Jan 1, 20252025-01 monthly summary: Implemented cross-client Windows file clipboard clearing in the shared rustdesk/hbb_common repository by adding a new CliprdrTryEmpty protobuf message. This enables a clear clipboard state across Windows clients when a copy occurs in one client should clear in another, improving multi-client workflow reliability and user experience. The change was delivered via commit e646eb9f4de014894280b81699cc94c76e11a164 and aligns with existing clipboard infrastructure, preserving backward compatibility. Overall impact is stronger cross-client consistency, reduced user confusion, and a solid foundation for further clipboard-related interoperability. Technologies demonstrated include protobuf schema evolution, Windows interop, and disciplined, traceable feature delivery in a shared core library.
