I don't know if I am on the latest version, but I am on v. 1.31 for my D500. You should be able go to Nikon's webpage and get information what is the latest firmware update.

If the current firmware revision is 1.31 it looks like there’s been more than one. C = the camera firmware revision LD = the lens distortion control version
