 - 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

+- `release.ps1` 打 annotated tag / 自动 commit 改为 UTF-8 消息文件 + `git -F`，避免 Windows PowerShell 按控制台代码页编码 `-m` 参数
+- 验收时 Gitea tag 说明应为「正式发布」，而不是「姝ｅ紡鍙戝竷」；不改写已发布的历史 tag（含 v1.0.86）
+
 ## 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
+- 去掉 `release.ps1` 里通过 `cmd /c` 调 git 的写法；中文 tag 说明在部分 Windows 控制台代码页下仍可能乱码，见 1.0.87
