LangGraph 1.2.17 Fixes Recursion Defaults and RemoteGraph Namespaces

News AI Agent Infrastructure

  • LangGraph 1.2.17 explicitly applies the default recursion limit when setting that limit.
  • RemoteGraph.stream(subgraphs=True) now retains the namespace provided by its caller.
  • The release removes precautionary upper bounds on third-party dependencies.
  • The dependency updates include a certifi upgrade from 2026.1.4 to 2026.10.19.

Our take

Compared with 1.2.16, this release focuses on recursion-limit and RemoteGraph behavior fixes rather than introducing a graph-building feature. Removing third-party dependency caps may change which versions a resolver selects; the release notes do not name the affected packages or state whether migration work is needed.
