June 2026 monthly summary for konflux-ci/mobster focusing on business value, reliability, and maintainability. Key features delivered include restoring backward compatibility for the deprecated dockerfile-json workflow in the mobster CLI by implementing a runtime fallback to the new buildprobe metadata path when available, and gracefully using the legacy dockerfile-json path otherwise. This dual-path support reduces migration risk for users and preserves existing CI workflows while enabling modernization. Also completed a targeted code quality cleanup to unblock refactors during the transition.
