Breaking changes: • The `ProtocolEvent.eventId` field is renamed to `event_id` to match the wire field Full history on Cyber Toolchain: https://cybertoolchain.io/tools/langgraph https://github.com/langchain-ai/langgraph/releases/tag/sdk%3D%3D0.4.1 https://github.com/langchain-ai/langgraph/releases/tag/sdk%3D%3D0.4.1 Mon, 01 Jun 2026 15:23:38 GMT LangGraph SDK 0.4.1 adds interleave_projections for stream decoding and v3 streaming support in RemoteGraph. • Adds `interleave_projections` capability via extracted stream decoders in the Python SDK, enabling finer control over streamed output projection. • Enables v3 streaming protocol support in `RemoteGraph`, allowing remote graphs to leverage the latest streaming features.
