How do the two differ or is it just a new printing.

How do the two differ...
Well that's just it! We don't know how they differ. We don't have the manual prior to the Aug. 14th revision.

...or is it just a new printing.
A reprinting is not a revision and would be noted accordingly as only a reprinting.

It could have vast changes that are in no way comparable to the new revised manual.
Any attempt to compare one with the other is an act of futility and to assume that they're the same is to act on evidence not on hand.
