- The alpha `Initializers` admission plugin is no longer enabled by default. This matches the off-by-default behavior of the alpha API which drives initializer behavior. ([#66039](https://github.com/kubernetes/kubernetes/pull/66039), [@liggitt](https://github.com/liggitt))

* Fix a scalability issue where high rates of event writes degraded etcd performance. ([#64539](https://github.com/kubernetes/kubernetes/pull/64539), [@ccding](https://github.com/ccding))

* Prevent `resourceVersion` updates for custom resources on no-op writes. ([#67562](https://github.com/kubernetes/kubernetes/pull/67562), [@nikhita](https://github.com/nikhita))

- Added support for CRD conversion webhook ([#67006](https://github.com/kubernetes/kubernetes/pull/67006), [@mbohlool](https://github.com/mbohlool))

- Fixes creationTimestamp: null causing unnecessary writes to etcd ([#116865](https://github.com/kubernetes/kubernetes/pull/116865), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery and Testing]

#### Scalability

* The HorizontalPodAutoscaler controller will now only send updates when it has new status information, reducing the number of writes caused by the controller. ([#47078](https://github.com/kubernetes/kubernetes/pull/47078), [@DirectXMan12](https://github.com/DirectXMan12))
