July 2025 — cqframework/clinical-reasoning: Delivered two major features focusing on measure evaluation throughput and release readiness. Implemented activation-frame-based state management and config-driven deferral of validation to streamline evaluation workflow. Completed codebase housekeeping to resolve rename conflicts and updated version to enable release readiness, setting the stage for a clean release pipeline. These changes improve processing efficiency, stability, and maintainability, and reduce time-to-release for downstream clients.
