Nikon quietly updated the changelog (release notes) for the last few Z camera firmware updates:
The Z9 firmware update has several new lines added, while the other two updates just “gained” support for the new Nikkor Z 400mm f/2.8 TC VR S mirrorless lens. From a software development point of view, it is a bad idea to add functionality to an already officially released version. Needless to say that users will not have a clue that the release notes were updated… Just a bad practice from Nikon and I hope they will not do it again. I do not know how far back they went to update the release notes, but the Z6II camera still doesn’t have support for the new 400mm Z lens. Maybe we will finally see the long-rumored Z6II/Z7II firmware updates being officially announced next week at the 2022 CP+ show. Stay tuned!
