Release notes

Sourced from @​langchain/langgraph's releases.

@​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/langgraph@​1.2.4

Patch Changes

• fe4dd5b Thanks @​christian-bromann! - fix(sdk): fetch subagent history

• Updated dependencies [fe4dd5b, fe4dd5b, fe4dd5b]:

  • @​langchain/langgraph-sdk@​1.7.5

@​langchain/langgraph@​1.2.3

Patch Changes

• #2176 ad48dee Thanks @​pawel-twardziak! - fix(state): merge jsonSchemaExtra in getInputJsonSchema()

• Updated dependencies [8fec72a, a9ff2ef, a24bb55, b80076c, b6cfe55]:

  • @​langchain/langgraph-sdk@​1.7.3
  • @​langchain/langgraph-checkpoint@​1.0.1

@​langchain/langgraph@​1.2.1

Patch Changes

• #2024 b1272bd Thanks @​hntrl! - fix: add explicit : symbol type annotations 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 COMMAND_SYMBOL (used on CommandInstance class)
  • Added : symbol to REDUCED_VALUE_SYMBOL (exported, used on ReducedValue class)
  • Added : symbol to UNTRACKED_VALUE_SYMBOL (exported, used on UntrackedValue class)
  • Fixed TypeScript indexing error by using Record<symbol, unknown> type assertion in ReducedValue.isInstance()

@​langchain/langgraph-checkpoint-mongodb@​1.2.0

Minor Changes

• #1991 38db67f Thanks @​vanb! - Add optional enableTimestamps parameter to MongoDBSaver that sets an upserted_at date via MongoDB's $currentDate operator on every upsert. Useful for MongoDB TTL indexes, auditing, or debugging.
