LangGraph 1.2.10 adds TracePolicy controls on nodes

Full analysis

LangGraph — LangChain's graph-based agent orchestration framework — released version 1.2.10 with a handful of meaningful changes for agent builders. The most notable additions are the ability to expose trace_policy directly on add_node, and a follow-up commit that drops tags from TracePolicy (with a subsequent partial revert of a TracePolicy deletion), giving developers finer-grained control over which node executions get traced and how. The release also adds typed return signatures and native projections for v3 stream_events, which improves type safety when streaming events from running agents.
