Spring for Apache Kafka version 3.3.3 is compatible with Kafka Client 3.9.0, though the framework's compile-time dependency uses Kafka Client 3.8.1. To use Kafka Client 3.9.0 or later with version 3.3.3, applications must manually upgrade their Kafka Client version.

We are excited to announce the release of Spring AI 1.0.0 Milestone 6. To celebrate this release, we have created a special AI-generated music playlist to enhance your blog reading and coding experiences!

As usual, this release includes several new features and bug fixes. We have continued to focus on reviewing the codebase from a design perspective. While we have tried to make this transition smooth by deprecating methods and classes for one release cycle, there are some breaking changes we know about and potentially some that we don't, so please bear with us.

On behalf of the team and everyone who has contributed, I’m delighted to announce the first milestone of the 2025.0.0 release train. If you are confused how on earth a milestone of 2025.0.0 can ship after an earlier 2025.1.0 milestone, rest assured, we are too, at times. Calver versioning is based off the actual release date. 2025.0 will go GA in May while 2025.1 is planned for November. Since we started working on the major release 2025.1 last year already, we were able to ship a first milestone in January. Hopefully, this explanation helps to clear up any confusion.
