+当前版本：`0.8.0`

 `0.7.0` 新增实时术语表能力：GPT 重翻会从配置的 `mingcibiao.json` 实时读取命中术语并写入提示词；网页中可查看当前术语表路径、搜索术语，新增、修改、删除条目并保存，保存后的术语会立即用于下一次重翻。
 
+`0.8.0` 新增阅读位置恢复：阅读器会自动记录当前章节/part/插图、当前可见段落和滚动位置；重新打开服务、刷新页面或切回已有会话时，会回到上次阅读的位置。

 ## 独立安装
 
 这个审校器现在可以脱离 Codex 使用，只需要 Python 和浏览器。把 `tools/epub_review_editor` 目录复制到其他电脑或服务器后，在该目录里安装依赖：

 ## 能做什么
 
 - 阅读模式下按章节连续阅读日文原文与中文译文，不需要逐句点击。
+- 每个审校会话会自动保存上次阅读位置，下次打开会回到上次所在章节、part、插图或段落附近。
 - 左侧目录和检索默认隐藏，通过顶部“目录”“检索”两个按钮分别打开，不会把两种入口混在同一个常驻侧栏里。
 - 目录优先按 EPUB 内部目录页或 nav/toc 组织章节；章节下显示内部 `part0000` 形式的 part 与次级插图条目，可展开/收起，点击 part 后只看该 part，点击章节则按原 spine 顺序连续阅读正文和插图。
 - 插图页会作为所属章节的次级条目出现在目录里，点击后可在阅读模式中直接查看原 EPUB 图片；点击目录项不会自动隐藏左侧侧栏。
