* 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...

- Changed underlying logic to propagate pod-level hugepage cgroup to containers when they did not specify hugepage resources.

- ServiceAccount metadata.annotations[kubernetes.io/enforce-mountable-secrets]: deprecated since v1.32; no removal deadline. Prefer separate namespaces to isolate access to mounted secrets.

* '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))

- 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...
