 # Changelog
 
+## 0.5.11
+
+New: Supports associative text editing.
+
+optimization: Optimizing theme configuration updates, changing configurations that do not involve node size does not trigger node recalculation.
+
+## 0.5.10
+
+New: Optimize node reuse logic using LRU caching algorithm.
+
+## 0.5.10-fix.1
+
+Fix: Fix the issue of import errors.
+
+## 0.5.10-fix.2
+
+Fix: Fixed the issue of switching themes and importing data without triggering data changes in rich text mode.
+
+New: Add three new themes.
+
+## 0.5.9
+
+Change: Unified export method format, using `FileReader` instead of `URL.createObjectURL` to convert `blob` data.
+
+## 0.5.8
+
+optimization: 1.The position setting is not triggered when the node position does not change. 2.The unfolding and folding status does not change and does not trigger button updates.
+
+New: 1.The default setting is to move the mouse over the node to display the expand and collapse buttons. 2.Support the list of icons that can be inserted into extended nodes.
+
 ## 0.5.7
 
 Breaking change：In rich text mode, exporting png has been changed to using html2canvas to convert the entire svg, greatly improving the export speed. However, html2canvas has a bug where the text color inline with the dom node in the foreignObject element cannot be recognized. Therefore, the text color of the exported node is fixed. However, compared to the previously unavailable state of the export, it can at least be exported quickly and smoothly.

 In summary, in open-source mind maps, it is difficult to find a better choice than `simple-mind-map`. Of course, `simple-mind-map` is far from being the best, and it also has many shortcomings, as you saw in the previous [special note]. However, `simple-mind-map` has always been in a fast iteration process, and we welcome you to join and improve it together.

+## 0.5.10-fix.2
+
+修复：修复富文本模式下，切换主题、导入数据后没有触发数据改变的问题。
+
+新增：新增三种主题。
+
+## 0.5.9
+
+修改：统一导出方法的格式，使用`FileReader`代替`URL.createObjectURL`转换`blob`数据。
+
+## 0.5.8
+
+优化：1.节点位置没有变化不触发位置设置。 2.展开收起状态没有变化不触发按钮更新。
+
+新增：1.默认改为鼠标移上节点才显示展开收起按钮。 2.支持扩展节点可插入的图标列表。

 ## 0.5.7
 
 破坏性更新：富文本模式下导出png改为使用html2canvas转换整个svg，大幅提高导出速度，不过html2canvas存在一个bug，foreignObject元素中的dom节点内联的文字颜色无法识别，所以导出节点的文字颜色是固定的，不过相对于之前的导出基本不可用状态，目前至少能快速顺利的导出。

+
+你可以通过如下方式获取：
+
+```js

+```
+
+如果你使用的是`umd`格式的文件，可以通过如下方式获取（v0.5.8+）：

+  }
+]
+```
+
+你可以通过UI界面展示出来，要给一个节点设置图标，可以使用`node.setIcon([])`方法，要获取节点当前的图标，可以使用`node.getData('icon')`方法。
+
+一个图标由`type_name`构成，比如前面的图标要插入节点，那么图标的值为`priority_1`。
+
+通常一个分组的图标只允许插入一个，所以存在一个替换的逻辑，完整示例如下：

+
+```js
+new MindMap({
+  // ...
+  iconList: [
+    {
+      name: '',// 分组名称
+      type: '',// 分组的值
+      list: [// 分组下的图标列表

+          icon:''// 图标，可以传svg或图片
+        }
+      ]
+    }
+  ]
+})
+```
+
+然后和插入内置图标一样，通过`setIcon`方法插入图标的`key`即可。
