  - Privilege escalation has been disabled for all containers. ([#82347](https://github.com/kubernetes/kubernetes/pull/82347), [@pjbgf](https://github.com/pjbgf))
- Kubernetes no longer monitors firewalld. On systems using firewalld for firewall
  maintenance, kube-proxy will take slightly longer to recover from disruptive
  firewalld operations that delete kube-proxy's iptables rules.

* Fixes issue for readOnly subpath mounts for SELinux systems and when the volume mountPath already existed in the container image. ([#64351](https://github.com/kubernetes/kubernetes/pull/64351), [@msau42](https://github.com/msau42))

In addition, the NodeRestriction admission plugin now prevents kubelets from modifying taints on their Node API objects, making it easier to keep track of which nodes should be in use.

### SIG CLI

### SIG Windows

- Kubelet no longer attempts to sync iptables on non-Linux systems.. ([#67690](https://github.com/kubernetes/kubernetes/pull/67690), [@feiskyer](https://github.com/feiskyer))
- Kubelet no longer applies default hard evictions of nodefs.inodesFree on non-Linux systems. ([#67709](https://github.com/kubernetes/kubernetes/pull/67709), [@feiskyer](https://github.com/feiskyer))

## Known Issues

- The etcd and KMS plugin health checks are not exposed in the new `livez` and `readyz` endpoints. This will be fixed in 1.16.1.

- Fixed a bug where containers would not start on `cgroupv2` systems where `swap` is disabled. ([#120784](https://github.com/kubernetes/kubernetes/pull/120784), [@elezar](https://github.com/elezar))

  Plugin `SelectorSpread` is removed in v1. ([#110534](https://github.com/kubernetes/kubernetes/pull/110534), [@kerthcet](https://github.com/kerthcet))

### CSI Health Monitoring

The CSI health monitoring feature is being released as a second Alpha in Kubernetes 1.21. This feature enables CSI Drivers to share abnormal volume conditions from the underlying storage systems with Kubernetes so that they can be reported as events on PVCs or Pods. This feature serves as a stepping stone towards programmatic detection and resolution of individual volume health issues by Kubernetes.
