- When transitioning to a subtree directly, self host the parameters
- Made transitioning to a subtree directly a warning, may make it an error in future versions

[CL 32969399 by mikko mononen in ue5-main branch]
- 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()

[CL 32744822 by bob tellez in ue5-main branch]
- 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

[CL 32082269 by mikko mononen in ue5-main branch]
- 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]
- Allow each state to have parameters (not super useful yet)
- Made property bindings for parameters to retain binding when a param is renamed (keeps track of the property bag ID)
- Fixed access of temporary instance data with EStateTreeDataSourceType::StateParameterData
- Added comments for UStateTreeState properties
- Changed property order of UStateTreeState so that display data comes first, then state settings, and finally parameters
- Fixed FStateTreeStateParametersInstanceDataDetails to allow property editing and value binding at the same time
#rb Mieszko.Zielinski
[CL 30112368 by mikko mononen in ue5-main branch]
- 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.

[CL 30012308 by mikko mononen in ue5-main branch]
- 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.
