Google's ADK 2.11 adds graceful cancellation and human approval for workflow tool calls

Release 2.11.0 of Google's Agent Development Kit for Python lets you pass an abort signal to runners, workflows and nodes to stop a run gracefully, and its streaming endpoint now cancels the run when the client disconnects. Tool nodes in workflows now pause for user approval the way an LLM agent does, instead of passing an error downstream. The release also adds a tool for consulting another model mid-task and a built-in SQLite memory service.

What it means Being able to stop a run cleanly and requiring approval before a tool call are two controls production agent workflows usually have to build themselves.
