⚠ BREAKING CHANGES
- langchain-agents: the span this handler emits is renamed from
langchain.agentandlangchain.agent.streamtoinvoke_agent. Queries selecting on the old names will not match. Prompt and completion content is no longer on spans unless the caller passes capture_content=True. gen_ai.system changes value; see below.
