- Issues
- help for langchain ShellToolMiddleware in langchain/agents/middleware/shell_tool.py
- invoke(version="v2") returns list[StreamPart] instead of GraphOutput when stream_mode != "values" — polymorphic return type undocumented
- InMemoryStore search filters treat dotted keys as literal top-level keys instead of nested paths
- langgraph-runtime-inmem: Runs.Stream.join drops subgraph events when stream_mode is supplied (joinStream regression)
- [BUG] Interrupt() in a loop will cause extra resumes
- fix(langgraph): add missing stacklevel to warnings.warn() calls
- [Partnership] Scoped integration collaboration
- Proposal: Agent Threat Rules detection integration for LangGraph
- fix(langgraph): apply Command(resume=…) when paired with explicit non-head checkpoint
- LangGraph checkpoint serialization produces 85% storage bloat and 37.8% token overhead with no opt-out path - reproducible with drop-in fix
