Finally got around to getting FastQuit 3.0.0 out of beta!

• rewrote config system (now uses Cloth Config API)
  • if you are updating from 2.x or older you will have to reconfigure your FastQuit options
• added a new option "Allow multiple running Worlds", if disabled you won't be able to join a new singleplayer world until the one in the background has finished saving
  • this is to prevent some mod conflicts and will automatically disable itself when an incompatible mod is detected
  • fixes an issue with Quilt Standard Libraries
• added some new translations:
  • Estonian (thanks Madis0)
  • Traditional Chinese (thanks notlin4)
  • Ukrainian (thanks BurrConnie)
  • Vietnamese (thanks ImVietnam)
• updated some translations:
  • Simplified Chinese (thanks GodGun968)
  • Italian (thanks Oondanomala)

Please note that some of these translations were made before newer updates and might be incomplete.
