v1.1.1

STK-Vector-64 v1.1.1

Syzygy root ranking now respects UCI searchmoves and passes earlier repetition
history to DTZ probing. The shipped STK-HalfKA topology, weights and standard
search fingerprints with tablebases disabled are unchanged.

Changes since v1.1.0:

• DTZ and WDL fallback rank only allowed legal root moves, including when all
  globally optimal moves are excluded by the caller.
• DTZ receives repetitions since the last capture or pawn move, including an
  earlier cycle when the current root has not repeated. A FEN alone cannot
  reconstruct game history; supply the moves in the UCI position command.
• Adapter regression tests and optional real-table tests cover restricted
  search, repetition history, fallback and the fifty-move boundary.
• Release publication finds authenticated drafts omitted by GitHub's tag
  endpoint while retaining source, checksum and upload verification.
• Corrected stale Syzygy documentation and updated the README video preview.

Known material-adjudication, network-replacement and Syzygy boundaries remain;
read LIMITATIONS.md in the tagged source. Matching external WDL/DTZ files are
required for tablebase coverage and are not bundled. There is no absolute Elo
or general speedup claim.

Download release-notices.zip with the executable. release-source.tar.gz
contains the corresponding source. Verify downloads with SHA256SUMS.
Per-platform .build.json files and release-builds.json identify the
source, toolchain, flags, embedded network and UI bundle.

Every platform ships six executables (.exe last on Windows):

Suffix	Capability
(none)	Standard chess with classical evaluation.
-nnue	Standard chess with the shipped network embedded.
-all	Standard chess with NNUE; crazyhouse and bughouse use classical evaluation.
-variants	Drop variants with classical evaluation, no embedded net.
-validator	Legality, terminal and FEN queries as one-line JSON.
-viz	Vector Scope with the network and UI embedded.

x86-64-v3 needs AVX2 and BMI2; x86-64-v2 needs SSE4.2 and POPCNT.
Windows requires AVX2. arm64-dotprod requires ARMv8.2 dot-product;
plain arm64 targets ARMv8-A. Linux assets are built on Ubuntu 24.04;
compiler/runtime and macOS deployment details are in the build records.

The notices archive preserves component terms and the model card;
it does not establish missing network training provenance or grant new rights.

v1.1.0

STK-Vector-64 v1.1.0

Vector Scope, shared NNUE training tools and release provenance join fixes for
threaded search, deferred NNUE accumulators, datagen recovery and append-safe
recording. The shipped STK-HalfKA topology and weights are unchanged.

Highlights since v1.0.0:

• Coherent transposition-table snapshots and consistent classical evaluation
  in drop-variant helper threads.
• Deferred big-network accumulator updates when optional evaluation gates skip
  the big network; shared search/depth limits and explicit browser worker stacks.
• Validated HTTP/WASM dataset recovery, append-preserving recordings and
  deterministic, integrity-checked RL input preparation.
• Shared training/export/parity tools, perft divide, guarded benchmark matrix,
  refreshed Vector Scope UI and current architecture/protocol documentation.
• Six-platform release checks with exact-commit CI gates and verified assets.

Known material-adjudication, network-replacement and Syzygy boundaries remain;
read LIMITATIONS.md in the tagged source. Browser recovery does not add durable
storage across reloads. There is no absolute Elo or general speedup claim.

Full Changelog: v1.0.0...v1.1.0

v1.0.0

Each platform ships up to six binaries, named <platform> plus the
suffix below (.exe last on Windows).

Suffix	What it is
(none)	Classical evaluation, no net. Smallest, most portable.
-nnue	Standard chess, net embedded. Strongest at chess.
-all	-nnue plus crazyhouse and bughouse. Use this for variants.
-variants	Drop variants on the classical evaluation, no net. Used for SPRT.
-validator	Legality, terminal and FEN queries as one-line JSON. No search, no net.
-viz	Vector Scope, the live NNUE visualizer. Net and UI in one file.

Pick by CPU: x86-64-v3 needs AVX2 (2015+), x86-64-v2 needs SSE4.2
(2009+), arm64-dotprod needs ARMv8.2 dot-product.
