Weaviate 1.20 Release

Weaviate 1.20 introduces several new features including multi-tenancy, PQ + Re-scoring, Autocut, search re-ranking, a new hybrid search ranking algorithm, and more. Multi-tenancy allows for efficient storage of data from millions of tenants in one setup. PQ + Re-scoring improves vector search speed with minimal impact on accuracy. Autocut enables users to set a threshold for the number of result groups retrieved. Search re-ranking introduces rerankers for improved final results sets, and a new hybrid search ranking algorithm is introduced for more nuanced ranking of objects.
