+
+### 0 . 2 . 1
++ 修复试卷模式下，生成 pdf 后的书签会显示题目大标题的问题，确保只显示章节
++ 西文字体新增 Times New Roman 字体风格；前提是安装了 STIX 2 系列字体。如未安装则默认使用 New Computer Modern Math
++ 优化代码
+
+### 0 . 2 . 0
++ 添加 `cover` 方法；该方法可以生成一个封面
++ 添加 `underdot` 方法；在一些场景下，可以为文本添加着重号
+
+### 0 . 1 . 9

+### 0 . 1 . 8
++ 为 `mode`  添加新值 `SOLUTION`，当答案解析独立于试题存在时，使用此值可快速统一格式
++ 优化 `choices` 方法；将其参数 `column` 更名为 `columns`，做到和官方的 `columns` 参数一致
++ 废弃 `inline-square` 方法，推荐使用内置的 `table` 方法
++ 修复 `color-box` 方法报错的 bug
