- Fixed a bug in the TopologyManager. Previously, the TopologyManager would only guarantee alignment if container creation was serialized in some way. Alignment is now guaranteed under all scenarios of container creation. ([#87759](https://github.com/kubernetes/kubernetes/pull/87759), [@klueska](https://github.com/klueska)) [SIG Node]

* if kube-apiserver is started with `--storage-backend=etcd2`, the media type `application/json` is used. ([#43122](https://github.com/kubernetes/kubernetes/pull/43122), [@liggitt](https://github.com/liggitt))
* API fields that previously serialized null arrays as `null` and empty arrays as `[]` no longer distinguish between those values and always output `[]` when serializing to JSON. ([#43422](https://github.com/kubernetes/kubernetes/pull/43422), [@liggitt](https://github.com/liggitt))

- Fixed a data race that could occur when a single Go type was serialized to CBOR concurrently for the first time within a program. ([#129170](https://github.com/kubernetes/kubernetes/pull/129170), [@benluddy](https://github.com/benluddy)) [SIG API Machinery]

- Restartable init containers resource in pod autoscaler are now calculated. ([#120001](https://github.com/kubernetes/kubernetes/pull/120001), [@qingwave](https://github.com/qingwave))
- Sidecar termination is now serialized and each sidecar container will receive a `SIGTERM` after all main containers and later starting sidecar containers have terminated. ([#120620](https://github.com/kubernetes/kubernetes/pull/120620), [@tzneal](https://github.com/tzneal))

    replaced with by writing regular Python functions. Using the `tf.function`
    decorator, such functions can be turned into graphs which can be executed
    remotely, serialized, and optimized for performance.
*   Unification of `tf.train.Optimizers` and `tf.keras.Optimizers`. Use
    `tf.keras.Optimizers` for TF2.0. `compute_gradients` is removed as public

class UJSONResponse(JSONResponse):
    """JSON response using the ujson library to serialize data to JSON.

    **Deprecated**: `UJSONResponse` is deprecated. FastAPI now serializes data
    directly to JSON bytes via Pydantic when a return type or response model is
    set, which is faster and doesn't need a custom response class.
