### **Cluster Lifecycle**

*   You must either specify the `--discovery-token-ca-cert-hash` flag to `kubeadm join`, or opt out of the CA pinning feature using `--discovery-token-unsafe-skip-ca-verification`.
*   The default `auto-detect` behavior of the kubelet's `--cloud-provider` flag is removed.

 * <p>The implementation uses an executor service for concurrent processing of file operations and maintains
 * a cache of URLs to be deleted for batch processing. It handles redirect following and child URL discovery
 * during the crawling process.</p>

* The kube-apiserver discovery APIs (for example, `/apis`) return information about the API groups being served, and can change dynamically.
During server startup, prior to the server reporting healthy (via `/healthz`), not all API groups may be reported.
Wait for the server to report healthy (via `/healthz`) before depending on the information provided by the discovery APIs.

- Fixed cluster autoscaler addon permissions so it can access batch/job. ([#69858](https://github.com/kubernetes/kubernetes/pull/69858), [@losipiuk](https://github.com/losipiuk))

### API Server Aggregator
* Rename kubernetes-discovery to kube-aggregator ([#39619](https://github.com/kubernetes/kubernetes/pull/39619), [@deads2k](https://github.com/deads2k))
* Fix connection upgrades through kubernetes-discovery ([#38724](https://github.com/kubernetes/kubernetes/pull/38724), [@deads2k](https://github.com/deads2k))

#### Generic API Server

* FC volume plugin: Support WWID for volume identifier ([#48741](https://github.com/kubernetes/kubernetes/pull/48741), [@mtanino](https://github.com/mtanino))
* kubeadm: added enhanced TLS validation for token-based discovery in `kubeadm join` using a new `--discovery-token-ca-cert-hash` flag. ([#49520](https://github.com/kubernetes/kubernetes/pull/49520), [@mattmoyer](https://github.com/mattmoyer))
