  "summary": "Change log Features ☝️ 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 ] #9669 , #9684 , #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 ] #9683 - Allow \"match\": {\"prefix\": \"...\"} in filter to match keywords by prefix, must be enabled in keyword index. [ docs ] #9661 - Per-query IDF corpus for sparse vector search [ docs ] #9899 - Slice filtering condition: sliced scroll / deterministic sampling [ docs ] #10035 - Global quota API [ docs ] #9338 - Add routing token for deterministic read routes [ docs ] Improvements 👈 #9113 - Use batched reads in vector and payload storage #9409 - Utilize io_uring for payload storage #9448 - Lower default update queue length, reduce from 1M to 200 #9500 - Use Entry API to avoid redundant map double-lookups, improving performance #9332 - Enable single file mmap vector storage by default for immutable segments #9376 - Add option to explicitly disable BM25 stemmer;
