FW 1.20 is new. They released it today, but the file date is 22-OCT. That's a typical time to release.
I'm hoping for a miraculous cold battery fix, but let's see if someone can test it first. I won't be in a frozen zone for weeks.

Cold battery fix number 1..
You beta testers let me know how it goes so I'll know whether to update or not in January.
I'm going to cold weather soon for the first time in my life really. I don't know what to do, maybe one of each R5, R5 II, a7rV and hope something works? There was one FW for the R5 II that supposedly had a negative impact on the AF, so I'm a bit leery about it.

Last time in Yellowstone in winter was with R5. No problem but I'm not really sure what the minimum temperature was since I've never had battery problems in winter going all the way back to the Ftb. Therefore, I wasn't really paying attention to how cold it got.. I too am faced with this problem. I've photographed in Yellowstone at -20F etc with cold soaked EF equipment outside all day. Had to sit at the gate once waiting for it to warm up so park service would let us in at West Yellowstone and -30F at Cooke City. Most of the reports about cold with R5II seem to be +20F hockey games not real cold by my definition. I bought a two battery grip which reportedly helps and plan to take an R5 as backup. I did external batteries once with a T-90 which was awkward and unnecessary so the idea of a big lithium battery connected with a usb C cord is not very attractive. Bunch of extra batteries I guess. This will be in snow coaches not snowmobiles so equipment will not be as cold soaked and -20F is usually first light not all day. Tundra Buggies in Churchill not a big of cold stress as you photography from inside and have limited time on rear platform etc. Not experienced -0F there or Antarctica. Not sure if that helps but I've got the same problem you do. As a nature photographer, between "who cares" updates, lens envy for things not available from canon, canon's lock out ot 3rd parties etc, I'm really thinking it may be time to move to Sony (can't believe I said that) or Nikon. I did have a Nikonos once and a Sony (with a terrible menu) once so.............
