- Kernel crash with Aufs storage driver on Debian Jessie ([#27885](https://github.com/kubernetes/kubernetes/issues/27885))
  - Consider running the *new* [kubernetes node problem detector](https://github.com/kubernetes/node-problem-detector) to identify this (and other) kernel issues automatically.

- File descriptors are leaked in docker v1.11 ([#275](https://github.com/docker/containerd/issues/275))

  * Upgrade Node Problem Detector to v0.4.1. New features added:

    * Add /dev/kmsg support for kernel log parsing. ([#112](https://github.com/kubernetes/node-problem-detector/pull/112), [@euank](https://github.com/euank))

    * Add ABRT support. ([#105](https://github.com/kubernetes/node-problem-detector/pull/105), [@juliusmilan](https://github.com/juliusmilan))

 - For all kinds in the API group version, a spec.selector default value is no longer
 available, because it's incompatible with `kubectl
 apply` and strategic merge patch. You must explicitly set the spec.selector value
 in your manifest. An object with a spec.selector value that does not match the labels in
 its spec.template is invalid.

 - Selector mutation is disabled for all kinds in the

  - kube-proxy addon starts to use the label `node.kubernetes.io/kube-proxy-ds-ready` instead of `beta.kubernetes.io/kube-proxy-ds-ready` as its node selector.
  - metadata-proxy addon starts to use the label `cloud.google.com/metadata-proxy-ready` instead of `beta.kubernetes.io/metadata-proxy-ready` as its node selector.
