How have the postprocessing routines been updated?

For version 6.40 the definitions of PM
2.5 and PM10 have been changed to correctly include PEC (Primary Elemental Carbon) and a factor is now applied to POA (Primary Organic Aerosols).  This factor was recommended by EPA to take into account for the different methodologies for converting mass of organic carbon to mass of organic materials in the emissions inventories and at monitoring sites.

The same changes apply to version 7.03 but the new, four-part SOA (Secondary Organic Aerosols) treatment is now properly implemented.
