## [Unreleased]

This section accumulates work toward the **2.1.0** milestone
([milestone 2](https://github.com/bytedance/deer-flow/milestone/2)).

### ⚠ Breaking changes

- **skills:** A directory containing `SKILL.md` is now a runtime package
  boundary. Nested `SKILL.md` files inside that package are supporting data and
  are no longer registered as independent skills; unusual custom layouts must
  move independently loadable skills under a namespace directory without its
  own `SKILL.md`. ([#4098])
- **memory:** The memory system is now pluggable (`memory.manager_class` selects
  a backend; default `deermem` is self-contained). DeerMem-private settings moved
  from the top level of `memory:` into `memory.backend_config`, and the
  `/memory/config` response (and `client.get_memory_config()`) changed shape.
  ([#4122])
- **memory:** `/memory/config` and `client.get_memory_config()` no longer return
  flat DeerMem fields (`storage_path`, `max_facts`, `debounce_seconds`,
  `token_counting`, `guaranteed_*`, `staleness_*`, ...). They return
  `{enabled, mode, injection_enabled, manager_class, backend_config}` where
  `backend_config` is an opaque dict the active backend self-interprets. Memory
  *data* responses (`/memory`, `/memory/status` data) are unchanged. External
  API/SDK clients reading the old flat fields must read `backend_config` instead.
  ([#4122])
- **memory:** Custom `memory.storage_class` moved: the old default path
  `deerflow.agents.memory.storage.FileMemoryStorage` no longer exists (now
  `deerflow.agents.memory.backends.deermem.deermem.core.storage.FileMemoryStorage`).
  Custom `MemoryStorage` subclasses must accept `config` in `__init__` (was
  no-arg). A broken/old `storage_class` logs an error and falls back to
  `FileMemoryStorage` (won't crash) -- update the path + signature to restore it.
  ([#4122])
- **memory:** `storage_path` semantics changed from a FILE path to a root
  DIRECTORY. Pre-abstraction, an absolute `storage_path` was the shared memory
  file (opting out of per-user isolation) and a relative value was the global
  file under the data base_dir. Now `storage_path` (absolute or relative) is the
  root directory; per-user memory lives at `{storage_path}/users/{uid}/memory.json`.
  An upgrade keeping the old default `storage_path: memory.json` (a relative file
  name) would orphan per-user memory or hit `NotADirectoryError` on save, so the
  legacy migration **drops file-style `storage_path` values (ending in `.json`)
  with a warning** and the factory **raises** if `storage_path` resolves to an
  existing file. Set `memory.backend_config.storage_path` to a directory for a
  custom root. ([#4122])

### Added

#### Agents & runtime

- **middleware:** New `TokenBudgetMiddleware` enforces a per-run token budget,
  shared additively across the lead agent and subagents. ([#3412])
- **middleware:** Structured tool-result metadata and a tool-progress state
  machine give the runtime first-class visibility into multi-step tool flows.
  ([#3601])
- **context:** Record the effective memory identity per run and persist durable
  context (system messages, memory, and tool state) across summarization,
  emitting it as structured runtime metadata so compaction no longer drops it.
  ([#3556], [#3887], [#3906])
- **runtime:** Goal continuations let a run resume toward a goal across multiple
  agent turns, with `continuation_count` tracked and capped. ([#3858])
- **subagents:** A system-maintained delegation ledger prevents redundant
  re-delegation of an in-flight task, and a total delegation cap bounds fan-out
  per run. ([#3877], [#4115])
- **subagents:** Persist and display subagent step history in the thread.
  ([#3845])
- **tools:** Structured synopses replace raw oversized tool output in previews.
  ([#3377])
- **files:** Deterministic read-before-write version gate for file tools
  prevents clobbering concurrent edits. ([#3912])
- **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])

#### Memory

- **memory:** Memory consolidation synthesizes fragmented facts, and a staleness
  review prunes silently-outdated facts using LLM-assigned per-fact
  `expected_valid_days` / `staleFactsToExtend`. ([#3996], [#3860], [#4143])
- **memory:** Guaranteed injection of correction facts (with graceful fallback)
  so user corrections always reach the model. ([#3592])

#### Skills

- **skills:** Native SkillScan (phase 1) statically analyzes skill packages at
  load, and `describe_skill` enables deferred discovery so the model fetches a
  skill's schema on demand instead of loading all skills up front. ([#3033],
  [#3775])
- **skills:** Per-user custom skill isolation with sandbox mounting. ([#3889])

#### Models & integrations

- **community:** New web search/fetch engines - GroundRoute, Crawl4AI
  (`web_fetch`), and a fastCRW provider - plus a Browserless `web_capture`
  screenshot tool and Brave `image_search`. ([#3675], [#3821], [#3585], [#3881],
  [#3866])
- **mcp:** Per-server `tool_call_timeout` for MCP tool calls, and routing hints
  that guide the model to the right server. ([#3843], [#4004])

#### Channels

- **channels:** Expose the IM `channel_user_id` to sandbox commands as
  `DEERFLOW_CHANNEL_USER_ID`. ([#3926])
- **channels:** Queue rapid same-thread messages and preserve topic-card
  previews across batches. ([#3988])

#### Auth & guardrails

- **auth:** Generic OIDC/SSO authentication with Keycloak support. ([#3506])
- **guardrails:** Authenticated runtime context is exposed in `GuardrailRequest`,
  and security interventions are persisted as run events. ([#3665], [#3837])

#### Sandbox & provisioner

- **sandbox:** New E2B and BoxLite (micro-VM) sandbox providers; BoxLite ships
  with a warm pool. ([#3883], [#3940], [#3951])
- **provisioner:** ClusterIP Services and scoped per-skill PVC mounts, plus a
  configurable sandbox container port. ([#4016], [#3928])

#### Frontend

- **frontend:** Branching support for assistant turns and side conversations for
  quoted follow-ups. ([#3950], [#3934])
- **frontend:** Regenerate the latest answer. ([#3637])
- **frontend:** Citation-sources evidence panel, workspace change review for
  agent runs, and a visualized `ask_clarification` card. ([#3907], [#3945],
  [#3956])
- **frontend:** Voice dictation, prompt-history recall with arrow keys, composer
  input polishing, and a "(thought for N seconds)" thinking-duration chip.
  ([#4036], [#3718], [#3986], [#3627])
- **frontend:** Feature-gate the agents UI behind the `agents_api` flag, and
  persist AI turn duration in backend and UI. ([#3769], [#3663])

#### Observability & tooling

- **observability:** Trace-id correlation with enhanced logging and agent
  observability via Monocle. ([#3902], [#4024])
- **tooling:** A Hermes-like terminal workbench (`deerflow` CLI) backed by
  `DeerFlowClient`, plus a redacted community support-bundle generator. ([#3760],
  [#3886])
- **setup:** The setup wizard now asks whether OpenAI-compatible gateway models
  support thinking, and a Volcengine Coding Plan quick-setup path was added.
  ([#3428], [#4141])

### Changed

- **sandbox:** The Helm chart now defaults per-sandbox Services to `ClusterIP`
  instead of `NodePort`, so the code-execution sandbox is reachable only inside
  the cluster via Service DNS (`http://sandbox-<id>-svc.<ns>.svc.cluster.local`)
  and is no longer bound on every node's interfaces - including the
  externally-reachable ones on GKE/EKS/AKS. Existing chart installs flip
  NodePort -> ClusterIP on upgrade. To preserve the old reachability (an
  external probe hitting the 30xxx port, or the Docker-Compose/hybrid path
  where the gateway is not in K8s), set `provisioner.sandboxServiceType: NodePort`
  (with `provisioner.nodeHost` if needed). The provisioner itself is unchanged
  (mode-aware since #4016). ([#4190])
- **skills:** An active restrictive skill must explicitly list `task` in
  `allowed-tools` to delegate to a subagent. Read-only discovery infrastructure
  (`tool_search` and `describe_skill`) remains available, but cannot grant schema
  visibility or execution for a denied business tool. ([#4098])
- **memory:** Pre-abstraction top-level `memory.*` DeerMem fields
  (`storage_path`, `max_facts`, `debounce_seconds`, `model_name`,
  `token_counting`, `staleness_*`, `consolidation_*`, ...) are **auto-migrated
  into `backend_config`** on load with a warning, so an upgrade does NOT silently
  revert customized settings to defaults (`model_name` ->
  `backend_config.model.model`). Move them under `memory.backend_config` in
  `config.yaml` to silence the warning. ([#4122])
- **memory:** Added `memory.mode` (`middleware` | `tool`); `tool` mode registers
  memory tools (`memory_search`/`add`/`update`/`delete`) the model calls directly
  instead of passive per-turn summarization. `manager_class` resolution is now
  fail-fast (raises `ValueError` on an unknown backend instead of silently
  falling back). ([#4023])
- **middleware:** Declarative layered middleware builder; `ThreadData` now runs
  before `Uploads`. ([#3809])
- **sandbox:** The host->virtual output-masking regex now has a single owner,
  eliminating duplicated pattern compilation. ([#4108])
- **docs:** `AGENTS.md` is now the source of truth for agent guidance, imported
  by `CLAUDE.md` via `@AGENTS.md`; module guides refreshed. ([#3770])

### Fixed

- **skills:** Apply `allowed-tools` only to slash-activated or actually loaded
  lead-agent skills, preventing passive enabled skills and evaluation fixtures
  from removing MCP, web, file, and delegation tools from every run. ([#4095],
  [#4098], [#4192])
- **models:** Honor `api_base` on every `BaseChatOpenAI` subclass (`VllmChatModel`,
  `MindIEChatModel`, `PatchedChatMiMo`, `PatchedChatStepFun`, `PatchedChatMiniMax`),
  not just `ChatOpenAI` / `PatchedChatOpenAI`. Those five previously dropped the
  configured endpoint silently and then failed every request with an opaque
  `unexpected keyword argument 'api_base'`; the unknown-config-key warning was
  disabled for them as well. Both now gate on `issubclass(BaseChatOpenAI)`.
  ([#4146])
- **agents:** Coalesce `SystemMessage`s before the LLM request; ensure a visible
  response after tool runs; avoid a default LLM title call before stream end;
  reserve ellipsis room so the local title respects `max_chars`; and snap the
  tool-output tail forward so fallback truncation respects `max_chars`. ([#3711],
  [#4033], [#3885], [#4052], [#4017])
- **agents:** Skip dateless reminders in the dynamic-context date scan; load
  `SOUL.md` from agent dirs without `config.yaml`; require `config.yaml` in
  `update_agent`'s legacy-agent guard; and refuse empty `SOUL.md` updates.
  ([#3685], [#4136], [#4166], [#4219])
- **middleware:** Window the loop-detection tool-frequency counter so long runs
  no longer false-trip; prevent the title middleware from streaming tokens;
  fix positional fallback consuming an unrelated todo when the same-content list
  is exhausted; acquire the token-budget lock across `_apply`, `before_agent`,
  `_clear_run_state`, and `_drain_pending_warnings`; drop orphan `ToolMessage`s
  so strict providers don't 400; sanitize invalid tool-call arguments; and
  recover from empty tool-call names and malformed tool-call ids in dangling
  repair. ([#4072], [#3566], [#3709], [#3714], [#4080], [#4193], [#4008],
  [#4246])
- **subagents:** Inherit `LoopDetectionMiddleware` and summarization middleware
  so tool loops break and steps are captured; surface the turn-budget cap as
  `MAX_TURNS_REACHED` with a partial result; unify guardrail caps on the additive
  `stop_reason` + `token_budget`; inject durable context before compaction;
  preserve the parent checkpoint namespace; prohibit the `task` tool in the
  general-purpose system prompt; re-buffer subagent events on flush failure to
  avoid losing steps; and fix the lost `loop_capped` stop reason when a
  subagent's `run_id` is `None`. ([#3931], [#4009], [#3949], [#3980], [#4040],
  [#4215], [#4161], [#4082], [#4059])
- **memory:** Harden against null/empty edge cases - skip whitespace-only facts;
  coerce null `confidence` / `source.confidence` in updates, searches, and the
  three remaining raw reads; treat explicit `null` `backend_config` values as
  omitted; fix `KeyError` / `UnboundLocalError` when a fact has no id or the
  facts list is empty; stop the busy-spin in the debounced update queue; and
  flush the memory queue on graceful shutdown to prevent loss. ([#3719], [#4074],
  [#4076], [#4034], [#4217], [#3993], [#3992], [#4073], [#4181])
- **runs:** Close multi-worker ownership gaps in run atomicity; degrade cancel
  to lease takeover for multi-worker; keep `create_thread` idempotent when the
  insert loses a race; read `stop_reason` from runtime context; and persist run
  duration in checkpoints for history reads. ([#4003], [#4064], [#3800], [#4188],
  [#4118])
- **runtime:** Serialize SQLite event-store writes to prevent per-thread
  sequence collisions; skip hidden human messages in the journal; and drop the
  silent delta-discard in `_merge_stream_text`. ([#4077], [#3698], [#4085])
- **gateway:** Attach thread-message feedback by real `event_type`; offload
  blocking filesystem IO in artifact serving, gateway uploads, and the Discord
  channel; limit the uploaded-file context manifest; and live-tail malformed
  Redis reconnect ids. ([#3651], [#3551], [#3935], [#3927], [#3917], [#4012])
- **uploads:** Claim the converted-Markdown companion filename before writing
  it, so two convertible uploads sharing a stem (or a convertible plus a
  same-stem `.md` upload) no longer silently clobber each other within one
  request. When `uploads.auto_convert_documents` is on, the companion `.md` now
  gets a unique name (e.g. `a_1.md`); `POST /threads/{id}/uploads` and
  `DeerFlowClient.upload_files` both report the actual name in `markdown_file`.
  ([#4288])
- **config:** Coerce null object config sections to their defaults; honor the
  unified database configuration in the store and sync checkpointer; and have
  legacy DB backfill create missing `Index` objects on existing tables. ([#3573],
  [#3904], [#3994], [#4090])
- **models:** Apply the `stream_chunk_timeout` default to all `BaseChatOpenAI`
  subclasses; and normalize `api_base` -> `base_url` for `ChatOpenAI` with a
  warning on unknown config keys. ([#4102], [#3790])
- **mcp:** Isolate tool-discovery failures per server; synchronize the
  session-pool singleton lifecycle; invalidate the tools cache on config content
  + path (not just newer mtime); validate MCP tool names at load so deferred
  prompts stay inert; and route tools by source server, not name prefix. ([#3772],
  [#3797], [#4124], [#4154], [#3812])
- **skills:** Activate a slash skill once per run, not per model call; close the
  skill-install security-scan coverage gap; recognize fully deleted skill
  packages in review CI and remaining `requests` / `httpx` methods as network
  sinks in SkillScan; reuse the resolved app config in the no-arg skills prompt
  section; and reload mounted skills without restarting the Gateway. ([#4103],
  [#3924], [#4169], [#4130], [#4160], [#4264])
- **sandbox:** Guard the reverse path-translation and output-masking regexes
  with segment boundaries; handle one-sided line ranges and empty files in
  `read_file` / `str_replace`; align the AIO bash working directory; use
  `os.sep` in the reverse-resolve containment check on Windows; normalize
  Windows backslash paths in bash commands; stop `glob` / `grep` / `ls` from
  surfacing disabled skills' files; and allow valid heredoc commands in the
  sandbox audit. ([#4035], [#4053], [#4078], [#4079], [#4051], [#4058], [#3869],
  [#4096], [#3786])
- **sandbox:** Synchronize the sandbox provider singleton lifecycle (with
  concurrency regression tests) and keep k8s calls off the event loop in the
  provisioner. ([#3730], [#3941])
- **sandbox:** Align sandbox artifact mounts with the channel user; fix
  local-dev (`make dev`) on non-root / NFS hosts; reap macOS nginx processes on
  stop; and fix production Postgres UV-extras detection in Docker. ([#3729],
  [#3590], [#3828], [#3897])
- **channels:** Validate the channel provider before resolving its config;
  dedupe GitHub webhook redeliveries and drop redundant GitHub review-comment
  webhook fan-out; scope the slash-skill whitelist check to the run's owner;
  batch Feishu file messages into one thread and dispatch Feishu group commands
  prefixed with a bot @mention; accept leading @mentions before `/connect` bind
  codes and don't treat a bare "connect" as a bind command; stop Feishu from
  creating thread topics and throttle card updates; let the UI runtime channel
  config win over `config.yaml`; fix `require_mention` gating on
  whitespace-only `bot_login` / `mention_login`; guard null quote fields in
  WeCom; and key inbound dedupe on chat-scoped workspaces so Telegram, Feishu,
  WeChat and DingTalk redeliveries stop re-running the agent on a default
  (unbound) configuration, releasing the dedupe key on transient failures so a
  redelivery can still recover. ([#4100], [#4104], [#4131], [#4129], [#3753],
  [#4229], [#4222], [#4251], [#3810], [#3674], [#4055], [#4069], [#4287])
- **frontend:** Preserve messages and durable context across summarization;
  preserve artifacts and stabilize artifact paths during streaming; resolve
  relative artifact image paths; retain presented artifacts in the header
  dropdown; keep orphan tool messages visible; show assistant text during tool
  steps; reset new chat on client-side navigation; prevent stream cancellation
  on concurrent submit; fix stale-run reconnect and cancel handling; fix chat
  math rendering, single-tilde markdown, double reasoning rendering, UTF-16
  markdown binary classification, and `<memory>` tags in Streamdown; make
  recent-chat rows fully clickable; validate attachment limits before upload and
  fix uploaded-file metadata in message copy; fix mobile workspace and
  accessibility blockers, the card tool-message bug, and side-chat toolbar /
  panel-button behavior; block unresolved suggestion-template placeholders;
  refresh notification permissions; show the branch action only for completed
  turns; enable regenerate in custom agent chats; and generate a fallback title
  for interrupted first-turn runs. ([#3826], [#3791], [#4094], [#4038], [#3854],
  [#3880], [#4114], [#3673], [#3878], [#3908], [#3557], [#4245], [#3870], [#3966],
  [#4209], [#3733], [#3900], [#3944], [#3740], [#3976], [#3959], [#3961], [#3764],
  [#3768], [#4147], [#3967], [#3874], [#3644])
- **tui:** Interrupt an active run before `/quit` exits. ([#4235])
- **harness:** Don't flag the outline as truncated at exactly `MAX_OUTLINE_ENTRIES`
  headings. ([#3856])
- **tracing:** Attach Langfuse trace metadata to the goal evaluator. ([#4202])
- **context:** Resolve the context-compress bug. ([#4065])
- **threaddata:** Fix `AttributeError` when `runtime.context` is `None`. ([#3989])
- **goal:** Stop `continuation_count` double-bump during stand-down. ([#4199])
- **circuit-breaker:** Stop wedging after a non-retriable half-open probe. ([#3991])
- **github:** Match `allow_authors` logins case-insensitively. ([#4218])
- **community:** `image_search` now returns the full-resolution image URL. ([#3990])

### Performance

- **runtime:** Index `MemoryRunStore` by `thread_id` and `MemoryRunEventStore`
  events by `run_id` to avoid O(n) scans. ([#3562], [#3686])
- **subagents:** Deduplicate streamed AI messages via a seen-id set (O(n²) ->
  O(n)). ([#3687])
- **sandbox:** Cache `LocalSandbox` path-rewrite regexes and local-path masking
  patterns per instance instead of recompiling per search match. ([#3648],
  [#3713])

### Security

- **prompt-injection:** New input-sanitization middleware defends against
  prompt-injection, forged framework tags in the input guardrail are blocked,
  and system context is injected as a `SystemMessage` for role isolation. ([#3662],
  [#4155], [#3661])
- **prompt-injection:** HTML-escape untrusted content rendered into model prompts
  - memory facts and summaries, `SOUL.md`, subagent descriptions, and the
  conversation block in the memory-update prompt - and neutralize
  prompt-injection tags in `web_capture` tool results. ([#4028], [#4119], [#4137],
  [#4157], [#4162], [#4099], [#4060])
- **secrets:** Scrub inherited secret environment variables (`MYSQL_PWD`,
  `REDISCLI_AUTH`, abbreviated `*_PASS`, and Postgres `PGPASSFILE`) from the
  skill environment; request-scoped secrets are bound for both slash-activated
  and autonomously-invoked skills. ([#4018], [#4026], [#3871], [#3938])
- **web_fetch:** SSRF guard for self-hosted providers. ([#3942])
- **guardrails:** An empty allowlist now denies all tools instead of failing
  open. ([#4067])
- **authz:** Global skills-management endpoints now require admin; the legacy
  skills mount is gated by user visibility; artifacts honor a trusted
  `owner-user-id` header; and the trusted authorization principal is propagated
  through the runtime. ([#3855], [#3985], [#3982], [#4203])
- **auth:** Persist the `csrf_token` cookie for the access-token lifetime.
  ([#3872])
- **storage:** Stop persisting base64 image data in checkpoint state. ([#4140])

## [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])
- **auth:** Reject cross-site auth POSTs. ([#2740])
- **gateway:** Cap skill artifact preview decompression to prevent
  zip-bomb-style abuse. ([#2963])
- **sandbox:** Mount the host Docker socket only in aio (DooD) sandbox mode.
  ([#3517])
- **sandbox:** Do not bind-mount host CLI auth dirs by default. ([#3521])

### Fixed

#### Runtime, gateway & persistence
- **runtime:** Rollback restore checkpoint now supersedes newer checkpoints.
  ([#2582])
- **runtime:** Persist run message summaries. ([#2850])
- **runtime:** Bound `write_file` execution-failure observations to keep
  failure traces from blowing out the context. ([#3133])
