Summary

This release improves GraphFlow state persistence and termination logic, adds tool override capabilities to Workbench implementations, and expands model support for Claude and Qwen2.5-VL.

⚠️ Breaking Changes

  • The inner StopAgent has been removed from GraphFlow. The last message will no longer come from StopAgent; instead, check the stop_reason field in TaskResult.
  • GraphFlow now retains execution state after termination conditions are hit, requiring an explicit finish (no available next agents) to reset state automatically.

Migration Steps

  1. Update code that relies on receiving a final message from StopAgent to instead inspect the 'stop_reason' field in the 'TaskResult' object.
  2. Review GraphFlow implementations to ensure logic accounts for state retention between tasks until the graph fully completes.

✨ New Features

  • McpWorkbench and StaticWorkbench now support overriding tool names and descriptions for client-side optimization.
  • Added reflection support for Claude models in AssistantAgent.
  • Added support for Qwen2.5-VL model.
  • Added DuckDuckGo Search Tool and Agent in AutoGen Extensions (Note: subsequent PR in same release notes indicates removal/reversion).
  • Added script for automatic API documentation generation.

🐛 Bug Fixes

  • Fixed GraphFlow to support multiple task executions without requiring an explicit reset.
  • Fixed GraphFlowManager termination to prevent _StopAgent from polluting the conversation context.
  • Fixed function calling support for Llama 3.3.
  • Updated GitHub Models URL to the new endpoint.
  • Modified SingleThreadedAgentRuntime to use subclass checks for factory_wrapper instead of equality.
  • Removed otel-semconv package from core dependencies to streamline requirements.
