## Changes by Kind

### Feature

* Fix session affinity issue with external load balancer traffic when ExternalTrafficPolicy=Local. ([#55519](https://github.com/kubernetes/kubernetes/pull/55519), [@MrHohn](https://github.com/MrHohn))
* Addon manager supports HA masters. ([#55782](https://github.com/kubernetes/kubernetes/pull/55782), [@x13n](https://github.com/x13n))

- The new flag `--chunk-size=SIZE` has been added to `kubectl describe`. This flag may be used to alter the number of items or disable this feature when `0` is passed. ([#101171](https://github.com/kubernetes/ku...

- The `client-go` dynamic client sets the header `Content-Type: application/json` by default ([#104327](https://github.com/kubernetes/kubernetes/pull/104327), [@sxllwx](https://github.com/sxllwx))
- The `kube-Proxy` now correctly filters out unready endpoints for Services with Topology. ([#106507](https://github.com/kubernetes/kubernetes/pull/106507), [@robscott](https://github.com/robscott))

- Informer/reflector callers can now catch and unwrap specific API errors by type. ([#110076](https://github.com/kubernetes/kubernetes/pull/110076), [@karlkfi](https://github.com/karlkfi))

DockerValidor and ServiceCheck for the `docker` service from kubeadm preflight. Docker is no longer special cased during host validation and ideally this task should be done in the now external cri-dockerd project where the importance of the compatibility matters. Use `crictl` for all communication with CRI sockets for actions like pulling images and obtaining a list of running containers instead of using the docker CLI in the case of Docker. ([#107317](https://github.com/kubernetes/kubernetes/pull/107317),...

- When a PreFilterResult filters out certain Nodes, the scheduling framework now categorizes them as rejected via `UnschedulableAndUnresolvable`. Consequently, these nodes are excluded from the candidates for the preemption process. Additionally, this update corrects how the scheduling...

`admin.conf` is now bound to a new RBAC Group `kubeadm:cluster-admins` that has `cluster-admin` `ClusterRole` access. The User in `super-admin.conf` is now bound to the `system:masters` built-in super-powers / break-glass Group that can bypass RBAC. Before this change, the default `admin.conf` was bound to `system:masters` Group, which was undesired. Executing `kubeadm init phase kubeconfig all` or just `kubeadm init` will now generate the new `super-admin.conf` file. The cluster admin can then decide...

- API Server tracing now includes the latency of authorization, priorityandfairness, impersonation, audit, and authentication filters. ([#113217](https://github.com/kubernetes/kubernetes/pull/113217), [@dashpole](https://github.com/dashpole))
