Jan 1, 2026

January 2026: Delivered a BPMN Editor Work Item Definitions (WIDs) loading feature and strengthened test infrastructure across the kie-tools, kie-drools, kie-kogito-runtimes, and kie-kogito-examples repositories. Key feature delivered: BPMN Editor loads WIDs from a global directory or the BPMN file location, enabling WID reuse and richer BPMN modeling. Major upgrades: Testcontainers upgraded to 2.0.3 across all four repos to improve test reliability and CI stability, addressing environment-related flakiness. Cross-repo consistency and collaboration were demonstrated through coordinated dependency upgrades and a co-authored WID feature commit. Overall impact: improved modeling capabilities for customers, faster feedback through more stable tests, and a more predictable CI/CD pipeline. Technologies/skills demonstrated: Java, Maven, dependency management, Testcontainers, BPMN tooling, cross-repo collaboration, and co-authored development work.

March 2025 performance highlights focused on delivering DMN evaluation UX improvements and clarifying documentation across repos. In apache/incubator-kie-tools, the DMN Runner now integrates evaluation data with KIE Sandbox, backed by new state properties and methods to manage/display evaluation results. Evaluation statuses and data structures were refactored to align with the DMN editor, and terminology was standardized by renaming 'Execution' to 'Evaluation' across the runner and related UI for a unified user experience. In IBM/bamoe-docs, the Evaluation Highlights documentation was published, explaining how to enable/disable the feature, the meaning of evaluation badges for decision nodes, and the expression hit count for Decision Tables and Conditional Expressions in both form and table modes.
