LlamaIndex has released version 0.11 of its Python framework, introducing several significant updates and enhancements since version 0.10. The most notable changes include the introduction of Workflows, an event-driven architecture aimed at building complex generative AI applications, and the enhanced Property Graph Index for better support of property graphs. The update also features improved observability with new instrumentation capabilities, a substantial reduction in the package size by 42% by removing OpenAI as a core dependency, and making Pandas optional. Additionally, the update includes async streaming support, a Structured Planning Agent, Function Calling LLM, and a Chat Summary Memory buffer to enhance functionality. However, version 0.11 involves breaking changes such as transitioning to Pydantic V2 for compatibility with frameworks like FastAPI, and the removal of the ServiceContext and LLMPredictor, requiring users to adapt to the new Settings and LLM class.
