• Added | MySQL Support (This one is for you, networks!). You may configure the database settings via the settings.yml file. You can read more about this feature in the new MySQL section of the Wiki.
• Added | /ucolor forcegradient (name|chat) (player) (color1) (color2) command for admins to force custom gradients on other users. Thanks, @xScriN_ for suggesting this feature!

• Fixed | When setting name colors via the /ucolor setnamecolor command, it tells the chat color changed instead of name color.
