* Update Calico version to v2.6.6 ([#58482](https://github.com/kubernetes/kubernetes/pull/58482), [@tmjd](https://github.com/tmjd))
* Detach and clear bad disk URI ([#58345](https://github.com/kubernetes/kubernetes/pull/58345), [@rootfs](https://github.com/rootfs))

credentials have not been used in the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year), **and** are referenced from the `.secrets` list of a ServiceAccount object, **and**  are not referenced from pods. This label causes the authentication layer to reject use of the credentials. After being labeled as invalid, if the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year) passes without the credential being used, the secret...

- When specifying an invalid value for a label, it was not always clear which label the value was specified for. Starting with this release, the label's key is included in such error messages, which makes debugging easier. ([#77144](https://github.com/kubernetes/kubernetes/pull/77144), [@kenegozi](https://github.com/kenegozi))...

- Fixed a bug in the scheduler that could cause the scheduler to go to an infinite loop when all nodes in a zone are removed. ([#69758](https://github.com/kubernetes/kubernetes/pull/69758), [@bsalamat](https://github.com/bsalamat))
- Clear pod binding cache on bind error to make sure stale pod binding cache will not be used. ([#71212](https://github.com/kubernetes/kubernetes/pull/71212), [@cofyc](https://github.com/cofyc))

- Certain fields on  Service objects will be automatically cleared when changing the service's `type` to a mode that does not need those fields.  For example, changing from type=LoadBalancer to type=ClusterIP will clear the NodePort assignments, rather than forcing the user to clear them.

- kubeadm: Added better handling of errors during unmount when calling `kubeadm reset`. When failing to unmount directories under `/var/run/kubelet`, kubeadm will now throw an error instead of showing a warning and continuing to clean up said directory. In such situations, it is better for you to inspect the problem and resolve it manually. Then, you can call `kubeadm reset` again to complete the cleanup.

* Improved messages user gets during and after volume resizing is done, providing a clear message to the user explaining what to do when resizing is finished. ([#58415](https://github.com/kubernetes/kubernetes/pull/58415), [@gnufied](https://github.com/gnufied))

* apply: fix detection of non-dry-run enabled servers ([#71854](https://github.com/kubernetes/kubernetes/pull/71854), [@apelisse](https://github.com/apelisse))
* Clear UDP conntrack entry on endpoint changes when using nodeport  ([#71573](https://github.com/kubernetes/kubernetes/pull/71573), [@JacobTanenbaum](https://github.com/JacobTanenbaum))

* kubeadm: clean up exited containers and network checkpoints ([#43836](https://github.com/kubernetes/kubernetes/pull/43836), [@yujuhong](https://github.com/yujuhong))
