The Z6 II (1.02) and Z7 II (1.01) both got a firmware update that fixes an issue with exposure while using flash in Auto-area AF mode.
This is probably a good time to remind you that manuals get updated sometimes, too. Originally, we had a Z6 II only reference manual, now it's a Z6 II and Z7 II reference manual. There's also a shorter User's Manual and a Technical Guide (RAW Video Recording Edition) that you can download.
In other words, any time you're going to the download center to get something, you should check the Manuals, Firmware, and Software tabs to see if there's anything new.
