[dependabot]

Bumps @langchain/langgraph from 1.2.9 to 1.4.8.

Release notes

Sourced from @​langchain/langgraph's releases.

@​langchain/langgraph@​1.4.8

Patch Changes

• #2604 42ec394 Thanks @​hntrl! - fix(pregel): wait for completed-superstep persistence with sync durability

• Updated dependencies [f326b89, c201256]:

  • @​langchain/langgraph-sdk@​1.9.26

@​langchain/langgraph@​1.4.7

Patch Changes

• #2571 85ba859 Thanks @​christian-bromann! - 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.

@​langchain/langgraph@​1.4.6

Patch Changes

• 03a0d8b Thanks @​christian-bromann! - 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.

• Updated dependencies [0558e47, 091a46f]:

  • @​langchain/langgraph-sdk@​1.9.25
  • @​langchain/langgraph-checkpoint@​1.1.3

@​langchain/langgraph@​1.4.5

Patch Changes

• #2557 b1e856d Thanks @​christian-bromann! - 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,
