Release notes

Sourced from @​langchain/core's releases.

@​langchain/core@​1.1.31

Patch Changes

• #10271 7373b4c Thanks @​jacoblee93! - feat(core): Use uuid7 instead of v4 for generating run ids

• #10262 b0175a5 Thanks @​maahir30! - fix: Move fakeModel from utils/testing to testing namespace move to updated namespace

• #10185 414f6ed Thanks @​maahir30! - feat: add custom Vitest matchers for LangChain message and tool call assertions

  Adds a new @langchain/core/testing/matchers export containing custom Vitest matchers (toBeHumanMessage, toBeAIMessage, toBeSystemMessage, toBeToolMessage, toHaveToolCalls, toHaveToolCallCount, toContainToolCall, toHaveToolMessages, toHaveBeenInterrupted, toHaveStructuredResponse) that external users can register via expect.extend(langchainMatchers) in their Vitest setup files. Re-exported from langchain for convenience.

@​langchain/core@​1.1.30

Patch Changes

• #10243 96c630d Thanks @​hntrl! - fix: add explicit : symbol type annotations to Symbol.for() declarations for cross-version compatibility

  TypeScript infers unique symbol type when Symbol.for() is used without an explicit type annotation, causing type incompatibility when multiple versions of the same package are present in a dependency tree. By adding explicit : symbol annotations, all declarations now use the general symbol type, making them compatible across versions while maintaining identical runtime behavior.

  Changes:

  • Added : symbol to MESSAGE_SYMBOL in messages/base.ts
  • Added : symbol to MIDDLEWARE_BRAND in agents/middleware/types.ts (also changed from Symbol() to Symbol.for() for cross-realm compatibility)

• #10256 a8b9ccc Thanks @​colifran! - fix(core): standard schema type guards don't support callable schemas

• #10204 a1f22bb Thanks @​colifran! - feat(core): implement standard schema support for structured output

@​langchain/core@​1.1.29

Patch Changes

• #10106 9f30267 Thanks @​hntrl! - Add package version metadata to runnable traces. Each package now stamps its version in this.metadata.versions at construction time, making version info available in LangSmith trace metadata.

• #10154 403a99f Thanks @​kanweiwei! - fix(core): add usage_metadata to AIMessage lc_aliases

• #10169 3b1fd54 Thanks @​hntrl! - fix(core, langchain): bump uuid dependency from ^10.0.0 to ^11.0.0 to fix Metro bundler error

  The uuid v10 package has ambiguous exports in its package.json which causes Metro (used by Expo/React Native) to resolve the wrong entry point, resulting in Cannot read properties of undefined (reading 'v1'). The uuid v11 package fixes its exports map to work correctly with Metro's package exports resolution.

• #10044 77bd982 Thanks @​hntrl! - fix(core): remove inherited LangChainTracer handlers when tracingEnabled is false

  When a RunTree explicitly disables tracing via tracingEnabled: false, CallbackManager._configureSync now strips any inherited LangChainTracer handlers so child runs don't produce traces.

@​langchain/core@​1.1.28

Patch Changes

• #10140 10a876c Thanks @​hntrl! - Merge content blocks by string index during streaming.

• #10102 b46d96a Thanks @​colifran! - feat: implement aynchronous generator tool calling for streaming partial tool results
