Jul 1, 2025July 2025 monthly summary for dynawo/dynawo: Delivered Dynawo v1.7.0 with a new JSON export mode for constraints and timeline data, refined constraint filtering with DISABLED option, and updated error dictionary; release notes/docs updated to reflect v1.7.0 with download URLs and libraries. Addressed a constraint deletion order bug and performed addConstraint refactor to only instantiate a Constraint when a new constraint is added; ensured the toRemove list is sorted before reverse iteration to guarantee correct deletion order. These changes improve data interoperability, reliability, and maintainability, accelerating customer deployments and reducing risk in constraint workflows. Notable commits include 1113f884e855c6653c1155849429441026592a74, 651ba209c5296828abcfd54bdcc44caded31b34b, and 14877a02d1d7dd1bc0a55bbde88e8f9fec9c7920.

Mar 1, 2025March 2025 achievements focused on delivering reliable simulation capabilities, expanding data interoperability, and strengthening CI/CD robustness for dynawo/dynawo. Key feature delivery includes adding support for Final State Values (FSV) in CSV format to the diff tool, enabling CSV-based comparison alongside existing XML support, and optimizing transformer model simulation parameters for improved stability and accuracy. Major bug fixes addressed initialization correctness in Modelica, improved reliability of complex variable initialization parsing in ReaderOMC, and enhanced CI/build resilience (NRT workflows and Fedora build warnings). These changes collectively reduce risk in production simulations, improve test reliability, and enable easier cross-format data analysis. The work demonstrates capabilities in Modelica modeling, regex-based parsing, unit testing, and CI/CD automation, delivering clear business value through more reliable simulations and maintainable tooling.
