## 1.0.0
### ⚠ BREAKING CHANGES
* Evaluation dataset schema is finalized with strong-type pydantic models.
(previously saved eval file needs re-generation, for both adk eval cli and
the eval tab in adk web UI).
* `BuiltInCodeExecutor` (in code_executors package) replaces
`BuiltInCodeExecutionTool` (previously in tools package).
* All methods in services are now async, including session service, artifact
service and memory service.
* `list_events` and `close_session` methods are removed from session service.
* agent.py file structure with MCP tools are now easier and simpler ([now](https://github.com/google/adk-python/blob/3b5232c14f48e1d5b170f3698d91639b079722c8/contributing/samples/mcp_stdio_server_agent/agent.py#L33) vs [before](https://github.com/google/adk-python/blob/a4adb739c0d86b9ae4587547d2653d568f6567f2/contributing/samples/mcp_agent/agent.py#L41)).
Old format is not working anymore.
* `Memory` schema and `MemoryService` is redesigned.
* Mark various class attributes as private in the classes in the `tools` package.
* Disabled session state injection if instruction provider is used.
(so that you can have `{var_name}` in the instruction, which is required for code snippets)
* Toolbox integration is revamped: tools/toolbox_tool.py → tools/toolbox_toolset.py.
* Removes the experimental `remote_agent.py`. We'll redesign it and bring it back.
### Features
* Dev UI:
* A brand new trace view for overall agent invocation.
* A revamped evaluation tab and comparison view for checking eval results.
* Introduced `BaseToolset` to allow dynamically add/remove tools for agents.
* Revamped MCPToolset with the new BaseToolset interface.
* Revamped GoogleApiTool, GoogleApiToolset and ApplicationIntegrationToolset with the new BaseToolset interface.
* Resigned agent.py file structure when needing MCPToolset.

* Various docstring improvements.
* Various UI tweaks.
* Various bug fixes.
* Update various contributing/samples for contributors to validate the implementation.
## 0.5.0
### ⚠ BREAKING CHANGES
* Updated artifact and memory service interface to be async. Agents that
interact with these services through callbacks or tools will now need to
adjust their invocation methods to be async (using await), or ensure calls
are wrapped in an asynchronous executor like asyncio.run(). Any service that
extends the base interface must also be updated.
### Features
* Introduced the ability to chain model callbacks.
* Added support for async agent and model callbacks.
* Added input transcription support for live/streaming.
* Captured all agent code error and display on UI.
* Set param required tag to False by default in openapi_tool.

* Updated the contributing guide.
* Docstring improvements, typo fixings, GitHub action to enforce code styles on formatting and imports, etc.
## 0.4.0
### ⚠ BREAKING CHANGES
* Set the max size of strings in database columns. MySQL mandates that all VARCHAR-type fields must specify their lengths.
* Extract content encode/decode logic to a shared util, resolve issues with JSON serialization, and update key length for DB table to avoid key too long issue in mysql.
* Enhance `FunctionTool` to verify if the model is providing all the mandatory arguments.
### Features
* Update ADK setup guide to improve onboarding experience.
* feat: add ordering to recent events in database session service.
* feat(llm_flows): support async before/after tool callbacks.
* feat: Added --replay and --resume options to adk run cli. Check adk run --help for more details.
* Created a new Integration Connector Tool (underlying of the ApplicationIntegrationToolSet) so that we do not force LLM to provide default value.
### Bug Fixes
* Don't send content with empty text to LLM.
* Fix google search reading undefined for `renderedContent`.
### Miscellaneous Chores
* Docstring improvements, typo fixings, github action to enfore code styles on formatting and imports, etc.
## 0.3.0
### ⚠ BREAKING CHANGES
* Auth: expose `access_token` and `refresh_token` at top level of auth
credentials, instead of a `dict`
([commit](https://github.com/google/adk-python/commit/956fb912e8851b139668b1ccb8db10fd252a6990)).
### Features

### Features
* `adk` CLI:
* Introduce `adk create` cli tool to help creating agents.
* Adds `--verbosity` option to `adk deploy cloud_run` to show detailed cloud
run deploy logging.
* Improve the initialization error message for `DatabaseSessionService`.
* Lazy loading for Google 1P tools to minimize the initial latency.
* Support emitting state-change-only events from planners.
* Lots of Dev UI updates, including:
