In May 2025, Sergey Murashov refactored the Universal Message components within the diadoc/diadocsdk-csharp repository, focusing on improving code organization and maintainability. He moved the УС classes into a dedicated Diadoc.Api.DataXml.UniversalMessage namespace, ensuring that existing XML serialization behavior and the external API surface remained unchanged. This targeted update, implemented in a single commit, reduced future maintenance risk and aligned the codebase with architectural standards. Sergey utilized his expertise in C#, code refactoring, and namespace management to deliver a solution that enables easier future enhancements in the Universal Message area without introducing functional regressions or breaking compatibility.
