# CHANGELOG - apigo.cc/go/vision
|
||||
|
||||
## v1.5.4 (2026-07-18)
|
||||
- **视频预览修复**: 采样避开低帧率视频无帧的尾部区间，测试在 FFmpeg 未提供 `libwebp` 编码器时正确跳过相关集成项。
|
||||
- **依赖校验修复**: 重新整理模块图并补齐 checksum。
|
||||
|
||||
## v1.5.3 (2026-06-21)
|
||||
- **JS 对齐**: 重构 JS 导出为具名函数，并引入 `jsmod.MakeError` 动态包装错误以获取调用栈。
|
||||
- **依赖更新**: 升级依赖 `jsmod` 至 `v1.5.3`，`cast` 至 `v1.5.3`，`rand` 至 `v1.5.3`，`encoding` 至 `v1.5.4`，`safe` 至 `v1.5.2`，`file` 至 `v1.5.5`。

# Testing @go/vision
|

## v1.5.4 验证
|
||||
- 全量测试与图像处理基准测试通过；FFmpeg 能力相关用例按本机编码器能力执行。
|
||||
|
||||
`go/vision` 拥有完善的单元测试覆盖，确保在各种图像处理场景下的稳定性。
