* The `system-node-critical` and `system-cluster-critical` priority classes are now limited to the `kube-system` namespace by the `PodPriority` admission plugin. ([#65593](https://github.com/kubernetes/kubernetes/pull/65593), [@bsalamat](https://github.com/bsalamat))

### Other notable changes

## Known Issues

- A new kubelet command line option, `--reserved-cpus`, is introduced to explicitly define the CPU list that will be reserved for system. For example, if `--reserved-cpus=0,1,2,3` is specified, then cpu 0,1,2,3 will be reserved for the system.  On a system with 24 CPUs, the user may specify `isolcpus=4-23` for the kernel option and use CPU 4-23 for the user containers.
