I don't know that it's a deal breaker unless you have a bunch of MAPR fees that aren't also PPFCs. Here's what the release notes say:
An issue that caused a fee that is financed into the loan amount and that is not a prepaid finance charge for APR calculations but is a MAPR fee to be double counted in the MAPR calculation has been corrected.
Previously, when the loan included a financed fee that was not a prepaid finance charge but is a MAPR fee, when the MAPR calculation was run, the fee was included in the MAPR calculation twice—once as a MAPR fee and once as a non-MAPR fee, resulting in a MAPR calculation that was a bit low, since the MAPR was being calculated as if the principal amount for the loan was greater by the amount of the additional fee. The lower the loan amount, the more fees increase the APR; and the higher the loan amount, the less fees increase the APR.
