* Ensure OpenAPI normalizers properly expose the date format
* Add source maps for Swagger UI
* Improve error message when filter class is not imported
* Add missing autowiring alias for `Pagination`
* Doctrine: ensure that `EntityManagerInterface` is used in data providers

## 2.4.6

* Fix resource inheritance handling
* Fix BC break in `AbstractItemNormalizer` introduced in 2.4
* Fix serialization when using interface as resource
* Basic compatibility with Symfony 4.3

## 2.4.3

* Doctrine: allow autowiring of filter classes
* Doctrine: don't use `fetchJoinCollection` on `Paginator` when not needed
* Doctrine: fix a BC break in `OrderFilter`
* GraphQL: input objects aren't nullable anymore (compliance with the Relay spec)
* Cache: Remove some useless purges
* Mercure: publish to Mercure using the default response format
* Mercure: use the Serializer context
* OpenAPI: fix documentation of the `PropertyFilter`
* OpenAPI: fix generation of the `servers` block (also fixes the compatibility with Postman)
* OpenAPI: skip not readable and not writable properties from the spec
* OpenAPI: add the `id` path parameter for POST item operation
* Serializer: add support for Symfony Serializer's `@SerializedName` metadata
* Metadata: `ApiResource`'s `attributes` property now defaults to `null`, as expected
* Metadata: Fix identifier support when using an interface as resource class
* Metadata: the HTTP method is now always uppercased
* Allow to disable listeners per operation (fix handling of empty request content)

    Previously, empty request content was allowed for any `POST` and `PUT` operations. This was an unsafe assumption which caused [other problems](https://github.com/api-platform/core/issues/2731).

    If you wish to allow empty request content, please add `"deserialize"=false` to the operation's attributes. For example:

    ```php
    <?php
    // api/src/Entity/Book.php

    use ApiPlatform\Core\Annotation\ApiResource;
    use App\Controller\PublishBookAction;

    /**
     * @ApiResource(
     *     itemOperations={
     *         "put_publish"={
     *             "method"="PUT",
     *             "path"="/books/{id}/publish",
     *             "controller"=PublishBookAction::class,
     *             "deserialize"=false,
     *         },
     *     },
     * )
     */
    class Book
    {
    ```

    You may also need to add `"validate"=false` if the controller result is `null` (possibly because you don't need to persist the resource).

* Return the `204` HTTP status code when the output class is set to `null`
* Be more resilient when normalizing non-resource objects
* Replace the `data` request attribute by the return of the data persister
* Fix error message in identifiers extractor
* Improve the bundle's default configuration when using `symfony/symfony` is required
* Fix the use of `MetadataAwareNameConverter` when available (configuring `name_converter: serializer.name_converter.metadata_aware` will now result in a circular reference error)

## 2.4.2

* Fix a dependency injection problem in `FilterEagerLoadingExtension`
* Improve performance by adding a `NoOpScalarNormalizer` handling scalar values

## 2.4.1

* Improve performance of the dev environment and deprecate the `api_platform.metadata_cache` parameter
* Fix a BC break in `SearchFilter`
* Don't send HTTP cache headers for unsuccessful responses

* Preserve manual join in FilterEagerLoadingExtension
* The `elasticsearch` attribute can be disabled resource-wise or per-operation
* The `messenger` attribute can now take the `input` string as a value (`messenger="input"`). This will use a default transformer so that the given `input` is directly sent to the messenger handler.
* The `messenger` attribute can be declared per-operation
* Mercure updates are now published after the Doctrine flush event instead of on `kernel.terminate`, so the Mercure and the Messenger integration can be used together
* Use Symfony's MetadataAwareNameConverter when available
* Change the extension's priorities (`<0`) for improved compatibility with Symfony's autoconfiguration feature. If you have custom extensions we recommend to use positive priorities.
