If you do the update you will have to regenerate your config.yml or add the changes manually (see below)
You can now allow to use an EnderPearl in creative mode (idea of @TheRealJoelmatic)
Code (Text):
#Choose the sound sent to the player when using an EnderPearl (Set false to disabled)
#To know the list of possible sounds, consult the page: https://helpch.at/docs/X/index.html?org/bukkit/Sound.html
#Replace the X in the URL with the version of your server (1.8.8 for example)
sound: LEVEL_UP
#Allow the possibility to use an EnderPearl in gamemode creative
#(true = allowed, false = not allowed)
enderpearl_creative: true
