- The NodeShutdown taint is now supported for Azure. ([#68033](https://github.com/kubernetes/kubernetes/pull/68033), [@yastij](https://github.com/yastij))

### SIG CLI

  * OOM parser uses kmsg
  * Add hugepages support
  * Add CRI-O support

* Sharing a PID namespace between containers in a pod is disabled by default in version 1.8. To enable for a node, use the `--docker-disable-shared-pid=false` kubelet flag. Be aware that PID namespace sharing requires Docker version greater than or equal to 1.13.1.

* Fix issues related to the eviction manager.

- Pod process namespace sharing is now Generally Available. The `PodShareProcessNamespace` feature gate is now deprecated and will be removed in Kubernetes 1.19. ([#84356](https://github.com/kubernetes/kubernetes/pull/84356), [@verb](https://github.com/verb))

### Staging Repositories

- The CRI API is now available in the `k8s.io/cri-api` staging repository. ([#75531](https://github.com/kubernetes/kubernetes/pull/75531), [@dims](https://github.com/dims))

- Empty values are no longer assigned to undefined resources (CPU or memory) when storing the resources allocated to the pod in checkpoint. ([#117615](https://github.com/kubernetes/kubernetes/pull/117615), [@aheng-ch](https://github.com/aheng-ch))
- Fixed CEL estimated cost of `replace()` to handle a zero length replacement string correctly.

- Migrate staging/src/k8s.io/apiserver/pkg/audit/policy/reader.go logs to structured logging. ([#98252](https://github.com/kubernetes/kubernetes/pull/98252), [@lala123912](https://github.com/lala123912)) [SIG API Machinery and Auth]

- Improved scheduler performance when no scoring plugins were defined.

* 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))

  - Include taints by condition when determining if a node is unready/still starting
  - Fix `update-vendor.sh` to work on OSX and zsh
  - Add best-effort eviction for DaemonSet pods while scaling down non-empty nodes
  - Add build support for ARM64
  
  ### AliCloud
  - Add missing daemonsets and replicasets to ALI example cluster role
  

runs a process in an existing container. Also like `kubectl exec`, no resources are reserved for ephemeral containers and they are not restarted when they exit. Note that container namespace targeting is not yet implemented, so [process namespace sharing](https://kubernetes.io/docs/tasks/configure-pod-container/share-process-namespace/) must be enabled to view process from other containers in the pod.
