- CoreDNS adds readinessProbe which prevents loadbalancing to unready pods, and also allows rolling updates to work as expected. ([#74137](https://github.com/kubernetes/kubernetes/pull/74137), [@rajansandeep](https://github.com/rajansandeep))

  For more information, see [#56348](https://github.com/kubernetes/kubernetes/issues/56348).

*   API server times out after performing a rolling update of the etcd cluster. This issue will be fixed in a future release.

  For more information, see [#47131](https://github.com/kubernetes/kubernetes/issues/47131)

- Revised the logic for DaemonSet rolling update to exclude nodes if scheduling constraints are not met.
