- Fix: skip `instance not found` when decoupling VMSSs from LB ([#105666](https://github.com/kubernetes/kubernetes/pull/105666), [@nilo19](https://github.com/nilo19))
- Fix: skip case sensitivity when checking Azure NSG rules. ([#104384](https://github.com/kubernetes/kubernetes/pull/104384), [@feiskyer](https://github.com/feiskyer))

- 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...
