Enabling seccomp for your workload can have a negative performance impact depending on the kernel and container runtime version in use.
  

    * Add hugepages monitoring support
    * Fix incorrect CPU usage metrics with 4.7 kernel
    * Add tmpfs monitoring support
* Support for Huge pages in empty_dir volume plugin ([#50072](https://github.com/kubernetes/kubernetes/pull/50072), [@squall0gd](https://github.com/squall0gd))
    * [Huge pages](https://www.kernel.org/doc/Documentation/vm/hugetlbpage.txt) can now be used with empty dir volume plugin.

- Add `/sys/devices/virtual/powercap` to default masked paths. It avoids the potential security risk that the ability to read these files may offer a power-based sidechannel attack against any workloads running on the same kernel.

- Fix a bug that Pods could stuck in the unschedulable pod pool 

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions.

The RuntimeClass alpha feature enables a node to surface multiple runtime options to support a variety of workload types.  Examples include native linux containers, and “sandboxed” containers that isolate the container from the host kernel.

- SCTP support in API objects (Pod, Service, NetworkPolicy) is now GA.
  Note that this has no effect on whether SCTP is enabled on nodes at the kernel level,
  and note that some cloud platforms and network plugins do not support SCTP traffic. ([#95566](https://github.com/kubernetes/kubernetes/pull/95566), [@danwinship](https://github.com/danwinship)) [SIG Apps and Network]
