* Kube-Proxy now defaults to an iptables-based proxy. If the --proxy-mode flag is
specified while starting kube-proxy (‘userspace’ or ‘iptables’), the flag value
will be respected. If the flag value is not specified, the kube-proxy respects
the Node object annotation: ‘net.beta.kubernetes.io/proxy-mode’. If the
annotation is not specified, then ‘iptables’ mode is the default. If kube-proxy

Run more verbose output (slave JVM parameters, etc.).

- CPU limits are now respected for Windows containers. If a node is over-provisioned, no weighting is used, only limits are respected. ([#86101](https://github.com/kubernetes/kubernetes/pull/86101), [@PatrickLang](https://github.com/PatrickLang)) [SIG Node, Testing and Windows]
