optional. If the value is not provided i.e., the command looks like `wait --for=jsonpath='{expression}'`
  then the wait condition is interpreted as matched when the expression returns
  *any* single JSON value like object or a literal. ([#118160](https://github.com/kubernetes/kubernetes/pull/118160), [@minherz](https://github.com/minherz))

* Removed always pull policy from the template for ingress on CDK. ([#61598](https://github.com/kubernetes/kubernetes/pull/61598), [@hyperbolic2346](https://github.com/hyperbolic2346))

### Bug or Regression

*   TF SavedModel:
    *   Custom gradients are now saved by default. See
        `tf.saved_model.SaveOptions` to disable this.
    *   The saved_model_cli's `--input_examples` inputs are now restricted to
        python literals to avoid code injection.
*   XLA:
    *   Add a new API that allows custom call functions to signal errors. The
        old API will be deprecated in a future release. See

- Openapi-controller: remove the trailing `1` character literal from the rate limiting metric `APIServiceOpenAPIAggregationControllerQueue1` and rename it to `open_api_aggregation_controller` to adhere to Prometheus best practices.
