- API requests to deprecated versions now receive a warning header in the API response, and cause a metric indicating use of a deprecated API to be published:
  - `kubectl` outputs warnings to stderr, and accepts a `--warnings-as-errors` option to treat warnings as fatal errors

- Graduated the `LegacyServiceAccountTokenTracking` feature gate to GA. The usage of auto-generated secret-based service account token now produces warnings, and relevant Secrets are labeled with a last-used timestamp (label key `kubernetes.io/legacy-token-last-used`). ([#117591](https://github.com/kubernetes/kubernetes/pull/117591), [@zshihang](https://github.com/zshihang)) [SIG API Machinery, Auth...

- Added warnings when creating headless service with set `loadBalancerIP`,`externalIPs` and/or `SessionAffinity`. ([#132214](https://github.com/kubernetes/kubernetes/pull/132214), [@Peac36](https://github.com/Peac36))

- Kubeadm: improve the strict parsing of user YAML/JSON configuration files. Next to printing warnings for unknown and duplicate fields (current state), also print warnings for fields with incorrect case sensitivity - e.g. `controlPlaneEndpoint` (valid), `ControlPlaneEndpoint` (invalid). Instead of only printing warnings during `init` and `join` also print warnings when downloading the ClusterConfiguration, KubeletConfiguration or KubeProxyConfiguration objects from the cluster....

- Added warnings for overlap paths in ConfigMap, Secret, DownwardAPI, Projected. Added warning for cases when ProjectedVolume with sources is provided. ([#121968](https://github.com/kubernetes/kubernetes/pull/121968), [@Peac36](https://github.com/Peac36))

- Validation rules for Custom Resource Definitions can be written in the [CEL expression language](https://gith...

- Kubeadm: perform pre-flight validation on host/node name upon `kubeadm init` and `kubeadm join`, showing warnings on non-compliant names ([#99194](https://github.com/kubernetes/kubernetes/pull/99194), [@pacoxu](https://github.com/pacoxu))

  - The `--experimental-encryption-provider-config` flag is deprecated in favor of `--encryption-provider-config`. The old flag is accepted with a warning but will be removed in 1.14. ([#71206](https://github.com/kubernetes/kubernetes/pull/71206),...

has some fixed limit (including persistent volume counts on cloud nodes, exclusive CPU cores, or unique hardware devices) could trigger the failure. While this behavior is correct it reduces the throughput of pod execution and creates user-visible warnings - [future versions of Kubernetes will minimize the likelihood users see pod failures due to this issue](https://github.com/kubernetes/kubernetes/issues/106884). In general, any automation that creates pods [must take Kubelet rejections into acco...
