The milling is so the rims will seat. The center bore of the rims is still smaller than the outer diameter of the hub (except on the light-duty 1" rotors), even in the new version. There was a different issue with the grease caps and center caps that actually was solved with the -3AA revision.

The issues still exist. They're supposedly gonna try again, but don't hold your breath -- if they do it at all, I expect it will be a year or more before they start rolling off the line.



SUMMARY:
Even in the latest -3AA revision:

1. These wheels will not fit without modification on the front except on light-duty (1" thick) rotors.
2. These wheels have the wrong backspacing in the rear and will require spacers (exact size of the spacers depends on which size you choose) unless you really don't care about your tires rubbing. They may bolt on, but likely they will be so close to the bed side that they will rub when the body shifts or suspension flexes, especially with a trailing-arm rear end.
