### 3.箭头改进，箭头按照连线的实际角度显示（即0-360度），还支持自定义的箭头path。
### 4.新增快捷键自定义扩展，用户可根据自己的习惯定义快捷键。
### 5.封装了一个标准的工作流控件FlowchartEditor，具体使用可以参照开源权限管理框架种的用法： https://gitee.com/akwkevin/aistudio.-wpf.-aclient
nuget地址：![输入图片说明](nuget.png)
### 6.连接上添加动画：路径动画效果和线条流动效果。
### 7.改变结构，使用户更容易自定义自己的样式，覆盖系统默认样式。
### 8.从Blazor.Diagrams种引入PortlessLinks（直接连接两个node，不需要port），自动连接节点Snapping，按距离最近连接ReconnectLinksToClosestPorts
