Filament Run Out Sensor Questions

1.) Has the firmware been updated so I can run two on my dual extrusion system?

2.) I am having issues with "glossy" filament not being detected. Is there a way to adjust the sensitivity or handle these filament types?
OK so I answered number two after looking at the sensor more, it is not optical. So I just bent the switch to protude further and problem solved. But still wondering about the dual extrusion.
