Does pros support the V5 Optical Sensor? If not when could we expect to see it supported?
Not yet, but it will.
Any idea of a ballpark date?
Being an open source project, you can check progress on development of these two sensors here:
Just an update the branches that add support for these sensors have been merged into develope. IDK what the state is but if you can find the pre-release binaries you can test it.
