I am the new maintainer of this plugin. I plan to continue this plugin's development far into the future.
This contains the changes from 2.3.9 through 2.3.12.

2.3.9 and 10:
Added: Add me as a maintainer in the info command an in the main class. Also added myself to 'authors' in plugin.yml
Added: Added the /awf world command. Displays the world you are currently in to make /awf add/remove easier to use. This will likely be replaced in a future update.

Fix: Ensure that colours are displayed instead of an ampersand and the colour code.
Fix: Stopped sending the 'awf-tip' to the console when the help command is run.
Fix: Switched the ' world' in /awf help to <world> for added clarity and for better looks in the console.

2.3.11:
Fix: Change update download location to the new Spigot resource page
Added: Lang file updater for changes made in v2.3.10
Changed the default values under antiFlyWorlds in config.yml

2.3.12:
Switched the in game update checker to refer to this page instead of a replacement listing created due to this resource being temporarily unavailable.

This was tested on 1.7.9, 1.8.8, 1.12.2, and 1.16.4 and all seems to be working. If you encounter any issues don't hesitate to open an issue on the plugin's GitHub.
