package snkv

Changelog

0.3.1 - 2026-10-25

Added

• Core package is available on Windows again.
• Windows-only test for the vector stub API.

Changed

• Vector implementation is selected at build time: real implementation on Unix, stub on Windows.
• Vector tests are skipped on Windows.
• Vendored FP16 and replaced the compiler-specific _Float16 fallback in the vector build.

0.3.0 - 2026-10-23

Added

• Snkv.Vector bindings for SNKV HNSW vector search.
• Vector tests for distance spaces, TTL, sidecar persistence, encryption, errors, batch duplicates, and larger indexes.
• doc/vector_api.md.
• Portable vector build via Dune foreign libraries on Linux and macOS.

Changed

• Kv.error_code now includes vector-specific codes (DimMismatch, DtypeMismatch, SpaceMismatch, IndexDropped, IndexEmpty, BadVector).
• Vector API uses Kv.result and Kv.error_code, without trailing unit arguments.

Notes

• Windows is not supported in the 0.3.x line; the package is marked unavailable on Windows.

0.2.0 - 2026-10-22

Added

• Vendored SNKV v0.8.2 and recorded provenance in lib/snkv.upstream.
• Reproducible vendoring via scripts/update-snkv.sh.
• Low-level config mapping and full_mutex for OCaml 5 domains.
• Error codes from SNKV are propagated to the high-level result API.
• Refcounted handle lifetimes for stores, column families, and iterators.
• New test modules for basic operations, config, TTL, iterators, encryption, errors, and lifetimes.
• doc/compatibility.md and CHANGELOG.md.

Changed

• None filenames open an in-memory database instead of an empty path.
• Encrypted stores now require an explicit filename.
• checkpoint returns (log, ckpt) instead of mutating references.
• Txn.with_transaction rolls back on exceptions.
• C buffers are released with snkv_free.
• High-level open applies the full Config record through kvstore_open_v2.

Fixed

• Missing or incorrect error mapping (Busy, ReadOnly, AuthFailed, NotFound).
• Use-after-free risks around handle finalizers and CF/iterator lifetimes.

0.1.1

• Initial public release.
