An update for MentionChat has been released! This adds many new features, ranging from managing player settings to changing the mention symbol!
Here are the new stuff that has been added:

• New /mentionchat subcommands!
  • /mentionchat info - Same as /mentionchat, view MentionChat's info and perform an update check
  • /mentionchat help (1/2) - View the MentionChat help page
  • /mentionchat settings <toggle/format/sound> - Lets players manage their settings for MentionChat
• Players can now manage their settings for MentionChat
  • /mentionchat settings toggle - Changes if the player can be mentioned by others
    Bypassed with mentionchat.mention.bypass / mentionchat.mention.bypass.toggle
  • /mentionchat settings format <format> - Changes the format for the mentions
    Default is set in the config
  • /mentionchat settings sound <sound> - Changes the sound that plays when being mentioned
    Default is set in the config. Must be a valid sound ENUM.
• Added tab completion for /mentionchat
  
• You can now change the symbol used for mentioning someone, or have none at all! (JovannMC instead of @/JovannMC)
  Having none can cause players with mentionchat.mention.everyone to mention everyone unintentionally
• Players can be given mentionchat.mention.exempt to be exempt from being mentioned, no matter their toggle status.
  This can be bypassed with mentionchat.mention.bypass
• Removed mention type "MESSAGE"
  No reason why you should use this over "FORMAT", really, so it's been removed
• Removed warning in the console when the server is on a legacy version and using the default sound
  Instead, a new config file is generated for legacy versions which uses a sound that supports the legacy version.
• New permission nodes/commands
  
• New config version
• Bug fixes and minor QOL improvements

This release updates the config version, so please delete and reconfigure the config's plugin for the new entries!
