June 2026 focused on feature-flag driven delivery, validation, and reliability across the MeasureAuthoringTool suite. Delivered: 1) Feature-flag driven Create Library and Draft Dialogs with validation. 2) US Quality Core feature flag support in the CQL library service. 3) Library version management enhancement to retain multiple versions in the included library map. Also drove quality through test suite cleanup and cross-repo fixes: removed obsolete tests for library dialogs; improved CQL coverage accuracy by skipping empty annotations; and VSAC-compatible validation parameter handling for null code systems. Overall impact: faster, safer feature rollouts; improved data integrity and compatibility; and maintainable code with clearer versioning and tests.

May 2026 monthly summary: Delivered core feature improvements and reliability gains across the QDM translation and FHIR service stacks, upgraded core dependencies, and drove maintainability. Key outcomes include upgraded CQFramework, enhanced CQL translation to ELM with expanded testing, TranslatorVersionController refinements, and UI/template improvements for endpoint metadata. These efforts reduce risk, improve deployment confidence, and accelerate downstream feature delivery for measure authoring workflows.
