* Authorization sets `authorization.k8s.io/decision` and `authorization.k8s.io/reason` annotations with the authorization decision ("allow" or "forbid") and a human-readable description of why the decision was made (for example, RBAC includes the name of the role/binding/subject which allowed a request).

* Support multiple scale sets in Azure cloud provider. ([#57543](https://github.com/kubernetes/kubernetes/pull/57543), [@feiskyer](https://github.com/feiskyer))

* Support LoadBalancer for Azure Virtual Machine Scale Sets ([#57131](https://github.com/kubernetes/kubernetes/pull/57131), [@feiskyer](https://github.com/feiskyer))

*   A new service annotation `service.beta.kubernetes.io/azure-dns-label-name` now sets the Azure DNS label for a public IP address. ([#47849](https://github.com/kubernetes/kubernetes/pull/47849),[ @tomerf](https://github.com/tomerf))

## Changelog since v1.23.6

## Changes by Kind

### API Change

- Exposes and sets a default timeout for the SubjectAccessReview client for DelegatingAuthorizationOptions ([#96153](https://github.com/kubernetes/kubernetes/pull/96153), [@p0lyn0mial](https://github.com/p0lyn0mial)) [SIG API Machinery and Cloud Provider]

- Exposes and sets a default timeout for the SubjectAccessReview client for DelegatingAuthorizationOptions ([#96152](https://github.com/kubernetes/kubernetes/pull/96152), [@p0lyn0mial](https://github.com/p0lyn0mial)) [SIG API Machinery and Cloud Provider]

* Change `kubeadm create token` to default to the group that almost everyone will want to use.  The group is system:bootstrappers:kubeadm:default-node-token and is the group that kubeadm sets up, via an RBAC binding, for auto-approval (system:certificates.k8s.io:certificatesigningrequests:nodeclient). ([#53512](https://github.com/kubernetes/kubernetes/pull/53512), [@jbeda](https://github.com/jbeda))

### Other (Cleanup or Flake)

- Kube-apiserver: sets an upper-bound on the lifetime of idle keep-alive connections and time to read the headers of incoming requests ([#103958](https://github.com/kubernetes/kubernetes/pull/103958), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Node]

- Updated the Partitionable Devices feature to support referencing counter sets across ResourceSlices within the same resource pool. Devices from incomplete pools were no longer considered for allocation. This change introduced backwards-incompatible updates to the alpha feature, requiring any ResourceSlices using it to be removed...

- Changed how the API server handles updates to `.spec.defaultBackend` of Ingress objects.
