 - **gateway:** Cache-aware cost accounting attributes token costs to cached vs.
  uncached paths; a Redis stream bridge enables distributed event streaming; and
  manual context compaction is exposed to the user. ([#3920], [#3191], [#3969])
+- **runtime:** Dual-mode checkpoint storage with LangGraph `DeltaChannel` cuts
+  thread storage from O(N²) to near-linear for long research/coding runs.
+  ([#4292])
+- **agent:** Config-declared lead-agent middlewares let deployments add custom
+  `AgentMiddleware` classes without patching the runtime chain. ([#3964])
+- **agents:** Per-agent model and generation settings (`temperature`,
+  `max_tokens`, `thinking_enabled`, `reasoning_effort`) override the shared

 [English](./CHANGELOG.md) | 中文

+## [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）
+
+- **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])
+
+### 新增
+
+#### 智能体与运行时
+- **中间件：** 新增 `TokenBudgetMiddleware`，强制单个 run 的 token 预算，在主智
+  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])
+- **上下文：** 每个 run 记录生效的记忆身份，并在摘要过程中持久化持久上下文（系统
+  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])
+- **子智能体：** 系统维护的委派账本（delegation ledger）防止对在途任务重复委派，
+  并设总委派上限以约束单个 run 的扇出。([#3877]、[#4115])
+- **子智能体：** 在会话中持久化并展示子智能体的步骤历史。([#3845])
+- **工具：** 结构化摘要取代预览中原始的超大工具输出。([#3377])
+- **文件：** 文件工具引入确定性的“写前读”版本门控，避免覆盖并发编辑。([#3912])
+- **网关：** 感知缓存的成本核算将 token 成本归因到缓存 / 未缓存路径；Redis stream
+  桥接启用分布式事件流；并向用户暴露手动上下文压缩。([#3920]、[#3191]、[#3969])
+- **运行时：** 双模式 checkpoint 存储（基于 LangGraph `DeltaChannel`）将长调研 /
+  编码 run 的会话存储从 O(N²) 降至近线性。([#4292])
+- **智能体：** 配置声明的主智能体中间件，让部署方无需修改运行时链即可加入自定义
+  `AgentMiddleware` 类。([#3964])
+- **智能体：** 按智能体的模型与生成设置（`temperature`、`max_tokens`、`thinking_enabled`
+  、`reasoning_effort`）可覆盖共享的模型 profile。([#4347])
+- **运行时：** 记录终态的 artifact 投递回执，使预期要 `present_files` 的 run 在
+  投递失败时不再误报成功。([#4365])
+- **上传：** 通过 `list_uploaded_files` 工具懒加载历史文件，而非注入完整清单。([#4174])
+
+#### 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：** 增量式按智能体作用域的 Markdown 事实存储，按智能体隔离事实，且更新
+  单条事实时无需重写或重建整个集合的索引。([#4279])
+- **记忆：** 记忆消息处理新增会话水位（watermark）、无意义回合过滤与持久化队列，
+  使抽取不再每回合都重新喂入完整会话。([#4447])
+
+#### 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])
+
+#### 模型与集成
+- **社区工具：** 新增网络检索 / 抓取引擎——GroundRoute、Crawl4AI（`web_fetch`）与
+  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])
+- **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])
+
+#### 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])
+
+#### 沙箱与 provisioner
+- **沙箱：** 新增 E2B 与 BoxLite（micro-VM）沙箱 provider；BoxLite 自带预热池。([#3883]
+  、[#3940]、[#3951])
+- **provisioner：** ClusterIP Service 与按技能作用域的 PVC 挂载，并支持配置沙箱
+  容器端口。([#4016]、[#3928])
+
+#### 前端
+- **前端：** 支持对助手回合进行分支，以及针对引用追问的侧边对话。([#3950]、[#3934])
+- **前端：** 支持重新生成最新回答。([#3637])
+- **前端：** 引用来源证据面板、智能体 run 的工作区变更评审，以及可视化的 `ask_clarification`
+  卡片。([#3907]、[#3945]、[#3956])
+- **前端：** 语音输入、方向键回溯 prompt 历史、输入框内容润色，以及“（思考了 N
+  秒）”思考时长标签。([#4036]、[#3718]、[#3986]、[#3627])
+- **前端：** 用 `agents_api` 特性开关控制智能体 UI 的可见性，并在后端与 UI 中持
+  久化 AI 回合时长。([#3769]、[#3663])
+- **前端：** 将斜杠技能（slash-skill）激活渲染为内联标签（chip）。([#3981])
+- **前端：** 本地化的 AI 辅助声明。([#4374])
+- **前端：** 支持置顶最近会话。([#4442])
+- **前端：** 在输入框中校验 `/goal` 目标长度。([#4337])
+
+#### 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])
+
+### 变更
+
+- **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])
+
+### 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])
+- **上传：** 在写入前先占位转换后的 Markdown 配套文件名，使同词干（stem）的两个
+  可转换上传（或一个可转换上传加一个同词干 `.md` 上传）不再在同一请求内静默互相
+  覆盖。`uploads.auto_convert_documents` 开启时，配套 `.md` 会得到唯一名称（如 `a_1.md`
+  ）；`POST /threads/{id}/uploads` 与 `DeerFlowClient.upload_files` 都会在 `markdown_file`
+  中返回实际文件名。([#4288])
+- **配置：** 将为 null 的对象型配置节规整为默认值；在 store 与 sync checkpointer
+  中遵循统一数据库配置；并让旧版 DB 回填在已存在的表上补建缺失的 `Index` 对象。([#3573]
+  、[#3904]、[#3994]、[#4090])
+- **模型：** 将 `stream_chunk_timeout` 默认值应用到所有 `BaseChatOpenAI` 子类；
+  并为 `ChatOpenAI` 把 `api_base` 规范化为 `base_url`，遇到未知配置 key 时给出告
+  警。([#4102]、[#3790])
+- **MCP：** 按 server 隔离工具发现失败；同步 session-pool 单例的生命周期；按配置
+  内容 + 路径（而非仅更新的 mtime）失效工具缓存；在加载时校验 MCP 工具名，使延迟
+  prompt 保持惰性；并按来源 server 路由工具，而非按名称前缀。([#3772]、[#3797]、
+  [#4124]、[#4154]、[#3812])
+- **技能：** 斜杠技能每个 run 仅激活一次，而非每次模型调用都激活；补齐技能安装安
+  全扫描的覆盖缺口；在评审 CI 中识别被完全删除的技能包，并在 SkillScan 中把剩余
+  的 `requests` / `httpx` 方法识别为网络出口；在无参 skills prompt 段落复用已解
+  析的 app 配置；并支持不重启 Gateway 即可重新加载已挂载技能。([#4103]、[#3924]
+  、[#4169]、[#4130]、[#4160]、[#4264])
+- **沙箱：** 为反向路径翻译与输出脱敏正则加上段边界；在 `read_file` / `str_replace`
+  中处理单边行范围与空文件；对齐 AIO bash 工作目录；在 Windows 的反向 resolve 包
+  含性检查中使用 `os.sep`；在 bash 命令中规范化 Windows 反斜杠路径；阻止 `glob`
+  / `grep` / `ls` 暴露被禁用技能的文件；并在沙箱审计中允许合法的 heredoc 命令。([#4035]
+  、[#4053]、[#4078]、[#4079]、[#4051]、[#4058]、[#3869]、[#4096]、[#3786])
+- **沙箱：** 同步沙箱 provider 单例的生命周期（含并发回归测试），并让 provisioner
+  中的 k8s 调用不阻塞事件循环。([#3730]、[#3941])
+- **沙箱：** 将沙箱 artifact 挂载与渠道用户对齐；修复非 root / NFS 主机上的本地
+  开发（`make dev`）；停止时回收 macOS 上的 nginx 进程；并修复 Docker 中生产环境
+  Postgres 的 UV-extras 检测。([#3729]、[#3590]、[#3828]、[#3897])
+- **渠道：** 在解析渠道 provider 配置前先校验 provider；对 GitHub webhook 重投递
+  去重，并丢弃冗余的 GitHub review-comment webhook 扇出；把斜杠技能白名单检查限
+  定在 run 的 owner 作用域；将飞书文件消息批量到一个会话，并以 bot @mention 前缀
+  分发飞书群命令；在 `/connect` 绑定码前接受前导 @mention，且不把裸 `connect` 当
+  作绑定命令；阻止飞书创建会话话题并限流卡片更新；让 UI 运行时渠道配置优先于 `config.yaml`
