May 2025 monthly summary focused on CI/CD performance upgrades through large runner migrations across 26 SonarSource public repositories. Implemented standardized upgrades to ubuntu-latest-large (and ubuntu-24.04-large where applicable), delivering faster builds, more reliable tests, and better resource utilization. No user-facing bugs fixed this month; primary emphasis on performance, scalability, and maintainability of CI pipelines. This work reduced queue times and improved feedback cycles for PR validation, releases, and quality checks, aligning with broader goals of faster delivery and higher developer productivity.

In February 2025, SonarSource/orchestrator delivered a formal vulnerability disclosure policy by adding a SECURITY.md file. This documentation captures the process for reporting security vulnerabilities, provides direct contact information for Sonar's security team, and references responsible disclosure guidelines. The work enhances security governance, improves readiness for external researchers, and supports compliance and audits across the orchestrator repository. No major bug fixes were reported in this period for this repo, while the security policy artifact positions the team for faster triage and remediation in future cycles.
