Breaking Changes

●Issue #1

The autogen_magentic_one package has been removed. Users should migrate to the integrated agent implementations within the main autogen packages.

Migration Steps

  1. 1
    To enable streaming in AssistantAgent, set model_client_stream=True during initialization.
  2. 2
    To handle streaming output manually, listen for the autogen_agentchat.messages.ModelClientStreamingChunkEvent type.
  3. 3
    For R1 models, configure the model_info with 'family': ModelFamily.R1 to access the .thought field.
  4. 4
    Remove any dependencies on the deprecated autogen_magentic_one package.

Release Summary

This release introduces token streaming for AgentChat, support for R1-style reasoning 'thought' blocks, and the ability to create FunctionTools from partial functions.
