 # CHANGELOG - go/js
 
+## v1.5.6 (2026-06-21)
+- **可变参数桥接修复**: `wrapGoFunc` 修复对 Go 可变参数（`...any`）的桥接处理。之前将 JS 剩余参数错误打包为单一切片元素，导致 `Call` 二次嵌套；现在改为逐个追加到 `goArgs` 尾部，由 `reflect.Call` 自动构建可变切片，确保 JS 调用 `redis.Do('HSET', a, b, c)` 正确展开。
+- **新增测试**: `TestBridgeVariadic` 覆盖可变参数 0/1/多参数场景。
+
 ## v1.5.5 (2026-06-21)
 - **JS 对齐**: 重构 JS 运行时的报错堆栈提取逻辑，采用高效的字符解析替换正则表达式，并支持 `jsmod.MakeError` 错误包装在桥接层还原出真实的 Go 运行时调用堆栈。
 - **依赖更新**: 升级依赖 `jsmod` 至 `v1.5.3`，`cast` 至 `v1.5.3`，`log` 至 `v1.5.8`。
