This file works on Minecraft 1.11. It also works on Minecraft 1.9 and 1.10 if you have an existing config file, or if you remove the shulker boxes from a newly created config file.

• Added shulker boxes to the default list of protected containers. If you have an existing configuration file, you'll need to add those blocks manually.
• You can now place protection signs to the left or the right of a door.
• Trapdoors can now be opened and closed automatically, just like doors.
• Added sounds to auto-closing (trap)doors
• Fixed [Timer: X] (with a space between : and X) not working.
• Made some block checks done by the plugin a bit faster.
