00324b3fb2 UE State tree
- Added transition recording functionality to enable snapshots for state tree transitional events
- Primary use case is for keeping client-side state trees in sync with their server counterpart

08b5314641 [StateTreeDebugger] replaced WITH_STATETREE_DEBUGGER by WITH_STATETREE_TRACE and WITH_STATETREE_TRACE_DEBUGGER to allow different targets to use only one of the two functionalities. For example consoles can only output traces while Desktop targets can output traces and analyse them.

60131c19b5 [State Tree] StateTreeInstanceData RandomStream variable Initialization Fix/Improvement
- When duplicating the Component, RandomStream was always copied from the one on Component CDO and wasn't constructed with the current time as expected. We now initialize RandomStream at FStateTreeExecutionContext::Start(), where the InstanceData is going to persist till Stop().
- Moved RandomStream variable to FStateTreeExecutionState as it better reflects the window it persists now.
- Fixed non-deterministic default-constructed value of RandomStream variable in UStruct LogError by the above

2b93815d0a StateTree: Improved event handling
- Added support for shared event buffer, so that multiple instance data can use the same
- Added API to consume events
- Removed double buffering from events
- Treat TriggerTransitions() as event handler (events flushed after each call to the method)
- Event handlers (including tasks) are executed in priority order
- Transitions and event capturing states can consume events on successful selection
- Added API to tick a StateTree in two passes (update tasks and trigger transitions)
- Change parallel tree tasks to do the task update in Tick(), and event handling in TriggerTransitions()
- Small improvements to the ST debugger to display events
- NOTE: this is breaking change for implementations that has relied events emitted during tick to be available on next EnterState()

a82ca89e98 StateTree: Added support for event payload in transitions and event capture for states. (contributed) [take 2]
- Transitions can now be set up to require a specific payload type and/or a gameplay tag
- Required transition event payload is visible to property bindind for transition conditions
- States can require an event type as enter condition, the event is captured when state is selected
- Required state event payload is visible to binding for state enter conditions, tasks and transistions
