- Added a kubelet metric `container_aligned_compute_resources_count`  to report the count of containers getting aligned compute resources. ([#127155](https://github.com/kubernetes/kubernetes/pull/127155), [@ffromani](https://github.com/ffromani)) [SIG Node and Testing]

- `kubeadm`: will now allow deploying a kubelet that is 3 versions older than the version of `kubeadm` (N-3). This aligns with the recent change made by SIG Architecture that extends the support skew between the control plane and kubelets. Tolerate this new kubelet skew for the commands `init`, `join` and `upgrade`. Note that if the `kubeadm` user applies a control plane...

* Move hardPodAffinitySymmetricWeight to scheduler policy config ([#44159](https://github.com/kubernetes/kubernetes/pull/44159), [@wanghaoran1988](https://github.com/wanghaoran1988))

* Align Extender's validation with prioritizers. ([#45091](https://github.com/kubernetes/kubernetes/pull/45091), [@k82cn](https://github.com/k82cn))

- Extended the kube-apiserver loopback client certificate validity to 14 months to align with the updated Kubernetes support lifecycle. ([#130047](https://github.com/kubernetes/kubernetes/pull/130047), [@HirazawaUi](https://github.com/HirazawaUi)) [SIG API Machinery and Auth]

* Remove unnecessary metrics (http/process/go) from being exposed by etcd-version-monitor ([#41807](https://github.com/kubernetes/kubernetes/pull/41807), [@shyamjvs](https://github.com/shyamjvs))
* Align the hyperkube image to support running binaries at /usr/local/bin/ like the other server images ([#41017](https://github.com/kubernetes/kubernetes/pull/41017), [@luxas](https://github.com/luxas))

- `DynamicKubeletConfig` feature gate has been removed from the API server.
  Dynamic kubelet reconfiguration now can't be used even when older nodes are still
  attempting to rely on it. This is aligned with the Kubernetes version skew policy.
   ([#112643](https://github.com/kubernetes/kubernetes/pull/112643), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev))

    *   Added a new field, `filter_parallelization`, to `tf.data.experimental.OptimizationOptions`. If it is set to `True`, tf.data...

- XFS-filesystems are now force-formatted (option `-f`) in order to avoid problems being formatted due to detection of magic super-blocks. This aligns with the behaviour of formatting of ext3/4 filesystems. ([#104923](https://github.com/kubernetes/kubernetes/pull/104923), [@davidkarlsen](https://github.com/davidkarlsen))
