chore: version packages

[github-actions]

This PR was opened by the Changesets release 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@1.11.0

Minor Changes

• #2831 3234c69 Thanks @ramon-langchain! - Expose connection lifecycle callbacks for built-in streaming transports.

  onConnected runs after the initial SSE or WebSocket connection becomes usable and after every successful reconnect. Its payload distinguishes an initial connection from a reconnected connection and includes the reconnect attempt number.

  onReconnect now also receives the scheduled delayMs, allowing applications to display accurate retry state before the next connection attempt. React, Vue, Svelte, and Angular stream hooks forward both callbacks.

Patch Changes

• #2831 3234c69 Thanks @ramon-langchain! - Recover cleanly when a thread's root event stream terminates unexpectedly.

  If the stream fails or closes while a run is active, the controller now records the transport error and clears isLoading rather than leaving the UI in a permanently running state. Once the failed pump settles, a later submission can start a fresh root subscription without recreating the thread stream or replaying the failed command.

• #2809 11a4535 Thanks @hntrl! - fix(sdk): appropriately track persisted seq for stream replay

  Sequences weren't being appropriately attributed when rehydrating the page (e.g. on refresh). This meant we'd lose stream information on useStream on reloads. This has been fixed by adding a lookup step to determine what the most appropriate sequence index is to track in the event stream.:x

• #2762 2fab6fd Thanks @JessYanCoding! - Send checkpoint_id in the runs.stream() request body, so a checkpointId passed to client.runs.stream() forks from the requested checkpoint instead of being silently dropped. Matches runs.create() and runs.wait(), which already send it.

• #2813 4fc118f Thanks @eliornl! - fix(sdk): show interrupts raised after a passive thread rejoin

  After a page refresh mid-run, useStream filtered every interrupt it did not
  already know from the hydrated thread state as replayed history, and waited
  for a checkpoints event to lift that filter. Current runtimes never emit
  that event and the replay buffer trims it on long runs, so interrupts raised
  after the refresh never appeared until the next reload. Unknown interrupts are
  now settled against the server's thread state when the run reaches a terminal
  lifecycle: the ones the server lists as pending are shown, the rest are
  dropped as history.

• #2812 db4bdad Thanks @eliornl! - fix(sdk): recover from a server-side thread stream drop instead of freezing

  The protocol SSE transport now reconnects when the server closes the event
  stream cleanly. The thread stream is open-ended, so a clean close only happens
  when the server's own upstream consumer died or it is restarting; before, the
  client treated it as the end of the thread and the UI froze mid-run with no
  error. A connection that delivered events also resets the reconnect budget, so
  long-lived pages survive repeated deploys. maxReconnectAttempts: 0 keeps the
  old end-on-close behavior.

  Unsolicited server error frames (no command id) and a shared stream that gives
  up reconnecting now reach stream.error: ThreadStream.onError exposes them,
  useStream sets error, clears isLoading, and settles the in-flight
  submit() as failed.

• #2808 55fa26b Thanks @hntrl! - fix(sdk): coalesce locally resolved interrupts

  when resolving interrupts using useStream, there was a case where we prioritized the remote state values (which we lookup in React Strict mode on every page transition) over the local interrupt responses we know we've responded with.

  This has since been fixed to first prioritize the local cache of interrupts, resolved against the remote state values when a run hits a terminal event

@langchain/langgraph-api@1.4.6

Patch Changes

• #2751 0a9611a Thanks @t3s7r! - fix(api): run.start with input on a cancelled thread no longer folds the input into Command(resume). A cancelled run shares the "interrupted" status with a genuine interrupt() pause, but has no pending interrupt to consume the resume value, so the submitted message was silently dropped. The input-vs-resume decision now keys on whether the thread actually has pending interrupts (both in the protocol service and the embed protocol).

Patch Changes

• #2794 83a4b62 Thanks @hntrl! - feat(langgraph): add per-node tracePolicy input/output processors and omitPayload

  Transform the payloads recorded on a node's own trace run while retaining its span and timing. Processors receive raw values and fall back to the original payload if they throw. Graph state, root runs, and child runs remain unchanged when processors do not mutate their arguments.

  Matches Python's callback-level behavior: transforms also affect chain events and message streaming, so omitting outputs can suppress messages returned directly by nodes and omitting inputs can affect message deduplication.
