etcd
v3.6.9Kubernetes Coreetcd v3.6.9 is a maintenance release. The release notes are sparse — check the full CHANGELOG for the actual diff before upgrading.
breakingRead the CHANGELOG before upgrading — release notes are incomplete
The published release notes for v3.6.9 contain no change details. Before upgrading any etcd cluster, pull up CHANGELOG-3.6.md directly and diff the entries since your current version. The 3.6 series has known breaking changes, and skipping this step on a stateful system like etcd is a real risk.
enhancementVerify container image source if you pull from quay.io
etcd's primary registry is gcr.io/etcd-development/etcd. If your pipelines pull from quay.io/coreos/etcd, confirm that image is current and matches the gcr.io digest. Secondary registries can lag. Pin by digest, not just tag, to avoid silent version mismatches.
