* **Validate data**: coming from each request:
    * Generating **automatic errors** returned to the client when the data is invalid.
* **Document** the API using OpenAPI:
    * which is then used by the automatic interactive documentation user interfaces.

This might all sound abstract. Don't worry. You'll see all this in action in the [Tutorial - User Guide](tutorial/index.md){.internal-link target=_blank}.

When you see the automatic docs, you can check that the input model and output model will both have their own JSON Schema:

And both models will be used for the interactive API documentation:

!!! tip
    To declare a query parameter with a type of `list`, like in the example above, you need to explicitly use `Query`, otherwise it would be interpreted as a request body.

The interactive API docs will update accordingly, to allow multiple values:

                The default URL is `/docs`. You can disable it by setting it to `None`.

- Client-go exec credential plugins will pass stdin only when interactive terminal is detected on stdin. This fixes a bug where previously it was checking if **stdout** is an interactive terminal.

    before the response starts. With duplex, request and response bodies are transmitted
    simultaneously. This can be used to implement interactive conversations within a single HTTP
    call.

    Create duplex calls by overriding the new `RequestBody.isDuplex()` method to return true.
