- 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`...

## Notable Features

### Stable

- The kube-apiserver’s `watch` can now be enabled for events using the `--watch-cache-sizes` flag. ([#74321](https://github.com/kubernetes/kubernetes/pull/74321), [@yastij](https://github.com/yastij))

### Beta

## Removed and deprecated metrics

### Removed metrics

- `reflector_items_per_list`
- `reflector_items_per_watch`
- `reflector_last_resource_version`
- `reflector_list_duration_seconds`
- `reflector_lists_total`
- `reflector_short_watches_total`
- `reflector_watch_duration_seconds`
- `reflector_watches_total`

### Deprecated metrics

- 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))

Renamed FeatureGate RequestManagement to APIPriorityAndFairness....

- The watch API endpoints prefixed with `/watch` are deprecated and will be removed in a future release. These standard method for watching resources (supported since v1.0) is to use the list API endpoints with a `?watch=true` parameter. All client-go clients have used the parameter method since v1.6.0. ([#65147](https://github.com/kubernetes/kubernetes/pull/65147),...

  - *apiserver_cache_list_fetched_objects_total*: Counter of objects read from watch cache in the course of serving a LIST request, broken down by resource_prefix and index_name
  - *apiserver_cache_list_evaluated_objects_total*: Counter of objects tested in the course of serving a LIST request from watch cache, broken down by resource_prefix

- Removed deprecated kubectl.kubernetes.io/default-logs-container support ([#109254](https://github.com/kubernetes/kubernetes/pull/109254), [@pacoxu](https://github.com/pacoxu))
- Renamed `apiserver_watch_cache_watch_cache_initializations_total` to `apiserver_watch_cache_initializations_total` ([#109579](https://github.com/kubernetes/kubernetes/pull/109579), [@logicalhan](https://github.com/logicalhan))
