LangGraph 1.2.10 exposes per-node trace_policy and lands typed v3 stream_events with native projections
GitHub (langchain-ai/langgraph)·low signal
LangGraph shipped 1.2.10 on July 28 adding a trace_policy argument to add_node, giving per-node control over what gets traced rather than an all-or-nothing graph-level setting, though the release also reverts the standalone TracePolicy deletion and drops tags from it. It types the v3 stream_events return and adds native projections, which matters for anyone building typed streaming UIs on top of graph execution. The rest is dependency bumps, including setuptools 80.9.0 to 83.0.0.
