September 2026

30 releases: 0.7.12 → 0.7.21

September brought major expansions to Deep Agents' capabilities, with significant additions to conversation management, model support, and reliability improvements across all components.

Action needed
  • Subagent mode renamed from handoff to isolated.
  • Task tool calls now reject unknown argument keys instead of silently dropping unexpected input.
  • FileInfo.size now correctly represents file size in bytes across backends.

Highlights

  • Added Discord channel support with improved gateway failure reporting and new chat-scoped conversation history with configurable storage.
  • Introduced subagent conversation forking and flexible subagent execution modes, including background expendable subagents and per-task tool selection.
  • Added GPT-6 Astra support and pricing for Fireworks GLM-5.3 models, plus new MCP configuration tools and hot reload support.
  • Expanded tool capabilities with native streaming PTC tool calls, improved file handling with better truncation explanations, and new /help and /btw commands.
  • Improved workspace isolation, conversation reliability, and MCP safety with better OAuth credential handling and bounded resource operations.

New

  • Subagent conversation forking in the SDK and renaming subagent mode from handoff to isolated.
  • Discord channel support including gateway failure reporting and chat-scoped conversation history with hybrid search.
  • MCP configuration tools, channel-based server authorization, hot reload for MCP configuration, and OAuth/device authentication for Slack and GitHub.
  • Background expendable subagents, fresh subagents, per-task tool selection, and on-demand subagent execution.
  • A /help command, /btw command for isolated side questions, and currenttime tool with timezone-aware wall-clock cron schedules.
  • Inline thread mentions and picker via @@ syntax and targeted conversation deletion support.
  • Cache bust timer in the footer and durable Debug Console cost breakdown with token and cost refresh while viewing.
  • Support for managing tool approvals through tools.json and persistent LangGraph checkpoints.

Improved

  • Renamed subagent mode from handoff to isolated for clarity.
  • General-purpose subagents now default to fork mode and Auto classifier defaults by provider.
  • Improved workspace isolation by resolving project policy per workspace, scoping project dotenv to workspaces, and isolating LangSmith auth.
  • Better workspace configuration with bound conversation support, effective approval mode tracing, and request-time working directory binding.
  • Enhanced MCP reliability with hardened OAuth device-flow, credential handling, and bounded configuration updates.
  • Improved cost-warning behavior by showing session warnings in a modal and suppressing historical warnings when resuming.
  • Made thread browsing and resume flows more resilient with recoverable failures and clearer message count headers.
  • Better large tool result previews that clearly explain clipping or truncation, including byte-cap losses and per-line clipping.

Fixed

  • Fixed glob sorting to tolerate missing modifiedat values and character counting in ls and glob output.
  • Fixed request-time working directory binding and marketplace plugin installs to accept bare relative source paths.
  • Fixed invalid partial tool-call patching and updated imputed ToolMessage content in PatchToolCallsMiddleware.
  • Fixed local voice transcription and embedding retries, and ensured local model downloads persist.
  • Fixed binary content in StateBackend.uploadfiles being tagged as base64.
  • Fixed prompt clipboard word deletion behavior and local MCP cache warming to not block the event loop.
