mostly be updated to the new format automatically, you won't have to change anything manually except for the %NEWLINE% variable to <br>. You might still benefit from letting new config and language files generate.
This means that section symbols (`ยง`) are no longer the intended/supported format
