DeepTutor v1.6.2 Release Notes

Release Date: 2026.08.31

v1.6.2 adds immersive YouTube learning and a plugin-driven visualizer catalog, then sharpens Reading, Knowledge, Partners, updates, and My Agents. The retired Playground API and Gemini CLI connection are the only compatibility changes.

What's New

Learn beside a synchronized video

Paste a YouTube URL to open privacy-enhanced playback beside the tutor, keep transcript evidence bound to timestamps, explain the current cue, and resume progress later. Administrators can select a self-hosted Invidious origin without rebuilding materials; native playback works without the optional public-caption adapter.

Visualize and consult through extensible catalogs

Visualize now uses the shared agent loop and an installed visualizer catalog for SVG, Mermaid, Chart.js, interactive HTML, Manim, and optional GeoGebra. Declarative browser-only visualizer ZIPs run in sandboxed iframes. My Agents adds Hermes Agent, OpenClaw, and DeepSeek Harness alongside six existing local harnesses.

A tighter Home, Reading, and update path

Home unifies chat behavior across ordinary, reading, mastery, and watching workspaces. Web sources become safe versioned snapshots, reading citations link only when verified against the turn's material, LaTeX selections stay grounded, and Settings → About can check, classify, and safely apply eligible PyPI updates.

Clearer Knowledge and Partner operations

MinerU now accepts common raster images plus DOCX, PPTX, and XLSX in addition to PDF. Knowledge Center separates libraries from Local, Server, Cloud, and External engines with readiness preflight. Partner channel cards report live connection/setup state, including browser QR onboarding, instead of sending routine diagnosis to logs.

Upgrade Notes

Run pip install -U deeptutor; Docker users pull ghcr.io/hkuds/deeptutor:latest. Existing data, knowledge indexes, video progress, and reading snapshots need no migration.

• Public-caption tutoring is optional. Install pip install -U 'deeptutor[video-learning]' to enable transcript-grounded video explanations. YouTube/Invidious playback still works without it.
• Gemini CLI is retired as a My Agents harness. Existing gemini settings are left untouched but are no longer registered; the old settings route redirects to Antigravity. Connect Antigravity, Hermes Agent, OpenClaw, or DeepSeek Harness instead.
• The Web Playground and /api/v1/plugins/* tester API are removed. deeptutor plugin list/info still inspects runtime tools and capabilities. Browser visualizers now use /api/v1/visualizers and declarative visualizer packages.
• The English and Chinese guides have been updated together at deeptutor.info.
