FlowChart.NET version 6.0.3 adds the following customer-requested features:

ContainerNode improvements
- child nodes are now drawn by their containers; when containers overlap, the children of a lower container cannot appear in front of the upper container anymore
- the ClipChildren property specifies whether to clip child items to container’s boundaries
- the ZIndex property no longer changes automatically when dropping nodes into a container
- the Visible property of child items no longer changes when folding or unfolding containers; this lets you keep invisible items inside containers
- when selection including a container and its child node is dropped into another container, the child node now remains in its original container

PdfExporter improvements
- improved handling of clip regions in custom drawing code
- PdfExporter now honors the target Rectangle property of linear gradients
- PDF shadings now include all colors from a ColorBlend
- more precise character widths set when text includes both eastern glyphs and Latin characters
- more precise widths set for Cyrillic characters

New events
- the SetSelfLoopShape event is raised when a link becomes a self-loop, giving you a chance to set a custom shape for the link
- QueryAlignTarget event is raised to determine if a node should be used as alignment guide target when AutoAlignNodes is enabled.

Miscellaneous
- NegatedX and NegatedY properties added to Ruler control
- CatchGdiPlusExceptions property now works for nodes too
- now HtmlBuilder can create areas for TreeViewNode items
- public Sort methods added to diagram item collection classes
