- Issues
- feat(langgraph): run a cancel handler when an async run is cancelled
- sdk-py: output.with_timeout() cancels the original thread.output
- durability="exit": the checkpoints stream reports the wrong parent_config on a thread that already has a checkpoint
- langgraph-sdk: async thread stream stops delivering events and hangs once a subscriber is max_queue_size events behind
- ValidationNode raises KeyError on an unknown tool name
- langgraph.json with a non-string python_version or node_version crashes the CLI with a raw AttributeError/TypeError
- `astream_events` ignores a subgraph's `output_schema`, so a reducer channel takes the subgraph's input back and the run returns duplicated data without any error
- SQLite store integer filters return adjacent values above 2**53
- get_graph() raises UnboundLocalError on a Pregel with list input_channels
- feat(langgraph): prototype `TranscriptChannel`
