It looks to me like there are two versions of this album: one in a standard jewel case, and one in a digipak. For example, here is an auction of a jewel case one:

and here is a digipak one:

Can anyone confirm that there are actually two different packaging styles? If there are: do the albums have any differences other than the outer packaging?
