I am pleased to announce that Spring Batch 4.3.0-RC1 is now available from our milestone repository.

What’s New?

This release comes with a number of new features that you can find in the release notes, but here are the major highlights:

1. GraalVM Support

A lot of work has already been done in Spring Framework to support running some types of Spring applications on GraalVM. In this release, we made changes in Spring Batch to correctly run Batch applications on GraalVM as well.

Spring Batch 4.3.0-M2 is out!

On behalf of the Spring Batch team, I am pleased to announce that Spring Batch 4.3.0-M2 is now available from our milestone repository.

What’s new?

This release comes with a number of new features and enhancements that you can find in the release notes, but here are the major highlights:

1. Kafka support enhancements

By default, the KafkaItemReader reads a topic from the beginning. When we initially introduced this reader in v4.2, it was not possible to configure it to read records from a custom offset. In this release, we added this feature. As a result of this addition, it is now possible to configure the reader to start from the offset stored in Kafka.
