- The deprecated flag --experimental-kustomize is now removed from kubeadm commands. Use --experimental-patches instead, which was introduced in 1.19. Migration information available in --help description for --experimental-patches. ([#94871](https://github.com/kubernetes/kubernetes/pull/94871), [@neolit123](https://github.com/neolit123))

### (No, really, you MUST read this before you upgrade)

- Kubeadm: remove the deprecated flag `--experimental-patches` for the `init|join|upgrade` commands. The flag `--patches` is no longer allowed in a mixture with the flag `--config`. Please use the kubeadm configuration for setting patches for a node using `{Init|Join}Configuration.patches`.
