One Copyright Update to rule them all As many open source projects have started doing it, we're removing the current year from the copyright notice, so that we don't need to bump it every year. It seems like only the first year of publication is technically relevant for copyright notices, and even that seems to be something that many companies stopped listing altogether (in a version controlled codebase, the commits are a much better source of date of publication than a hardcoded copyright statement). We also now list Godot Engine contributors first as we're collectively the current maintainers of the project, and we clarify that the "exclusive" copyright of the co-founders covers the timespan before opensourcing (their further contributions are included as part of Godot Engine contributors). Also fixed "cf." Frenchism - it's meant as "refer to / see".

Add AnimationTree Advance Expressions Allows specifying an expression as a condition for state machine transitions. This gives much greater flexibility for creating complex state machines. By directly interfacing with the script code, it is possible to create complex animation advance condition for switching between states. Ensure assigning AnimationTreeStateMachineTransition base expression node in editor is relative to current AnimationTree node. Allow setting an expression base node on the AnimationTree itself.

Rework StateMachine and nested StateMachine process Breaking compatibility: If a StateMachineTransition is connected to a nested StateMachine prior to this, it is removed. Also, there was a feature to connect another StateMachine as the End of a StateMachine, which is also removed to avoid reference confusion. It was like a GoTo Statement, also further passing the same reference to the blending process, causing the blending calculation to break or causing some StateMachines to not work.

Replace most uses of Map by HashMap * Map is unnecessary and inefficient in almost every case. * Replaced by the new HashMap. * Renamed Map to RBMap and Set to RBSet for cases that still make sense (order matters) but use is discouraged. There were very few cases where replacing by HashMap was undesired because keeping the key order was intended. I tried to keep those (as RBMap) as much as possible, but might have missed some. Review appreciated!

Improvements of state machine - Open the menu to add new animation nodes by dragging the transitions to empty areas and automatically connecting them. - Adds box selection to the state machine. - Add feature to group/ungroup selected nodes in a "sub" state machine. - Add start/end node by default. In addition, add new color to these nodes to differentiate then. - Add tooltip for transitions to show the connection "from -> to". - Add new "type" of transition line when multiple transitions are grouped. - Add popup to connect nodes in sub state machine. - Add dialog to select which nodes can be deleted when they are grouped. - Add classes: AnimationNodeStartState AnimationNodeEndState EditorAnimationMultiTransitionEdit - Implements disabled transition API Changes: - Now it's posible to add transitions between state machines, `AnimationNodeStateMachine::add_transition` will works with relative path, this means you can use it like this `add_transition("Idle", "Walk", tr)` or `add_transition("Idle", "StateMachine/Shoot)`.

Rework StateMachine and nested StateMachine process Breaking compatibility: If a StateMachineTransition is connected to a nested StateMachine prior to this, it is removed. Also, there was a feature to connect another StateMachine as the End of a StateMachine, which is also removed to avoid reference confusion. It was like a GoTo Statement, also further passing the same reference to the blending process, causing the blending calculation to break or causing some StateMachines to not work.

Add ValidatedCall to MethodBind * This should optimize GDScript function calling _enormously_. * It also should simplify the GDScript VM considerably. NOTE: GDExtension calling performance has most likely been affected until going via ptrcall is fixed.
