Haystack used to be distributed with the package farm-haystack (which continues to distribute 1.0), but yesterday we release Haystack 2.0 with a new package: haystack-ai

Haystack used to be a framework that centered around semantic search and retrieval, first released in 2020. And while the design allowed us to extend to new LLM technologies, it wasn’t an intuitive developer experience for our users. So we made the decision to completely rewrite the fundamentals of the framework. The new design provides a uniform way for _extending_ the framework. And makes it very transparent how AI components interact with eachother.

The announcement article explains our reasons for this major rewrite.
