March 2025 monthly summary for wolfi-dev/advisories focusing on risk-managed upgrades and upstream collaboration. No new feature deliveries were completed this month due to a Kubernetes upgrade blocker tied to missing feature flags. The team prioritized security posture and project stability by documenting the blocker, mapping dependencies, and preparing for an upstream remediation once feature flags are available. This approach preserves system reliability while ensuring readiness for a future upgrade once upstream changes land.
