 4. 新增`OpenXmlCompositeElement`复杂类型的节点类，提供各种操作的方法，大部分有子节点的类均继承于该类。如`RPr`会有`B I Sz`等子节点元素，而`B I`这类的元素是`<x />`的`OpenXmlSimpleType`类型的
 
 影响范围：列表暂无；具体可见对应类的`// simple_type property`下的属性
+
+## v3.0.0
+
+对`adapter`做了`break changes`的更新
+
+1. `unit`文件更名为`adapters`复数结尾，如`DocxMLAdapter` -> `DocxMLAdapters`
+2. 移除冗余的命名方式（移除每个类的`Adapter`后缀），`StylesAdapter` -> `Styles`
+
+```pascal
+// 弃用
+uses DocxMLAdapter;
+
+styles_adapter := DocxMLAdapter.StylesAdapter(styles);
+
+// 迁移
+uses DocxMLAdapters; // 复数s
+styles_adapter := DocxMLAdapters.Styles(styles); // 移除冗余
+```
