This release introduces a new feature that lets you monitor your batch jobs by using Micrometer. By default, Spring Batch collects metrics (such as job duration, step duration, item read and write throughput, and others) and registers them in Micrometer’s global metrics registry under the spring.batch prefix. These metrics can be sent to any monitoring system supported by Micrometer.

For more details about this feature, please refer to the Monitoring and metrics chapter.

This release adds a new KafkaItemReader and KafkaItemWriter to read data from and write it to Kafka topics. For more details about these new components, please refer to the Javadoc.

This release adds a new AvroItemReader and AvroItemWriter to read data from and write it to Avro resources. For more details about these new components, please refer to the Javadoc.

The reference documentation has been updated to match the same style as other Spring projects.
