If a package has imports, the imported packages are initialized
before initializing the package itself. If multiple packages import
a package, the imported package will be initialized only once.
The importing of packages, by construction, guarantees that there
can be no cyclic initialization dependencies.

PatchOptions respectively. Signatures of Delete and DeleteCollection methods now accept DeleteOptions by value instead of by reference. Generated clientsets with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new APIs. The deprecated packages will be removed in the 1.21 release. A tool is available at http://sigs.k8s.io/clientgofix to rewrite method invocations to the new signatures.

- The following deprecated metrics are removed, please...

  
    A previous release built hyperkube using the debian-hyperkube-base@v1.0.0,
    which was updated to address a CVE in the CNI plugins.
    
    A side-effect of using this new image was that the networking packages
    (namely `iptables`) drifted from the versions used in the kube-proxy images.
  
    The following issues were filed on kube-proxy failures when using hyperkube:

#### Generic API Server
* Move pkg/api/rest into genericapiserver ([#39948](https://github.com/kubernetes/kubernetes/pull/39948), [@sttts](https://github.com/sttts))
* Move non-generic apiserver code out of the generic packages ([#38191](https://github.com/kubernetes/kubernetes/pull/38191), [@sttts](https://github.com/sttts))

- Made `apiextensions-apiserver` binary linking static (also affects the deb and rpm packages). ([#114226](https://github.com/kubernetes/kubernetes/pull/114226), [@saschagrunert](https://github.com/saschagrunert))
- Made `kube-aggregator` binary linking static (also affects the deb and rpm packages). ([#114227](https://github.com/kubernetes/kubernetes/pull/114227), [@saschagrunert](https://github.com/saschagrunert))

  `v1.28` server with the beta feature and API enabled. ([#120018](https://github.com/kubernetes/kubernetes/pull/120018), [@liggitt](https://github.com/liggitt))
- `client-go`: `k8s.io/client-go/tools` events and record packages now have new APIs for specifying a context and logger. ([#120729](https://github.com/kubernetes/kubernetes/pull/120729), [@pohly](https://github.com/pohly))

- Added functionality to enable br_netfilter and ip_forward for debian packages to improve kubeadm support for CRI runtime besides Docker.  ([#70152](https://github.com/kubernetes/kubernetes/pull/70152), [@ashwanikhemani](https://github.com/ashwanikhemani))

Modifications to 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))
