- New flag `--show-hidden-metrics-for-version` in kube-proxy, kubelet, kube-controller-manager, and kube-scheduler can be used to show all hidden metrics that are deprecated in the previous minor release.

- New flag `--show-hidden-metrics-for-version` in kube-apiserver can be used to show all hidden metrics that deprecated in the previous minor release. ([#84292](https://github.com/kubernetes/kubernetes/pull/84292), [@RainbowMango](https://github.com/RainbowMango))

- CCM server will not listen insecurely if secure port is specified ([#68982](https://github.com/kubernetes/kubernetes/pull/68982), [@aruneli](https://github.com/aruneli))

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions. (...

cluster-internal resources installed by kubeadm will be overwritten when upgrading from v1.6 to v1.7. ([#47081](https://github.com/kubernetes/kubernetes/pull/47081), [@luxas](https://github.com/luxas))

* kubeadm deb/rpm packages: cAdvisor doesn't listen on `0.0.0.0:4194` without authentication/authorization because of the possible information leakage. The cAdvisor API can still be accessed via `https://{node-ip}:10250/stats/`, though. ([kubernetes/release#356](https://github.com/kubernetes/release/pull/356),...

- Added support to the kube-proxy nodePortAddresses / --nodeport-addresses option to
  accept the value "primary", meaning to only listen for NodePort connections
  on the node's primary IPv4 and/or IPv6 address (according to the Node object).
  This is strongly recommended, if you were not previously using
  --nodeport-addresses, to avoid surprising behavior.

* Allow kube- and cloud-controller-manager to listen on ports up to 65535. ([#65860](https://github.com/kubernetes/kubernetes/pull/65860), [@sttts](https://github.com/sttts))
* Allow kube-scheduler to listen on ports up to 65535. ([#65833](https://github.com/kubernetes/kubernetes/pull/65833), [@sttts](https://github.com/sttts))

- Kubernetes now includes an alpha field, `AllowWatchBookmarks`, in ListOptions for requesting the watching of bookmarks from apiserver. The implementation in apiserver is hidden behind the feature gate `WatchBookmark`. ([#74074](https://github.com/kubernetes/kubernetes/pull/74074), [@wojtek-t](https://github.com/wojtek-t))

### Staging Repositories

   ([#122493](https://github.com/kubernetes/kubernetes/pull/122493), [@mengjiao-liu](https://github.com/mengjiao-liu))
- Fixed the deprecated version for `pod_scheduling_duration_seconds` that caused the metric to be hidden by default in `1.29`.
