 # Changelog
 
+## 1.2.3 - 2026-11-12
+
+### 新增
+
+- 固定截图支持右键菜单：复制、删除、编辑、OCR 与翻译；编辑以当前固定图片重新进入标注器，OCR / 翻译会回到主页面处理。
+
+### 修复
+
+- 修复固定截图被普通窗口遮挡和拖动不跟随的问题：创建固定窗口后重新声明置顶，并禁用图片原生拖拽，让指针拖动始终移动窗口。
+- 修复固定截图右键 OCR / 翻译可能无响应的问题：固定期间不再退出插件主视图，并等待识别处理完成后再关闭固定子窗口，避免宿主回收插件进程或把主窗口保持在 0 高度。
+
 ## 1.2.2 - 2026-11-11
 
 ### 修复

 常见用法举几个例子：
 
 - 想给别人圈重点 → 截图后直接在全屏画面上框选、画矩形/箭头、加文字，再复制成图片发出去。
-- 想把截图钉在屏幕上做参考 → 截图后点「固定」，图片会置顶显示，可拖动、滚轮缩放。

 - 随手截了张图想裁剪、打马赛克 → 用「编辑图片」就地处理。
 - 截图里的字看不清，想变成可复制文本 → 截图后点「图片 OCR」。
 - 遇到一段英文/日文，想看懂 → 选中图片点「翻译」，或直接在输入框里粘贴文字翻译。
