This release is small and mainly patches a bug I introduced to the texture exporter when I added IFL support a month or so back. Since that update the exporter would fail if there was no bitmap in the material's diffuse slot. Now it works again with only a solid color in the diffuse.
I also made a change to the code so that the quick hull function is ready for the upcoming fix to the PhysX/MassFX functions that are broken in some versions of PhysX and MassFX. Despite this minor update, you won't be able to use Quick Hull in PhysX 2.71 (all versions of Max) or MassFX in Max 2013 until nVidia/Autodesk release the patch.
[EDIT]
After making a change to the code and testing again, WW will make hulls in Max 2013 now. It is only PhysX 2.71 that is not working.
