Changelog

Milestones, not a marketing calendar.

Versions are presentation-layer markers, not published package versions. Dates are the day the work landed. Each entry states only what the source trees implement.

Current

The Rust tree

  1. v0.15.0 ·

    Docs checked against their sources

    • fixed — Every /docs article is re-checked against the ABI, WDBX and Gama READMEs and carries the date of that review.
    • changed — Each article renders its own reference material (MCP tools, site surfaces, WDBX V2 downloads) from the same records as the /docs hub, so the two cannot disagree.
    • fixed — The MCP article lists all twelve contract-covered tools; WDBX V2 is described as the earlier Rust project it documents, not a Zig mirror.

  2. v0.14.0 ·

    First-party sign-in; MCP over HTTP+SSE

    • changed — quesar.cloud leaves the Grok App Builder: sandbox tooling and platform chrome removed, bun and TypeScript throughout.
    • added — Sign-in is first-party Better Auth: email and password, passkeys, and Google, Apple or X when configured.
    • added — abi-mcp's optional loopback listener serves persistent MCP 2024-11-05 HTTP+SSE sessions; POST /message without a session keeps the one-shot reply. Not Streamable HTTP.

  3. v0.13.0 ·

    One site for MLAI and Quesar

    • changed — The MLAI corporate site is merged into quesar.cloud, which becomes the only MLAI and Quesar site; the old repository is archived.
    • added — Chat audits and workspace tokens sealed with AES-256-GCM; account deletion purges per-user data.
    • added — https://quesar.cloud serves the static build from GitHub Pages.

  4. v0.12.0 ·

    Research records pinned to source

    • added — Research publications re-reviewed against pinned ABI and WDBX commits, each with its status, limitations and review date.

  5. v0.11.0 ·

    WDBX becomes its own substrate

    • changed — The WDBX crates are extracted from ABI into the wdbx workspace with history preserved; the abi- crate prefix is kept deliberately and ABI builds against it as a sibling.

  6. v0.10.0 ·

    ABI rewritten in Rust

    • changed — The ABI runtime lands as a nightly-Rust workspace; the Zig tree is torn down. ./tools/check.sh is the validation gate and ./tools/cargo.sh the pinned Cargo wrapper.

Archive

Before the Rust rewrite

These entries describe the superseded Zig implementation. They are kept for provenance and are not current build or source guidance.

Show the 9 Zig-era entries

  1. v0.9.0 ·

    Zig 0.17-dev migration begins

    • changed — Runtime migration to Zig 0.17.0-dev started: std.process.Init entry-point pattern, argsAlloc removal, allowlist-only environString.
    • added — Framework spec pages published on the docs site, including the canonical Abbey–Aviva–Abi specification.
    • fixed — JSON-RPC envelope generation corrected in protocol tooling — responses now always emit complete closing frames.

  2. v0.8.0 ·

    Abbey training pipeline

    • added — Full Zig + MLX training stack: GQA transformer (LLaMA-style, 22 layers, 16Q/4KV heads), BPE tokenizer with fill-in-middle.
    • added — LoRA fine-tuning, speculative decoding, sliding-window KV cache, streaming data loader, HuggingFace export, inference REPL.
    • changed — AdamW with cosine-warmup learning rate schedule standardized across training configs.
    • fixed — Known pending: mlx_value_and_grad hookup awaits a stable C gradient ABI in MLX ≥ 0.23.

  3. v0.7.0 ·

    Production infrastructure expansion

    • added — Auth, middleware, and hosted-operation work moved onto the verification roadmap instead of public claims copy.
    • changed — Deployment language now separates local-first implementation from future managed-service direction.
    • fixed — Public collateral no longer presents security or disaster-recovery behavior without linked evidence.

  4. v0.6.0 ·

    Performance tooling & test milestone

    • perf — SIMD CPU detection selects AVX-512 / NEON paths at startup; memory pooling and profiling hooks land in runtime/.
    • added — Evidence tracking introduced for benchmarks, source links, and verification gaps.
    • changed — Scheduler and allocator language now points readers back to source-backed status.

  5. v0.5.0 ·

    Zig 0.16 — the Writergate migration

    • changed — Migrated 95 files to the vtable-based std.io.Reader / Writer interfaces; explicit buffer ownership throughout.
    • changed — Standardized ArrayListUnmanaged.empty initialization and explicit allocator passing at every call site.
    • added — CI toolchain pinning with a fail-fast version gate mirroring build.zig.zon.

  6. v0.4.0 ·

    WDBX verification track

    • changed — Distributed coordination language moved from shipped-feature copy to roadmap/evidence language.
    • added — Query routing remains visible in the browser demo as a miniature, not a production cluster claim.
    • perf — Performance language now requires repeatable benchmark scripts before exact public numbers.

  7. v0.3.0 ·

    GPU backend matrix

    • changed — Metal, CUDA, Vulkan, WebGPU, and FPGA are presented as targets unless implementation evidence is linked.
    • added — CPU/SIMD remains the portable baseline for public-facing language.
    • perf — Transfer and kernel speedups require source-backed measurements before publication.

  8. v0.2.0 ·

    Storage engine core

    • added — HNSW approximate nearest-neighbor index tuned for cache locality.
    • added — MVCC snapshot reads — writers never block readers; block-chained WAL for tamper-evident history.
    • changed — Security language now describes verification requirements rather than unsupported guarantees.

  9. v0.1.0 ·

    Initial public release

    • added — ABI Agent + WDBX database open-sourced under Apache-2.0 — Zig core, persona scaffolding, vector storage.
    • added — Multi-provider LLM module: OpenAI, Anthropic, and local Ollama endpoints.
