*  Fix: Don't permit cache iterators to remove entries that are being written.


## Version 4.0.1

_2019-07-10_

 *  Fix: Tolerate null-hostile lists in public API. Lists created with `List.of(...)` don't like it
    when you call `contains(null)` on them!
 *  Fix: Retain binary-compatibility in `okhttp3.internal.HttpHeaders.hasBody()`. Some unscrupulous
    coders call this and we don't want their users to suffer.

        final Collection<FilterFunctionBuilder> list = new ArrayList<>();
        if (functionsLambda != null) {
            functionsLambda.callback((cqLambda, scoreFunctionBuilder) -> {
                WebConfigCQ cf = new WebConfigCQ();
                cqLambda.callback(cf);
                list.add(new FilterFunctionBuilder(cf.getQuery(), scoreFunctionBuilder));
            });
        }

    * Large refactor, improvement, and simplification of param extraction from *path operations*.
    * Fix/add support for list *query parameters* with list defaults. New documentation: [Query parameter list / multiple values with defaults](https://fastapi.tiangolo.com/tutorial/query-params-str-validations/#query-parameter-list-multiple-values-with-defaults).

`response_model`에 선언함으로써 **FastAPI**가 이를 처리하도록 하고, 타입 어노테이션과 에디터 및 다른 도구의 도움에는 영향을 미치지 않도록 설정합니다.

### `HeroPublic`으로 Heroes 조회하기

이전과 동일하게 `Hero`를 **조회**할 수 있습니다. 이번에도 `response_model=list[HeroPublic]`을 사용하여 데이터가 올바르게 검증되고 직렬화되도록 보장합니다.
