DeepTutor v1.4.3 Release Notes

Release Date: 2026.06.12

The biggest release since v1.4.0. TutorBot grows up into
Partners, Chat collapses into a single agent loop, multi-user gets real
per-user isolation, and Visualize, Co-writer, the file viewer, document
parsing, and the CLI all level up. The docs at
deeptutor.info have been rebuilt alongside —
every Partner channel now has its own setup guide, in English and Chinese.

Upgrading from TutorBot? Migration is automatic and non-destructive:
on first start your bots become Partners — channel configs (secrets
included), model selection, and the soul library carry over, and each
bot's persona becomes its SOUL.md. The old data/tutorbot/ tree is
left untouched, so rolling back stays safe. One breaking change: the
HTTP API moved from /api/v1/tutorbot/... to /api/v1/partners/... —
update any scripts that call it. The [tutorbot] pip extra keeps
working as an alias for [partners].

What's New

TutorBot → Partners

Your bots are now Partners — same idea, much stronger execution:

• Partners run on the same agent loop as product Chat (the separate
  nanobot engine is gone), so every Chat improvement reaches your IM bots
  automatically.
• Production-grade message pipeline: send retries, dedup, coalescing, and
  a per-channel delivery matrix.
• Live streaming replies on Telegram, Discord, and Feishu — answers
  render as they are generated.
• New WeCom AI Bot channel; 15 channel connectors total, from Slack
  and Discord to DingTalk, QQ, and WhatsApp.
• Web chat now takes attachments — drop images or files straight into
  a Partner conversation.
• A rewritten soul template library with an in-app editor.

One Loop for Chat

The two-phase targeting/respond pipeline is gone. Chat now runs a single
exploring agent loop with native tool calling end to end — fewer moving
parts, smarter tool use, no more mis-routed turns. A new Activity
header keeps the status line pinned on top and folds the thinking/tool
trace away once the answer lands.

Real Multi-User Isolation

• Per-user grants v2: tools, MCP servers, and exec access are controlled
  per user from the admin UI.
• Workspace layout moves to data/users/<uid> + data/system; existing
  deployments migrate automatically.
• The exec runner mounts only the calling user's workspace subtree (new
  Dockerfile.runner), so sandboxed code never sees another user's files.

Visualize, Rebuilt

Inline, theme-aware SVG rendering; structured prompts; and a local
validate + repair pass replacing the old full-round LLM review — faster,
cheaper, and far fewer broken diagrams. Fullscreen now works for every
visual type.

Sharper Everyday Tools

• Co-writer renders flowcharts and sequence diagrams via Mermaid, and
  selection-scoped questions can pull from your knowledge base and the web.
• File viewer: true in-browser docx/xlsx previews, drag-to-resize, and
  the Activity panel now lives alongside your open files.
• MinerU cloud parsing as an alternative to the local backend
  (/settings/mineru), and question extraction now captures question
  type, difficulty, and answers.
• Office skills work out of the box — docx/pdf/pptx/xlsx generation no
  longer requires flipping a sandbox switch.
• CLI chat, rewritten: aligned with the new loop protocol, interactive
  ask_user prompts in the terminal, Ctrl-C cancellation, and collapsible
  thinking output.

Fixes That Matter

Qwen models no longer leak JSON wrappers into answers, Windows installs
get UTF-8 right, Zulip bots catch mentions reliably, and a
file-descriptor exhaustion bug plus false-positive health checks are gone.

Docs, Synced

deeptutor.info was rebuilt with this release:
a dedicated setup guide for every Partner channel (English + 中文),
refreshed screenshots throughout, and updated CLI and server API
references.

Upgrade Notes

• pip install -U deeptutor — the migrations run automatically on first
  start, and all of them are idempotent.
• Legacy multi-user/ trees move to data/users/ in place; TutorBot
  bots become Partners (see the note at the top).
• Exec-based skills now allow subprocesses by default. To restore the old
  behavior, set sandbox_allow_subprocess to false in system settings.
