We have released version 3.3.2 of MindFusion JavaScript Diagram library. It contains the following new features and improvements:

Improved performance
Diagram rendering and user interactions are now faster. The control redraws the smallest possible area after diagram changes, and compresses refresh operations into a single batch when possible. Custom node classes that need to draw outside of their Bounds should override the getRepaintBounds method to specify the repaint area.

Miscellaneous

• The Border component draws frame lines around and background behind other components in CompositeNode templates.
  
• NodeListView now displays nodes' Tooltip texts when the mouse hovers over an item in the list view.
  
• Fix for FlowchartLayout creating node overlaps in some situations.
  

Distribution for the latest version can be downloaded here, or from the clients area on our site:

Updated scripts are also available as diagram-library NPM package.
    
Enjoy!
