## 1.0.0
### ⚠ BREAKING CHANGES

(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.

## 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.

* 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.
