What's the background of the message? My OS is "brand-new" and based of the image of 20210911, not 20210915.
Linux rAudio 5.10.74-1-raspberrypi4-ARCH #1 SMP PREEMPT Mon Oct 18 11:50:30 MDT 2021 aarch64 GNU/Linux
What's special with 20210915?

New post partly nonsense. I've to rethink about the topic.

Recent updates have cleaned up most of weak points for critical improvements. I'd like to limit them to about 1 month back to narrow down issues. It takes only 10-15 minutes to download-flash-restore a new image while it's a lot more to solve an issue.

You may force update by long-press Update to the latest release. It could be fine or it might break something. I don't know.

long press worked fine for me.....YMMV
