In the meantime, while there were turf wars being waged in the Autogen arena, CrewAI has been building itself it to much more reliable and fully featured alternative. They have even removed LangChain as a dependency. The close association with LangChain had been a thorn in their side, IMO for some side and a reason for me to opt not to use.
Sad to see these event in the OSS community. I'll be looking at CrewAI for my next projects.
