Features :point_up:

https://github.com/qdrant/qdrant/milestone/50 - TurboQuant 4-bit as a datatype of primary vector storage. Only store 4-bit quantized vectors and spare disk space on original vectors. [docs]
https://github.com/qdrant/qdrant/pull/9669, https://github.com/qdrant/qdrant/pull/9684, https://github.com/qdrant/qdrant/pull/9950 - Unify definition of memory usage strategy for collection components. Use "memory": "cold" / "cached" / "pinned" to define memory behavior for each individual collection component. Allows for more fine-grained control over memory usage and performance. [docs]
https://github.com/qdrant/qdrant/pull/9683 - Allow "match": {"prefix": "..."} in filter to match keywords by prefix, must be enabled in keyword index. [docs]
https://github.com/qdrant/qdrant/pull/9661 - Per-query IDF corpus for sparse vector search [docs]
https://github.com/qdrant/qdrant/pull/9899 - Slice filtering condition: sliced scroll / deterministic sampling [docs]
https://github.com/qdrant/qdrant/pull/10035 - Global quota API [docs]
https://github.com/qdrant/qdrant/pull/9338 - Add routing token for deterministic read routes [docs]
