Updates @langchain/core from 0.3.80 to 1.1.44

Release notes

Sourced from @​langchain/core's releases.

@​langchain/core@​1.1.41

Patch Changes

@​langchain/core@​1.1.40

Patch Changes

  • #10694 d3e0809 Thanks @​hntrl! - refactor(core): decouple tracer-only metadata defaults from runnable metadata
    • Add tracer-scoped inheritable metadata/tag options in callback manager while keeping backward-compatible aliases.
    • Move configurable-to-tracing metadata derivation into a tracer-only path and keep ensureConfig metadata mirroring limited to model.
    • Update LangChainTracer default metadata/tag handling and add regression tests for stream events metadata behavior.

@​langchain/core@​1.1.39

Patch Changes

@​langchain/core@​1.1.38

Patch Changes

@​langchain/core@​1.1.37

Patch Changes

  • #10511 6933769 Thanks @​hntrl! - cache Zod-to-JSON-Schema conversions in toJsonSchema()

  • #10541 50d5f32 Thanks @​jacoblee93! - revert: Revert "feat(core): Add all chat model/llm invocation params to metadata"

  • #10509 5552999 Thanks @​hntrl! - feat(openai): add support for phase parameter on Responses API messages

    • Extract phase from message output items and surface it on text content blocks
    • Support phase in streaming via response.output_item.added events
    • Round-trip phase through both raw provider and standard content paths
    • Move phase into extras dict in the core standard content translator

  • #10528 8331833 Thanks @​christian-bromann! - fix(core): normalize single-block content in mergeContent

@​langchain/core@​1.1.36

Patch Changes

  • #10512 bbbfea1 Thanks @​hntrl! - fix(core): fix streaming chunk merge for providers without index on tool call deltas

    _mergeLists now falls back to id-based matching when items don't have an index field. Previously, providers routing through the OpenAI-compatible API without index on streaming tool call deltas (e.g. Anthropic models via ChatOpenAI) would accumulate hundreds of individual raw deltas in tool_call_chunks and additional_kwargs.tool_calls instead of merging them into a single entry per tool call. In a real trace with 3 concurrent subagents, this caused a single AI message to balloon from ~4KB to 146KB -- with 826 uncollapsed streaming fragments carrying a few bytes each.

    Also fixes SystemMessage.concat() which used ...this to spread all instance properties (including lc_kwargs) into the new constructor, causing each chained concat() call to nest one level deeper. After 7 middleware concat() calls (typical in deepagents), a 7KB system prompt would serialize to 81KB due to content being duplicated at every nesting level.

Updates @langchain/langgraph from 0.2.20 to 1.2.9

Release notes

Sourced from @​langchain/langgraph's releases.

Patch Changes

@​langchain/langgraph@​1.2.8

Patch Changes

@​langchain/langgraph@​1.2.7

Patch Changes

@​langchain/langgraph@​1.2.6

Patch Changes

  • #2241 6ee23e8 Thanks @​pawel-twardziak! - feat: add browser support for interrupt, writer, and other Node-only exports

    Export interrupt, writer, pushMessage, getStore, getWriter, getConfig, getPreviousState, getCurrentTaskInput from web.ts and add a "browser" condition to the "." package export so browser bundlers resolve to web.js instead of pulling in node:async_hooks.

  • #2245 77af976 Thanks @​hntrl! - revert abort signal change that was causing problematic errors

  • #2242 bdcf290 Thanks @​hntrl! - clean up resolved checkpointer promises to reduce memory retention

  • Updated dependencies [88726df, 7dfcbff]:

    • @​langchain/langgraph-sdk@​1.8.1

@​langchain/langgraph@​1.2.5

Patch Changes

  • #2213 a09932a Thanks @​hntrl! - fix(core): prevent AbortSignal listener leak in stream() and streamEvents()

    Pregel.stream() and streamEvents() called combineAbortSignals() but discarded the dispose function, leaking one abort listener on the caller's signal per invocation. Over many invocations this caused unbounded memory growth as each leaked listener retained references to its associated graph execution state.

    • Use AbortSignal.any() on Node 20+ which handles listener lifecycle automatically via GC
    • Fall back to manual listener management on Node 18, with proper dispose() called when the stream completes or is cancelled

  • #2210 4d2e948 Thanks @​jackjin1997! - Fix AnyValue.update() returning false instead of true when values are received, aligning with all other channel implementations.

  • Updated dependencies [414a7ad]:

    • @​langchain/langgraph-sdk@​1.8.0

@​langchain/openai@​1.3.1

Patch Changes

  • #10481 478652c Thanks @​hnustwjj! - fix(openai): detect DeepSeek context overflow errors as ContextOverflowError

    DeepSeek returns maximum context length in 400 error messages when the context limit is exceeded. These are now recognized by wrapOpenAIClientError, so downstream code (e.g. summarization middleware fallback) can handle them correctly.

  • #10507 52e501b Thanks @​App-arently! - fix(openai): guard JSON.parse in streaming json_schema when text is empty
