Garzo, Hrenya and Dufty (GHD) model

I am wanting to use the GHD model for bidisperse mixtures, but I cannot tell if the model implemented into MFIX has been updated with any of Garzo’s corrections from his 2011 paper. The references in the files only show the original 2007 paper and references to notes. Does anyone know if this model was updated with the formula corrections of the 2011 paper?
