In data binding scenarios these propeties are not updated automatically. Currently if you want to bind the StartPoint and EndPoint properties of the RadDiagramConnection you will have to update new position of the connection manually. This can be done in the PropertyChanged event of the connection. In the Handler you can cast your connection to IConnection and call the Update() method, if the e.PropertyName holds the property that you change.

Will be available in Q1 2015 Release.

OrgTreeRouter holds references to RadDiagramConnections which are not removed from memory.

If you manually remove a connection from a container (Source and Target are still in the container) and then drag this container in another one an exception will be thrown.

The fix is available in LIB Version 2014.3.1326.

When using SettingsPane on connection, the source and target cap types combos can be misaligned. For example when source is None and target is arrow 1.

The RadDiagramContainerShape size expands when a connection is added in its Items and then a connection point is added with Ctrl+Click.

The fix is available in LIB Version 2014.3.1312.

Setting IsConnectorsManipulationEnabled on a shape doesn't hide/show the Connectors immediately - you have to force a VisualState update. 

The fix is available in LIB Version 2014.3.1312.

When a RadDiagramItem is deserialized, some of its properties receive local values. This is why if you have applied style setters on these properties, the value applied by the style setter is no longer used.

Add some connection points to polyline connection. Move them. Then Select all with Ctrl + A. You will notice the Blue multiselection geometry is not with the correct geometry - it should be over the connection but it is not.

Fix is available in LIB Version 2014.3.1208.

In ConnectionDeserialized event the ConnectionSerializationRoutedEventArgs must contain the connection.
This must be just like shape is in the args of the ShapeDeserialized event.

In some cases when there are no crossings, empty spaces can be observed on the connections.

The fix will be available with Q1 2015 Release.

Connection Bridges Greatly Degrade Performance. Iven if there are no crossings, performance is very slow.
 In some scenarios empty spaces on the connections are observed even if there are no crossings.

The fix will be available with Q1 2015 Release.

ConnectionManipulationCompleted event does not fire when a shape is rotated more than 45 degrees and custom connector is used.
