NEW FEATURES

• Added multi-selection system. Customize the selection box brush in a Graph Customization asset.

• Pressing CTRL + A in a graph editor will select all the nodes.

• Added a grid cell system in the graph, dividing it into sections (cells) to improve efficiency of multi-selection.

• Added tooltips to default pin widgets that display the pin's description. If a connection preview is active, they indicate whether a connection can be made and provide the reason if it can't.

• Pins can now be replaced if the connection reason is suitable.

• Added GetPinValidityMessage static function that returns messages about the validity of a pin connection.

• Added UExecutionPinBase::GetFriendlyPinToolTipText function that shows user-friendly tooltips with details about the pin.

• Added UExecutionPinBase::IsReplaceable to check if a pin can be replaced.

• Added UGraphEditorBase::GetActiveGraphObject - UGraphEditorBase::IsGraphLoaded and UGraphEditorBase::ClearGraph functions.

• Added UOpenLogicTask::ExecuteAndCompleteTask and UOpenLogicTask::GetContext functions.

• Added a new event UNodeBase::OnNodeUnregistered.

• Added UNodeBase::SetNodePosition function.

• Added new static functions CreateRuntimeWorkerFromObject and CreateRuntimeWorkerFromStruct.

• Added the OnTaskNodePlacedInGraph event to UNodePaletteBase.

• Added CanConnectToMultiple variable to UOpenLogicProperty.

• Added "InPinWidget" as a bindable widget for execution pins. If valid, the UExecutionPinBase::GetGraphPosition will use this widget as a reference.

• Added UNodeBase->OnNodeDesiredSizeChanged event dispatcher.

IMPROVEMENTS

• The functions UNodeBase::AddToMovingNodes() and UNodeBase::RemoveFromMovingNodes() are now automatically managed by the selection system.

• Pin connections now automatically update when the desired size of a node changes.

• The desired size of default pins now affects the overall size of the node in the default node widget.

• You can now change the grid snap size through a Graph Customization asset.

• PinConnectionClass can now be changed directly in UNodeBase.

• Graph Editors now reload automatically when a Widget class is recompiled.

• The node palette now lists all tasks, even those which have the same name.

• The default graph editor Initialize function is now moved to C++ as UGraphEditorBase::InitializeGraphEditor.

• Improved UGraphEditorBase::LoadGraph function.

• UExecutionPinBase::CanConnectTo function now gives specific reasons why a connection can't be made.

• Replaced the default grid material with a native Slate-painted grid, similar to Blueprint, which can be customized in a Graph Customization asset.

• The payload editor will now be displayed within the node as a displayable widget. The widget container is no longer necessary.

• The payload editor now supports simultaneous task selection.

DEPRECATION

• Deprecated UOpenLogicTask->InputPinsCount and UOpenLogicTask->OutputPinsCount. Use getters instead.

• Deprecated UConnectionBase class.

• Deprecated UOpenLogicPayloadWidget class.

RENAME

• Renamed UOpenLogicTask::OnTaskBegin to OnTaskActivated.

• Renamed UOpenLogicTask::OnTaskEnd to OnTaskCompleted.

• Renamed UOpenLogicTask::OnEditorNodeInitialized to OnGraphNodeInitialized.

• Renamed UOpenLogicTask::OnEditorNodeSaved to OnGraphNodeSaved.
