Important Changes
* `run` and `run_stream` now support a list of messages as `task` input.
* Introduces `AgentEvent` union type in AgentChat, for all messages that are not meant to be consumed by other agents. Replace `AgentMessage` with `AgentEvent | ChatMessage` union type in your code, e.g., in your custom selector function for `SelectorGroupChat` and processing code for `TaskResult.messages`.
* Introduce `ToolCallSummaryMessage` to `ChatMessage` for tool call results from agents. Read [AssistantAgent Doc](https://microsoft.github.io/autogen/0.4.0.dev12/reference/python/autogen_agentchat.agents.html#autogen_agentchat.agents.AssistantAgent)
* Introduce `ModelContext` parameter for `AssistantAgent`, allow usage of [`BufferedChatCompletionContext`](https://microsoft.github.io/autogen/0.4.0.dev12/reference/python/autogen_core.model_context.html#autogen_core.model_context.BufferedChatCompletionContext) to limit context window size sent to model.
* Introduce `ComponentConfig` and add configuration loader for `ChatCompletionClient`. See [Component Config](https://microsoft.github.io/autogen/0.4.0.dev12/user-guide/core-user-guide/framework/component-config.html)
* Moved `autogen_core.tools.PythonCodeExecutorTool` to `autogen_ext.tools.code_execution.PythonCodeExecutionTool`.
* Documentation updates.

Upcoming Changes
* Deprecating `message_handler`. Use `event` or `rpc` to annotate handlers instead. `message_handler` will be kept with a deprecation warning until further notice. 4828
* Token counting mechanism bug fixes 4719

**Full Changelog**: https://github.com/microsoft/autogen/compare/v0.4.0.dev11...v0.4.0.dev12

Important Changes:

1. `autogen_agentchat.agents.AssistantAgent` behavior has been updated in dev10. It will not perform multiple rounds of tool calls -- only 1 round of tool call, followed by an optional reflection step to provide a natural language response. Please see the [API doc for `AssistantAgent`](https://microsoft.github.io/autogen/dev/reference/python/autogen_agentchat.agents.html#autogen_agentchat.agents.AssistantAgent).
2. Module renamings:
- `autogen_core.base` --> `autogen_core`
- `autogen_core.application.SingleThreadedAgentRuntime` --> `autogen_core.SingleThreadedAgentRuntime`.
- `autogen_core.application.logging` --> `autogen_core.logging`.
- `autogen_core.components.*` --> `autogen_core.*`, for `models`, `model_context`, `tools`, `tool_agent` and `code_executor`.
- `autogen_core.components.code_executor.LocalCommandLineCodeExecutor` --> `autogen_ext.code_executors.local.LocalCommandLineCodeExecutor`
- `autogen_agentchat.task.Console` --> `autogen_agentchat.ui.Console`.
- `autogen_agentchat.task.<termination conditions>` --> `autogen_agentchat.conditions.<termination_conditions>`.
- `autogen_ext.models` gets divided into `autogen_ext.models.openai`, `autogen_ext.models.replay`.
- `autogen_ext.agents` gets divided into separate submodules for each extension agent class.
- `autogen_ext.code_executors` gets divided into separate submodules for each executor class.
