Prior to the beta realease each scrambled code was treated as an individual, instead of attacking the scrambler itself. Since the descrambler works for all versions implemented, Amazon cannot simply switch to a previously unused version anymore.

Also, I might be confusing things a bit here, but I think that Amazon didn't actually
change their DRM, just made it harder to access the easier-to-break formats.
