  • Python: [BREAKING] Simplify API: ChatAgent -> Agent, ChatMessage -> Message (#3747)
    * [BREAKING] Rename ChatAgent -> Agent, ChatMessage -> Message, ChatClientProtocol -> SupportsChatGetResponse
    
    Simplify the public API by removing redundant 'Chat' prefix from core types:
    - ChatAgent -> Agent
    - RawChatAgent -> RawAgent
    - ChatMessage -> Message
    - ChatClientProtocol -> SupportsChatGetResponse
    
    Also renamed internal WorkflowMessage (was Message in _runner_context) to avoid collision.
    
    No backward compatibility aliases - this is a clean breaking change.

  • Python: [BREAKING] Types API Review improvements (#3647)
    * Replace Role and FinishReason classes with NewType + Literal
    
    - Remove EnumLike metaclass from _types.py
    - Replace Role class with NewType('Role', str) + RoleLiteral
    - Replace FinishReason class with NewType('FinishReason', str) + FinishReasonLiteral
    - Update all usages across codebase to use string literals
    - Remove .value access patterns (direct string comparison now works)
    - Add backward compatibility for legacy dict serialization format
    - Update tests to reflect new string-based types
    
    Addresses #3591, #3615

    - Remove text parameter from ChatResponse.__init__
    - Remove | dict[str, Any] from finish_reason and usage_details params
    - Remove **kwargs from AgentResponse.__init__
    - Both now accept ChatMessage | Sequence[ChatMessage] | None for messages
    - Update docstrings and examples to reflect changes
    - Fix tests that were using removed kwargs
    - Fix Role type hint usage in ag-ui utils
    
    * Remove text parameter from ChatResponseUpdate and AgentResponseUpdate (#3597)
    
    - Remove text parameter from ChatResponseUpdate.__init__
    - Remove text parameter from AgentResponseUpdate.__init__
    - Remove **kwargs from both update classes
    - Simplify contents parameter type to Sequence[Content] | None
    - Update all usages to use contents=[Content.from_text(...)] pattern
    - Fix imports in test files
    - Update docstrings and examples
    
    * Rename from_chat_response_updates to from_updates (#3593)
    
    - ChatResponse.from_chat_response_updates → ChatResponse.from_updates
    - ChatResponse.from_chat_response_generator → ChatResponse.from_update_generator
    - AgentResponse.from_agent_run_response_updates → AgentResponse.from_updates
    
    * Remove try_parse_value method from ChatResponse and AgentResponse (#3595)
    
    - Remove try_parse_value method from ChatResponse
    - Remove try_parse_value method from AgentResponse
    - Remove try_parse_value calls from from_updates and from_update_generator methods
    - Update samples to use try/except with response.value instead
    - Update tests to use response.value pattern
    - Users should now use response.value with try/except for safe parsing
    
    * Add agent_id to AgentResponse and clarify author_name documentation (#3596)
    
    - Add agent_id parameter to AgentResponse class
    - Document that author_name is on ChatMessage objects, not responses
    - Update ChatResponse docstring with author_name note
    - Update AgentResponse docstring with author_name note

    - Update type signatures in _agents.py and _clients.py
    - Add tests for Content input handling
    
    * Fix ChatMessage usage across packages and samples
    
    Update all remaining ChatMessage(role=..., text=...) to use new
    ChatMessage('role', ['text']) signature.
