I am pleased to announce that the first milestone of Spring Shell 4.0 is now available on Maven Central!

What's new?

This milestone release is the first step toward a modern version of Spring Shell, aligned with the rest of the Spring portfolio.

The main focus of this first milestone is alignment with Spring Framework 7 and Spring Boot 4.

Spring Shell 4.0.0-M1 is now based on Spring Framework 7.0.0-RC2 and Spring Boot 4.0.0-RC1.

For the complete list of changes, please check the release notes.

What's next?

We plan to release Spring Shell 4.0 GA in November, after the Spring Boot 4.0 GA release.

In the meantime, we will ship a few milestones and release candidates with the following changes:

• Migrate nullability annotations and checks to jSpecify
• Improve project modularity to streamline dependencies
• Test infrastructure updates to JUnit 6
• Build and release infrastructure improvements
• Documentation improvements

Thanks to all contributors who helped make this release possible! As we continue our work on Spring Shell 4.0, we look forward to your feedback on GitHub Issues and GitHub Discussions.
