 # CHANGELOG - apigo.cc/go/vision
 
+## v1.5.1 (2026-06-08)
+- **JS 对齐 & 智能文档**:
+    - 将所有注册到 `jsmod` 的方法名统一为 PascalCase。
+    - **可选参数优化**: 将 `New` 的 `bg`、`Save` 的 `quality` 等改用指针类型包装。配合最新的 `go/js` 引擎，生成的 `.d.ts` 定义将正确标识为可选参数 `?`，大幅提升 AI 开发效率。
+
 ## v1.0.9 (2026-05-17)
 - **新特性**: 内置全能命令行工具 `vision` (`cmd/vision`)。
 - **功能增强**: `vision.Load` 增加多级环境探测（sips, heif-convert, magick, ffmpeg），完美支持 HEIC 及其网格重构解码。
