DeepSeek Harness Code 0.1.0-BETA3

DeepSeek Harness Code is a community distribution, not an official DeepSeek product.

Published as GitHub Latest on 2026-08-22: release · native package Run 32550253496 · source 9762f8efe1e761ff6b175b209972103bff88e091.

What changed

• Upgrades the packaged and first-launch Harness runtime from @deepseek-ai/dsh@0.1.0-rc.8 to the official 0.1.1-rc.2 release (tag commit b150a551b8d465e31e418e1b2eaf5e79bbb7d28e).
• Adds upstream support for prioritizing the DeepSeek Files API for image uploads and reusing already uploaded files.
• Adds upstream model-aware image preprocessing, including automatic resizing and format conversion.
• Keeps the BETA2-2 installer, lifecycle, system-Node guidance, loopback security and native no-Node gates.
• Rebases the product-owned preset localization, macOS sidebar safe-area, persistent Bash prompt and Windows plugin-path quoting patches onto the exact 0.1.1-rc.2 packages.

Official upstream notes: DeepSeek Harness v0.1.1-rc.2.

Update from an earlier DHSC release

Open Settings → General → Check for updates in an earlier DeepSeek Harness Code build. The app reads the GitHub Latest update-manifest.json, offers 0.1.0-BETA3 when it is newer, asks before replacing the app, and verifies the selected asset's byte size and SHA-256 first.

The release publishes Universal macOS DMG/ZIP, Windows x64/arm64 NSIS, Linux x64/arm64 AppImage/deb, and update-manifest.json. All six native runners completed install/runtime/no-Node validation before GitHub created the Release. The manifest's five automatic-update targets exactly match the published assets' byte sizes and SHA-256 digests.

Requirements and known limit

• Official system Node.js >=22.13 is required; the app detects common official installation locations but does not silently install Node.
• macOS remains ad-hoc signed and not Apple-notarized. Use the app-scoped unsigned installation instructions; do not disable Gatekeeper globally.
