We are currently running ML7. Our understanding was that if we upgraded to ML8 that we would then be ready for the new API. But comparing the USPS related code in 7 and the new code in 8, we're seeing that it is the same. Is that possible? Can anyone detail any specifics that are different with the new API that we might be missing? Is there any documentation on what specifically is changing and/or needs to be changed to be ready for August 24, 2011?
