DeepSeek Harness has launched the v0.2.2-alpha.3 pre-release, bringing expanded capabilities across code review, automated task management, SDKs, and the plugin ecosystem. Key updates include an experimental unified entry point for change requests and worktrees, which supports browsing local code and PR diffs, handing specified code snippets and comments over to the Agent for processing, and introduces a new multi-file modification tool called apply_patch. Automated tasks have been upgraded to host-level unified management, now supporting manual creation, direct editing, and execution across both new and old sessions. In addition, Python and TypeScript SDK capabilities have been improved, plugin functionality expanded, the narrow-screen experience on mobile optimized, multiple known issues fixed, and the file modification security policy adjusted. As a pre-release, this version does not yet offer a desktop installation package.
