+> 一个简单&强大的Web思维导图
 
-Demo：[https://wanglin2.github.io/mind-map/](https://wanglin2.github.io/mind-map/)
+本项目包含两部分：
 
-文档：[https://wanglin2.github.io/mind-map/#/doc/zh/](https://wanglin2.github.io/mind-map/#/doc/zh/)
+1.一个js思维导图库，不依赖任何框架，你可以使用它来快速完成Web思维导图产品的开发。
+
+开发文档：[https://wanglin2.github.io/mind-map/#/doc/zh/](https://wanglin2.github.io/mind-map/#/doc/zh/)
+
+2.一个Web思维导图，基于思维导图库、Vue2.x、ElementUI开发，可以操作电脑本地文件，所以你可以直接把它当做一个在线版思维导图应用使用，如果觉得github的响应速度慢，你也可以部署到你的服务器上。

 # Changelog
 
+## 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.
+
+optimization: Optimize the rich text node editing experience.
+
+New: In rich text mode, importing data, initializing data, and switching theme scene node styles support following theme changes.
+
+## 0.5.6
+
+Fix: 1.Fix the issue of node position disorder during fast and multiple renderings in a short period of time. 2.Fix the issue of dragging the canvas while the node is being edited, causing the edit box and node to separate.
+
+New: 1.Add a maximum history limit.
+
+## 0.5.5-fix.1
+
+Fix: 1.Fix the issue where the edit box is also outside the canvas when editing nodes outside the canvas. 2.After modifying the structure, reset the transformation to prevent the problem of sudden position changes during the first drag after switching the structure during scaling.
+
+optimization: 1.When multiple nodes are selected, as long as there is a cross between the node and the selection area, it is considered selected.
+
+## 0.5.5-fix.2
+
+Fix: 1.Fix mini map error.
+
+## 0.5.5
+
+New: 1.Supports configuring the padding when exporting to PNG, SVG, or PDF. 2.Support the configuration of z-index for node text editing boxes and node comment floating layer elements. 3.Support clicking on areas outside the canvas to end node editing status.
+
+## 0.5.4
+
+New: 1.Add new themes. 2.Added timeline and fishbone structure.
+
+Fix: 1.Fix the conflict issue between node right-click and canvas right-click. 2.Fix the bug that the line segment is not hidden when dragging nodes such as organizational chart and directory organization chart.
+
+optimization: 1.Optimize the layout of organizational chart. 2.Optimize the layout of the directory organization chart.
+
+## 0.5.4-fix.1
+
+optimization: 1.Optimize fishbone layout.
+
+## 0.5.3
+
+Fix: 1.Fixed the issue of setting the text style when multiple nodes were selected in rich text mode, which would change the text of all selected nodes to the text of the last selected node.
+
+New: 1.Support setting the position of the initial central node.
+
+### 0.5.3-fix.1
+
+Fix: 1.Fix the issue where setting the position of the initial central node does not take effect.
+
+### 0.5.3-fix.2
+
+Fix: 1.Fix the issue of not displaying images in nodes when exporting as images.
+
+## 0.5.2
+
+Fix: 1.Remove `uid` from exported `JSON` data; 2.Clear the node cache pool when re rendering.
+
+## 0.5.1
+
+optimization: 1.Only respond to shortcut key events when the mouse is inside the canvas
+
+Fix: 1.Fix the issue of incorrect node position during fast operation
+
+## 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.

+## Why not？
+
+1.[Zhixi](https://www.zhixi.com/)
+
+Zhixi is a free mind mapping product that supports multi end synchronization. The UI design is beautiful and the features are complete, but it is not open source, so it can only be used as a user and cannot be used in your project.
+
+There are many other online mind mapping products similar to Zhixi, such as [GitMind](https://gitmind.cn/)、[MindLine](http://www.mindline.cn/)、[MinMeister](https://www.mindmeister.com/zh)、[Mubu](https://mubu.com/) and so on, There are many searches on search engines, but these products either require fees or are developed by small companies, and their stability and sustainability cannot be guaranteed. Of course, the most crucial thing is that they are not open-source.
+
+2.[kityminder-core](https://github.com/fex-team/kityminder-core)
+
+`kityminder-core` is an open source brain mapping tool developed by Baidu. It has powerful functions and good performance, but it is no longer maintained. Therefore, the code is relatively old, and the interface beauty is relatively ordinary. In addition, bugs can only be fixed by yourself, and the functions can only be developed by yourself. It has high requirements for front-end development capabilities.
+
+3.[jsmind](https://github.com/hizzgdev/jsmind)、[Mind-elixir](https://github.com/ssshooter/mind-elixir-core)、[my-mind](https://github.com/ondras/my-mind)、[blink-mind](https://github.com/awehook/blink-mind)、[remind](https://github.com/luvsic3/remind)、[vue3-mindmap](https://github.com/hellowuxin/vue3-mindmap)、[ZMindMap](https://github.com/zyascend/ZMindMap)...
+
+These open-source mind maps are also good, each with its own characteristics, but they also have certain drawbacks, such as stopping updates, average interface aesthetics, less functionality, relying on a certain framework, and so on.
+
+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.
+
+## Browser Compatibility
+
+We recommend using the latest version of the `Chrome` browser.
+
+Limited testing situation:
+
+Normal operation: `360` extreme speed browser（v13.5.2036.0）、`opera` browser（v71.0.3770.284）。
+
+Abnormal operation: `Firefox`（v98.0.2）, Node content cannot be displayed in rich text mode. If you want to support the `Firefox` browser, please use non rich text mode.
+
+Unsupported: `IE` browser.
