 # Changelog
 
+## [0.4.1] - 2026-09-06
+
+### Fixed
+
+- Fixed Rhino 3DM models loading layers and object counts but showing a blank viewport when Brep/Extrusion objects had no embedded Rhino render mesh.
+- Updated the bundled SpatialViewer.3DMCore to 1.0.2 with semantic Brep and Extrusion fallback tessellation.
+- Moved prepared 3DM render-scene construction off the WinUI UI thread so NURBS tessellation no longer freezes the window after loading.
+- Replaced per-triangle Win2D CanvasGeometry creation with batched per-instance paths and bounded frame budgets.
+- Added dark/light canvas contrast correction so black or near-black Rhino layer colors remain visible on dark backgrounds without mutating source colors.
+- Bounded selection highlighting to avoid allocating very large edge hash sets for complex meshes.
+- Mouse-wheel zoom now remains available regardless of the active Rhino navigation tool.
+
+### Preserved
+
+- CAD viewer rendering, CadCore runtime behavior, CAD toolbar/view controls, title bar, tabs, navigation, Projects, Favorites, and existing shell effects remain unchanged.

+
+v0.4.1 is a hotfix for the blank Rhino viewport and UI hangs found during v0.4 field testing.
+
+## Fixes
+- 3DMCore 1.0.2 now generates display meshes from semantic Brep and Extrusion geometry when Rhino render meshes are not stored in the file.
+- Prepared 3DM render-scene/NURBS tessellation runs off the WinUI UI thread to prevent the window from becoming unresponsive after loading.
+- Win2D rendering now batches triangles per Mesh instance instead of creating a CanvasGeometry for every triangle, with bounded fill/wire/curve/point frame budgets.
+- Black and near-black Rhino layer colors receive display-only contrast correction on dark canvases without changing source model colors.
+- Complex Mesh selection highlighting uses bounded batched wire drawing instead of allocating huge edge hash sets.
+- Mouse-wheel zoom works regardless of the active Select/Orbit/Pan tool.
+
+## Preserved
+This hotfix does not modify the CAD rendering path, CadCore, CAD toolbar behavior, title bar, tabs, navigation, Projects, Favorites, or existing theme/shell effects.

+v0.4.1 は v0.4 の実機確認で判明した Rhino の黒画面と応答停止を修正するホットフィックスです。
+
+## 修正
+- Rhino render mesh が保存されていない 3DM でも、3DMCore 1.0.2 が Brep / Extrusion のセマンティック形状から表示メッシュを生成します。
+- 3DM render scene の NURBS テセレーションを WinUI UI スレッド外へ移し、読み込み後の「応答なし」を防止します。
+- Win2D 描画を三角形ごとの CanvasGeometry 生成から Mesh instance 単位のバッチ描画へ変更し、1 フレームの描画量に上限を設けました。
+- 暗いキャンバス上の黒・暗色 Rhino レイヤー色に表示用コントラスト補正を適用します。元のモデル色は変更しません。
+- 複雑な Mesh の選択ハイライトを上限付きバッチ線画に変更しました。
+- 選択/回転/パンのどのツールでもホイールズームを利用できます。
+
+## 維持される機能
+CAD ビューアー、CadCore、CAD ツールバー、タイトルバー、タブ、ナビゲーション、プロジェクト、お気に入り、テーマの既存動作は変更しません。

+v0.4.1 是针对 v0.4 实机验收中 Rhino 黑屏与未响应问题的热修。
+
+## 修复
+- 3DM 文件即使未保存 Rhino render mesh，Brep 与 Extrusion 也会由 3DMCore 1.0.2 从语义几何生成显示网格。
+- 3DM render scene 的曲面离散移出 WinUI UI 线程，避免模型载入完成后窗口长时间“未响应”。
+- Win2D 视口由逐三角创建 CanvasGeometry 改为按 Mesh instance 批量绘制，并设置单帧 fill / wire / curve / point 预算。
+- 黑色或近黑 Rhino 图层颜色在黑色画布上自动做显示对比度修正，不修改原始模型颜色。
+- 复杂 Mesh 的选择高亮改为有预算的批量线框，避免生成巨型边集合。
+- 鼠标滚轮缩放不再受当前选择/旋转/平移工具限制。
+
+## 保持不变
+本热修不修改 CAD 看图链、CadCore、CAD 工具条及既有标题栏、标签页、导航、项目、收藏和主题效果。
