- 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...

- Optimize EC2 DescribeInstances API calls in aws cloud provider library by querying instance ID instead of EC2 filters when possible ([#78140](https://github.com/kubernetes/kubernetes/pull/78140), [@zhan849](https://github.com/zhan849))

- 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.
