[dependabot]

Bumps @langchain/langgraph from 1.1.4 to 1.2.0.

Release notes

Sourced from @​langchain/langgraph's releases.

@​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.

@​langchain/langgraph@​1.2.0

Minor Changes

• #2002 fce9d38 Thanks @​hntrl! - feat(langgraph): add Overwrite class for bypassing channel reducers

  Adds an Overwrite class and OverwriteValue type that allow nodes to bypass reducers in BinaryOperatorAggregate channels, writing values directly instead of passing them through the reducer function. This is useful when a node needs to replace accumulated state rather than append to it.

  • New Overwrite class exported from @langchain/langgraph
  • BinaryOperatorAggregate channel detects OverwriteValue and sets the value directly
  • Annotation, StateSchema, and zod schema type mappings updated to include OverwriteValue in update types

Patch Changes

• #1992 937f780 Thanks @​christian-bromann! - fix(core): don't trace channel read/writes
