The Grand 3.1.1?

According to this article from Steinberg support (macOS Sierra: Steinberg Software Compatibility Information) the Grand 3 is compatible with macOS Sierra when you update to 3.1.1

However, when I go to downloads for the Grand, there is no 3.1.1 update available…

Can someone please explain what the matter is?
