* Some container runtimes share a process (PID) namespace for all containers in a pod. This will become the default for Docker in a future release of Kubernetes. You can preview this functionality if running with the CRI and Docker 1.13.1 by enabling the --experimental-docker-enable-shared-pid kubelet flag. ([#41583](https://github.com/kubernetes/kubernetes/pull/41583), [@verb](https://github.com/verb))

When using the separate flag, the order in which they're specified doesn't matter.  ([#58123](https://github.com/kubernetes/kubernetes/pull/58123), [@hzxuzhonghu](https://github.com/hzxuzhonghu))

* The kubelet  --docker-disable-shared-pid flag, which runs docker containers with a process namespace that is shared between all containers in a pod, is now deprecated and will be removed in a future release. It is replaced by `v1.Pod.Spec.ShareProcessNamespace`, which configures this behavior....

* Sharing a PID namespace between containers in a pod is disabled by default in 1.8. To enable for a node, use the --docker-disable-shared-pid=false kubelet flag. Note that PID namespace sharing requires docker >= 1.13.1. ([#51634](https://github.com/kubernetes/kubernetes/pull/51634), [@verb](https://github.com/verb))

  * **WARNING:** A [known issue](https://github.com/kubernetes/kubernetes/issues/44041)
    in v1.6.0 causes `Pod.Spec.HostPid` (using the host PID namespace for the pod) to always
    be false. Please wait for v1.6.2, which will include a fix for this issue.
* Various scheduling features have graduated to beta:

- Fixed a bug where the Kubelet miscalculated the process usage of pods, causing pods to never get evicted for PID usage. ([#124101](https://github.com/kubernetes/kubernetes/pull/124101), [@haircommander](https://github.com/haircommander)) [SIG Node and Testing]

* Added CheckNodePIDPressurePredicate to checks if a pod can be scheduled on ([#60007](https://github.com/kubernetes/kubernetes/pull/60007), [@k82cn](https://github.com/k82cn))
    * a node reporting pid pressure condition.
* Upgrade Azure Go SDK to stable version (v14.6.0) ([#63063](https://github.com/kubernetes/kubernetes/pull/63063), [@feiskyer](https://github.com/feiskyer))
