DeepSeek Harness 0.1.2-alpha.1 adds plugin-controlled provider sign-in, letting agents and callers select provider, model, and reasoning effort for subagents with authorization checks. Question history now displays as readable Q&A cards showing cancelled and interrupted states. Images render immediately while uploading in the background and appear from users, assistants, and tool results in Trajectory. Full ACP support covers session controls, model settings, MCP, permissions, and cancellation. Applications launch via dsh Profiles in Python SDK and ACP modes, and public WebFetch is enabled by default with SSRF protection.
