- Kube-apiserver: fixes a 1.27+ regression in watch stability by serving watch requests without a resourceVersion from the watch cache by default, as in <1.27 (disabling the change in #115096 by default). This mitigates the impact of an etcd watch bug (https://github.com/etcd-io/etcd/pull/17555). If the 1.27 change in #115096 to serve these requests from underlying storage is still desired despite the impact on watch stability, it can be re-enabled with a `WatchFromStorageWithoutResourceVersion`...

- Added metric `apiserver_watch_events_total` that can be used to understand the number of watch events in the system. ([#78732](https://github.com/kubernetes/kubernetes/pull/78732), [@mborsz](https://github.com/mborsz))

    * Add `kubectl apply edit-last-applied` subcommand ([#42256](https://github.com/kubernetes/kubernetes/pull/42256), [@shiywang](https://github.com/shiywang))

  * Strategic Merge Patch

    * Reference docs now display the patch type and patch merge key used by `kubectl apply` to merge and identify unique elements in arrays.

* Update Cluster Autoscaler to version 1.3.7. ([#74136](https://github.com/kubernetes/kubernetes/pull/74136), [@jkaniuk](https://github.com/jkaniuk))

### API Change

- Kubernetes 1.23 is now built with go1.19.4. To match behavior of previous Kubernetes 1.23 patch releases:
  - `kube-apiserver` defaults the GOGC setting to 63, to approximate go1.17 garbage collection memory performance in heavily loaded API servers
