## [未发布]

本节累积面向 **2.1.0** 里程碑（[里程碑 2](https://github.com/bytedance/deer-flow/milestone/2)）的工作。

### ⚠ 不兼容变更（Breaking Changes）

- **技能：** 沙箱现在将 `/mnt/skills` 保留给“仅启用项”的托管投影视图。
  `DEER_FLOW_HOST_SKILLS_PATH` 与 `SKILLS_HOST_PATH` 不再使用；Docker/AIO 和
  hostPath 部署会从 `DEER_FLOW_HOST_BASE_DIR` 推导投影路径。指向 `/mnt/skills`
  或其子路径的 E2B operator 挂载会被跳过并告警，避免遮蔽托管投影；请将额外内容
  挂载到其他容器路径。用户投影会从磁盘重读全局启用状态，使切换在下一次获取沙箱时
  跨 Gateway worker 生效。既有 E2B 沙箱在重建前仍保留创建时快照；PVC 模式暂不提供
  已禁用技能的文件系统隔离。([#4178])
- **沙箱：** E2B 现在将 `sandbox.replicas` 作为进程级容量上限来强制执行。默认的
  `wait` 策略会等待 `acquire_timeout`，随后令当前智能体回合失败。DeerFlow 不会自
  动重试该回合。可使用 `burst` 配合 `burst_limit` 允许有限地超出额度多开 VM。`reject`
  策略可在返回容量错误前先回收一个预热 VM。([#4391])
- **技能：** 包含 `SKILL.md` 的目录现在是一个运行时包边界。该包内嵌套的 `SKILL.md`
  文件被视为支撑数据，不再注册为独立技能；若自定义目录结构较为特殊，需将可独立加
  载的技能移到不带自身 `SKILL.md` 的命名空间目录下。([#4098])
- **记忆：** 记忆系统现已可插拔（`memory.manager_class` 选择后端；默认 `deermem`
  自包含）。DeerMem 私有配置从 `memory:` 顶层移入 `memory.backend_config`，`/memory/config`
  响应（以及 `client.get_memory_config()`）的结构也发生了变化。([#4122])
- **记忆：** `/memory/config` 与 `client.get_memory_config()` 不再返回扁平的 DeerMem
  字段（`storage_path`、`max_facts`、`debounce_seconds`、`token_counting`、`guaranteed_*`
  、`staleness_*` 等）。改为返回 `{enabled, mode, injection_enabled, manager_class,
  backend_config}`，其中 `backend_config` 是一个由当前后端自行解释的不透明 dict
  。记忆*数据*响应（`/memory`、`/memory/status` 的 data）未变。读取旧扁平字段的
  外部 API / SDK 客户端需改为读取 `backend_config`。([#4122])
- **记忆：** 自定义 `memory.storage_class` 发生迁移：旧的默认路径 `deerflow.agents.memory.storage.FileMemoryStorage`
  已不存在（现为 `deerflow.agents.memory.backends.deermem.deermem.core.storage.FileMemoryStorage`
  ）。自定义 `MemoryStorage` 子类的 `__init__` 必须接受 `config`（此前为无参）。
  损坏或过期的 `storage_class` 会记录错误并回退到 `FileMemoryStorage`（不会崩溃
  ）——请更新路径与签名以恢复使用。([#4122])
- **记忆：** `storage_path` 的语义由“文件路径”改为“根目录”。抽象化之前，绝对 `storage_path`
  是共享的记忆文件（不按用户隔离），相对值则是 data base_dir 下的全局文件。现在
  `storage_path`（无论绝对或相对）都是根目录；按用户的记忆存放在 `{storage_path}/users/{uid}/memory.json`
  。若升级后仍保留旧的默认 `storage_path: memory.json`（一个相对文件名），会导致
  按用户的记忆孤立，或在保存时触发 `NotADirectoryError`。因此旧版迁移会**带告警
  丢弃以 `.json` 结尾的文件式 `storage_path` 值**，且当 `storage_path` 解析到一
  个已存在的文件时工厂会**抛出异常**。如需自定义根目录，请将 `memory.backend_config.storage_path`
  设置为一个目录。([#4122])
- **记忆：** 当 `memory.mode: tool` 搭配一个未实现 `search()` 的后端时，现在会在
  Gateway 启动时由 `MemoryManager` 的不变量校验快速失败并抛出 `ValueError`，而不
  是启动成功后在每次 `memory_search` 调用时静默返回空结果。两个内置后端都实现了
  `search()`（DeerMem 会检索，`noop` 返回 `[]`），因此仅影响未覆盖 `search()` 就
  接入的自定义后端。这是有意为之——静默返回空比启动期报错更糟。修复方式：切换到 `mode:
  middleware`，或覆盖 `search()`（并设置 `supports_search=True`）。([#4324])

- **配置：** `database.checkpoint_delta_snapshot_frequency` 已迁移为
  `database.checkpoint_delta.snapshot_frequency`，默认值从 `1000` 改为 `10`。
  旧顶层字段仍会在告警后映射到新字段，显式的新字段优先。依赖旧默认值的 delta
  模式部署现在会将快照频率提高 100 倍；如需保留原节奏，请显式设置为 `1000`。([#4516])
- **Docker：** 两份 compose 文件发布的入口端口现在默认只绑定回环地址
  (`127.0.0.1`)。依赖旧 `0.0.0.0` 绑定的部署必须设置 `BIND_HOST` 才能向其他网卡
  暴露服务。([#4618])

### 新增

#### 智能体与运行时

  能体与子智能体之间累加共享。([#3412])
- **中间件：** 结构化的工具结果元数据与工具进度状态机，让运行时对多步工具流拥有
  一等可见性。([#3601])

  消息、记忆与工具状态），以结构化运行时元数据的形式发出，压缩（compaction）不再
  丢失这些信息。([#3556]、[#3887]、[#3906])
- **运行时：** 目标延续（goal continuation）允许 run 跨多个智能体回合朝目标继续
  执行，并跟踪、限制 `continuation_count`。([#3858])

- **运行时：** Delta 模式 checkpoint 历史缓存（内存/Redis）支持 O(1) 增量合成，
  通过 `database.checkpoint_cache` 配置。([#4638])
- **调度器：** `scheduler.recursion_limit` 可设置定时运行的 LangGraph super-step
  上限（默认 1000，与 Web UI 一致，并受 `max_recursion_limit` 限制）。([#4848])
- **运行时：** 每次工具调用都会携带由运行时签发且可防篡改的工具回执；有界回执账本
  会注入模型上下文，使智能体能在报告中引用执行证据。默认通过新的 `verification`
  配置节启用。([#4659])
- **澄清：** 人工输入卡片支持结构化表单字段，智能体可精确请求所需信息。([#4406])
- **子智能体：** 内置子智能体会接收当前日期上下文锚点，使相对日期任务与主智能体
  直接处理时表现一致。([#4797])
- **子智能体：** 设置页新增部署级子智能体目录；自定义智能体可配置显式 worker
  allowlist，并在 prompt 与执行阶段同时强制执行。([#4887])
- **子智能体：** 并发由统一的进程级容量控制器管理；可选 `batch_task` 工具可把大量
  独立项目作为基于 SQL 的持久、可恢复批次执行，支持租约、有限重试、暂停、恢复与
  取消，并在聊天中展示进度。([#4998])

#### 记忆
- **记忆：** 记忆合并（consolidation）合成碎片化的事实，并通过 LLM 为每条事实分
  配的 `expected_valid_days` / `staleFactsToExtend` 进行过期审查，剪除静默过期的
  事实。([#3996]、[#3860]、[#4143])
- **记忆：** 保证注入纠正事实（并优雅降级），使用户的纠正始终能触达模型。([#3592])
- **记忆：** 精简可插拔的 `MemoryManager` 接口以方便后端接入——新后端不再需要实现
  未被调用的抽象方法，DeerMem 专有的 hook 注入也移出共享工厂。([#4326])

  记忆 provider 的 Honcho。([#4509]、[#4528]、[#4730])
- **记忆：** 混合事实淘汰策略综合多种信号，决定容量满时应丢弃哪些事实。([#4789])

#### 技能
- **技能：** 原生 SkillScan（阶段一）在加载时静态分析技能包；`describe_skill` 支
  持延迟发现，模型按需获取技能 schema，而非一开始就加载全部技能。([#3033]、[#3775])
- **技能：** 按用户的自定义技能隔离，并配合沙箱挂载。([#3889])

- **技能：** 选中一个技能后技能列表会重新打开，便于连续附加多个技能。([#4639])

  fastCRW provider——并新增 Browserless `web_capture` 截图工具和 Brave `image_search`
  。([#3675]、[#3821]、[#3585]、[#3881]、[#3866])
- **MCP：** MCP 工具调用支持按 server 的 `tool_call_timeout`，并提供路由提示引导
  模型选用正确的 server。([#3843]、[#4004])
- **MCP：** 新增官方 OpenViking `/mcp` 示例，通过 DeerFlow 通用 MCP 客户端暴露其
  原生工具集。([#4745])
- **社区工具：** 将“智能体化浏览器控制”作为会话的一等能力——基于 Playwright 的浏
  览器会话由智能体操作，用户可在工作区中观察或接管。([#4187])
- **社区工具：** Lark / 飞书 CLI 集成打包了运行时安装、官方 `lark-*` 技能包与交
  互式授权流程，使该集成不再依赖手动环境配置。([#3971])

- **集成：** 可在“设置 > 集成”中按用户切换 Lark/飞书应用凭据；新 App ID/Secret

- **ACP：** 支持 MiniMax Code (`mcode acp`) 作为原生外部编码智能体；ACP thought
  chunk 不再拼接进工具结果。([#4846])

#### MCP
- **MCP：** 新增持久任务运行时：长时工具任务通过持久 driver 跨 Gateway 重启继续，
  进度与完成通知显示在聊天 UI 中。([#4665]、[#4690]、[#4833])
- **MCP：** 共享 MCP server 可注入按用户区分的凭据；未映射用户默认拒绝，存储的
  凭据在 Gateway API 响应中脱敏。([#4868])
- **MCP：** 新增按 server 的 `tool_name_prefix`，让已自行命名空间化工具的 server
  保留原始工具名；默认行为不变。([#4624])

#### 渠道
- **渠道：** 把 IM 的 `channel_user_id` 以 `DEERFLOW_CHANNEL_USER_ID` 暴露给沙箱
  命令。([#3926])
- **渠道：** 对同一会话的密集消息进行排队，并在批次间保留话题卡片预览。([#3988])

#### 认证与防护
- **认证：** 通用 OIDC / SSO 认证，并支持 Keycloak。([#3506])
- **护栏：** 已认证的运行时上下文在 `GuardrailRequest` 中暴露，安全干预以 run 事
  件的形式持久化。([#3665]、[#3837])
- **认证：** “保持登录”选项，配合统一的会话 cookie 策略（HTTPS 下使用持久化 `Secure`
  cookie，公网 HTTP 下使用会话 cookie）。([#4255])
- **认证：** 部署方可关闭本地自注册，将新账号限制为仅通过 SSO / OIDC 开通。([#4311])
- **鉴权：** 内置 RBAC 鉴权 provider 与统一工厂，并在装配期（模型可见前移除工具
  ）与运行期（拒绝被禁用的调用）双重强制执行工具鉴权。([#4260]、[#4370])

- **鉴权：** Gateway 路由权限改由已配置的 `AuthorizationProvider` 推导，不再使用
  固定表。([#4439])
- **鉴权：** 模型权限会在 Gateway 路由和智能体运行时双重执行，获取沙箱时还会校验
  `sandbox:execute`。([#4540]、[#4911])

#### 沙箱与 provisioner

  容器端口。([#4016]、[#3928])

- **沙箱：** 新增云沙箱 provider：Tenki 与 OpenSandbox。([#4382]、[#4877])
- **沙箱：** K8s provisioner 模式新增可选的 lark-cli 凭据 broker sidecar，将 Lark
  应用密钥与 OAuth token 移出沙箱文件系统；沙箱只看到转发命令的 shim。默认关闭。
  ([#4501])

#### 扩展与插件
- **扩展：** 新增 out-of-tree Python 扩展系统，可贡献中间件、任务生命周期与系统模型
  observer、Gateway 服务和 HTTP 路由，并用 `deerflow extensions` 管理。([#4636]、
  [#4684]、[#4780])
- **扩展：** 扩展可观察消息来源、中间件策略、智能体装配指纹、上下文压缩、护栏决策
  和工具的 MCP 来源。`deerflow-extension-api` 升至 0.2.0，0.1 扩展会在启动时被拒绝。
  ([#4863])

#### 持久化

- **前端：** 自定义智能体聊天支持 Browser Live。([#4719])
- **会话：** 分支会话自动使用 `Title (2)`、`Title (3)` 等编号区分标题，最近会话
  列表以树形连接线展示父子关系。([#4983])

#### 可观测性与工具
- **可观测性：** trace-id 关联与增强日志，以及通过 Monocle 实现的智能体可观测性
  。([#3902]、[#4024])
- **工具：** 类 Hermes 的终端工作台（`deerflow` CLI，基于 `DeerFlowClient`），以
  及脱敏的社区支持包（support-bundle）生成器。([#3760]、[#3886])
- **安装向导：** 安装向导现在会询问 OpenAI 兼容的 gateway 模型是否支持 thinking
  ，并新增火山引擎 Coding Plan 快速安装路径。([#3428]、[#4141])
- **TUI：** `clear` 命令。([#4306])

- **TUI：** 支持透明终端背景。([#4631])

### 变更

- **前端性能：** 保持公共根页面和本地化文档静态化；懒加载关闭的工作区面板及编辑器/
  高亮依赖；增量推导流式消息状态；限制流式 Markdown 工作量；虚拟化超长消息与聊天
  列表；暂停屏幕外装饰效果，并对代表性路由设置 JS/CSS 预算。
- **浏览器：** 协商二进制 Browser Live JPEG 帧，兼容旧 JSON/base64 协议；每次刷新
  只呈现最新帧，并撤销已替换的 object URL。
- **Artifact：** 普通文本 artifact 支持 HTTP byte-range 流式读取；Web UI 初始预览
  限制为 1 MiB，用户显式请求后才加载完整文件。
- **沙箱：** Helm chart 现在默认将每个沙箱的 Service 设为 `ClusterIP` 而非 `NodePort`
  ，因此代码执行沙箱只能通过集群内 Service DNS（`http://sandbox-<id>-svc.<ns>.svc.cluster.local`
  ）访问，不再绑定到每个节点（包括 GKE / EKS / AKS 上外部可达的）网卡。升级时现
  有 chart 安装会从 NodePort 切到 ClusterIP。如需保留原有可达性（外部探测命中 30xxx
  端口，或 gateway 不在 K8s 的 Docker-Compose / 混合部署路径），请设置 `provisioner.sandboxServiceType:
  NodePort`（必要时配合 `provisioner.nodeHost`）。provisioner 本身不变（自 #4016
  起已按模式感知）。([#4190])
- **技能：** 处于激活态的限制型技能若要委派给子智能体，必须在 `allowed-tools` 中
  显式声明 `task`。只读发现基础设施（`tool_search` 与 `describe_skill`）仍可用，
  但无法为被禁用的业务工具授予 schema 可见性或执行权限。([#4098])
- **记忆：** 抽象化之前位于顶层的 `memory.*` DeerMem 字段（`storage_path`、`max_facts`
  、`debounce_seconds`、`model_name`、`token_counting`、`staleness_*`、`consolidation_*`
  等）在加载时会**带告警自动迁移到 `backend_config`**，因此升级不会静默地把自定
  义配置回退为默认值（`model_name` -> `backend_config.model.model`）。将它们移到
  `config.yaml` 的 `memory.backend_config` 下即可消除告警。([#4122])
- **记忆：** 新增 `memory.mode`（`middleware` | `tool`）；`tool` 模式会注册供模
  型直接调用的记忆工具（`memory_search`/`add`/`update`/`delete`），取代被动的逐
  回合摘要。`manager_class` 解析改为快速失败（未知后端时抛出 `ValueError`，而非
  静默回退）。([#4023])
- **中间件：** 声明式分层中间件构建器；`ThreadData` 现在先于 `Uploads` 运行。([#3809])
- **沙箱：** 宿主机到虚拟机的输出脱敏正则现在统一归属，消除重复的模式编译。([#4108])
- **文档：** `AGENTS.md` 成为智能体指引的权威来源，`CLAUDE.md` 通过 `@AGENTS.md`
  导入；模块指南同步刷新。([#3770])

- **记忆：** OpenViking 后端改用官方适配器；旧 trusted-mode 的 `auth_mode`/`account`
  字段会被拒绝，改用绑定凭据的 USER API key。([#4707])
- **网关：** 在 run-event journal 出现之前创建的会话，会在首次新 run 前把 checkpoint
  历史回填为 seed event，使旧会话升级后仍可见且顺序正确。([#4590])
- **智能体：** 子智能体委派改按净收益路由；除非并行延迟、专长能力或上下文隔离明确
  有益，否则主智能体默认直接执行。([#4384])

### 修复

- **运行时：** 会话元数据现在仅在 run 通过启动屏障后才切换为 `running`，待取消的
  run 不再短暂呈现 `running` 状态；worker 启动期间客户端可能观察到先前的会话状态
  。([#4450])
- **运行时：** 通过原子化、感知租约的接管（takeover）claim 重新检查孤儿候选 run
  ，使扫描后的成功心跳仍保持 run 活跃，且仅有一个 reconciler 上报恢复。([#4424]
  、[#4434])
- **技能：** `allowed-tools` 只作用于斜杠激活或实际加载的主智能体技能，避免被动
  启用的技能与评测 fixture 从每个 run 中移除 MCP、网络、文件与委派工具。([#4095]
  、[#4098]、[#4192])
- **模型：** 在所有 `BaseChatOpenAI` 子类（`VllmChatModel`、`MindIEChatModel`、`PatchedChatMiMo`
  、`PatchedChatStepFun`、`PatchedChatMiniMax`）上生效 `api_base`，而不只是 `ChatOpenAI`
  / `PatchedChatOpenAI`。此前这五个子类会静默丢弃配置的 endpoint，随后以一个含义
  不明的 `unexpected keyword argument 'api_base'` 让每次请求都失败；它们也未被纳
  入未知配置 key 的告警。两者现在都基于 `issubclass(BaseChatOpenAI)` 判断。([#4146])
- **智能体：** 在 LLM 请求前合并 `SystemMessage`；保证工具运行后仍有可见响应；避
  免在流结束前发起默认的 LLM 标题调用；为省略号预留空间以使本地标题遵守 `max_chars`
  ；并将工具输出尾部前移，使回退截断遵守 `max_chars`。([#3711]、[#4033]、[#3885]
  、[#4052]、[#4017])
- **智能体：** 动态上下文的日期扫描跳过无日期的提醒；从不含 `config.yaml` 的智能
  体目录加载 `SOUL.md`；`update_agent` 的旧版智能体守卫要求存在 `config.yaml`；
  并拒绝空的 `SOUL.md` 更新。([#3685]、[#4136]、[#4166]、[#4219])
- **中间件：** 为循环检测的工具频次计数器加窗口，避免长 run 误触；阻止标题中间件
  流式输出 token；修复“同内容列表耗尽时位置回退误取无关 todo”的问题；在 `_apply`
  、`before_agent`、`_clear_run_state` 与 `_drain_pending_warnings` 之间持有 token
  预算锁；丢弃孤立的 `ToolMessage` 以免严格型 provider 返回 400；净化非法 tool-call
  参数；并在 dangling 修复中从空的 tool-call 名称与畸形 tool-call id 恢复。([#4072]
  、[#3566]、[#3709]、[#3714]、[#4080]、[#4193]、[#4008]、[#4246])
- **子智能体：** 继承 `LoopDetectionMiddleware` 与摘要中间件，使工具循环能被打断
  、步骤能被捕获；将回合预算上限以 `MAX_TURNS_REACHED` 暴露并附带部分结果；在累
  加式 `stop_reason` + `token_budget` 上统一护栏上限；压缩前注入持久上下文；保留
  父 checkpoint 命名空间；在 general-purpose 系统 prompt 中禁用 `task` 工具；flush
  失败时重新缓冲子智能体事件以避免丢失步骤；并修复子智能体 `run_id` 为 `None` 时
  丢失 `loop_capped` 停止原因的问题。([#3931]、[#4009]、[#3949]、[#3980]、[#4040]
  、[#4215]、[#4161]、[#4082]、[#4059])
- **记忆：** 加固对 null / 空值边界情况的处理——跳过仅含空白的事实；在更新、检索
  与剩余三处原始读取中规整 null 的 `confidence` / `source.confidence`；将显式 `null`
  的 `backend_config` 值视为缺省；修复事实无 id 或事实列表为空时的 `KeyError` /
  `UnboundLocalError`；停止防抖更新队列的忙等（busy-spin）；并在优雅关闭时刷写记
  忆队列以防丢失。([#3719]、[#4074]、[#4076]、[#4034]、[#4217]、[#3993]、[#3992]
  、[#4073]、[#4181])
- **运行：** 关闭 run 原子性中的多 worker 归属缺口；在租约续期于截止期前无法确认
  时令本地执行快速失败，并在 peer 接管后对迟到的完成写入加围栏；多 worker 下将 cancel
  降级为租约接管；让 `create_thread` 在插入竞态时仍幂等；从运行时上下文读取 `stop_reason`
  ；并将 run 时长持久化到 checkpoint 以供历史读取。([#4003]、[#4064]、[#4414]、[#3800]
  、[#4188]、[#4118]、[#4431])
- **运行时：** 序列化 SQLite event-store 写入，避免按会话的序列号冲突；在 journal
  中跳过隐藏的人类消息；并去掉 `_merge_stream_text` 中静默丢弃 delta 的行为。([#4077]
  、[#3698]、[#4085])
- **网关：** 按真实 `event_type` 关联会话消息反馈；把 artifact 服务、gateway 上
  传与 Discord 渠道中的阻塞文件 IO 移出事件循环；限制上传文件的上下文清单；并实
  时追踪畸形的 Redis 重连 id。([#3651]、[#3551]、[#3935]、[#3927]、[#3917]、[#4012])

## [2.0.0] — 2026-06-15

DeerFlow 2.0 是围绕"超级智能体"框架的彻底重写，核心包含子智能体、持久化记忆、
沙箱执行以及可扩展的技能（Skill）/工具系统。本版本与 1.x 系列**没有共享代码**，
原有的 Deep Research 框架仍在
[`main-1.x` 分支](https://github.com/bytedance/deer-flow/tree/main-1.x)上维护。
