- Dave really meant to say that r4k Indigos are supported by 4.0.5E.
- We combined the R4K Indigo and RealityEngine support into this single
- software package which was released (engineering to manufacturing)
- last week.
-
- Yes, there was once a thing called 4.0.5D but we gave it a graceful
- retirement before it hit the field when 4.0.5E proved we could give
- support to two diverse products with one package (4.0.5E).
