0.1.1 - 2026-06-23

Release Notes

Fixed

• Removed local absolute llama.cpp/model paths from scripts and documentation
  included in the crates.io source package. Runtime benchmark scripts now use
  documented environment variables for local model locations.

0.1.0 - 2026-06-22

Release Notes

Added

• Added a standalone generated public fixture corpus and manifest so QATQ can
  benchmark and validate itself without external runtime captures.
• Added explicit benchmark gate policies for production KV throughput readiness
  competitive compression, and fixed-us latency-budget analysis.
• Added production chunk metadata/restore helpers for runtime integrations.
• Added native exact f16 and bf16 tensor byte support.
• Added direct external KV/tensor benchmark adapters and runtime evidence
  documentation for exported LLM cache migration artifacts.
• Added deterministic KV stress coverage and scheduled fuzzing workflow
  scaffolding.
• Added cargo-dist GitHub Release automation with cross-platform archives,
  checksums, shell installers, and signed/notarized macOS release artifacts.
• Added manual crates.io publication workflow guarded by the crates-io
  environment and an explicit expected-version check.
• Added a technical whitepaper connecting the original quaternion TurboQuant
  foundation to the current exact QATQ/QATC product surface.
• Added open-source readiness files, issue/PR templates, Dependabot
  configuration, and QATQ brand assets.

Changed

• Made qatq-exact and the QATC container the primary exact QATQ product
  surface.
• Moved the crate to Rust 2024 edition with an explicit MSRV/toolchain record.
• Scoped lossless claims to QATQ exact and QATC, with lossy Phase 1 and
  TurboQuant paths retained as research/baseline comparators.
• Recorded API/CLI freeze status for the initial public release.

QATQ v0.1.0-rc1

QATQ v0.1.0-rc1 is a source release candidate for review from the tagged repository state. It is not a crates.io publish, and no crate, binary, or container artifacts are being published yet.

Highlights:

• Phase 2 exact/lossless path: byte-plane block/RLE candidates, adjacent-bit delta-XOR byte-plane RLE probing, raw-bits fallback, and the QATC large-tensor container path.
• Public fixtures: deterministic generated fixture corpus in fixtures/generated with fixtures/public.manifest; four fixtures, 40,960 values, and 163,840 bytes covered by docs/PUBLIC_FIXTURE_AUDIT.md.
• CI and fuzz scaffold: GitHub Actions CI plus cargo-fuzz targets for decode payload handling and Phase 2 round-trip coverage.
• Baselines: public comparative codec tables for raw f32, zstd, lz4, fp8-e4m3, lossy-i4, turboquant-q4, phase1-q4, and Phase 2 lossless modes.
• Quality-proxy report: deterministic codec-level inner-product probes in docs/PUBLIC_QUALITY_EXPERIMENTS.md; this is not a model-quality or perplexity claim.

Release-review scope:

• Install/build from tag only.
• Run docs/RELEASE_CHECKLIST.md from a clean clone.
• Confirm docs, examples, fixture generation, package contents, and CLI commands work from the tagged state.

Known final-v0.1.0 blockers:

• Keep crates.io publishing deferred until public API names are stable.
• Add longer or scheduled fuzzing.
• Add at least one end-to-end model/task quality experiment before making stronger QATQ-vs-TurboQuant quality claims.
• Keep lossless claims limited to Phase 2.
