I’ve been using R5 MK II Firmware Version 1.0.2 since it released on Dec 5th but not seeing it on this helpful site. I notice I didn’t see that firmware when selecting Windows 11 OS on Canon’s R5M2 download page, but shows up when selecting MacOS 14 or whatever. The new firmware runs mostly fine but I was able to cause the camera to hard freeze while messing with Favorites/Settings.
