TwigBundle ---------- * Deprecated `twig.exception_controller` configuration option. If you were not using this option previously, set it to `null`: After: ```yaml twig: exception_controller: null ``` If you were using this option previously, set it to `null` and use `framework.error_controller` instead: Before: ```yaml twig: exception_controller: 'App\Controller\MyExceptionController' ``` After: ```yaml twig: exception_controller: null framework: error_controller: 'App\Controller\MyExceptionController' ``` The new default exception controller will also change the error response content according to https://tools.ietf.org/html/rfc7807 for `json`, `xml`, `atom` and `txt` formats: Before (HTTP status code `200`): ```json { "error": { "code": 404, "message": "Sorry, the page you are looking for could not be found" } } ``` After (HTTP status code `404`): ```json { "title": "Not Found", "status": 404, "detail": "Sorry, the page you are looking for could not be found" } ``` * Deprecated the `ExceptionController` and `PreviewErrorController` controllers, use `ErrorController` from the HttpKernel component instead * Deprecated all built-in error templates, use the error renderer mechanism of the `ErrorHandler` component * Deprecated loading custom error templates in non-html formats.

Pass it as the first argument instead. * The `Length` constraint expects the `allowEmptyString` option to be defined when the `min` option is used. Set it to `true` to keep the current behavior and `false` to reject empty strings. In 5.0, it'll become optional and will default to `false`. * Overriding the methods `ConstraintValidatorTestCase::setUp()` and `ConstraintValidatorTestCase::tearDown()` without the `void` return-type is deprecated. * deprecated `Symfony\Component\Validator\Mapping\Cache\CacheInterface` and all implementations in favor of PSR-6. * deprecated `ValidatorBuilder::setMetadataCache`, use `ValidatorBuilder::setMappingCache` instead. * The `Range` constraint has a new message option `notInRangeMessage` that is used when both `min` and `max` values are set.
