@ -151,6 +151,7 @@ Moreover, the following APIs have been removed/updated without deprecation:
* The default constructor in `org.springframework.batch.core.configuration.annotation.DefaultBatchConfigurer` has been removed. Use the constructor that accepts a `DataSource` instead, see https://github.com/spring-projects/spring-batch/wiki/Spring-Batch-5.0-Migration-Guide#job-repositoryexplorer-configuration-updates.
* The method `org.springframework.batch.core.step.builder.SimpleStepBuilder#processor(Function)` has been removed to allow lambdas to be passed as item processors. See https://github.com/spring-projects/spring-batch/issues/4061 for more details about the rationale behind this removal. If you use an actual `Function` as argument for `SimpleStepBuilder::processor`, then you can change that to `.processor(function::apply)` to migrate to v5.
* `org.springframework.batch.item.file.builder.FlatFileItemWriterBuilder#resource`, `org.springframework.batch.item.file.ResourceAwareItemWriterItemStream#setResource`, `org.springframework.batch.item.json.builder.JsonFileItemWriterBuilder#resource`, `org.springframework.batch.item.json.JsonFileItemWriter#JsonFileItemWriter`, `org.springframework.batch.item.support.AbstractFileItemWriter#setResource`, `org.springframework.batch.item.xml.builder.StaxEventItemWriterBuilder#resource` and `org.springframework.batch.item.xml.StaxEventItemWriter#setResource` have been updated to accept a `org.springframework.core.io.WritableResource` instead of a `org.springframework.core.io.Resource`. For more details about this change, please check https://github.com/spring-projects/spring-batch/issues/756
* The static type `org.springframework.batch.item.data.builder.RepositoryItemReaderBuilder.RepositoryMethodReference` along with the method `org.springframework.batch.item.data.builder.RepositoryItemReaderBuilder#repository(RepositoryMethodReference<?>)` have been removed.
