The last FW is good enough for KK3 and AZW3/KF8. FW 3.4.3

I don't know when they added azw3 to FW, maybe 3.2.x? Certainly the last FW for DXG and other models before KK3 is 2.5.8 and only does KF7 (old mobi, azw and maybe some other old formats) and PDF.

The KK3 didn't have azw3 support when I got it s/h, but did after I did a manual FW update. I think the KK4 etc had azw3 from launch.
If there is "Publisher" as an option under Aa then it does AZW3/KF8.
Oddly the KK3 manages images more accurately, the last FW on my PW3 (not been updated since maybe 5.12.x) sometimes does image sizes badly.
