Weaviate released version 1.39, promoting query-time Boost API and MMR diversity ranking to GA, introducing 4-bit residual quantization (RQ), and shipping an experimental clientless Search REST interface.
Key Takeaways
- ✓Boost API reorders search rankings without dropping hit candidates for flexible RAG business rules;
- ✓MMR diversity ranking reaches GA, preventing near-duplicate results in hybrid keyword and vector queries;
- ✓4-bit RQ combined with automated HNSW snapshots drastically reduces memory footprint and disk commit overhead.
