  allows this sysctl in `v1.29+` versions of the baseline and restricted policies. ([#121240](https://github.com/kubernetes/kubernetes/pull/121240), [@HirazawaUi](https://github.com/HirazawaUi))
- `kubelet` now allows pods to use the `net.ipv4.tcp_keepalive_time` sysctl by default
  and the minimal kernel version is 4.5; Pod Security Admission allows this sysctl

- As of v1.25, the PodSecurity `restricted` level no longer requires pods that set .spec.os.name="windows" to also set Linux-specific securityContext fields. If a 1.25+ cluster has unsupported [out-of-skew](https://kubernetes.io/releases/version-skew-policy/#kubelet) nodes prior to v1.23 and wants to ensure namespaces enforcing the `restricted` policy continue to require Linux-specific securityContext fields on all pods, ensure a version...

- Added "general", "baseline", and "restricted" debugging profiles for kubectl debug. ([#114280](https://github.com/kubernetes/kubernetes/pull/114280), [@sding3](https://github.com/sding3)) [SIG CLI]

- DRA: Restricted the length of opaque device configuration parameters. At admission time, Kubernetes enforces a 10KiB size limit. ([#128601](https://github.com/kubernetes/kubernetes/pull/128601), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth,...

- Promoted the `EnvFiles` feature gate to beta and is enabled by default. Additionally, the syntax specification for environment variables has been restricted to a subset of POSIX shell syntax (all variable values must be wrapped in single quotes). ([#134414](https://github.com/kubernetes/kubernetes/pull/134414), [@HirazawaUi](https://github.com/HirazawaUi)) [SIG Node and Testing]

- CoreDNS is only officially supported on Linux at this time.  As such, when kubeadm is used to deploy this component into your kubernetes cluster, it will be restricted (using `nodeSelectors`) to run only on nodes with that operating system. This ensures that in clusters which include Windows nodes, the scheduler will not ever attempt to place CoreDNS pods on these machines, reducing setup latency and enhancing...
