3.0.1

Added

• Route property to BaseLinkModel to hold the result of the executed router

Fixed

• Constraints not checked when using RemoveControl (thanks to @K0369)

3.0.0

Finally, the new documentation website is here!
Please don't hesitate to create issues for any problems or improvements.
PS: I suck at design.

Added

• AddLabel method to links to easily create LinkLabelModel
• AddVertex method to links to easily create LinkVertexModel
• ControlledSize property to nodes. If true, the node will not be registered in the ResizeObserver (saves a JS call).
• autoSize argument to SvgGroupModel constructor

Changed

• Renamed Point.Substract to Subtract (duh)
• Avoid rendering link selection helper on dragged link

Fixed

• SmoothPathGenerator not working with LinkAnchor
• Mouse overlapping dragged link
• Useless Console Logs from GroupModel are now removed
• JS exception in (un)oberve methods when the element doesn't exist anymore

Check out the other beta version for a complete CHANGELOG !

3.0.0 beta 7

Fix a dumb issue by me regarding ordering

3.0.0 beta 6

All NuGet packages have been updated.

Added

• Style parameter to PortRenderer
• TargetAttached to links, which triggers when a dragged link attaches to a target
  • If port snapping is enabled, it will trigger only once when you let go of the mouse
• SuspendSorting to Diagram in order to suspend sorting models in each OrderChanged
  • If you know what you're doing, you could save some processing and avoid sorting everytime
• RefreshOrders to be called after unsuspending sorting in order to sort the models again and refresh the diagram

Changed

• BaseLayer.Add now returns the specific type given to it in argument
• [BREAKING] CSS classes are now prefixed with diagram- to avoid clashes with other libraries
  • diagram-group, diagram-node, diagram-link, diagram-port, diagram-link-label, diagram-link-vertex, diagram-control

Fixed

• Portless links in children not refreshing when moving the parent group
• Link's GetBounds not returning a valid box
• Port snapping choosing the first port in radius rather than the closest one
• Remove Console.WriteLine from KeyboardShortcutsBehavior
• Diagram overwriting Order when it's not zero (zero being the default int value, which we now consider as not set)

3.0.0 beta 5

Added

• AdditionalSvg option to DiagramCanvas in order to render any extra SVG content you want
• AdditionalHtml option to DiagramCanvas in order to render any extra HTML content you want
• DistanceTo overload method to Point that takes x and y
• MoveAlongLine method to Point
• FullPath to PathGeneratorResult to represent the full path without cuts
• Fallback router to Orthogonal router
• Margin options to OrthogonalRouter
• radius option to StraightPathGenerator in order to generate rounded bends
• Support for custom vertices
• AutoSize option to groups to control whether moving children resizes the group

Changed

• All routers are now classes instead of functions, they inherit from the new abstract class Router
• All path generators are now classes instead of functions, they inherit from the new abstract class PathGenerator
• Optimize Orthogonal router by using custom A* (x5 improvement)

Removed

• Router delegate
• PathGenerator delegate

3.0.0 beta 4

Added

• Initial version of Ordering!
  • Nodes, groups and links can now be ordered using the new Order property or SendToFront/Back methods
  • Diagram.OrderedSelectables returns the ordered selectables/models
  • DiagramCanvas now uses this new property to render everything
• GridSnapToCenter option in order to snap nodes from their center instead of their top/left position (thanks to @Jeremy Vance)
• More unit tests

Changed

• Groups is not a list of groups anymore, but a layer instead (just like Nodes and Links)

Fixed

• Deleting a group doesn't delete links attached to it
• Deleting a group inside of a group doesn't refresh the parent group
• Links not refreshing when a group's dimensions are updated directly (e.g. deleting a child)
• Layers causing more refreshes than intended

Removed

• All group-related methods and events from Diagram, please use the new layer from now on

3.0.0-beta.3

Added

• Support for LinkFactory to return null in order to not create an ongoing link
• Support for free links (no source/target required)
• PositionAnchor which reprensents a simple plain position (mutable)
• ArrowHeadControl to control a link's Source/Target on the fly
• attached css class to attached links

Changed

• Replace OngoingPosition with the new PositionAnchor
  • BaseLinkModel.Target will never be null anymore. An ongoing link will have a position anchor as the target
• Links.Factory signature now takes the diagram, source (model) and the target anchor
• Move DynamicAnchor back to Anchors namespace and seal all Anchor classes

Fixed

• Links attached to links not refreshing when the others are
• LinkPathPositionProvider not working with maxlength ratios
• Deleting a link not deleting the links attached to it

Removed

• PositionProvider argument from ExecutableControl for more freedom
• Id and Refresh from ILinkable
• Unused Offset from Anchor and make Model nullable

3.0.0 beta 2

Added

• Moved event to Movables
• Visible property and VisbilityChanged event to models
• Options.Virtualization (of type [Diagram]VirtualizationOptions) for virtualization options
• PointerEnter/Leave events for groups as well
• Experimental Link to Link (using LinkAnchor)

Changed

• Rename RegisterModelComponent to RegisterComponent
• Rename GetComponentForModel to GetComponent
• Virtualization is now handled by a behavior instead of NodeRender
  • This means that it works for almost all models (nodes, groups and links)
• Render link labels without foreignObject in widget nor MarkupString (Thank you .NET 6)
• Custom link labels only need to contain relevant content, they don't need to handle positioning anymore

Removed

• EnableVirtualization option (see added alternative)
