- Kubeadm: Fixed a regression where the JoinConfiguration.discovery.timeout was no longer respected and the value was always hardcoded to "5m" (5 minutes). ([#125480](https://github.com/kubernetes/kubernetes/pull/125480), [@neolit123](https://github.com/neolit123))
- Kubeadm: Removed support for mounting /etc/pki as an additional Linux system CA location

- Fixed a `v1.28` regression in scheduler: a pod with concurrent events could incorrectly get moved to the unschedulable queue where it could get stuck until the next periodic purging after 5 minutes, if there was no other event for it.

##### Cluster Autoscaler

* Cluster autoscaler is now GA
* Cluster support size is increased to 1000 nodes
* Respect graceful pod termination of up to 10 minutes
* Handle zone stock-outs and failures
* Improve monitoring and error reporting

#### Container Runtime Interface (CRI)

### Other (Cleanup or Flake)

- Volumes are no longer detached from healthy nodes after 6 minutes timeout. 6 minute force-detach timeout is used only for unhealthy nodes (`node.status.conditions["Ready"]!= true`). ([#110721](https://github.com/kubernetes/kubernetes/pull/110721), [@jsafrane](https://github.com/jsafrane))
