According to https://www.kernel.org/category/releases.html?utm_source=copilot.com ...

The 5.10 LTS version, which runs on many of our nodes, will hit EOL in December.
Some notes (e.g., Pat Price) already run a newer version (6.1 in the Pat Price case).

We should upgrade all 5.10 nodes to the latest LTS version for the Pi, which is 6.12 according to https://www.raspberrypi.com/software/operating-systems/
