- Fixed a startup probe race condition that caused main containers to remain stuck in "Initializing" state when sidecar containers with startup probes had failed initially but succeeded on restart in pods with `restartPolicy=Never`. ([#133072](https://github.com/kubernetes/kubernetes/pull/133072), [@AadiDev005](https://github.com/AadiDev005))...

- Fix kubelet to properly log when a container is started. Previously, kubelet may log that container is dead and was restarted when it was actually started for the first time. This behavior only happened on pods with initContainers and regular containers. ([#91469](https://github.com/kubernetes/kubernetes/pull/91469), [@rata](https://github.com/rata))...

  - The `Node` authorization mode no longer allows kubelets to delete their Node API objects (prior to 1.11, in rare circumstances related to cloudprovider node ID changes, kubelets would attempt to delete/recreate their Node object at startup) ([#71021](https://github.com/kubernetes/kubernetes/pull/71021), [@liggitt](https://github.com/liggitt))

- Added metrics for volume reconstruction during kubelet startup. ([#115965](https://github.com/kubernetes/kubernetes/pull/115965), [@jsafran...

* rkt version 1.23.0+

    * known issues with the rkt runtime are [listed in the Getting Started Guide](https://kubernetes.io/docs/getting-started-guides/rkt/notes/)

* etcd version 3.0.17

* Go version: 1.8.3. [Link to announcement](https://groups.google.com/d/msg/kubernetes-dev/0XRRz6UhhTM/YODWVnuDBQAJ)

* The following deprecated flags were removed from `kubelet`:

  * `api-servers` - add apiserver addresses to the kubeconfig file instead.

  Don't use these flags. Using deprecated flags causes the kubelet to print a warning. Using a removed flag causes the kubelet to abort the startup.

*   Kubelet no longer removes default labels from Node API objects on startup ([#54073](https://github.com/kubernetes/kubernetes/pull/54073),[ @liggitt](https://github.com/liggitt))
*   The overlay2 container disk metrics for Docker and CRI-O now work properly. ([#54827](https://github.com/kubernetes/kubernetes/pull/54827),[ @dashpole](https://github.com/dashpole))

  - ip-mask-agent addon starts to use the label `node.kubernetes.io/masq-agent-ds-ready` instead of `beta.kubernetes.io/masq-agent-ds-ready` as its node selector.
  - 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.

- Kubelet: Fixed a startup crash in devicemanager. ([#113021](https://github.com/kubernetes/kubernetes/pull/113021), [@rphillips](https://github.com/rphillips))
- Kubelet: fixed log spam from kubelet_getters.go `Path does not exist`. ([#112650](https://github.com/kubernetes/kubernetes/pull/112650), [@rphillips](https://github.com/rphillips))

- Fixed vSphere cloud provider not to skip detach volumes from nodes at kube-controller-startup. ([#117243](https://github.com/kubernetes/kubernetes/pull/117243), [@jsafrane](https://github.com/jsafrane)) [SIG Cloud Provider]
