Your choice. This is what's changed, mostly related to streaming (the "HDR Certification" is related to Amazon Prime streaming, I think). There is a way to connect but block updates, but you need control of a local DNS server, and be able to block access from the TV to Google DNS (220.127.116.11). I skipped 18.104.22.168, and when I upgraded from 22.214.171.124, it did it in steps, so I could have stopped at 126.96.36.199. But I can't guarantee that behavior - it may go directly to the latest for some? But I'd think 188.8.131.52 might be worthwhile. You'd have to search the earlier parts of this thread to see what problems were associated with 184.108.40.206.
