* New Kubelet flag `--enforce-node-allocatable` with a default value of `pods` is added which will make kubelet create a top level cgroup for all pods to enforce Node Allocatable. Optionally, `system-reserved` & `kube-reserved` values can also be specified separated by comma to enforce node allocatable on cgroups specified via `--system-reserved-cgroup` & `--kube-reserved-cgroup` respectively. Note the...

- Added the feature gates `StrictCostEnforcementForVAP` and `StrictCostEnforcementForWebhooks` to enforce the strict cost calculation for CEL extended libraries. It is strongly recommended to turn on the feature gates as early as possible. ([#124675](https://github.com/kubernetes/kubernetes/pull/124675), [@cici37](https://github.com/cici37)) [SIG API...

* 'none' can now be specified in KubeletConfiguration.EnforceNodeAllocatable (--enforce-node-allocatable) to explicitly disable enforcement. ([#59515](https://github.com/kubernetes/kubernetes/pull/59515), [@mtaufen](https://github.com/mtaufen))

workload types.  Examples include native linux containers, and “sandboxed” containers that isolate the container from the host kernel.

The CustomCFSQuotaPeriod alpha feature enables node administrators to change the default period used to enforce CFS quota on a node.  This can improve performance for some workloads that experience latency while using CFS quota with the default measurement period.  Finally, the SIG continues to focus on improving reliability by fixing bugs while working out...
