Laying Groundwork for the Future​

Following the foundational work in 10.0.0, this release introduces key upgrades and deprecations, improves compatibility, and continues efforts to simplify the developer and authoring experience. While not as sweeping as the prior release, 10.1.0 brings meaningful enhancements across the stack.

Platform Upgrades​

• Quarkus upgraded to version 3.15.3.1 (from 3.8.4)
• Spring Boot upgraded to version 3.4.3 (from 3.2.6)

These updates align with our goal of keeping KIE technologies up-to-date with modern Java ecosystems.

Drools​

Advancing Rule Units​

Rule Units remain targeted at greenfield projects and continue to evolve. These projects are better positioned to work around current limitations.

While RuleUnits provide a strong foundation, there are critical gaps that must be addressed before they can be considered a complete replacement for classic DRL. Examples include ambiguity in OOPath syntax, limited support for Decision Tables, and a lack of comprehensive test coverage.

Improvements are being investigated to simplify the use of OOPath in combination with accumulate and to improve the overall authoring experience.

Rule Orchestration / startProcess​

The startProcess() API has been deprecated since version 8.x and should not be called from client code, as doing so will result in a RuntimeException. Although the method still exists due to internal dependencies and because it is part of a shared interface with jBPM, it is no longer functional and is expected to be removed in a future version. The recommended approach is to use the new code-generation-based process.

DMN 1.5 Support​

Both the editor and engine now support the latest DMN 1.5 specification.

jBPM and Kogito​

• Introduction of a new user task subsystem
• Support for transactions in compact architecture
• Infinispan usage is now deprecated and will be removed in the next version

SonataFlow Operator Enhancements​

• Incorporates the ability to configure the SonataFlow workflows and supporting services databases using the SonataFlowPlatform.
• Incorporates the ability to initialize the supporting services databases using a dedicated Job, via configuration in the SonataFlowPlatForm.
• Incorporates the ability to produce all the events communications using the Knative Eventing System, via configuration in the SonataFlowPlatform.

Tooling Updates​

• A new Test Scenario Editor with full DMN 1.5 support is now available
• Classic DMN Editor and native binaries for Extended Services are both deprecated and will be removed in the next release

Known Limitations​

• JIT runners are not working on Windows and macOS

A "Journey of Transformation"​

Transitioning to the Apache Foundation was a monumental step for the KIE community, and the path to this release has been transformative. While the prolonged gap between releases posed challenges, it allowed us to focus on critical adjustments and improvements, paving the way for a stronger foundation. Here's an overview of the significant efforts that made this release possible:

• Comprehensive CI system overhaul to align with Apache standards.
• Code adjustments for Apache policy compliance, including license reviews.
• Fully reproducible builds for all .jar artifacts.
• Remove cyclical dependencies and other technical debt.
• Automate critical release processes to streamline future releases.
• Java 17, Jakarta 10, Quarkus, and SpringBoot upgrades
• And many more...
