- fix(langchain): keep tool call streams pending across any tool
interrupt</p>
<p>A raw <code>interrupt()</code> raised from inside a tool surfaced as
a <code>tool-error</code> and
rejected the call's un-awaited <code>output</code> promise, producing an
unhandled
rejection that crashed HITL runs. The tool-call stream transformer now
treats
any serialized graph interrupt as control flow (the call stays pending
and
resumes), not just <code>humanInTheLoopMiddleware</code> interrupts.</p>

<p>Add a native subagent stream transformer to <code>createAgent</code>
so v3 runs expose
named nested agents (<code>createAgent({ name })</code> invoked from
tools) as typed
<code>SubagentRunStream</code> handles with <code>name</code>,
<code>cause</code>, scoped <code>messages</code> /
<code>toolCalls</code>, and <code>output</code>. Refactors agent stream
transformers into
<code>agents/transformers/</code> and exports only the public stream

fix(openai): omit empty id and content on reasoning items in Responses
API input</p>
<p>Reasoning blocks reassembled from streaming chunks (e.g. via
<code>streamEvents</code>) never carry an id, since OpenAI's streaming
protocol only includes it in non-streaming responses. When such a
message was replayed as Responses API input on the next turn, the
reasoning item was emitted with <code>id: &quot;&quot;</code>, which
OpenAI rejects with <code>400 Invalid 'input[n].id': ''</code>. The
<code>id</code> field is now omitted when absent.</p>
<p>A second error surfaced immediately after that fix: the same
converter set a populated <code>content</code> array on the reasoning
input item, which the Responses API also rejects (<code>400 Invalid
'input[n].content': array too long. Expected an array with maximum
length 0</code>). Reasoning input items only carry <code>summary</code>,
so <code>content</code> is no longer forwarded. Thanks to <a
href="https://github.com/csrujanreddy"><code>@​csrujanreddy</code></a>
for catching the second issue and verifying both fixes against the live
API.</p>

Tighten the <code>@langchain/core</code> peer dependency to

<code>utils/standard_schema</code> and
<code>language_models/structured_output</code> export subpaths imported
by <code>ChatGroq</code>. The previous <code>^1.0.0</code> range allowed
core versions below 1.1.30 that lack these exports, causing

fix(langgraph): drop unused zod-to-json-schema peer dependency

Remove the vestigial `zod-to-json-schema` (and its
`peerDependenciesMeta`/dev) declarations. JSON Schema generation now
flows through `@langchain/core`'s Zod v3/v4 interop (`toJsonSchema`), so
the old `zod-to-json-schema@^3.x` peer (which pins `zod@^3.24.1`) is no
longer needed and was the last source of install-time peer conflicts
with Zod v4. Closes
[#1706](https://github.com/langchain-ai/langgraphjs/issues/1706).

fix(langgraph-checkpoint-postgres): prevent createAgent failures with
PostgresSaver

Add BaseCheckpointSaver.toJSON() so ConfigurableModel can stringify
runnable config without traversing pg Pool timers, and default missing
checkpoint maps on load/copy so resume no longer crashes on undefined
versions_seen. Closes
[#1808](https://github.com/langchain-ai/langgraphjs/issues/1808).

fix(langgraph-checkpoint-postgres): prevent createAgent failures with
PostgresSaver

Add BaseCheckpointSaver.toJSON() so ConfigurableModel can stringify
runnable config without traversing pg Pool timers, and default missing
checkpoint maps on load/copy so resume no longer crashes on undefined
versions_seen. Closes
[#1808](https://github.com/langchain-ai/langgraphjs/issues/1808).

fix(langgraph-api): support configurable TypeScript loaders in dev
server

Add `node_loader` to `langgraph.json` (and `LANGGRAPH_NODE_LOADER` env
override) so projects using reflect-metadata can use `ts-node`
(`--loader ts-node/esm`) instead of the default tsx CLI. Other loaders
default to `--import`; only registered shorthands like `ts-node` use
`--loader`. `--no-reload` now also disables tsx's internal watch mode.

fix(langgraph): emit valid UUIDs for exit-mode delta task_ids

Exit-mode DeltaChannel writes used a step-prefixed synthetic task id
that produced a 6-segment string Postgres rejects for
`checkpoint_writes.task_id uuid` in LangGraph API. Embed the superstep
in the first UUID group instead, matching langchain-ai/langgraph#8165.

fix(sdk): bundle pure-ESM deps into CJS build to fix ERR_REQUIRE_ESM

Bundle the pure-ESM dependencies `p-retry` and `p-queue` (and their
transitive ESM-only deps) into the build output so the CJS artifact no
longer does a top-level `require()` of an ESM module. This fixes
`ERR_REQUIRE_ESM` for CommonJS consumers on Node versions where
`require(ESM)` is not enabled by default (&lt; 20.19 / &lt; 22.12).

github-actions[bot] 31261c3be5 chore: version packages (#2558) 
This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.


# Releases
## @langchain/langgraph-checkpoint-mongodb@1.4.0

### Minor Changes

- [#1928](https://github.com/langchain-ai/langgraphjs/pull/1928)
[`3d7fcea`](https://github.com/langchain-ai/langgraphjs/commit/3d7fcea7d7ea7f1203d24be9df607d5a8e8717bc)
Thanks [@Mihailoff](https://github.com/Mihailoff)! - Add TTL support for
automatic checkpoint expiration

    -   Add optional `ttl` parameter to MongoDBSaver (value in seconds)
    -   Add `setup()` method to create TTL indexes on collections
    -   Add `upserted_at` timestamp to documents when TTL is enabled
- Each write refreshes TTL (expires after inactivity, not creation)

### Patch Changes

- [#2556](https://github.com/langchain-ai/langgraphjs/pull/2556)
[`bee3c91`](https://github.com/langchain-ai/langgraphjs/commit/bee3c91d0adc315ebde0622d8c4b1fff041c1bfd)
Thanks [@mohamedkhaled4053](https://github.com/mohamedkhaled4053)! - Fix
`MongoDBSaver.putWrites` throwing `MongoServerError: Invalid
BulkOperation, Batch cannot be empty` when called with an empty `writes`
array. This is reached by human-in-the-loop / `interrupt()` flows, where
a task can complete producing zero channel writes and LangGraph calls
`putWrites(config, [], taskId)`. `putWrites` now no-ops on empty writes,
matching the behavior of the postgres and sqlite savers (which iterate
and naturally skip empty batches).

fix(langgraph-api): preserve non-empty response_metadata on protocol-v2
state messages

The protocol-v2 state normalizer stripped `response_metadata` from
messages,
dropping data that HITL flows rely on — an interrupt's card is carried
on
    `AIMessage.response_metadata` (e.g. `{ cards: ... }`). Non-empty
    `response_metadata` is now retained so the card reaches the client.

fix(sdk): apply state update and goto alongside interrupt resume

    `respond(decision, { update, goto })` now maps to LangGraph's
`Command(resume, update, goto)`, so a human-in-the-loop UI can commit a
state
update (e.g. push the interrupt card into state) in the **same
superstep** as
the resume — one checkpoint, no separate `updateState` write, no
flicker.
`@langchain/langgraph-api` forwards `update`/`goto` through
`input.respond`,
and `@langchain/core` message instances in `update` are serialized to
dicts
before transport, exactly like `submit()`. Bumps `@langchain/protocol`
to
    `^0.0.18` for the `Goto` type.

`respond`/`respondAll` also apply `update` **optimistically** (mirroring
`submit()`): the pushed messages paint immediately, with stable ids
minted so
the resumed run's echo reconciles them in place. Without this the
interrupt is
cleared the instant `respond()` dispatches while the pushed card only
reappears
a server round-trip later — so the card would flicker in that gap. The
optimistic state settles on the resumed run's terminal (pending → sent,
or
    rolled back on a failure before any echo).

User-initiated optimistic writes (`submit()` / `respond()` /
`respondAll()`) now
commit to the store **synchronously**, in the same tick as the
triggering event,
instead of being coalesced onto the next macrotask. This lets a
framework render
the pushed message in the **same commit** as any local UI state the
caller flips
alongside it (e.g. a HITL form swapping its inputs for the resolved
card), so the
card no longer blinks out for the one-macrotask window before the flush
lands.
    High-frequency streaming writes keep their macrotask coalescing.

fix(sdk): apply state update and goto alongside interrupt resume

    `respond(decision, { update, goto })` now maps to LangGraph's
`Command(resume, update, goto)`, so a human-in-the-loop UI can commit a
state
update (e.g. push the interrupt card into state) in the **same
superstep** as
the resume — one checkpoint, no separate `updateState` write, no
flicker.
`@langchain/langgraph-api` forwards `update`/`goto` through
`input.respond`,
and `@langchain/core` message instances in `update` are serialized to
dicts
before transport, exactly like `submit()`. Bumps `@langchain/protocol`
to
    `^0.0.18` for the `Goto` type.

`respond`/`respondAll` also apply `update` **optimistically** (mirroring
`submit()`): the pushed messages paint immediately, with stable ids
minted so
the resumed run's echo reconciles them in place. Without this the
interrupt is
cleared the instant `respond()` dispatches while the pushed card only
reappears
a server round-trip later — so the card would flicker in that gap. The
optimistic state settles on the resumed run's terminal (pending → sent,
or
    rolled back on a failure before any echo).

fix(langgraph): isolate concurrent singleton-agent invocations by thread

`ensureLangGraphConfig` ignores the ambient `AsyncLocalStorage`
`configurable`
on root-level invokes that supply an invoke-time `thread_id` and have no
nesting
keys (ignoring graph-bound `.withConfig()` defaults). On a fresh
top-level run
the ambient `configurable` can belong to another concurrent invocation,
so its
    keys — internal scratchpad/task-input as well as user keys like
`tenant_id`/`user_id` — must not leak in; values the caller wants arrive
through
the explicit (bound + invoke-time) configs. Ambient nesting
(`__pregel_read__`)
and bound child graphs invoked from parent tasks are unaffected. This
prevents
cross-invocation leakage between concurrent `invoke()` calls on a shared
compiled
graph (e.g. BullMQ workers with `concurrency > 1`). Complements the
config-merge
fix that stopped shared graph-bound `metadata`/`configurable` objects
from being
    mutated across invocations
    ([#2040](https://github.com/langchain-ai/langgraphjs/issues/2040)).

fix(langgraph): recognize JSON-erased `Overwrite` values across runtimes

`Overwrite` already survives JSON serialization in JS because
`Overwrite.toJSON()`
emits the canonical `{ "__overwrite__": value }` sentinel.
`_getOverwriteValue`
now additionally recognizes the discriminator form `{ "type":
"__overwrite__",
value }` produced when a typed `Overwrite` from another runtime (e.g. a
Python
dataclass routed through the LangGraph API server) is serialized and its
type is
erased. This keeps `Overwrite` (and `DeltaChannel`) semantics intact
across
cross-runtime JSON boundaries. These delta-channel APIs remain Beta.

fix(langgraph): make concurrent DeltaChannel writes deterministic on
replay

Concurrent same-superstep writes to a `DeltaChannel` could reconstruct
from a
checkpoint differently than they were applied live, because live
execution
ordered them by task path while savers replayed them by task id. This
fixes that
    divergence in two complementary ways:

- Plain concurrent writes are now applied in the canonical `(task_id,
idx)`
order on both paths: `_applyWrites` orders them that way live, and the
`getDeltaChannelHistory` walk enforces the same order so reconstruction
matches live for every saver (Postgres, SQLite, MongoDB, Redis, and
custom).
- An `Overwrite` now wins its entire super-step: every sibling write in
the same
        step — before AND after the `Overwrite` — is discarded, matching
`BinaryOperatorAggregate`. This makes the result independent of the
(unstable)
ordering of concurrent fan-in writes; previously a plain write that
landed
        after an `Overwrite` in the same step was still folded in.

To keep reconstruction in sync with this `Overwrite` rule, any
`DeltaChannel`
that sees an `Overwrite` in a super-step is now force-snapshotted at the
next
checkpoint (and, under `"exit"` durability, in the final checkpoint).
The
post-overwrite value is materialized into `channel_values`, so a cold
read seeds
from that snapshot and never has to replay across the reset — making
live and
reconstructed state identical without changing the sparse-replay history
shape.
    These delta-channel APIs remain Beta.

fix(langgraph): forward task metadata and name subagents via
lc_agent_name

`mapDebugTasks` now forwards filtered user-meaningful task config
metadata
(including `lc_agent_name`) onto `tasks` stream payloads. The lifecycle
    transformer uses that metadata to set subagent `graph_name` from
`lc_agent_name` and recover `cause: { type: "toolCall", tool_call_id }`
from parent tool-dispatch tasks. Adds the shared
`EXCLUDED_METADATA_KEYS`
    constant to `@langchain/langgraph-checkpoint`. Ports langgraph#7928.

fix(langgraph-checkpoint-redis): persist and reconstruct full
`channel_values` across multi-node graphs.

`RedisSaver.put()` delta-filters `channel_values` to only the channels
written by the current node, but `getTuple()` had no reconstruction
logic — unlike `PostgresSaver` — so any multi-node graph whose last node
wrote a subset of channels silently lost the others. Each changed
channel is now persisted as a version-keyed `checkpoint_blob:*` entry in
`put()` and missing channels are reconstructed from those blobs on read.

`deleteThread()` now also deletes the `checkpoint_blob:*` keys. Without
this the blobs introduced above would orphan forever (memory growth) and
thread deletion would be incomplete, matching
`PostgresSaver.deleteThread()` parity.

When `ttlConfig.refreshOnRead` is enabled, reads now refresh the TTL of
the reconstructed `checkpoint_blob:*` keys alongside the checkpoint key.
Otherwise a read would keep the checkpoint alive while the blobs it
depends on expired, silently dropping reconstructed channels.

On write, `put()` now refreshes the TTL of every blob the checkpoint
references (the full `channel_versions` set), not just the channels
changed by the current node, so carried-over blobs from earlier nodes
expire in lockstep with the checkpoint doc. This write-side refresh is
independent of `refreshOnRead`. The per-channel blob writes also now run
in parallel.

Known limitation: with TTL enabled, a carried-over blob can still be
lost if it expires during an idle gap longer than `defaultTTL` (no read
or write refreshed it in time). When that happens the channel is left
cleanly absent on read rather than erroring. Fully closing this gap
(re-persisting expired blobs) is tracked as a follow-up.

fix(langgraph): merge instead of overwrite in `ensureLangGraphConfig`

`ensureLangGraphConfig` now per-key merges `callbacks`, `tags`,
`metadata`,
and `configurable` across configs instead of last-write-wins, so values
bound via `.withConfig({...})` survive when a later (e.g. invoke-time)
config supplies other keys. The merged dicts are fresh objects, fixing a
by-reference mutation of shared base configs. Also drops the
now-redundant
`combineCallbacks` workaround in `streamEvents`, which double-registered
and
    double-fired graph-bound callbacks.

fix(langgraph): preserve namespace nesting for imperative graph invokes

When a compiled graph is invoked from inside another graph's running
task
(e.g. a tool body calling `subAgent.invoke(...)`), the surrounding task
context — including the langgraph-internal nesting keys
(`__pregel_read`,
`__pregel_stream`, `checkpoint_ns`, the checkpoint map) — is propagated
    implicitly via `AsyncLocalStorage`. The base `Runnable.stream` calls
langchain-core's `ensureConfig`, which replaces the ambient
`configurable`
wholesale whenever the caller passes its own. Because `createAgent`
always
supplies a `configurable`, every tool-invoked sub-agent lost those keys,
ran
as a fresh root run, and had its streamed events flattened to the root
    namespace instead of nesting under the triggering task.

`Pregel.stream` now merges the ambient `configurable` underneath the
caller's
    (caller keys win per-key) when the ambient marks an active task
(`__pregel_read` present) but the explicit `configurable` is missing it.
Declared subgraph nodes (which already carry their own `__pregel_read`)
and
    top-level runs are unaffected.

fix(langgraph): dispatch stream messages handler inline

The v3 `messages` handler (`StreamProtocolMessagesHandler`, which powers
`run.messages`) only performs a synchronous `push()` onto the run's
stream, but
its callbacks were dispatched on LangChain's background callback queue
(the
default `awaitHandlers === false`). A model or tool call inside a nested
or
parallel task could therefore flush its `messages` chunk _after_ the
Pregel
loop returned and sealed the stream, where
`IterableReadableWritableStream.push`
silently drops chunks once closed. This surfaced as empty per-message
streams
(`sub.messages`) for subagents dispatched in parallel from a single
tools step.

The handler now sets `awaitHandlers = true` so its callbacks run inline
— every
push happens during the originating model/chain call while the stream is
still
open. This avoids the global over-wait, fake-timer deadlock, and
error-path
unhandled rejections that a blanket `awaitAllCallbacks()` drain before
close
    would have introduced.

fix(langgraph): support DeltaChannel fields in StateSchema

Add a `DeltaValue` state field (and a `MessagesDeltaValue` prebuilt) so
a
`DeltaChannel` can be declared via `StateSchema`, not just
`Annotation.Root` or
a raw channel map. `StateSchema` now maps `DeltaValue` to a
`DeltaChannel`
(forwarding `snapshotFrequency` and the value-schema default) and
validates its
    inputs/`Overwrite` updates like `ReducedValue`.

fix(sdk): avoid scoped stream resubscribe churn

Defer final projection disposal by one microtask so framework bindings
that release and immediately reacquire the same scoped projection during
reactive updates keep the existing stream subscription instead of
rotating through root-only and scoped SSE filters.

chore(deps): remove uuid dependency in favor of embedded uuid in core

Replace direct `uuid` package imports with `@langchain/core/utils/uuid`
across
langgraph packages to deduplicate dependencies and align with
@langchain/core's
    embedded UUID utilities.

## @langchain/langgraph-checkpoint-redis@1.0.9

### Patch Changes

- [#2525](https://github.com/langchain-ai/langgraphjs/pull/2525)
[`829a32a`](https://github.com/langchain-ai/langgraphjs/commit/829a32a30cc22103b1cb0aba6a027b7ccdb68447)
Thanks [@lhlyu](https://github.com/lhlyu)! - Fix Redis checkpoint
pending write deserialization when a write document has no `value`
field. RedisJSON omits `undefined` values, so `loadPendingWrites` now
restores a missing `value` as `undefined` instead of passing it through
JSON parsing.

fix(sdk): reconnect SSE streams when heartbeat idle is detected

Detect half-open SSE connections by watching for server keep-alive
heartbeats (`: heartbeat`) and reconnecting with Last-Event-ID or
`since` when they stop. `"auto"` mode arms only after heartbeats are
observed, so long tool calls and HITL pauses do not false-fire on
heartbeat-emitting servers.

[`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Allow custom `AgentServerAdapter`s to be late-bound and re-bound to a
thread. Adapters can now implement an optional `setThreadId(threadId)`,
which `client.threads.stream(threadId, { transport })` calls when
binding the active thread — including the lazily-minted id from the
first `submit()` on a `threadId: null` controller. The built-in
`ProtocolSseTransportAdapter`, `ProtocolWebSocketTransportAdapter`, and
`HttpAgentServerAdapter` implement it: `threadId` is now optional at
construction, request URLs derive from the currently-bound thread, and
`paths` entries may be functions of the thread id (`(threadId) =>
string`). This lets a single custom transport back a lazy
thread-creation flow instead of being pinned to one thread at
construction.

# Releases
## @langchain/langgraph-supervisor@1.1.0

### Minor Changes

- [#2521](https://github.com/langchain-ai/langgraphjs/pull/2521)
[`56682a6`](https://github.com/langchain-ai/langgraphjs/commit/56682a69a24d0dfb210f1fb5187c51e3adc356bf)
Thanks [@open-swe](https://github.com/apps/open-swe)! -
feat(langgraph-supervisor): Add `addHandoffMessages` to
`createSupervisor` and `createHandoffTool`, allowing supervisor-to-agent
handoff bookkeeping messages to be omitted from the expert agent's
message history. When `addHandoffBackMessages` is not provided, it now
defaults to the same value as `addHandoffMessages`, matching the Python
package behavior.

`createHandoffTool` now also accepts `description` as the preferred
option name while continuing to support the existing `agentDescription`
option as deprecated for backwards compatibility.

### Patch Changes

- [#2407](https://github.com/langchain-ai/langgraphjs/pull/2407)
[`59d4765`](https://github.com/langchain-ai/langgraphjs/commit/59d4765870bc0cddf3ef594b128ab3280533cb6c)
Thanks [@pragnyanramtha](https://github.com/pragnyanramtha)! - Normalize
all whitespace in supervisor handoff tool names.

## @langchain/langgraph@1.4.1

### Patch Changes

- [#2520](https://github.com/langchain-ai/langgraphjs/pull/2520)
[`2da5c33`](https://github.com/langchain-ai/langgraphjs/commit/2da5c3374f7b91ba0afa607c507e2ff1591baca7)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(state): validate Zod state updates from nodes

Validate node return values and Command updates against Zod state schema
    constraints before applying them to graph state.

Fixes [#2519](https://github.com/langchain-ai/langgraphjs/issues/2519)

- [#2511](https://github.com/langchain-ai/langgraphjs/pull/2511)
[`ef04db3`](https://github.com/langchain-ai/langgraphjs/commit/ef04db316d680ab32b812c88cadda75638294dd3)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
feat(ToolNode): forward graph state to tools via `runtime.state`

`ToolNode` now forwards its input to each tool through the second
argument as `runtime.state`. When using `ToolNode` as a node in a
LangGraph graph, this gives tools access to the current graph state for
workflows that need tool-call support in LangGraph proper. Tools can
type the second parameter as `ToolRuntime<StateType>` from
`@langchain/core/tools` and read `runtime.state` directly. This works in
every runtime, including web browsers, and removes the need for
`getCurrentTaskInput()` (which relies on
`node:async_hooks`/`AsyncLocalStorage`). `getCurrentTaskInput(config)`
continues to work for backwards compatibility.

[`3855985`](https://github.com/langchain-ai/langgraphjs/commit/3855985dd049739f145295d236ce6aa02ae2fb0e)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
feat(stream): add per-event side-effect selector

Add `useChannelEffect` (React/Svelte/Vue) / `injectChannelEffect`
(Angular), a side-effect counterpart to `useChannel` that invokes an
`onEvent` callback once per raw protocol event without re-rendering.
This is the idiomatic v1 replacement for the old `onLangChainEvent` /
`onCustomEvent` callbacks for analytics and logging. Backed by a new
framework-agnostic `acquireChannelEffect` helper in
`@langchain/langgraph-sdk/stream` that shares a ref-counted subscription
with matching `useChannel` consumers.

- [#2523](https://github.com/langchain-ai/langgraphjs/pull/2523)
[`7c3e9e9`](https://github.com/langchain-ai/langgraphjs/commit/7c3e9e93f3c7ec1dc654dac8ee8c03562ee8337b)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(sdk): stop re-streaming seeded messages on idle-thread submit

An idle (finished) thread defers its root SSE pump, so the first
`submit()` brings it up and the transport replays the finished run from
`seq=0`. The replayed `messages` channel carries no step (unlike
`values`, guarded by `maxStep`), so it rebuilt each already-complete
message from an empty `message-start` and re-streamed the whole turn
token-by-token — a visible "messages replay" of the existing
conversation. Seal the message ids seeded from the idle `getState()`
snapshot so replayed deltas can't downgrade the complete tail; the seal
lifts once a newer checkpoint advances the timeline or on thread rebind,
and ids from the next run are never sealed.

- [#2462](https://github.com/langchain-ai/langgraphjs/pull/2462)
[`17c44a3`](https://github.com/langchain-ai/langgraphjs/commit/17c44a38b7478e2bc4fe908a54c78ef33fb68ba3)

transports,
wire `AsyncCaller` through `client.threads.stream`, and expose optional
reconnect tuning on `ThreadStreamOptions`. Includes integration tests
against
    an in-process mock langgraph-api server.

feat(stream): add per-event side-effect selector

Add `useChannelEffect` (React/Svelte/Vue) / `injectChannelEffect`
(Angular), a side-effect counterpart to `useChannel` that invokes an
`onEvent` callback once per raw protocol event without re-rendering.
This is the idiomatic v1 replacement for the old `onLangChainEvent` /
`onCustomEvent` callbacks for analytics and logging. Backed by a new
framework-agnostic `acquireChannelEffect` helper in
`@langchain/langgraph-sdk/stream` that shares a ref-counted subscription
with matching `useChannel` consumers.

# Releases
## @langchain/langgraph-checkpoint@1.1.0

### Minor Changes

- [#2452](https://github.com/langchain-ai/langgraphjs/pull/2452)
[`a8e7659`](https://github.com/langchain-ai/langgraphjs/commit/a8e7659a9d22fd84425aaf26bda88667c76b185a)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
`DeltaChannel` and the writes-history saver API (beta).

`DeltaChannel` is a reducer channel that stores only a sentinel in
checkpoint
blobs instead of the full accumulated value, reconstructing state on
read by
replaying ancestor writes through a batch reducer. This avoids
re-serializing
the entire accumulated value at every step (e.g. long message
histories).

- `DeltaChannel(reducer, { snapshotFrequency })` in
`@langchain/langgraph` —
count-based snapshot cadence (default `snapshotFrequency=1000`) plus a
system bound `DELTA_MAX_SUPERSTEPS_SINCE_SNAPSHOT` (default 5000, env
        `LANGGRAPH_DELTA_MAX_SUPERSTEPS_SINCE_SNAPSHOT`).
- `messagesDeltaReducer` — a batching-invariant messages reducer that
coerces
        raw object/string writes, for use with `DeltaChannel`.
- `BaseCheckpointSaver.getDeltaChannelHistory({ config, channels })`
(beta) —
walks the parent chain returning per-channel `{ writes, seed? }`, with a
        direct-storage override in `MemorySaver`.
- `counters_since_delta_snapshot` added to `CheckpointMetadata`;
`DeltaSnapshot`
        serialization support in the JSON+ serializer.

Reconstruction is wired through the Pregel read/execution paths
(initialization,
`getState`, `updateState`, local reads) and `exit` durability
accumulates and
anchors delta writes so threads remain reconstructible without forcing
    snapshots.

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
node-level timeouts.

A `timeout` option is now supported on `StateGraph.addNode`, the
functional API
(`task`/`entrypoint`), and the `Send` constructor. Pass a number of
milliseconds
    for a hard wall-clock cap, or a `TimeoutPolicy` for finer control:

    ```ts
    import { TimeoutPolicy } from "@langchain/langgraph";

    // hard wall-clock cap on each attempt
    builder.addNode("agent", agentFn, { timeout: 60_000 });

    // full control
    builder.addNode("agent", agentFn, {
      timeout: {
        runTimeout: 60_000, // hard wall-clock cap, never refreshed
        idleTimeout: 10_000, // cap on time without observable progress
        refreshOn: "auto", // "auto" | "heartbeat"
      },
    });

    // per-task override
    new Send("agent", state, { timeout: { idleTimeout: 5_000 } });
    ```

    When a timeout fires, a `NodeTimeoutError` (carrying `node`, `kind`
(`"run"`/`"idle"`), `timeout`, `elapsed`, `runTimeout`, `idleTimeout`)
is raised,
the attempt's buffered writes are dropped, and the node's `AbortSignal`
is
aborted. `idleTimeout` is refreshed by observable progress (writes,
custom
stream-writer calls, child-task scheduling, callback events) or an
explicit
    `runtime.heartbeat()` call. The timer resets per retry attempt, and
    `NodeTimeoutError` is retryable under the default retry policy.

### Minor Changes

- [#2449](https://github.com/langchain-ai/langgraphjs/pull/2449)
[`d12d269`](https://github.com/langchain-ai/langgraphjs/commit/d12d2693308e37951266bc8197daa656daa6e2aa)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
cooperative, between-superstep graph draining via `RunControl`.

    A new `RunControl` (exported from `@langchain/langgraph`) exposes
`requestDrain(reason)` plus read-only `drainRequested` / `drainReason`.
Pass it
through the new `control` option on `invoke` / `stream` / `streamEvents`
(and the
functional API). It is surfaced on `runtime.control`, so nodes can read
it or call
    `requestDrain()` themselves, and it is propagated into subgraphs.

When a drain is requested, the Pregel loop checks the flag at the top of
each
superstep (after the previous step's writes are applied and
checkpointed): if more
tasks remain it saves the checkpoint and throws the new `GraphDrained`
error (also
under `durability: "exit"`), so the run can be resumed later from the
same config.
If the graph naturally finishes on that tick it returns normally and the
caller can
inspect `control.drainRequested`. A drain requested inside a subgraph
bubbles up and
stops the parent at its next boundary. Draining never cancels work that
is already
running — pair it with an `AbortSignal` if you need a hard upper bound.

feat(langgraph): add node-level error handlers

`StateGraph.addNode(name, fn, { errorHandler })` now accepts a
first-class
node-level error handler. The handler runs ONLY after the failing node's
`retryPolicy` is exhausted, so retry and handling stay decoupled. It
receives a
typed `NodeError { node, error }` and the typed node input state, can
return a
state update, and can route to a recovery branch via `new Command({ goto
})`
    (saga / compensation flows).

Failure provenance is checkpointed (via a reserved `ERROR_SOURCE_NODE`
write) so
handlers observe the same context after a checkpoint resume. Uncaught
node
errors without a handler still abort the run as before, and
`GraphBubbleUp`
    errors (such as `interrupt()`) are never swallowed by a handler.

`StateGraph.setNodeDefaults({ errorHandler })` now also accepts a
graph-wide
default handler. It is materialized at `compile()` as a single shared
handler
and invoked for every regular node that does not set its own
`errorHandler`. A
per-node handler always takes precedence, the default never catches a
failure
raised by an error-handler node itself (handler failures fail the run),
and the
    default is not inherited by subgraphs.

    Ports the Python feature from langchain-ai/langgraph#7233.

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
`StateGraph.setNodeDefaults()` for setting graph-wide node policy
defaults (`retryPolicy`, `cachePolicy`). Per-node values passed to

`compile()` time so call order does not matter. Defaults are not
inherited by subgraphs. Ports Python's `set_node_defaults()`

perf(core): index pending writes for O(1) task-prep lookups

Build a PendingWritesIndex once per \_prepareNextTasks call so resume
and
skip-done-task checks avoid repeated linear scans over
checkpointPendingWrites.

`MongoDBSaver.putWrites` now honors `WRITES_IDX_MAP`, pinning special
channels (`__error__`, `__scheduled__`, `__interrupt__`, `__resume__`)
to fixed negative indices instead of the call-local ordinal. Previously
a mixed `putWrites([[...regular...], [INTERRUPT, …]], taskId)` placed
the INTERRUPT at a positive idx that could collide with a regular write
at the same `(task_id, idx)`, and the unconditional `$set` upsert
silently overwrote whichever row landed there first. The
conflict-resolution clause now matches the Postgres / SQLite (TS and
Python) checkpointers: `$set` only when every channel is a special one,
`$setOnInsert` otherwise.

[`375c73f`](https://github.com/langchain-ai/langgraphjs/commit/375c73fcd1ef06145301df80466fda35c0a99385)
Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix: reject SQL
`LIKE` wildcards (`%`, `_`) and the backslash escape character in
`PostgresStore` namespace labels. `BaseStore.search()` matches
namespaces via `namespace_path LIKE ${prefix}%`, and these characters in
caller-supplied namespace labels are interpreted as wildcards by
Postgres even through a bound parameter — letting a namespace prefix of
`["%"]` match every namespace in the store across tenants.
`validateNamespace` now throws for these characters at all `search` /
`get` / `put` entrypoints, keeping store-wide consistency. CWE-1336.

Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix:
`RedisSaver.putWrites` now honors `WRITES_IDX_MAP`, pinning special
channels (`__error__`, `__scheduled__`, `__interrupt__`, `__resume__`)
to fixed negative indices in their Redis key
(`checkpoint_write:…:<idx>`) instead of the call-local ordinal.
Previously a mixed `putWrites([[…regular…], [INTERRUPT, …]], taskId)`
placed the INTERRUPT key at the positive idx of its position in the
batch, where a peer task's regular write at the same idx would overwrite
it via the unconditional `JSON.SET`. The conflict-resolution clause now
matches Postgres / SQLite / MongoDB: unguarded `JSON.SET` when every
write is a special channel, `JSON.SET … NX` (insert-or-ignore)
otherwise.

`SqliteSaver.putWrites` now honors `WRITES_IDX_MAP`, pinning special
channels (`__error__`, `__scheduled__`, `__interrupt__`, `__resume__`)

a follow-up `putWrites([[INTERRUPT, …]], taskId)` for the same
checkpoint silently `REPLACE`d the regular write previously stored at
`idx=0` for that task, losing data. The conflict-resolution clause also
now matches the Python checkpointer contract: `OR REPLACE` only when
every channel is a special one (so e.g. INTERRUPT→RESUME state
transitions overwrite), `OR IGNORE` otherwise.

fix: make AnyStream a true supertype so selector hooks need no cast

    A concrete `useStream<typeof agent>()` handle was not assignable to
    `AnyStream` because generic-computed covariant members (`toolCalls`,
`values`) don't widen under `any` — `InferToolCalls<any>[]` resolves to
`AssembledToolCall<…, never>[]`, narrower than a concrete handle.
Override
    those members with their widest forms (preserving each framework's
reactivity wrapper — plain arrays for React/Svelte, `ShallowRef` for
Vue,
`Signal` for Angular) so the message/tool/value selector hooks accept a
    fully-typed stream without an `as AnyStream` cast.

fix(sdk): hydrate custom HttpAgentServerAdapter via transport getState

StreamController now prefers adapter getState() before
client.threads.getState,
HttpAgentServerAdapter implements GET /threads/:id/state, and useStream
inherits
apiUrl from the transport so hydration no longer defaults to
localhost:8123.

fix(langgraph-checkpoint-validation): align node engine with vitest

## @langchain/langgraph-api@1.3.0

### Minor Changes

- [#2505](https://github.com/langchain-ai/langgraphjs/pull/2505)
[`cad31b4`](https://github.com/langchain-ai/langgraphjs/commit/cad31b42f001a87fcdf57c4c084c655c8762b6a5)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Consolidate the protocol session's channel inference, channel-set
validation, and namespace prefix matching onto the shared
`@langchain/langgraph/stream` helpers instead of maintaining local
copies. This removes duplicated logic across `session/index.mts`,
`session/namespace.mts`, `session/internal-types.mts`, and
`service.mts`.

This also aligns SSE event-sink filtering (`matchesSinkFilter`) with the
WebSocket subscription matcher: both now normalize dynamic namespace
suffixes (e.g. a `["fetcher"]` namespace filter matches an event emitted
under `["fetcher:<uuid>"]`). Previously the SSE path used a stricter
exact-segment match.

Because the session now imports `@langchain/langgraph/stream`, the
`@langchain/langgraph` peer dependency floor is raised to `^1.3.6` (the
first release that ships the `/stream` entrypoint).

### Patch Changes

-   Updated dependencies \[]:
    -   @langchain/langgraph-ui@1.3.0

## @langchain/langgraph-checkpoint-sqlite@1.0.2

### Patch Changes

[`e8a0940`](https://github.com/langchain-ai/langgraphjs/commit/e8a09409ac4a997012e78081160c91188ebe39fc)
Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix:
`SqliteSaver.list({}, { filter })` now honors arbitrary metadata keys
(e.g. `tenant_id`, `env`), matching the behavior of the MongoDB,
Postgres, and Redis checkpointers. Previously only `source`, `step`, and
`parents` were honored — any other key was silently dropped, returning
unfiltered results.

[`cad31b4`](https://github.com/langchain-ai/langgraphjs/commit/cad31b42f001a87fcdf57c4c084c655c8762b6a5)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the `@langchain/langgraph/stream` entrypoint — a transport-agnostic
backend toolkit for building custom servers on top of the v2 streaming
protocol. Alongside the existing `StreamChannel` and
`convertToProtocolEvent`, it exposes subscription primitives, typed
against a minimal `MatchableEvent` shape so they work on both the core
`ProtocolEvent` and the wire-level `Event` from `@langchain/protocol`:

- `inferChannel(event)` — map an event to its subscription `Channel`
(named `custom:<name>` channels included).
- `matchesSubscription(event, definition)` — decide whether a buffered
event should be delivered for a `SubscribeParams` filter, honoring
channel, namespace prefix/depth, and an optional `since` replay cursor.
- `isPrefixMatch(namespace, prefix)` /
`normalizeNamespaceSegment(segment)` — namespace prefix matching with
dynamic-suffix normalization (e.g. `fetcher:<uuid>` matches the
`fetcher` prefix).
- `SUPPORTED_CHANNELS` / `isSupportedChannel(value)` — the recognized
channel set and a guard for validating subscription requests.

Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Deduplicate the client stream transports: the protocol transport now
shares the SSE decoder and `IterableReadableStream` helpers with the
legacy transport instead of carrying its own copies. Removes the
redundant `transport/decoder.ts` and `transport/stream.ts` shims (and a
dead `StreamPart` re-export), importing the shared utilities from
`utils/sse.ts` directly. No public API or behavior change.

fix(langgraph): forward named custom stream channels consistently

Forward remote `StreamChannel` emissions as `custom:<name>` protocol
events and normalize them back to custom-channel payloads in the API
session. This aligns JavaScript stream-channel forwarding with the
protocol subscription shape used by remote clients, so `custom:<name>`
subscriptions receive extension channel data consistently.

fix(sdk): coalesce duplicate thread read requests

Coalesce concurrent identical `threads.getState()` and
`threads.getHistory()` reads within the SDK client so transient remounts
do not issue duplicate hydrate requests. Request identity includes the
prepared URL, body, method, and headers, and coalescing is skipped for
caller-provided abort signals, raw response reads, and `onRequest` hooks
to preserve auth and cancellation isolation.

fix(sdk): reconcile subagents and subgraphs on thread reconnect

Seed deep-agent subagent cards from checkpoint messages and subgraph
hosts from a single bounded `getHistory` read during `hydrate()`, so
parallel fan-out discovery reappears immediately on refresh instead of
waiting for SSE replay. Subagent execution namespaces are promoted
through the existing guarded discovery state machine (bulk at hydrate,
lazily per opened card via the selector layer). The getHistory cost is

fix(core): keep stream chunks as three-element tuples

    Emit lightweight checkpoint envelopes as separate
`[namespace, "checkpoints", envelope]` chunks before paired `values`
chunks.
    Public `stream()` always yields `[namespace, mode, payload]`; the v3
    protocol path surfaces envelopes via `convertToProtocolEvent`.

fix(sdk): surface resumed run failures on stream.error

Route `respond()` and `respondAll()` through a coordinator dispatch path
that
writes the reactive `rootStore.error` slot when a resumed run reaches a
failed
terminal or when `input.respond` dispatch fails, matching submit()
behavior so
framework consumers (e.g. API-key retry UIs) observe resume failures via
    `stream.error` instead of only `isLoading` transitions.

feat(openrouter): surface reasoning content as v1 standard content
blocks</p>
<p><code>convertOpenRouterResponseToBaseMessage</code> and
<code>convertOpenRouterDeltaToBaseMessageChunk</code> now copy
OpenRouter's
<code>reasoning</code> (flat string) and <code>reasoning_details</code>
(structured array) fields
onto <code>additional_kwargs.reasoning_content</code> /
<code>additional_kwargs.reasoning_details</code>.
A new <code>ChatOpenRouterTranslator</code> is registered in
<code>@langchain/core</code> under
the <code>&quot;openrouter&quot;</code> provider key so
<code>AIMessage.contentBlocks</code> emits standard
<code>{type: &quot;reasoning&quot;}</code> blocks alongside text and
tool calls.</p>
<p>Previously, reasoning text returned by reasoning-capable models
routed
through OpenRouter (DeepSeek R1, Minimax M2, Claude extended thinking,
o-series, etc.) was silently dropped: only the
<code>reasoning_tokens</code> count
was preserved via <code>usage_metadata</code>. Consumers using standard
content blocks
(including the frontend agent UI patterns shown in the docs) could not
display the model's chain of thought.</p>

fix(langchain/createAgent): throw on terminal
<code>providerStrategy</code> parse failure instead of silently
resolving with <code>structuredResponse: undefined</code></p>
<p>When <code>createAgent</code> was configured with
<code>responseFormat</code> resolving to a <code>providerStrategy</code>
(either passed explicitly or auto-promoted from a bare Zod / JSON schema
for models whose profile reports <code>structuredOutput: true</code>),
and the model produced a terminal response (no <code>tool_calls</code>)
whose text could not be JSON-parsed or did not satisfy the schema, the
agent silently exited with no <code>structuredResponse</code>, surfacing
later as <code>TypeError: Cannot read properties of undefined</code>.
The agent now throws a <code>StructuredOutputParsingError</code> in that
case while still allowing the agent loop to continue when tool calls are
present. Closes <a

fix(openai): guard bare <code>JSON.parse</code> in Responses API
converter against trailing non-whitespace characters</p>
<p><code>convertResponsesDeltaToChatGenerationChunk</code> previously
called <code>JSON.parse(msg.text)</code> directly when
<code>response.text.format.type === &quot;json_schema&quot;</code>. Some
models (observed with <code>gpt-5-mini</code> on <code>service_tier:
&quot;auto&quot;</code>) intermittently emit trailing non-whitespace
characters (extra tokens, control characters) after a valid JSON object,
causing a <code>SyntaxError</code> that propagates as an unhandled
exception and kills the entire streaming response mid-flight. The parse
is now wrapped in a <code>try</code>/<code>catch</code>: on failure,
<code>additional_kwargs.parsed</code> is left undefined, the stream
completes normally, and the existing <code>withStructuredOutput</code>
pipeline handles the typed failure — <code>includeRaw: true</code>
returns <code>{ raw, parsed: null }</code> via its
<code>withFallbacks</code> wrapper, <code>includeRaw: false</code>
throws a typed <code>OutputParserException</code> that the caller can
catch and retry. Closes <a

github-actions[bot] 34b7f6cfc5 chore: version packages (#2485) 
This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.


# Releases
## @langchain/langgraph-sdk@1.9.15

### Patch Changes

- [#2484](https://github.com/langchain-ai/langgraphjs/pull/2484)
[`9861f42`](https://github.com/langchain-ai/langgraphjs/commit/9861f42cc4fa23d9e80ae45a76d511d7618cda07)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(sdk): claim in-flight slot before root pump wait for enqueue

Move `#runAbort` and `isLoading` setup ahead of `waitForRootPumpReady()`
so
`multitaskStrategy: "enqueue"` submits in the same tick land in
`queueStore`
    instead of bypassing the client queue.

github-actions[bot] 540656afd0 chore: version packages (#2483) 
This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.


# Releases
## @langchain/langgraph-sdk@1.9.14

### Patch Changes

- [#2482](https://github.com/langchain-ai/langgraphjs/pull/2482)
[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(sdk): keep subgraph status complete when values arrives late

    `SubgraphDiscovery` no longer downgrades a terminal subgraph back to
`running` when a host-namespace `values` snapshot is observed after its
`completed` or `failed` lifecycle event. The content pump and lifecycle
watcher are independent streams, so this reordering could strand nodes
as
    perpetually running in `useStream` subgraph UIs.

<p>Vite 8+ can handle React Refresh Transform by Oxc and doesn't need

fix(sdk): normalize HITL edit decisions for Python servers

`StreamController.respond()` now mirrors camelCase and snake_case on
edit
decisions (`editedAction` / `edited_action`) so JS clients can resume
    human-in-the-loop interrupts against Python LangGraph servers.

fix(sdk): route headless tool resumes through respond on v1 stream

`useStream` was calling `submit(null, { command })` for headless-tool
resumes,
    which dispatches `run.start` without delivering the tool result. Add
`applyHeadlessToolResumeCommand` to route payloads through `respond` /
`respondAll`, and tighten headless-tool browser tests to assert
end-to-end
    resume and graph completion.

Thanks [@dependabot](https://github.com/apps/dependabot)! - chore(deps):
bump uuid to 14.0.0 and keep checkpoint ID ordering stable

Bump `uuid` from 10.x/13.x to 14.0.0 across packages. Starting with uuid
11, `v6({ clockseq })` no longer advances the sub-millisecond time
counter when an explicit `clockseq` is passed, so checkpoint IDs created
within the same millisecond were ordered only by `clockseq`. Since
checkpoint IDs are sorted lexicographically, this broke ordering — most
visibly for the negative `clockseq` used by the first ("input")
checkpoint, which sorted as the newest.

`uuid6()` now maintains its own monotonic `(msecs, nsecs)` clock
(mirroring uuid 10's internal v1 behavior) so the time component is
always strictly increasing and checkpoint ordering no longer depends on
the `clockseq` value. `emptyCheckpoint()` also uses a non-negative
`clockseq`.

Decouple `ContextType` generic from `configurable` in `PregelOptions` so
that providing a custom context type no longer incorrectly narrows the
configurable parameter.

bump uuid to 14.0.0 and keep checkpoint ID ordering stable

Bump `uuid` from 10.x/13.x to 14.0.0 across packages. Starting with uuid
11, `v6({ clockseq })` no longer advances the sub-millisecond time
counter when an explicit `clockseq` is passed, so checkpoint IDs created
within the same millisecond were ordered only by `clockseq`. Since
checkpoint IDs are sorted lexicographically, this broke ordering — most
visibly for the negative `clockseq` used by the first ("input")
checkpoint, which sorted as the newest.

`uuid6()` now maintains its own monotonic `(msecs, nsecs)` clock
(mirroring uuid 10's internal v1 behavior) so the time component is
always strictly increasing and checkpoint ordering no longer depends on
the `clockseq` value. `emptyCheckpoint()` also uses a non-negative
`clockseq`.

fix(langgraph-checkpoint): block prototype pollution in MemorySaver via
reserved storage keys

    `MemorySaver` previously embedded `thread_id`, `checkpoint_ns`,
`checkpoint_id`, and `task_id` directly into property accesses on the
nested plain objects `this.storage` and `this.writes`. A caller able to
shape any of those fields (every quickstart, tutorial, and test fixture
    uses `MemorySaver` by default) could pass `"__proto__"`,
    `"constructor"`, or `"prototype"` and have the subsequent assignment
    mutate `Object.prototype`. From that point every plain object in the
    process inherits the injected property, breaking `for...in` loops,
truthy short-circuits, and downstream serializers across unrelated code
    paths. CWE-1321.

Adds an `assertSafeStorageKey` chokepoint applied at every public entry
that touches `storage` or `writes` (`put`, `putWrites`, `deleteThread`,
    `getTuple`, `list`). The guard rejects non-string values, the empty
string (unless explicitly opted-in for `checkpoint_ns`), and the three
    prototype-pollution keys. Behaviour for valid string identifiers is
    unchanged.

fix(checkpoint-redis): block Redis KEYS / SCAN pattern injection via
top-level identifiers

`RedisSaver` and `ShallowRedisSaver` previously embedded `thread_id`,
`checkpoint_ns`, `checkpoint_id`, and `task_id` directly into Redis keys
and `client.keys(pattern)` calls with no validation. A caller able to
    shape any of those fields (multi-tenant SDK deployments where the
`RunnableConfig` originates from request input, or webhook payloads that
flow into a persisted thread) could promote a string identifier into a
    glob pattern (`*`, `?`, `[...]`) or escape character (`\`).

    The most severe sink is `deleteThread`: a `threadId` of `*` issues
`client.keys("checkpoint:*:*")` followed by `client.del(...)`, deleting
    every checkpoint in the database across every tenant. `getTuple`,
    `list`, and `loadPendingWrites` are exposed to the same pattern via
the fallback paths that bypass the existing `escapeRediSearchTagValue`
    defense.

    Adds a single `assertSafeKeyComponent` helper exported from
    `./utils.js` and applies it at every key-building site. The guard
    asserts the value is a non-empty string (the empty `checkpoint_ns`
    default is opt-in via `{ allowEmpty: true }`) and rejects the Redis
pattern meta-characters `* ? [ ] \`. The `:` delimiter is intentionally
    permitted because LangGraph emits it as a legitimate part of
    `checkpoint_ns` for subgraphs / nested graphs, where it only ever
appears as a literal in the key. Behavior for valid string identifiers
    is unchanged.

protocol-v2: fold forkFrom client-side and honor per-run
multitaskStrategy

    The SDK now folds the ergonomic `forkFrom` option into
`config.configurable.checkpoint_id` before sending `run.start`, so the
agent server only ever accepts the single, legacy-compliant fork field
(`forkFrom` no longer hits the wire). The protocol-v2 reference servers
    drop their top-level `forkFrom` normalization accordingly.

The protocol-v2 servers now honor the caller's `multitaskStrategy` per
run (one of `reject` \| `rollback` \| `interrupt` \| `enqueue`) instead
of
hardcoding it, falling back to `enqueue` when omitted or unrecognized.

protocol-v2: add `respondAll()` and run config/metadata on interrupt
resume

The stream controller (and the React/Angular/Svelte/Vue wrappers) gain a
`respondAll(responsesById, options)` method to resume several interrupts
pending at the same checkpoint in a single command — required for runs
that
pause on multiple interrupts at once (e.g. parallel tool-authorization
      prompts), which sequential `respond()` calls cannot handle.

`respond()` now takes an options object (`{ interruptId?, namespace?,
config?, metadata? }`) so a resumed run can carry the same run-level
config
(model, user context, …) and metadata (trigger source, test flags, …) a
fresh `submit()` would. The protocol-v2 reference servers read the new
`responses` batch and `config` / `metadata` fields leniently and fold
them
      onto the run that services the `input.respond` command.

refactor(sdk): drop StreamSubmitOptions.command and simplify forkFrom

StreamController; HITL resume is respond() only. Accept forkFrom as a

protocol-v2: fold forkFrom client-side and honor per-run
multitaskStrategy

    The SDK now folds the ergonomic `forkFrom` option into
`config.configurable.checkpoint_id` before sending `run.start`, so the
agent server only ever accepts the single, legacy-compliant fork field
(`forkFrom` no longer hits the wire). The protocol-v2 reference servers
    drop their top-level `forkFrom` normalization accordingly.

The protocol-v2 servers now honor the caller's `multitaskStrategy` per
run (one of `reject` \| `rollback` \| `interrupt` \| `enqueue`) instead
of
hardcoding it, falling back to `enqueue` when omitted or unrecognized.

protocol-v2: add `respondAll()` and run config/metadata on interrupt
resume

The stream controller (and the React/Angular/Svelte/Vue wrappers) gain a
`respondAll(responsesById, options)` method to resume several interrupts
pending at the same checkpoint in a single command — required for runs
that
pause on multiple interrupts at once (e.g. parallel tool-authorization
      prompts), which sequential `respond()` calls cannot handle.

`respond()` now takes an options object (`{ interruptId?, namespace?,
config?, metadata? }`) so a resumed run can carry the same run-level
config
(model, user context, …) and metadata (trigger source, test flags, …) a
fresh `submit()` would. The protocol-v2 reference servers read the new
`responses` batch and `config` / `metadata` fields leniently and fold
them
      onto the run that services the `input.respond` command.

fix(sdk): preserve apiUrl path prefix in stream transport URLs

Use BaseClient-style URL concatenation in `toAbsoluteUrl` so SSE and
WebSocket
subscriptions work when the SDK is pointed at a proxied apiUrl with a
path
    prefix (e.g. `/api/chat-langchain`).

fix(sdk): cancel runs on stop by default and add disconnect()

`stream.stop()` now calls `client.runs.cancel` for the active run before
disconnecting the client (default `{ cancel: true }`). Join/rejoin UIs
can call `stream.disconnect()` or `stop({ cancel: false })` to leave the

fix(sdk): unwrap Command tool outputs and hide scoped task tools

    Filter wrapper `task` dispatch events from subagent-scoped tool-call
    projections and parse embedded ToolMessage results from LangGraph
    `Command` payloads on `tool-finished`.

- [#2434](https://github.com/langchain-ai/langgraphjs/pull/2434)

Thanks [@hntrl](https://github.com/hntrl)! - fix(react): avoid eager
stream getter evaluation during object spread

Mark optional `useStream` accessors as non-enumerable so object
spread/rest destructuring does not accidentally read guarded fields like
`history` or opt into additional stream modes.

github-actions[bot] 4a7d9a7c5d chore: version packages (#2416) 
This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.


# Releases
## @langchain/langgraph@1.3.2

### Patch Changes

- [#2415](https://github.com/langchain-ai/langgraphjs/pull/2415)
[`9d3c9dd`](https://github.com/langchain-ai/langgraphjs/commit/9d3c9dd3182059f9eca9fd9b14d8f7466b4338c4)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Move `@langchain/core` from a runtime dependency back to a required peer
dependency so installing the SDK alone no longer pulls in
`@langchain/core` (and `js-tiktoken`, etc.). Consumers that use
streaming or message coercion must install `@langchain/core` explicitly
or via `@langchain/langgraph`.

- Updated dependencies

# Releases
## @langchain/langgraph-checkpoint-mongodb@1.3.1

### Patch Changes

- [#2397](https://github.com/langchain-ai/langgraphjs/pull/2397)
[`284226c`](https://github.com/langchain-ai/langgraphjs/commit/284226c7ca164b3c81fe2d9e32b10f1fc6b99a3c)
Thanks [@hntrl](https://github.com/hntrl)! - fix(checkpoint-mongodb):
validate configurable checkpoint identifiers before queries

Add runtime validation for `thread_id`, `checkpoint_ns`, and
`checkpoint_id` in
`MongoDBSaver` methods that read and write checkpoints. This prevents
object-based
operator payloads from being passed into MongoDB query filters and
ensures invalid
    configurable values fail fast with explicit errors.

## @langchain/langgraph-api@1.2.2

### Patch Changes

- [#2396](https://github.com/langchain-ai/langgraphjs/pull/2396)
[`9b20df0`](https://github.com/langchain-ai/langgraphjs/commit/9b20df081a82b79efca3dfd2c128243889b11eb8)

[`4fd1e9f`](https://github.com/langchain-ai/langgraphjs/commit/4fd1e9f5720361a86a386a286ad8fcc824643280)
Thanks [@hntrl](https://github.com/hntrl)! - fix(langgraph): prefer
configurable assistant and graph IDs for runtime server info

Update runtime `serverInfo` construction to read `assistant_id` and
`graph_id` from
`config.configurable` first, with fallback to `config.metadata` for
compatibility.
Also expands `execution_info` tests to cover configurable sourcing,
precedence,
    and metadata fallback behavior.

- [#2387](https://github.com/langchain-ai/langgraphjs/pull/2387)
[`44746b1`](https://github.com/langchain-ai/langgraphjs/commit/44746b1a3b5b49737542b120b9e45d6f94181113)
Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - Coalesce
`RootMessageProjection` store writes through a single `setTimeout(0)`
flush so long `messages`-channel replays (on refresh, mid-run join, or
rapid subagent streaming) no longer drain as a per-event microtask chain
that trips React's `Maximum update depth exceeded` guard. Replaces the
previous `MessageChannel`-based batching, which deferred initial-submit
events past the first render and left the UI looking frozen until
refresh.

[`4cc6491`](https://github.com/langchain-ai/langgraphjs/commit/4cc6491844f21ed0fc737eaef8498133daa877f7)
Thanks [@ahmed-z0](https://github.com/ahmed-z0)! - Fix subagent message
routing to prefer the stream event namespace over checkpoint metadata
when filtering subagent messages.

- [#2384](https://github.com/langchain-ai/langgraphjs/pull/2384)
[`ae8af2d`](https://github.com/langchain-ai/langgraphjs/commit/ae8af2d75aef9a7bbd930d221d1ce03e7fbb90ad)

[`75e651b`](https://github.com/langchain-ai/langgraphjs/commit/75e651b9cff1a1e39ad6513b8a5e9b565b9ad7fe)

Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - Bind
deepagents subagent discovery to the execution namespace via taskInput
so `useMessages(stream, subagent)` resolves the streaming scope instead
of the trigger tool-call namespace.

github-actions[bot] 22c4541b53 chore: version packages (rc) (#2385) 
This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

`main` is currently in **pre mode** so this branch has prereleases
rather than normal releases. If you want to exit prereleases, run
`changeset pre exit` on `main`.

⚠️⚠️⚠️⚠️⚠️⚠️

[`4fd1e9f`](https://github.com/langchain-ai/langgraphjs/commit/4fd1e9f5720361a86a386a286ad8fcc824643280)
Thanks [@hntrl](https://github.com/hntrl)! - fix(langgraph): prefer
configurable assistant and graph IDs for runtime server info

Update runtime `serverInfo` construction to read `assistant_id` and
`graph_id` from
`config.configurable` first, with fallback to `config.metadata` for
compatibility.
Also expands `execution_info` tests to cover configurable sourcing,
precedence,
    and metadata fallback behavior.

- [#2387](https://github.com/langchain-ai/langgraphjs/pull/2387)
[`44746b1`](https://github.com/langchain-ai/langgraphjs/commit/44746b1a3b5b49737542b120b9e45d6f94181113)
Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - Coalesce
`RootMessageProjection` store writes through a single `setTimeout(0)`
flush so long `messages`-channel replays (on refresh, mid-run join, or
rapid subagent streaming) no longer drain as a per-event microtask chain
that trips React's `Maximum update depth exceeded` guard. Replaces the
previous `MessageChannel`-based batching, which deferred initial-submit
events past the first render and left the UI looking frozen until
refresh.

- [#2372](https://github.com/langchain-ai/langgraphjs/pull/2372)
[`4cc6491`](https://github.com/langchain-ai/langgraphjs/commit/4cc6491844f21ed0fc737eaef8498133daa877f7)
Thanks [@ahmed-z0](https://github.com/ahmed-z0)! - Fix subagent message
routing to prefer the stream event namespace over checkpoint metadata
when filtering subagent messages.

- [#2384](https://github.com/langchain-ai/langgraphjs/pull/2384)
[`ae8af2d`](https://github.com/langchain-ai/langgraphjs/commit/ae8af2d75aef9a7bbd930d221d1ce03e7fbb90ad)
Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - batch
RootMessageProjection store writes through a macrotask

- [#2381](https://github.com/langchain-ai/langgraphjs/pull/2381)
[`2ad1aa4`](https://github.com/langchain-ai/langgraphjs/commit/2ad1aa48c6a3f45340b4833e6de555fdc7348d15)
Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - fix(sdk):
forward config + metadata on respondInput for resume submits

- [#2379](https://github.com/langchain-ai/langgraphjs/pull/2379)
[`75e651b`](https://github.com/langchain-ai/langgraphjs/commit/75e651b9cff1a1e39ad6513b8a5e9b565b9ad7fe)
Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - filter
SSE-replayed input.requested events through a hydrated interrupt
allowlist

- [#2390](https://github.com/langchain-ai/langgraphjs/pull/2390)
[`f1d651a`](https://github.com/langchain-ai/langgraphjs/commit/f1d651ae14ca178f4a915ac853ba9b439cd55ba3)
Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - Bind
deepagents subagent discovery to the execution namespace via taskInput
so `useMessages(stream, subagent)` resolves the streaming scope instead
of the trigger tool-call namespace.

# Releases
## @langchain/angular@1.0.0

### Major Changes

- [#2314](https://github.com/langchain-ai/langgraphjs/pull/2314)
[`085a07f`](https://github.com/langchain-ai/langgraphjs/commit/085a07f569b6d7d79728eb7eb6eb3a0c67fcdefb)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the Angular event streaming integration.

Angular applications can now build on the shared event streaming runtime
with
    `useStream`, `injectStream`, `StreamService`, `provideStream`,
`provideStreamDefaults`, `injectProjection`, and selector helpers for
messages,
values, tool calls, custom channels, extensions, media, message
metadata, and
submission queues. The integration supports thread switching, run
submission,
reattachment, interrupts, WebSocket and SSE/custom transports, headless
tools,
    subgraphs, subagents, and typed event projections.

    This release also adds Angular-specific media helpers, including
`injectMediaUrl` and selectors for audio, images, video, and files. The
package
now exports the shared stream, media, transport, headless-tool, and type
    inference types needed to compose strongly typed streaming UIs.

The documentation has been refreshed with guides for dependency
injection,
`injectStream`, selectors, transports, custom transports, interrupts,
submission queues, headless tools, subagents/subgraphs, type safety,
testing,
    and migration from the previous SDK surface.

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the React event streaming integration.

React applications can now use the shared event streaming runtime
through
`useStream`, `useProjection`, `useSuspenseStream`, `StreamProvider`, and
focused selector hooks for messages, values, tool calls, custom
channels,
extensions, media, message metadata, and submission queues. The new
integration
    supports thread-scoped runs, reattachment, interrupts, WebSocket and
SSE/custom transports, headless tools, subgraphs, subagents, typed
stream
    extensions, and strongly typed state/tool-call inference.

This release also adds media helpers for streaming UI experiences,
including
`useMediaURL`, `useAudioPlayer`, and `useVideoPlayer`, plus selectors
for
audio, images, video, and files. Shared transport, media, protocol
event,
message metadata, and discovery types are exported from the package so
React
components can compose richer streaming interfaces without deep imports.

    The package documentation and tests have been expanded around custom
transports, selectors, interrupts, multimodal streaming, suspense,
submission
queues, headless tools, subagents, type safety, and migration from the
previous
    streaming API.

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the Svelte event streaming integration.

Svelte applications can now use the shared event streaming runtime
through
`useStream`, `useProjection`, context helpers, and selector runes for
messages,
values, tool calls, custom channels, extensions, media, message
metadata, and
submission queues. The integration supports thread-scoped runs,
reattachment,
interrupts, WebSocket and SSE/custom transports, headless tools,
subgraphs,
subagents, typed stream extensions, and strongly typed state/tool-call
    inference.

This release also adds Svelte media helpers, including `useMediaURL`,
`useAudioPlayer`, and `useVideoPlayer`, plus selectors for audio,
images,
video, and files. Shared transport, media, protocol event, message
metadata,
and discovery types are exported from the package so Svelte components
can
    compose streaming interfaces without deep imports.

The package now includes focused documentation and tests for context,
custom
    transports, selectors, interrupts, hydration, submission queues,
subscriptions, headless tools, subagents, type safety, and migration
from the
    previous streaming API.

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the Vue event streaming integration.

Vue applications can now use the shared event streaming runtime through
`useStream`, `useProjection`, `provideStream`, `useStreamContext`, and
selector composables for messages, values, tool calls, custom channels,
extensions, media, message metadata, and submission queues. The
integration
    supports thread-scoped runs, reattachment, interrupts, WebSocket and
SSE/custom transports, headless tools, subgraphs, subagents, typed
stream
    extensions, and strongly typed state/tool-call inference.

    This release also adds Vue media helpers, including `useMediaURL`,

images,
video, and files. Shared transport, media, protocol event, message
metadata,
and discovery types are exported from the package so Vue components can
build
    rich streaming UIs without deep imports.

The package documentation and tests now cover API usage, custom
transports,
forking, interrupts, multimodal streaming, selectors, shared streams,
subagents, suspense, submission queues, transports, type safety, and
migration
    from the previous streaming API.

[`085a07f`](https://github.com/langchain-ai/langgraphjs/commit/085a07f569b6d7d79728eb7eb6eb3a0c67fcdefb)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the thread-scoped event streaming protocol used by the new SDK streaming
    clients.

This release adds protocol routes for WebSocket and SSE/HTTP streaming,
including thread-local command handling, filtered subscriptions, event
replay,
state inspection, checkpoint listing/forking, interrupt input, agent
tree
queries, and run start/resume commands. Stream events are normalized
into the
canonical protocol shape with ordered sequence IDs so clients can safely
dedupe, resume subscriptions, and coordinate multiple projections from
the same
    run.

The experimental embed server now supports the same protocol flow, so
embedded
graphs can serve the new SDK transports without standing up a separate
LangGraph API deployment. The server also gains protocol session tests
and
fixture graphs covering deep agents, interrupts, subgraphs, and SDK
transport
    behavior.

### Patch Changes

-   Updated dependencies \[]:
    -   @langchain/langgraph-ui@1.2.0

## @langchain/langgraph@1.3.0

### Minor Changes

- [#2314](https://github.com/langchain-ai/langgraphjs/pull/2314)
[`085a07f`](https://github.com/langchain-ai/langgraphjs/commit/085a07f569b6d7d79728eb7eb6eb3a0c67fcdefb)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the in-process event streaming runtime behind `streamEvents`.

LangGraph now exposes the core primitives for event-based streaming,
including
`StreamChannel`, `StreamMux`, `GraphRunStream`, `SubgraphRunStream`,
native
stream transformers, and protocol event conversion utilities. These APIs
let
graphs emit ordered protocol events, derive additional projections,
expose
custom stream channels, and bridge in-process runs to remote SDK
clients.

The runtime includes built-in transformers for messages, values,
lifecycle
    events, and subgraph discovery. It also adds support for transformer
registration during graph execution, forwarding remote `StreamChannel`
output,
subgraph-aware event routing, event log multiplexing, and
checkpoint-aware
    values streams.

This release also expands test coverage across Pregel streaming, event
    conversion, stream muxing, stream channels, run streams, lifecycle
transformers, subgraph transformers, and type-level streaming behavior.

[`085a07f`](https://github.com/langchain-ai/langgraphjs/commit/085a07f569b6d7d79728eb7eb6eb3a0c67fcdefb)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the framework-agnostic event streaming SDK.

    The SDK now includes a thread-focused streaming client built around
`ThreadStream`, `SubscriptionHandle`, message assembly, media assembly,
typed
stream extensions, and pluggable protocol transports. Applications can
stream
over SSE or WebSocket, provide custom agent-server adapters, subscribe
to
values/messages/tools/custom/lifecycle/checkpoint channels, inspect and
fork
state, respond to interrupts, and replay or dedupe ordered event
streams.

This release also adds the reusable stream runtime used by the React,
Vue,
    Svelte, and Angular packages: `StreamController`, `StreamStore`,
`ChannelRegistry`, projection factories, subagent/subgraph discovery,
submission queue coordination, message metadata tracking, root message
projection, media projections, and helper types for agent/deep-agent
state and
    tool-call inference.

The client package has been reorganized into focused modules for
assistants,
threads, runs, store, protocol streaming, transports, media, messages,
and UI
helpers. New SDK documentation covers configuration, assistants,
threads, runs,
store, streaming, transports, extensions, interrupts, messages, media,
    subagents, and subgraphs.

[`085a07f`](https://github.com/langchain-ai/langgraphjs/commit/085a07f569b6d7d79728eb7eb6eb3a0c67fcdefb)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Improve `MemorySaver` diagnostics when checkpoint writes are missing a
      `thread_id`.

The in-memory checkpointer now explains why `configurable.thread_id` is
required and includes a concrete `graph.stream(..., { configurable: {
    thread_id } })` example in the error message. This makes the new
thread-oriented event streaming flows easier to debug when an
application
      forgets to provide durable thread configuration.

Hunter Lovell 9102d526c8 fix(langgraph): propagate tracer metadata defaults from configurable (#2315) 
## Summary

This updates Pregel callback manager initialization to pass
`tracerInheritableMetadata` defaults derived from `config.configurable`,
and narrows `ensureLangGraphConfig` metadata mirroring to the
allowlisted LangGraph identifiers used in stream/runtime metadata.

## Changes

### `@langchain/langgraph` (`libs/langgraph-core`)

- Updated Pregel callback manager setup to configure core callbacks with
`tracerInheritableMetadata` based on configurable primitive values,
excluding internal and secret-like keys.
- Hoisted tracing default logic into `_getTracingMetadataDefaults` and
`_excludeAsMetadata` for parity with the Python implementation shape.
- Restricted `ensureLangGraphConfig` configurable-to-metadata
propagation to the identifier allowlist:
  - `thread_id`
  - `checkpoint_id`
  - `checkpoint_ns`
  - `task_id`
  - `run_id`
  - `assistant_id`
  - `graph_id`
- Updated config tests to assert the narrowed metadata propagation
behavior.
