Complex numbers - Cuda 11.6 documentation warning

Documentation on Complex numbers has a note indicating that the user should use Cuda 11.6 without additional information on why this is recommended.

Cuda 11.6 is considerably old and does not support new OS versions (e.g., Ubuntu 22.04). Therefore, can anyone explain why is Cuda 11.6 is recommended and not any of the newer versions of it? What features are missing in other versions? what works/what doesn’t?

You can ignore the note as it’s related to an actual slow compilation time in 11.3 described here. We should remove it as 11.3 isn’t even built anymore in our binary matrix.
