* Update kube-proxy image to be based off of Debian 8.6 base image. ([#39695](https://github.com/kubernetes/kubernetes/pull/39695), [@ixdy](https://github.com/ixdy))
* Fixes an HPA-related panic due to division-by-zero. ([#39694](https://github.com/kubernetes/kubernetes/pull/39694), [@DirectXMan12](https://github.com/DirectXMan12))

- Fixed a regression in the pod binding subresource to honor the `metadata.uid` precondition.
  This allows kube-scheduler to ensure it is assigns node names to the same instances of pods it made scheduling decisions for. ([#116550](https://github.com/kubernetes/kubernetes/pull/116550), [@alculquicondor](https://github.com/alculquicondor))

- This PR added tracing support to the kubelet's read-only endpoint, which currently
  does not have tracing. It makes use of the `WithPublicEndpoint` option to prevent callers
  from influencing sampling decisions. ([#121770](https://github.com/kubernetes/kubernetes/pull/121770), [@frzifus](https://github.com/frzifus)) [SIG Node]

- Clean ReplicaSet by revision instead of creation timestamp in deployment controller ([#97407](https://github.com/kubernetes/kubernetes/pull/97407), [@waynepeking348](https://github.com/waynepeking348)) [SIG Apps]
