What is new?
The different administrator commands now have separate optional permissions. The permission claim.admin.remove gives access to the admin remove and clear commands. claim.admin.show allows you to use the admin show command. To reload the configuration file or to create new permission group files, you need claim.admin.config. And lastly, to update the flags of all regions or to purge them, you need claim.admin.update.
Good to know: the old claim.admin permission still exists, and still grants access to all admin commands for backwards compatibility.

How to update?
Download the jar file from the top of this page and put it in your plugins folder. Make sure to remove the previous version of this plugin. Now restart ( not reload) your server and you are done!
