Spring Batch 4.0.0.M1 is now available

We are pleased to announce that Spring Batch 4.0.0.M1 is now available via Github and the Pivotal download repository. This release represents the first milestone for the Spring Batch 4.0 release. Many thanks to all of those who contributed to this release.

What’s new?

We have taken this opportunity to look at Spring Batch from a new light in a few areas. Specifically:
* Java baseline
* Dependency baseline
* Java configuration

Java Baseline

Spring Batch has historically followed the baseline of Spring Framework with the intent of providing the best interoperability between Spring Batch and Spring Framework versions as possible. Spring Batch 4.0 is taking this opportunity to upgrade to Spring Framework 5 as the minimum required version. With this, Java 8 will be required for Spring Batch 4. If you’ve been using Spring Batch with Java 8 already, this should be a pretty transparent as Spring Batch has had a solid Java 8 story for years now. Doing things like the following has been supported as long as Java 8 has been around:

Introducing Kotlin support in Spring Framework 5.0

Update: see also Spring Framework 5 Kotlin support reference documentation.

Following the Kotlin support on start.spring.io we introduced a few months ago, we have continued to work to ensure that Spring and Kotlin play well together. One of the key strengths of Kotlin is that it provides a very good interoperability with libraries written in Java. But there are ways to go even further and allow writing fully idiomatic Kotlin code when developing your next Spring application. In addition to Spring Framework support for Java 8 that Kotlin applications can leverage like functional web or bean registration APIs, there are additional Kotlin dedicated features that should allow you to reach a new level of productivity.
