AutoGen 0.4 rebuilds Microsoft’s agent framework around events and observability
Microsoft released a ground-up AutoGen redesign with asynchronous messaging, typed interfaces, OpenTelemetry tracing, resumable state and a layered Core/AgentChat/Extensions architecture. The release also rebuilt AutoGen Studio and added controls for pausing, inspecting and steering multi-agent runs.
Why it matters: The hard part of production agents is often lifecycle control rather than prompting. AutoGen 0.4 made tracing, intervention and distributed execution first-class framework concerns.
