langchain-ai/langchainjs (@​langchain/core)

v1.2.2

Compare Source

Patch Changes

• #​9777 3efe79c Thanks @​christian-bromann! - fix(core): properly elevate reasoning tokens

v1.2.1

Compare Source

Patch Changes

• #​10674 f017708 Thanks @​christian-bromann! - fix: classify provider 429s before retrying

• #​11092 7918bbd Thanks @​aolsenjazz! - fix(core): only treat arrays of content blocks as ToolMessage content

  Fix tool outputs that are arrays of plain objects being forwarded as malformed message content. An array is now only treated as message content blocks when every element is an object with a type; otherwise it is JSON-stringified.

v1.2.0

Minor Changes

• #​9651 348c37c Thanks @​christian-bromann! - feat(langchain): allow to set strict tag manually in providerStrategy #​9578

v1.1.48

Patch Changes

• #​10832 1b24369 Thanks @​info-arnav! - fix(core, openrouter): make CJS default re-exports callable

• #​10666 2bb55b0 Thanks @​hnustwjj! - feat(openrouter): surface reasoning content as v1 standard content blocks

  convertOpenRouterResponseToBaseMessage and
  convertOpenRouterDeltaToBaseMessageChunk now copy OpenRouter's
  reasoning (flat string) and reasoning_details (structured array) fields
  onto additional_kwargs.reasoning_content / additional_kwargs.reasoning_details.
  A new ChatOpenRouterTranslator is registered in @langchain/core under
  the "openrouter" provider key so AIMessage.contentBlocks emits standard
  {type: "reasoning"} blocks alongside text and tool calls.

  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 reasoning_tokens count
  was preserved via usage_metadata. Consumers using standard content blocks
  (including the frontend agent UI patterns shown in the docs) could not
  display the model's chain of thought.

• #​10918 3999fab Thanks @​christian-bromann! - fix(openai): stream custom tool calls through Responses API chunks

v1.1.47

Compare Source

Patch Changes

• #​10906 f61b345 Thanks @​hntrl! - feat(core): add uuid v6 utility support

  Add v6 UUID generation support to @langchain/core/utils/uuid by vendoring the upstream uuidjs v6 implementation and its v1ToV6 helper, exporting v6 from the UUID utils index, and adding tests for deterministic generation, buffer/offset behavior, validation/versioning, and ordering.

• #​10872 a640079 Thanks @​hntrl! - chore(deps): remove redundant @​types/uuid declarations

  Remove @types/uuid from package manifests that rely on @langchain/core/utils/uuid or do not require uuid type stubs directly, and refresh the lockfile entries accordingly.

• #​10792 3682268 Thanks @​Genmin! - fix(core): apply v1 message casting after implicit streaming aggregation

• #​10901 f26fc4a Thanks @​christian-bromann! - fix(testing): share fakeModel invocation state across bindTools instances

v1.1.46

Patch Changes

• #​10847 1659e7d Thanks @​hntrl! - chore(core): reduce transitive dependency exposure and tighten release hygiene

  Remove direct runtime dependencies on ansi-styles, camelcase, and decamelize
  by inlining equivalent logic in core internals, and enable npm provenance in the
  release workflow.

• #​10790 ef78bc6 Thanks @​Genmin! - fix(core): keep different content block types separate when merging chunks
