- The following features...

    This simple option dramatically changes the behavior of the request body and of the entire
    call.

    The `RequestBody.writeTo()` method may now retain a reference to the provided sink and
    hand it off to another thread to write to it after `writeTo` returns.

    The `EventListener` may now see requests and responses interleaved in ways not previously

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

### Concurrent Burgers { #concurrent-burgers }

You go with your crush to get fast food, you stand in line while the cashier takes the orders from the people in front of you. 😍

- EndpointSlices with Pod referencing Nodes that don't exist couldn't be created or updated. The behavior on the EndpointSlice controller has been modified to update the EndpointSlice without the Pods that reference non-existing Nodes and keep retrying until all Pods reference existing Nodes. However, if `service.Spec.PublishNotReadyAddresses` is set, all the Pods are published without retrying. Fixed EndpointSlices metrics to reflect correctly the number of desired EndpointSlices when no...
