This is the first release for UE 5.7.

Flow Asset

• Added UFlowAsset::GatherNodesConnectedToAllInputs helper function. (contributed by Riot Games)

Flow Node

• Added UFlowNode_FormatText that formats text using input pins and FText formatting engine. (contributed by Riot Games)
• Changed the UFlowNode_Log to format text (a la UFlowNode_FormatText) to generate its logged output string. (contributed by Riot Games)
• Changed UFlowNode_Log to inherit from UFlowNode_DefineProperties, so that it can have input properties added on the instance. (contributed by Riot Games)
• Renamed UFlowNode_DefineProperties::OutputProperties to NamedProperties, so that it can be used as the super class for UFlowNode_FormatText. (contributed by Riot Games)
• Renamed FFlowNamedDataPinOutputPropertyCustomization, which is now also used for input pins. (contributed by Riot Games)
• Added enum-based constructors for FFlowDataPinResult structs. (contributed by Riot Games)
• Added FLOW_API to GetFlowPinType() functions to allow it being called from extension plugins. (contributed by Riot Games)
• Added GetRandomSeed() function to UFlowNode. The default version uses the hash from the node's GUID. This can be overridden in subclasses (which we do) to any implementation that suits the client code. (contributed by Riot Games)
• Added an IsFinishedState() classifier function for EFlowNodeState, to error-proof checking node state for "finished" states. (contributed by Riot Games)
• OnNodeDoubleClicked logic moved to the Graph Node itself, allowing for overriding the default logic.
• Updated the ForEachAddOn templates to support a parameter to control how the function should recurse into child addons (or not). (contributed by Riot Games)
• Fixed UFlowNode_ExecuteComponent to handle injected components correctly in validation. (contributed by Riot Games)
• Fixed UFlowNode_ExecuteComponent to conform to the new style of pin generation, now using ContextPins (the old method didn't work after a refactor with flow graph node reconstruction). (contributed by Riot Games)
• Updated UFlowNode_ExecuteComponent to allow the component to supply data pin output values. (contributed by Riot Games)
• Extracted UFlowNodeAddOn::FindOwningFlowNode() functionality into a function. (contributed by Riot Games)
• Fixed some Datapin result logic. (contributed by DemonViglu)

Misc

• Fixed an issue where breakpoint overlay brushes weren't showing properly due to deprecated code in 5.6. (contributed by Greggory Addison)
• Preventing a crash while using Ctrl + Shift + X shortcut of the BlueprintAssist plugin. (contributed by Numblaze)
• Non-unity build fixes. (contributed by bohdon)
