 - 小节正文写用户能看懂的变化（新能力、修复、注意事项），避免堆砌内部实现细节
 - 打 tag 前**必须**为即将发布的版本新增一节；找不到匹配小节时，本次发布不会更新 changelog 字段
 
+## 1.0.86
+
+- 修复 `release.ps1` 在中文 Windows 下经 `cmd /c` 打 annotated tag 时，默认说明「正式发布」被 OEM 代码页转成乱码的问题
+- 改为直接调用 `git.exe` 并按参数数组传 `-m`，commit / tag 中文说明保持 UTF-8；不改写历史 tag
+
 ## 1.0.85
 
 - 新增开发主文 `development/PRODUCT_SURFACES.md`：说明对话 / 数据管理 / 定时任务平级关系、何时走哪个入口、如何做入口定位
