January 2026: SAP/jenkins-library delivered Artifact Versioning Improvements by adding an exclusion flag to artifactPrepareVersion and simplifying the API surface. These changes enable excluding specific files from version commits, improve reproducibility, and reduce usage friction. Implemented via two commits: 344c44cca0f126087817c42a51326653e1d809a2 (feat: Artifact prepare version exclusion flag) and ff07bd1c46541ae0041514886fc6fd164b805eee (fix: reduce parameter scope). Impact: more reliable artifact/versioning workflows, easier contributor onboarding, and improved maintainability. Technologies/skills demonstrated: Java-based Jenkins Library, API design/refactoring, versioning logic, and collaborative development (Co-authored-by phgermanov).
