We are excited to announce the release of Apache KIE (Incubating) 10.2.0, marking another significant milestone in the project's evolution under the Apache Software Foundation. This release represents a major step forward in modernization and Apache compliance, with substantial improvements to tooling and platform dependencies.

A Major Leap in Modernization​

The 10.2.0 release focuses on critical infrastructure improvements and a transformative update to our editing capabilities. This release removes legacy dependencies and introduces modern tooling that aligns with Apache guidelines and contemporary development practices.

Important Tooling Changes​

New BPMN Editor​

The most significant change in this release is the introduction of the new BPMN Editor. This modern editor replaces the legacy GWT-based tooling and represents a fundamental shift in our approach to process modeling.

Key benefits of the new BPMN Editor:

• Modern, responsive user interface
• Improved performance and user experience
• Better integration with contemporary web technologies
• Enhanced maintainability and extensibility

Removal of Classic Editors​

As part of our commitment to modernization and Apache compliance, we have removed the classic BPMN and DMN editors. These GWT-based editors have been deprecated in previous releases, and their removal in 10.2.0 brings us one step closer to graduating.

Platform Upgrades​

• Quarkus upgraded to version 3.27.2 (from 3.15.3.1)
• Spring Boot upgraded to version 3.5.10 (from 3.4.3)
• Java 21 support

These updates ensure KIE technologies remain current with the latest Java ecosystem advancements, providing improved performance, security, and feature sets.

• Management Console read-only mode support, improved OpenTelemetry integration, and enhanced user experience
• Build Tools Gradle plugin improvements, enhanced Maven plugin, and better build discovery
• Various bug fixes and UX improvements across all tooling components

OptaPlanner​

• Removed experimental optaplanner-operator to streamline the codebase
• Documentation migrated to unified kie-docs repository

Acknowledgments​

We would like to extend a special thank you to Alex Procelli for his exceptional work in helping to deliver this release. His dedication and effort were instrumental in bringing 10.2.0 to completion in an accelerated timeframe.

We also want to recognize Tiago Bento for his contribution of the new and improved BPMN Editor. This work represents a major advancement in our tooling capabilities and will benefit the entire Apache KIE community for years to come.

We are pleased to announce the release of Apache KIE (Incubating) 10.1.0, the first follow-up milestone since the project's rebirth under the Apache Software Foundation. This release reflects the project's continued momentum and commitment to modernization, usability, and stability across the KIE components: Drools, jBPM, OptaPlanner, Kogito, SonataFlow and Tools.

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
