- Implemented API streaming for the `watch-cache`
  
  When `sendInitialEvents` `ListOption` is set together with `watch=true`, it begins the watch stream with synthetic init events followed by a synthetic "Bookmark" after which the server continues streaming events. ([#110960](https://github.com/kubernetes/kubernetes/pull/110960), [@p0lyn0mial](https://github.com/p0lyn0mial))
- Introduced API for streaming.
  

- Implemented API for streaming for the `etcd` store implementation.

- Removed the `kubernetes.io/initial-events-list-blueprint` annotation from the synthetic "Bookmark" event in watch stream requests. ([#132326](https://github.com/kubernetes/kubernetes/pull/132326), [@p0lyn0mial](https://github.com/p0lyn0mial))

- The `EndpointSlice` IP validation now matches `Endpoints` IP validation. ([#101084](https://github.com/kubernetes/kubernetes/pull/101084), [@robscott](https://github.com/robscott))
- The `kube-apiserver` now reports the synthetic verb when logging requests, better explaining the user intent and matching what is reported in the metrics. ([#102934](https://github.com/kubernetes/kubernetes/pull/102934), [@lavalamp](https://github.com/lavalamp))

- The synthetic "Bookmark" event for the watch stream requests will now include a new annotation: `kubernetes.io/initial-events-list-blueprint`. THe annotation contains an empty, versioned list that is encoded in the requested format (such as protobuf, JSON, or...
