In order to be consistent with the changes to stairs and slabs, blocks like pistons, droppers and dispensers can now be rotated sideways while standing and up / down while sneaking
Armor stands can now be rotated! When sneaking they rotate in smaller increments. You can add "armor_stand" to the blacklist if you don't want to rotate them.
This update changes the structure of the config.yml. It is recommended that you delete your old config.yml when upgrading to 1.4.0 from older versions.
The crafting recipe can now be customized in the config.yml
Wrenches now have an enchantment glint (can be disabled in config.yml)
With this update players can now only rotate blocks in regions where they have permission to break blocks in. This should support almost all region protection plugins!
