- 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

- 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()

- Added ability to describe override table for linked state tree references
- This allows to override parts of the tree e.g. based on character type
- Fixed visibility of the State parameter button when in fixed mode

- 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

- Implies that parameters are only set once at start
- Allows parameters to be safely mutated if needed, e.g. via property references
[CL 30765232 by mikko mononen in ue5-main branch]
- Added FStateTreePropertyRef which allows to get pointer to bindable output properties in the StateTree
- This will eventually supercede FStateTreeStructRef
[CL 30563615 by mikko mononen in ue5-main branch]
- During state selection keep track if the current state we're expanding is part of the active states, if not prevent access to instance data

- Added LinkedAsset State Tree State Type
- Allow to pick nested tree asset on LinkedAsset states
- Changed how linked state params are accessed using ParentFrame
- Added temporary instance data
- Temporaries are kept around until state selection
- Create temp instance data during state selection for state parameters (allows to create enter conditions based on subtree state params)
- Instantiate and Start linked State Trees global tasks and evaluators during state selection
- Matching temporary instances created during state selection are moved to instance data on state change (rest are discarded)
- Per node instance data is looked up just once, and FStateTreeExecutionContext::GetInstanceData() only serves the specific instance data.

- Remove DataView concept
- Added FStateTreeExecutionFrame, which defines an active branch of a specific state tree that is running
- Added FStateTreeDataHandle, which allows frame relative access of instance data (replaces the DataViews)
- Changed linked states to spawn new frames (will later extend to handle linked trees on other assets)
- Bumped StateTree data version number, requires recomplation of StateTrees

Added "Next Selectable State" transition option which is similar to "Next State" but the difference is that if the next state fails to be selected (i.e. enter condition failed), then instead of going back up the hierarchy, it will try to select the next sibling until it finds one that is selectable or if it reached the end of the sibling list.
