ADK Go 1.0 Arrives!- Google Developers Blog

ADK Go 1.0 introduces OpenTelemetry integration for structured tracing of model calls and tool executions, a Plugin System allowing for cross-cutting concerns like 'Retry and Reflect' for self-correction, Human-in-the-Loop (HITL) confirmation flows for sensitive tools (`RequireConfirmation: true`), and YAML configuration support for defining agents and their hierarchies. The Agent2Agent (A2A) protocol is refined for inter-agent communication.
