REVISION Information:

On July 31st, 2013, a new patch is released.  The only change is in the CommerceBuilder.USPS.dll*.  The correction was made so that Military APO AE addresses will work.  The original AbleCommerce Gold patch,  released on July 28th, used the "MILITARY" word in service codes (following the provided USPS release notes), but it did not match the actual service results returned from USPS.
