removed the `.ImagePullPolicy` field in the v1alpha2 API version. Instead it's set statically to `IfNotPresent` for all required images. If you want to always pull the latest images before cluster init (as `Always` would do), run `kubeadm config images pull` before each `kubeadm init`. If you don't want the kubelet to pull any images at `kubeadm init` time, for example if you don't have an internet connection, you can also run `kubeadm config images pull` before `kubeadm init` or side-load the images some...

    * try to only update vm if detach a non-existing disk when got <200, error> after detach disk operation
* fix pod stuck issue due to corrupt mnt point in flexvol plugin, call Unmount if PathExists returns any error ([#75234](https://github.com/kubernetes/kubernetes/pull/75234), [@andyzhangx](https://github.com/andyzhangx))

- `apiserver`, if configured to reconcile the `kubernetes.default` service endpoints, checks if the configured Service IP range matches the apiserver public address IP family, and fails to start if not. ([#106721](https://github.com/kubernetes/kube...

- kube-proxy

  - the `--resource-container` flag has been removed from kube-proxy, and specifying it will now cause an error. The behavior is now as if you specified `--resource-container=""`. If you previously specified a non-empty `--resource-container`, you can no longer do so as of kubernetes 1.16. ([#78294](https://github.com/kubernetes/kubernetes/pull/78294), [@vllry](https://github.com/vllry))

- If the user specifies an invalid timeout in the request URL, the request will be aborted with an HTTP 400.

- Fixed StatefulSet to show the valid status even if the new replica creation fails. ([#112084](https://github.com/kubernetes/kubernetes/pull/112084), [@gjkim42](https://github.com/gjkim42)) [SIG Apps and Testing]

- If `kube-proxy` mode  is userspace do not enable `EndpointSlices`. ([#100913](https://github.com/kubernetes/kubernetes/pull/100913), [@JornShen](https://github.com/JornShen))

pods running with a service account may only reference secrets specified in the service account's secrets field. Kubernetes clusters are only affected if the ServiceAccount admission plugin and the `kubernetes.io/enforce-mountable-secrets` annotation are used together with ephemeral containers.

**Note**: This only impacts the cluster if the ServiceAccount admission plugin is used (most cluster should have this on by default as recommended in https://kubernetes.io/docs/reference/acces...

  // For storage quota, the larger value from allocatedResources and PVC.spec.resources is used.
  // If allocatedResources is not set, PVC.spec.resources alone is used for quota calculation.
  // If a volume expansion capacity request is lowered, allocatedResources is only
  // lowered if there are no expansion operations in progress and if the actual volume capacity
  // is equal or lower than the requested capacity.
