 ## [3.0.0](https://github.com/google/adk-python/compare/v2.10.0...v3.0.0) (2026-10-01)
 
 
+### Highlights
+
+This release focuses on improving workflow control and agent capabilities, introducing execution cancellation, human-in-the-loop tool confirmations, a dedicated tool for consulting expert models, and compatibility updates for MCP SDK 2.x.
+
+* **Execution Control**: Prevent wasted compute and resources by cleanly aborting running workflows and nodes when a client disconnects. ([ef5bbcf](https://github.com/google/adk-python/commit/ef5bbcfe51670bd211645a043914c162e7c1cd60))
+* **Workflows**: Build secure human-in-the-loop approval flows by pausing tool nodes for user confirmation before execution. ([ce132b9](https://github.com/google/adk-python/commit/ce132b92d471b8df903524593d863171b000a764))
+* **Tools**: Enhance agent reasoning by delegating complex tasks to advisor models using a dedicated consultation tool with turn and session budgets. ([84cc99a](https://github.com/google/adk-python/commit/84cc99abd53010817a85b51fdcdc5d4f48366769))
+* **Integrations**: Connect your agents to the latest Model Context Protocol ecosystem using an opt-in protocol path for MCP SDK 2.x. ([e738c26](https://github.com/google/adk-python/commit/e738c26fe5abcecffe2fbeba31f8d837086aad8a))
+
+#### Breaking changes
+
+* **Schema Serialization**: Adapt to strict JSON coercion for inputs and outputs (Decimals, UUIDs, datetimes, Enums now serialize to primitives), and ensure your schemas do not pass un-coercible values which now trigger hard serialization errors.
+* **Dev UI Config**: Update your setup to retrieve the dev UI runtime configuration directly from the server instead of reading it from a static file.

 ### ⚠ BREAKING CHANGES
 
-* Coerces validated schema inputs and outputs (Decimal, datetime, UUID, Enum) to JSON primitives (str, int) via mode='json'. This affects in-memory node outputs as well as llm_agent output_key state and agent_tool results (bare Decimal dumps to str), as well as node inputs when a dict input_schema is used (such as with parameter_binding='node_input'). Additionally, validating against a dict or types.Schema now raises a hard failure (PydanticSerializationError) on values that Pydantic cannot coerce, where un-coercible values passed through before.
