IMPORTANT: Be sure to update Chunky when updating ChunkyBorder. This update in particular requires at least version 1.1.20.
Added a new configuration option align-to-chunk which determines whether the border edges should snap to chunk boundaries (e.g. to 512 instead of 500). This was the default behavior prior to this update, but it isn't anymore since it was not very intuitive to most people, so if you need this you will have to re-enable it.
