- Fixes a bug at kube-apiserver start where APIService objects for custom resources could be deleted and recreated. ([#118104](https://github.com/kubernetes/kubernetes/pull/118104), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

- NONE ([#124326](https://github.com/kubernetes/kubernetes/pull/124326), [@ritazh](https://github.com/ritazh)) [SIG Auth]
- OpenAPI V2 will no longer publish aggregated apiserver OpenAPI for group-versions not matching the APIService specified group version ([#123625](https://github.com/kubernetes/kubernetes/pull/123625), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery and Testing]

## Dependencies

### Added

- OpenAPI V2 will no longer publish aggregated API server OpenAPI for group versions that do not match the APIService specified group version. ([#123570](https://github.com/kubernetes/kubernetes/pull/123570), [@Jefftree](https://github.com/Jefftree))

There is no mitigation from this issue.  Cluster admins should take care to secure aggregated API servers and should not grant access to mutate `APIService`s to untrusted parties.

**Affected Versions**:
  - kube-apiserver v1.25.0
  - kube-apiserver v1.24.0 - v1.24.4
  - kube-apiserver v1.23.0 - v1.23.10
  - kube-apiserver v1.22.0 - v1.22.14

* Make logdump support kubemark and support gke with 'use_custom_instance_list' ([#51834](https://github.com/kubernetes/kubernetes/pull/51834), [@shyamjvs](https://github.com/shyamjvs))
* Fixes an issue with APIService auto-registration affecting rolling HA apiserver restarts that add or remove API groups being served. ([#51921](https://github.com/kubernetes/kubernetes/pull/51921), [@liggitt](https://github.com/liggitt))

- Fixed the sample-apiserver so that its BanFlunder admission plugin can be used. ([#68417](https://github.com/kubernetes/kubernetes/pull/68417), [@MikeSpreitzer](https://github.com/MikeSpreitzer))
- APIService availability related to networking glitches are corrected faster ([#68678](https://github.com/kubernetes/kubernetes/pull/68678), [@deads2k](https://github.com/deads2k))

* kube-apiserver: requests to endpoints handled by unavailable extension API servers (as indicated by an `Available` condition of `false` in the registered APIService) now return `503` errors instead of `404` errors. ([#58070](https://github.com/kubernetes/kubernetes/pull/58070), [@weekface](https://github.com/weekface))

[alpha] Support ipvs mode for kube-proxy([#46580](https://github.com/kubernetes/kubernetes/pull/46580), [@haibinxie](https://github.com/haibinxie))
