The most significant difference for me so far, between version V_1.7 and V_2.4, is the new version has 30 Menu Settings, whereas the older V_1.7 had 29 Menu selections.
Of the 30 Menu Settings, I have 10 of 30 Menu settings off or not used:
Parking Mode, Time Lapse, Motion Detection, LDWS, FCWS, GPS STAMP, LED, Image Rotate, Format Warning and Custom Text
I’m satisfied with the images of the latest FW A119S_180115_V2.4
