Summary

This release introduces built-in support for MCP and HTTP tools, enhances MagenticOne and SelectorGroupChat for smaller/text-only models, and simplifies Gemini model integration.

Migration Steps

  1. To use MCP tools, install dependencies: pip install mcp-server-fetch autogen-ext[mcp].
  2. To use HTTP tools, install dependencies: pip install autogen-ext[http-tool].
  3. Update Gemini client implementations to simplify initialization by removing redundant model_info and base_url parameters.
