….21.0-25 Warn clusters with KubeletConfigs upgrading from 4.20.24 or earlier to any existing 4.21.z that auto-sizing-disabled MachineConfigs may override KubeletConfig autosizing settings on custom MachineConfigPool nodes. Uses PromQL matching on apiserver_storage_objects to scope the risk to clusters that have KubeletConfigs, per Trevor's recommendation. The fix (openshift/machine-config-operator#5885) shipped in 4.20.25. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> Signed-off-by: Sahil Shah <[email protected]>

Poking into the implementation, I don't think 4.20.25 is sufficient, and I've reported the issue as OCPBUGS-99650 . I don't think we should be raising the floor until we know when it's actually fixed. And given the low impact rate and the number of clusters who would be updated by a floor-raise, it might be too late in the 4.20.z lifecycle to declare at all?

Summary
Combined PR: raises
minor_minfrom 4.20.15 to 4.20.25 for future 4.21.z builds, and adds conditional update risk for all existing 4.21.z GA releases (4.21.0 through 4.21.25).Cherry-picks the build-suggestions change from #9494 (by @aksjadha) and adds the companion blocked-edge files requested by @sdodson and @wking.
Replaces #9494 and #10046.
