As a long-time required topic and the high interest that we observed in the GitHub tracking issue, we look forward to your feedback after you adopt Spring Boot 3 with this alpha version. As a reminder, the Camunda Platform 7.20.0 minor release is scheduled for 10th of October 2023.

Quarkus 3

We have updated our Quarkus Extension to the latest Quarkus 3 version. This version brings many new features and changes. For a complete list, see the Quarkus 3 major release blog post.

From the extension’s perspective, the most important changes are the deprecation of Java 11 and the switch to Jakarta EE 10.

Quarkus has a very comprehensive guide for updating and also offers an update tool.

You can find more details about the extension on our dedicated Quarkus Integration page.

New JUnit 5 extension for DMN

Back in 2021, we introduced a community extension allowing you to test the Camunda engine with JUnit 5. If you’re not familiar with it yet, have a look at Ingo’s blog post about it. With Camunda 7.17, this extension moved into the product stack and is part of our regular releases.

With this latest alpha release, we additionally add a JUnit 5 extension specifically for DMN. This allows you to inject a configurable DMN engine into your JUnit 5 test code like you would inject the process engine. You can use it in combination with the initial JUnit 5 extension for the process engine as well as standalone for DMN only.

Big shout out to our community member Dejan Ćebetarević for not only bringing this topic up but also contributing the code for it!
