# Changelog

All notable changes to DeerFlow are documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/)
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [2.0.0] — 2026-06-15

DeerFlow 2.0 is a ground-up rewrite around a "super agent" harness with
sub-agents, persistent memory, sandbox execution, and an extensible
skills/tools system. It shares no code with the 1.x line, which now lives on
the [`main-1.x` branch](https://github.com/bytedance/deer-flow/tree/main-1.x).

This release closes [milestone 2.0.0](https://github.com/bytedance/deer-flow/milestone/1)
with **180 merged pull requests** since the first 2.0 milestone tag.

### ⚠ Breaking changes

- **harness:** Hydrate runs from `RunStore` and persist interrupted status. Run
  cancellation/multitask semantics now require a working RunStore on the
  worker that owns the run; cross-worker cancels return 409 instead of
  silently appearing successful. ([#2932])

### Added

#### Agents & runtime
- **agent:** Custom-agent self-updates with user isolation — agents can persist
  edits to their own `SOUL.md` / `config.yaml` from inside a normal chat.
  ([#2713])
- **loop-detection:** Make loop detection configurable with per-tool frequency
  overrides; keep configurable on/off switch. ([#2586], [#2711])
- **loop-detection:** Defer warning injection so detector pairs cleanly with
  tool-call lifecycle. ([#2752])
- **run:** Propagate `model_name` from the gateway request through the runtime
  and persistence stack into the SQLite-backed store. ([#2775])
- **subagents:** Stream subagent token usage to the header via terminal task
  events. ([#2882])
- **memory:** Add `memory.token_counting` config to opt out of tiktoken for
  network-restricted deployments. ([#3465])
- **suggest:** Make AI follow-up question suggestions optional. ([#3591])

#### Models & integrations
- **models:** Add StepFun reasoning model adapter. ([#3461])
- **community:** Add Brave Search web search tool. ([#3528])
- **channels:** Enhance Discord with mention-only mode, thread routing, and
  typing indicators. ([#2842])
- **im:** Add user-owned IM channel connections — users can bind their own
  Slack/Telegram/Discord/Feishu/DingTalk/WeChat/WeCom accounts on top of the
  operator-configured bots. ([#3487])
- **models:** Add patched MiMo reasoning content support. ([#3298])
- **models:** Add MiniMax provider for image/video/podcast skills plus a new
  music-generation skill. ([#3437])
- **community:** Add SearXNG and Browserless web search/fetch tools. ([#3451])
- **community:** Add Serper Google Images provider for `image_search`. ([#3575])
- **channels:** Stream Telegram agent replies by editing the placeholder
  message in place. ([#3534])

#### Observability
- **trace:** Set the LangGraph trace name to `lead_agent` (or the custom
  agent's `agent_name`) for cleaner Langfuse/LangSmith traces. ([#3101])
- **frontend:** Refine token usage display modes. ([#2329])
- **defaults:** Enable token usage tracking by default. ([#2841])
- **defaults:** Raise default summarization trigger threshold. ([#3174])
- **trace:** Attribute subagent spans to the parent thread's Langfuse trace.
  ([#3611])

#### Skills
- **skill:** Add `blocking-io-guard` skill for blocking-IO triage and runtime
  anchors. ([#3503])
- **skill:** Add maintainer issue and PR workflow skill. ([#3554])
- **skill:** Strengthen the maintainer orchestrator review workflow. ([#3606])

### Performance

- **harness:** Push thread metadata filters into SQL instead of post-filtering
  in Python. ([#2865])
- **runtime:** Index runs by `thread_id` to avoid O(n) scans in `RunManager`.
  ([#3499])
- **runtime:** Index messages in `MemoryRunEventStore` to avoid O(n) scans.
  ([#3531])
- **persistence:** Cache `Base.to_dict` column reflection per class. ([#3654])
- **sandbox:** Speed up `should_ignore_name` in glob/grep walks. ([#3657])

### Security

- **upload:** Reject symlinked upload destinations. ([#2623])
- **uploads:** Add Windows support for safe symlink-protected uploads.
  ([#2794])
- **mcp:** Mask sensitive values in MCP config API responses. ([#2667])
- **mcp:** Harden the MCP config endpoint against malformed input. ([#3425])
