Version 1.5.1 of MindFusion.Diagramming for Android contains the following new features and improvements:

State management
DiagramView now handles Android lifecycle events to automatically preserve its scroll position, zoom level and diagram's contents. You no longer have to implement Activity's onSaveInstanceState and onRestoreInstanceState to manually manage state, unless you prefer rebuilding the diagram from already saved data. To disable built-in state management, set android:saveEnabled="false" in DiagramView's definition in layout file, or call respective setter from code.

Miscellaneous
~ Diagram.createImage returns a Bitmap representing the diagram's contents;
~ the HtmlBuilder class creates an HTML image map whose areas link to items' HyperLink locations, letting users click on individual items in exported diagram images;
~ the ShowGrid and GridStyle properties implemented in Diagram class let you draw alignment grid, either as points or lines;
