GoJS version 1.6 brings several new features and samples. Here are some highlights:
- Z-ordering within Layers by setting or binding the new Part.zOrder property.
- Animations for tree and Group collapse, and animation of Diagram.position with CommandHandler.scrollToPart.
- Links can now have automatically determined keys if you set the GraphLinksModel.linkKeyProperty.
- You can now send and receive incremental changes to a database instead of sending the whole model, with Model.toIncrementalJson and Model.applyIncrementalJson.
- Tooltips are now shown on touch devices when the user clicks on an object with a GraphObject.toolTip or in the diagram background when Diagram.toolTip is an Adornment.
