Sep 1, 2025September 2025 — NREL/EnergyPlus. Delivered a new API overload for ScanPlantLoopsForNodeNum removing the ObjexxFCL dependency and added an optional error-reporting parameter, enhancing flexibility and testability. Performed comprehensive code-quality improvements with clang-format across OutputReportPredefined.hh, OutputReportTabular.cc, and PlantUtilities.cc (no functional changes). Fixed UI reliability by correcting frame ordering in the utility tab and updating the binary version. Completed EP-Launch configuration and utility-management cleanup by adjusting AppGPostProcess and temporarily commenting out EP-Compare, streamlining utility program management. These efforts improve testability, reduce coupling, boost UI stability, and simplify release readiness and maintenance.
