# 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`.

# 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)

- [#2376](https://github.com/langchain-ai/langgraphjs/pull/2376)
[`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.

### Patch Changes

- [#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

[`2ad1aa4`](https://github.com/langchain-ai/langgraphjs/commit/2ad1aa48c6a3f45340b4833e6de555fdc7348d15)

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

[`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.

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.

Nick Hollon 2ad1aa48c6 fix(sdk): subscription plumbing — dedicated SSE streams, run.start ordering, WS pre-register (#2381) 
Three subscription-lifecycle correctness fixes; all share
\`client/stream/index.ts\` and are thematically the same surface.

### 1. \`subscribeDedicated\` + dedicated SSE event stream for narrow
projections

Selector hook consumers (\`useMessages\`, \`useToolCalls\`) scoped to a
subagent namespace would otherwise widen the shared content pump's
\`(channels, namespaces)\` union and pull every channel for every active
namespace onto the wire just to satisfy a single narrow consumer. SSE
transports get a fresh \`openEventStream\`; WS falls back to the shared
command stream (no union-widening cost on WS since all events flow on
one connection).

### 2. \`run.start\` lifecycle ordering

The lifecycle watcher and the values projection both open subscriptions
on \`/threads/{id}/stream/events\`; if either lands before \`run.start\`
commits the thread server-side, the server emits a
\`404: Thread not found\` protocol error and the client waits forever
for terminal events. Reorder so \`run.start\` awaits first, then
watchers attach. Also adds \`config\` + \`metadata\` to \`respondInput\`
signature so resume submits can carry per-run configuration overrides
(the v2 server already forwards both).

### 3. Pre-register subscription under a placeholder id before sending
\`subscription.subscribe\`

The WebSocket server replays buffered events through
\`install_subscription_with_replay\` before returning the success
response that carries the \`subscription_id\` — without
pre-registration,
those replayed events arrive at \`#handleIncoming\` while no matching
subscription is registered and never reach the iterator. UI symptom:
\`useMessages\` renders empty after click-to-expand on WebSocket.

## Release Note

None

### 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.

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.

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

    -   @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.

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.

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.

dependabot[bot] 786fe03646 chore(deps): bump vite from 7.3.2 to 8.0.5 (#2322) 2026-04-20 20:07:04 -07:00
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.
