## Changelog since v1.10.5

### Action Required

- Missing directories listed in a user's PATH are no longer considered errors and are instead logged by the `kubectl plugin list` command when listing available plugins. ([#73542](https://github.com/kubernetes/kubernetes/pull/73542), [@juanvallejo](https://github.com/juanvallejo))

  - A `create` or `update` API request with duplicate items in a keyed list no longer wipes out managedFields. Examples include env var entries with the same name, or port entries with the same containerPort in a pod spec.
  - A server-side apply request that makes unrelated changes to an object which has duplicate items in a keyed list no longer fails, and leaves the existing duplicate items as-is.

## Changelog since v1.11.0

### Action Required

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions.

* Allow kube- and cloud-controller-manager to listen on ports up to 65535. ([#65860](https://github.com/kubernetes/kubernetes/pull/65860), [@sttts](https://github.com/sttts))
* Allow kube-scheduler to listen on ports up to 65535. ([#65833](https://github.com/kubernetes/kubernetes/pull/65833), [@sttts](https://github.com/sttts))

- QueueingHint implementation for NodeUnschedulable is reverted because we found potential scenarios where events that make Pods schedulable could be missed. ([#122288](https://github.com/kubernetes/kubernetes/pull/122288), [@sanposhiho](https://github.com/sanposhiho))...

// The method Len returns the number of elements in the linked list l.

- Kubeadm: when applying the overrides provided by the user using "extraArgs", do not sort the resulted list of arguments alpha-numerically. Instead, only sort the list of default arguments and keep the list of overrides unsorted. This allows finer control for flags which have an order that matters, such as, "--service-account-issuer" for kube-apiserver. ([#135852](https://github.com/kubernetes/kubernetes/pull/135852),...
