* enforces  kubeadm  upgrading kubernetes from the same major and minor versions as the kubeadm binary.
* Bugfix allowing use of IP-aliases with custom-mode network in GCE setup scripts. ([#62172](https://github.com/kubernetes/kubernetes/pull/62172), [@shyamjvs](https://github.com/shyamjvs))

  - hack/lib/util.sh: some bash cleanups
    
    - switched one spot to use kube::logging
    - make kube::util::find-binary return an error when it doesn't find
      anything so that hack scripts fail fast instead of with '' binary not
      found errors.
    - this required deleting some genfeddoc stuff. the binary no longer
      exists in k/k repo since we removed federation/, and I don't see it

/// tip | Tipp

- Integration testing now takes periodic Prometheus scrapes from the etcd server.

Invocations using `kubectl alpha debug` are now deprecated and will be removed in a subsequent release. Update your scripts to use `kubectl debug` instead of `kubectl alpha debug`!

### Other (Cleanup or Flake)

- Bump distroless-iptables to 0.2.8 based on Go 1.20.11 ([#121975](https://github.com/kubernetes/kubernetes/pull/121975), [@cpanato](https://github.com/cpanato)) [SIG Testing]
- Makefile and scripts now respect GOTOOLCHAIN and otherwise ensure ./.go-version is used ([#122076](https://github.com/kubernetes/kubernetes/pull/122076), [@BenTheElder](https://github.com/BenTheElder)) [SIG Release and Testing]

## Dependencies

* `cluster/kube-up.sh` now provisions a Kubelet config file for GCE via the metadata server. This file is installed by the corresponding GCE init scripts. ([#62183](https://github.com/kubernetes/kubernetes/pull/62183), [@mtaufen](https://github.com/mtaufen))

- Updated defaultbackend image to 1.5. Users should concentrate on updating scripts to the new version. ([#69120](https://github.com/kubernetes/kubernetes/pull/69120), [@aledbf](https://github.com/aledbf))

### Other notable changes

* federation: fix dns provider initialization issues ([#27252](https://github.com/kubernetes/kubernetes/pull/27252), [@mfanjie](https://github.com/mfanjie))
* Updating federation up scripts to work in non e2e setup ([#27260](https://github.com/kubernetes/kubernetes/pull/27260), [@nikhiljindal](https://github.com/nikhiljindal))

    To address this, the new debian-hyperkube-base image (v1.1.0) uses the
    debian-iptables base image (v12.1.0), which includes iptables-wrapper, a
    script used to determine the correct iptables mode to run in. ([#92493](https://github.com/kubernetes/kubernetes/pull/92493), [@justaugustus](https://github.com/justaugustus)) [SIG Cluster Lifecycle and Release]
