# DiskANN v0.61.0 ## Highlights - **Quantization:** Added 3-bit spherical quantization with AVX2 acceleration, faster spherical encoding, and NEON float32 MinMax kernels. - **In-memory indexing (experimental):** Added product quantization and 1-8-bit scalar quantization, unified quantized representations, and AArch64 prefetching. - **Multi-vector search:** Added `i8 x i8` and MinMax8 x MinMax4 MaxSim kernels. - **Fixes:** Preserve virtual start-point out-edges when writing disk indexes, correctly round-trip scalar quantization configurations without standard deviation, and support zero-column mutable matrix iterators. ## Breaking changes and upgrading Changes are concentrated in quantization APIs and experimental/tooling crates. * PQ training (#1467) - Training now returns `BasicTable`. `SimplePivots` was removed. Replace `flatten()` with `view_pivots().as_slice()` and use `pivots_for(chunk)` for per-chunk access. * PQ distance tables (#1458) - Change `ProcessInto` bounds to `ProcessInto<f32>` and calls from `process_into::<Metric>(...)` to `process_into::<Metric, f32>(...)`. * MaxSim kernels (#1429) - Generic kernel/erasure code now requires `T: MaxSimElement` and score buffers of `T::Score` (`f32` for floats, `i32` for `i8`). Update `build_max_sim` error handling from `NotSupported` to `BuildMaxSimError`. * `diskann-inmem` (#1485) - Replace `repr::Spherical` with `repr::Quantized`. Wrap the quantizer in `repr::quantized::spherical::Spherical::new(...)` when configuring it. Configuration and `Rerank` types now live under `repr::quantized`. * `diskann-benchmark-runner` (#1475) - `input::Registered` and public `Registry::input` were removed. Use the concrete `Input` implementation's `tag()` and `example()` methods instead. ## All Changes * Fix serialization round trip for QuantizationType::SQ without standard deviation by @arrayka in #1461 * i8 x i8 MaxSim Kernels by @suri-kumkaran in #1429 * Adding `subview_mut` to `MatrixMut` by @arkrishn94 in #1463 * Add InsertResult::SuccessUpdate by @metajack in #1449 * [diskann-quantization] PQ Infrastructure for `diskann-inmem` by @hildebrandmw in #1458 * [diskann-quantization] Teach PQ training to return a `BasicTable`. by @hildebrandmw in #1467 * [deps] Run `cargo-update` by @hildebrandmw in #1452 * Support zero-column mutable matrix iterators by @arrayka in #1462 * [diskann-quantization] Use `f32::NAN` instead of `core::f32::NAN`. by @hildebrandmw in #1471 * [diskann-wide] Add `V4::new_checked_miri_uncached`. by @hildebrandmw in #1480 * [diskann-wide] Add maddubs intrinsic wrappers to V3 and V4 by @partychen in #1479 * Bump the github-actions group across 1 directory with 5 updates by @dependabot[bot] in #1482 * [benchmark-runner] Simplify Input representation by @hildebrandmw in #1475 * [diskann-quantization] Optimize spherical encoding scale search by @xinyuwen2 in #1478 * [diskann-garnet] Implement XVCREATE, XVIMPORT by @metajack in #1455 * [diskann-garnet] Support configurable start points and allow importing start points by @metajack in #1464 * [diskann-garnet] Add spherical 2-bit and 4-bit quantization by @metajack in #1465 * [deps] Address depandabot issue 32 by @hildebrandmw in #1496 * [diskann-disk] Preserve virtual start point out-edges when writing the disk index by @doliawu in #1483 * [diskann-quantization] Add Neon F32 Minmax Kernels by @pfoxARM in #1431 * [diskann-garnet] Add macOS arm64 support to NuGet publishing by @metajack in #1495 * [diskann-disk] Require start points at index initialization. by @hildebrandmw in #1497 * Expose metric-aware quantizer centroid distance by @cherryrhea in #1395 * [diskann-inmem] Add support for Product Quantization by @hildebrandmw in #1469 * Adds aarch64 prefetching into diskann-vector and diskann-inmem by @pfoxARM in #1408 * [diskann-inmem] Add scalar quantization by @hildebrandmw in #1484 * Bump the github-actions group with 3 updates by @dependabot[bot] in #1505 * [diskann-inmem] Spherical Quantization Round 2 by @hildebrandmw in #1485 * [diskann-quantization] Add SphericalQ 3-bit support and AVX2 kernel by @xinyuwen2 in #1474 * [muilt-vetor] Add standalone MinMax8 x MinMax4 MaxSim kernel by @partychen in #1494 ## New Contributors * @cherryrhea made their first contribution in #1395 **Full Changelog**: v0.60.0...v0.61.0 Co-authored-by: Mark Hildebrand <mhildebrand@microsoft.com>
