 # CHANGELOG
 
+## 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`，`shell` 至 `v1.5.3`，`safe` 至 `v1.5.2`，`id` 至 `v1.5.4`，`file` 至 `v1.5.5`，`config` 至 `v1.5.3`，`log` 至 `v1.5.8`。
+
 ## v1.0.4 (2026-05-31)
 - **新增**: 注册到 `jsmod`。支持低代码环境下的邮件发送与接收。
   - 提供 `send`, `recv` 默认快捷操作。

+- **单元测试**: `go test -v ./...` 通过 (2026-06-21)。
 - **并发安全性**: 经过 `sync.RWMutex` 保护，支持多协程下注册 Handler 及发送。
+- **JS 错误调用栈**: JS 桥接层改用具名导出并使用 `jsmod.MakeError` 包裹错误，确保 JS 抛出异常时携带准确的 Go 运行时堆栈。
