April 2026 monthly summary for vespa-engine/system-test focusing on packaging and dependency management improvements that enhance build reproducibility, security, and onboarding. The team delivered modernization of dependency management through pyproject.toml, removing legacy requirements.txt, and enforcing Python 3.10+ across the dataprep module for consistent builds and compatibility with modern tooling. A key security effort addressed vulnerability scans by updating minimum Python version and dependencies to mitigations around pillow and orjson, aligning with Mend findings.

March 2026 focused on security workflow simplification and vulnerability remediation across vespa-engine repositories. The month delivered leaner CI/CD pipelines, reduced tooling debt, and improved security posture through targeted dependency hardening and standardization of security practices across multiple repos.

February 2026: Applied a critical security patch in dependency management by upgrading h11 to 0.16.0 in vespa-engine/sample-apps. The fix was implemented via a targeted single-commit change (0426404e64bd261c7762c7e8bb2e5f8140db43f2) and validated through CI, reducing security risk and preserving compatibility for downstream apps.
