Summary

This release introduces concurrent agent execution in GraphFlow and a new OpenAIAgent. It also features experimental callable edge conditions and various improvements to model clients and code executors.

⚠️ Breaking Changes

  • The return type of BaseGroupChatManager.select_speaker has changed from 'str' to 'List[str] | str'. Custom implementations of this method must be updated to support returning a list of agent names to enable concurrent execution.

Migration Steps

  1. Update any custom subclasses of BaseGroupChatManager to ensure the select_speaker method signature matches 'async def select_speaker(self, thread: Sequence[BaseAgentEvent | BaseChatMessage]) -> List[str] | str:'.
  2. If using GraphFlow with callable conditions, note that these are currently experimental and cannot be serialized.

✨ New Features

  • Support for concurrent agents in GraphFlow (fan-out-fan-in patterns).
  • Experimental support for callable conditions (lambdas) in GraphFlow edges.
  • New OpenAIAgent backed by the OpenAI Response API.
  • Support for Streamable HTTP transport in MCP.
  • Added tool_call_summary_msg_format_fct to AssistantAgent.
  • Support for multiple workbenches in AssistantAgent.
  • Auto-delete temporary files option in LocalCommandLineCodeExecutor.
  • Llama API OpenAI-compatible endpoint support in OpenAIChatCompletionClient.
  • Support for Qwen3 in OllamaChatCompletionClient.
  • Implicit AWS credential setting for AnthropicBedrockChatCompletionClient.
  • Structured output support for MagenticOneGroupChat orchestrator.
  • Added created_at timestamp to BaseChatMessage and BaseAgentEvent.
  • Support for Claude Sonnet 4 and Claude Opus 4 models.

🐛 Bug Fixes

  • Fixed 'cannot find next agent' bug in GraphFlow by allowing callable edge conditions.
  • Fixed missing tools in logs.
  • Fixed CodeExecutorAgent prompt misuse.
  • Fixed issue where Async Event Loop could run indefinitely.
  • Fixed missing UserMessage import.
  • Fixed Docker Jupyter code executor to include all output in error output.
  • Fixed parsing of backtick-enclosed JSON.
