During January 2026, Andrey Tretjakov focused on simplifying the API surface in the diadoc/diadocsdk-csharp and diadoc/diadocsdk-java repositories by removing the AutoSignReceipts feature. He deleted related methods, data structures, and protobuf definitions, using C#, Java, and Protocol Buffers to ensure consistency across both SDKs. This work responded directly to user feedback, aligning product functionality with evolving requirements while reducing maintenance overhead. By achieving cross-language feature parity, Andrey improved onboarding and support processes. The depth of the changes demonstrates a thoughtful approach to API design, prioritizing clarity and maintainability without introducing new bugs or regressions during the update.
