XYZ.js v1.8

Package version: 1.8.0, Apache-2.0. GitHub release only; no npm publication.

P40 — Rendering and regression

• Native adjacent-sprite batching, particle upload reuse and rendering metrics.
• Built-root Canvas2D / WebGL2 / WebGPU regression and scoped residency estimates.

P41 — Authoring and device flow

• Retained UI layout/widgets, semantic focus/modal navigation and prioritized input contexts.
• Decoded/native resource budgets, idle eviction and chunked warmup protecting scene ownership.
• Typed factories, validated content graphs and Authoring Lab.

P42 — Playable reference and advanced profiles

• Native GPU skinning/animated bounds, supplied mip levels and capability-gated compressed textures; native KTX2 opt-in.
• Primitive 3D rigid dynamics/contacts/queries and capsule movement; authored grid/graph A* navigation.
• Animation masks, reference-relative additive layers, synchronized blend trees and two-bone IK.
• Complete Beacon Run: loading/retry, sound or muted play, pause/settings, four-beacon extraction, win/lose, local save/reload/restart and teardown.

Verification and boundaries

• Known hosted CI failure: main CI passed toolchain checks, mandatory example smoke, and Canvas2D/WebGL2 deep regression, but failed the WebGPU adjacent-sprite pixel check on Ubuntu (transparent black instead of the expected tint/opacity). A WebGPU device-loss recovery failure was also logged. The cause is not established; this is not an Ubuntu WebGPU pass. The separate release workflow succeeded.
• Hosted release workflow passed its independent Ubuntu toolchain, tests, build, packaging and publication.
• Published assets were downloaded: SHA256SUMS and both GitHub asset digests verified; the published archive passed the same actual Node ESM consumer physics/navigation/cleanup and vendor-byte checks.
• Local Node 26.7.0 / pnpm 12.6.0: frozen install, typecheck, 79 files / 678 tests, lint, build and format check passed.
• Extracted public Node ESM package exercised real physics/navigation/cleanup; all 14 official OPM vendor files matched byte-for-byte.
• P40–P42 headless Chromium 153 / macOS arm64 evidence covers three-backend regression, GPU/GL native pixel/recovery fixtures, and complete Beacon Run interaction/error flows.
• Canvas2D remains 2D-only and explicitly rejects native-only textures/3D gameplay. Bounded profiles are not full upstream parity, cross-browser/physical-device certification or performance claims. Compressed pixel evidence covers BC1, not every advertised format. No bundled Basis/Draco codec or new runtime dependency.
• Detailed evidence and limitations: ACCEPTANCE.

Assets

• xyz.js-1.8.0.tgz: complete dist/ tree, including official OPM license/manifest/worklet assets.
• SHA256SUMS: release archive checksum.

Deploy the complete dist/ tree, including dist/vendor/opm/; do not copy only its entry point. Historical releases remain unchanged.

XYZ.js v1.7

Full Changelog: v1.6...v1.7

XYZ.js v1.6

v1.6

• 新增：範例目錄頁 examples/（pnpm examples 啟動並開啟，可依功能篩選、逐 backend 開啟）。
• 新增 11 個功能範例：physics2d、particles2d、tilemap2d、transitions2d、ui2d、input-lab、audio-lab、pbr3d、instancing3d、picking3d、gltf3d。
• 引擎原始碼與 dist/ 與 v1.5.2 相同；套件版本為 1.6.0。
• 文件：README、USAGE（中／英）、PLAN、AGENTS 同步範例清單。

驗證

各範例在其支援的 backend 上於 managed headless Chromium 逐一開啟並檢查 console；目前 lint／format／typecheck 通過、49 檔／340 測試通過。

已知限制／未驗證

audio-lab 與 gamepad 路徑只以狀態讀數驗證（未聽到聲音、無實體手把）。world-space ParticleEmitter 置於 additive IsolatedGroup2D 內在 Canvas2D 探測中不會繪出，particles2d 的火焰因此使用 local space。未做跨瀏覽器驗證。
