  - Aggregated discovery requests can now timeout. Aggregated API servers must complete discovery calls within 5 seconds (other requests can take longer). Use the feature gate `EnableAggregatedDiscoveryTimeout=false` to temporarily revert behavior to the previous 30 second timeout if required (the temporary...

### **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.

* 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.
