Yesterday Apr, 16 2020, on the Nikon Download center, the 1.11 firmware update has been published.
The only thing that's been added is support for the Fn2 button (present in some lenses, currently only the Nikkor-Z 70-200/2.8 ).
If you don't have the 70-200mm lens, you don't need to hurry to install the upgrade.
Ciao from Massimo
