- Removed deprecated `gogo` protocol definitions from `k8s.io/kubelet/pkg/apis/pluginregistration` in favor of `google.golang.org/protobuf`. ([#132773](https://github.com/kubernetes/kubernetes/pull/132773), [@saschagrunert](https://github.com/saschagrunert))

- Client-go: Clients can request protobuf and json and correctly negotiate with the server for JSON for CRD objects, allowing all client libraries to request protobuf if it is available.  If an error occurs negotiating a watch with the server, the error is immediately return by the client `Watch()` method instead of being sent as an `Error` event on...

1.6 will also default to protobuf encoding if using etcd3.  **This change is
irreversible.**  To rollback, you must restore from a backup made before the
protobuf/etcd3 switch, and any changes since the backup will be lost.  As 1.5
does not support protobuf encoding, if you roll back to 1.5 after upgrading to
protobuf you will be forced to restore from backup, and you will lose any changes

- The etcd client has been updated to 3.5.0; `github.com/golang/protobuf`, `google.golang.org/protobuf`, and `google.golang.org/grpc` have been updated to current versions. ([#100488](https://github.com/kubernetes/kubernetes/pull/100488), [@liggitt](https://github.com/liggitt))

* Protobuf serialization does not distinguish between `[]` and `null`.
API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field)
can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6).

- Improved how the API server responds to **list** requests where the response format negotiates to Protobuf. List responses in Protobuf are marshalled one element at the time, drastically reducing memory needed to serve large collections. Streaming list responses can be disabled via the `StreamingCollectionEncodingToProtobuf` feature gate. ([#129407](https://github...

- 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 CBOR), then base64-encoded and stored as a string.
