## Changelog since v1.32.11

## Changes by Kind

### Feature

- Kubeadm: when patching a Node object do not exit early on unknown (non-allowlisted) API errors. Instead, always retry within the duration of the polling for getting and patching a Node object. ([#136069](https://github.com/kubernetes/kubernetes/pull/136069), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubernetes is now built using Go 1.24.12 ([#13646

 in your manifest. An object with a spec.selector value that does not match the labels in
 its spec.template is invalid.

 - Selector mutation is disabled for all kinds in the
 app/v1beta2 group version, because the controllers in the workloads API do not handle
 selector mutation in
 a consistent way. This restriction may be lifted in the future, but
 it is likely that that selectors will remain immutable after the move to v1.

* Add CLUSTER_SIGNING_DURATION environment variable to cluster ([#52497](https://github.com/kubernetes/kubernetes/pull/52497), [@jcbsmpsn](https://github.com/jcbsmpsn))
    * configuration scripts to allow configuration of signing duration of
    * certificates issued via the Certificate Signing Request API.

- Fix /readyz to return error immediately after a shutdown is initiated, before the --shutdown-delay-duration has elapsed. ([#88911](https://github.com/kubernetes/kubernetes/pull/88911), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]

- The new feature gate "SidecarContainers" is now available. This feature introduces sidecar containers, a new type of init container that starts before other containers but remains running for the full duration of the pod's lifecycle and will not block pod termination.
