- Execution cancellation: Pass an abortsignal to Runner, Workflow, and nodes to stop a run gracefully; /runsse now cancels the run when the client disconnects. See the unit guide for more details.…
- Tool confirmation in workflows: Tool nodes now pause for user approval via RequestInput, the same way an LlmAgent does, instead of passing an error downstream. (ce132b9)
- ModelConsultTool: Let an agent consult another model mid-task, capped by per-turn and per-session budgets. See the unit guide for more details. (84cc99a)
- SQLite memory service: Keep agent memory in a local SQLite database, selected with a sqlite:// memory service URI. (9625b06)
- MCP SDK 2.x: Connect to MCP servers over the modern protocol through a new opt-in path. (e738c26)
- Dev UI runtime config is served by the server: The web server now serves /dev-ui/assets/config/runtime-config.json per request and no longer writes runtime-config.json into the installed package.…

What changed: recent Agent Development Kit (ADK) releases
18 stable releases in the last 90 days · Full changelog
- Skills: Control resource usage and tool persistence dynamically using new ephemeral lifecycles and active skill limits (experimental; enable with ADKENABLESKILLLIFECYCLE=1). (43b73e4)
- Database Integrations: Perform high-performance vector and hybrid searches seamlessly within your agent flows with the new MongoDB toolset. (0961ced)
- Evaluation: Optimize agent execution costs and latency with new evaluation metrics for tracking duration, token consumption, and model call counts. (2d428ea)
- Model Support: Integrate OpenAI reasoning models more effectively with automated request parameter adaptation and precise reasoning token reporting. (52a2f0f)
- BigQuery protected write mode now runs a non-SELECT statement only when the dry run places it in the session's anonymous dataset, so multi-statement scripts, CALL, EXPORT DATA and other statements…
- BigQuery protected mode keeps its BigQuery session in process memory instead of session state, so its temporary tables do not survive a restart or carry over to another replica. (094012b)
- Telemetry: OpenTelemetry event names are now preserved on platforms outside of Agent Engine, ensuring more accurate and consistent tracking. (9110770)
- telemetry: only drop the OTel event name on Agent Engine (9110770)
- Claude Integration: Access the step-by-step reasoning process of Claude models by ensuring visible thoughts are requested during adaptive thinking tasks. (ba0d542)
- request visible thoughts for Claude adaptive thinking (ba0d542)
- Models: Safeguard agent uptime by automatically failing over to backup models when the primary model encounters errors. (c300b8d)
- Integrations: Build rich voice and telephony agents using the newly added LiveKit runner. (f277d91)
- Workflows: Simplify graph workflow management by authoring and loading ADK 2.0 graphs directly from declarative YAML configurations. (2a9461b)
- MCP: Work with MCP SDK 2.x servers as well as 1.x. Installs continue to resolve 1.x by default; install 2.x deliberately to opt in. (856acf2)
- Workflow node resumption: A node that failed now runs again when the workflow resumes, where before it replayed as though it had completed. Make node bodies idempotent: a node that performs an…
- GCS tool local paths: The GCS tools now read and write local files only inside the directory named by localfileroot, and refuse local file access entirely when that setting is absent. Paths may be…
- a2a: Port event action allowlist, agent card description source and resume flattening to v1 (#6801) (1f898a6)
- artifacts: Port app-scoped file artifact storage and layout-derived payload paths to v1 (#6795) (0ae2bff)
- artifacts: Port artifact reference scoping and path-segment validation to v1 (#6794) (efc5bb8)
- cli: check the Host header on every local API server request (v1) (#6789) (15bf230)
- cli: Port deploy ignore-file handling to v1 (#6793) (8467bf0)
- close the residual gaps from the v1 backport review (#6890) (218061e)
