### Bug or Regression

- Fix Azure file share not deleted issue when the namespace is deleted ([#97417](https://github.com/kubernetes/kubernetes/pull/97417), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]

    will be enforced on all pods by default. To opt-out set
    `--enforce-node-allocatable=””`
  * Hard Eviction Thresholds will be subtracted from Capacity while calculating
    Node Allocatable. This will result in a reduction of schedulable capacity in
    clusters post upgrade where kubelet hard eviction has been turned on for
    memory. To opt-out set `--experimental-allocatable-ignore-eviction=true`.

- Multiple Kubernetes clusters can now share the same resource group
    - When upgrading from previous releases, issues will arise with public IPs if multiple clusters share the same resource group. To solve these problems, make the following changes to the cluster:

  * 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.

* Fix inconsistent Prometheus cAdvisor metrics.

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. This field is alpha and can be...

  in kube-apisever and kube-controller-manager pods. Instead, it shifted to supporting the
  mounting of /etc/pki/ca-trust and /etc/pki/tls/certs. The locations /etc/ca-certificate,
  /usr/share/ca-certificates, /usr/local/share/ca-certificates, and /etc/ssl/certs continued
  to be supported. ([#124361](https://github.com/kubernetes/kubernetes/pull/124361), [@neolit123](https://github.com/neolit123))
