ADK 0.9 introduces durable checkpoints across Agent Graph workflows, allowing teams to pause execution, inspect state, and resume from the last committed step. Human-in-the-loop gates can block downstream nodes until an approver signs off in the control plane.
Highlights
- Checkpoint persistence with configurable retention
- HITL gates wired to IAM roles and treaty policy
- SDK helpers for pause, resume, and approval callbacks
- Compatible with existing AgentApp packaging
ADK 0.9 is available now via the standard SDK channels. Upgrade guides and migration notes are published alongside the release.
