 # Changelog

+## 0.5.0
+
+This version is mainly about code level changes and optimization, with the core goal of improving rendering performance and reducing stuck issues.
+
+New: 1.Support custom expansion and collapse node icons and colors;
+
+optimization: 1.Optimize rendering logic, set the theme, move forward and backward, and other operations no longer require full rendering;
+
+     2.Optimize node drag logic, and fix the problem of being unable to drag between two nodes;
+
+     3.Collapse all nodes adds logic to return to the center point;
+
+     4.Fix the problem of nodes flying and scrambling caused by triggering rendering multiple times in a short time;
+
+     5.Optimize the experience of node editing;
+
+Fix: 1.Fix the issue where the setData method does not trigger history;
+
+modify: Starting from version 0.5.0, considering performance issues, the node activation state can only modify shape related styles:
+
+```js
+[
+  'fillColor',
+  'borderColor',
+  'borderWidth',
+  'borderDasharray',
+  'borderRadius'
+]
+```
+
+## 0.4.7
+
+optimization: 1.During rich text editing, when initially focusing, all are no longer selected by default; 2.When editing rich text, use the node fill color as the background color to avoid being invisible when the node color is white.  3.Node activation state switching no longer triggers history. 4.Triggering history multiple times in a short time will only add the last data. 5.Optimize the addition of historical records. When there is a rollback, delete the historical data after the current pointer when adding a new record again.
+
+New: 1.Support for importing and exporting Markdown format files. 2.Support for configuring initial text when inserting nodes. 3.Expand the commands for inserting and deleting nodes to support specifying nodes.
+
+## 0.4.6
+
+New: 1.Associated lines support adjusting control points.
+
+optimization: 1.When adding historical data, filter data that has not changed compared to the previous time.
+
+Fix: 1.Fixed a conflict between the direction keys and the navigation function of the direction keys during node editing. 2.Fixed the issue of node id loss when dragging a mobile node, which can cause associated lines to be lost.
+
 ## 0.4.5

 New: 1.Supports associative lines. 2.You can also drag the canvas by holding down the root node. 3. Hold down the ctrl key to adjust multiple selected nodes.

+
+## Methods
+
+### transformToMarkdown(data)
+
+- `data`: Mind map data can be obtained using the `mindMap.getData()` method.
+
+Convert mind map data into `Markdown` format data, and the returned data is a string.
+
+### transformMarkdownTo(mdContent)
+
+- `mdContent`: The `Markdown` data to convert, string type.
+
+Convert the `Markdown` string into node tree data and return a `Promise` instance. You can use the `mindMap.setData()` method to render the converted data onto the canvas.

 # Changelog

+## 0.5.0
+
+这个版本主要是代码层面的改动和优化，核心是为了提升渲染性能，减少卡顿问题。
+
+新增：1.支持自定义展开收起节点图标和颜色；
+
+优化：1.优化渲染逻辑，设置主题、前进回退等操作不再全量渲染；
+
+     2.优化节点拖拽逻辑，修复无法拖动到两个节点之间的问题；
+
+     3.收起全部节点操作增加回到中心点的逻辑；
+
+     4.修复短时间多次触发渲染造成节点乱飞和错乱的问题；
+
+     5.优化节点编辑的体验；
+
+修复：1.修复setData方法不触发历史记录的问题；
+
+修改：从0.5.0版本开始，考虑性能问题，节点激活状态只能修改形状相关的样式：
+
+```js
+[
+  'fillColor',
+  'borderColor',
+  'borderWidth',
+  'borderDasharray',
+  'borderRadius'
+]
+```
+
+## 0.4.7
+
+优化：1.富文本编辑时初始聚焦时不再默认全选；2.富文本编辑时使用节点填充色作为背景色，避免节点颜色为白色时看不见。 3.节点激活状态切换不再触发历史记录。 4.短时间多次触发历史记录，只会添加最后一次的数据。 5.优化历史记录添加，当有回退时，再次添加新记录时删除当前指针后面的历史数据。 
+
+新增：1.支持导入和导出Markdown格式文件。 2.支持配置插入节点时的初始文字。 3.扩展插入节点和删除节点的命令，支持指定节点。
+
+## 0.4.6
+
+新增：1.关联线支持调整控制点。
+
+优化：1.添加历史数据时过滤和上一次相比没有改变的数据。
+
+修复：1.修复节点编辑时方向键和方向键导航功能的冲突问题。 2.修复拖拽移动节点时节点id的丢失问题，这会导致关联线丢失。
+
 ## 0.4.5

 新增：1.支持关联线。 2.按住根节点也可以拖动画布。3.按住ctrl键可以调整多选节点。

+```
+
+## 方法
+
+### transformToMarkdown(data)
+
+- `data`：思维导图数据，可以通过`mindMap.getData()`方法获取。
+
+将思维导图数据转换成`Markdown`格式数据，返回的是字符串。
+
+### transformMarkdownTo(mdContent)
+
+- `mdContent`：要转换的`Markdown`数据，字符串类型。
+
+将`Markdown`字符串转换成节点树数据，返回一个`Promise`实例。可以使用`mindMap.setData()`方法将转换后的数据渲染到画布上。
