* For now, this is limited to instances inside custom objects. This will be made available in the future for all instances in scenes if this works well.
* New actions are available to save & load the game state, making Saving & Loading as easy as adding 1 action to your game!
* While it will work in most cases, it has a few limitations and hasn't been thoroughly tested on all types of objects/behaviors and games, so it is for the moment tagged as **Experimental** while we gather feedback and improve it
* Check out the wiki for more info: https://wiki.gdevelop.io/gdevelop5/all-features/save-state
* This allows playing around with instances directly on the canvas instead of relying on the actions to flip or change opacity and needing to start a preview
* An object changing layer during the game is now properly moved to the layer on the other players games
* Video object can be synced as well
* Pathfinding behavior is now properly synced, allowing a smooth prediction on other players games
* Spine object is now synced as well
- Custom objects like the 3D particle emitter can be used as any other 3D object
- with the same set of actions and conditions thanks to the 3D capability
- in the scene editor, their Z position and 3D rotations can be changed
- Fix child creation in `doStepPostEvent` function
* Actions, conditions and expressions related to opacity, size (width/height), scale, animations and other common features are now visible only once when you search for them in actions/conditions (instead of being shown once for every type of object supporting them). This reduces the risk of confusion for new or existing users, notably when multiple versions of the same action were returned by the search and was making it difficult to choose the proper one.
* Internally, this works thanks to default, built-in behaviors that are supported by the objects.
* This provides new 3D objects: 3D Box (perfect to create walls, floors, or billboards) and 3D Model (to import objects created in a 3D modeling app).
* 2D and 3D can be mixed in a same game. Each layer of a game can contain 2D objects, 3D objects or a mix of both.
* This allows to build 2D games, 2.5D games and full 3D games: platformers, racing games, FPS, hyper casual games. It's easy to start adding 3D objects to an existing 2D game.
* You can set up a light by adding an ambient light and/or directional light in the effects of a 3D layer. 3D objects can be configured to react to light or ignore it.
* In the future, support for 3D objects will be improved: light objects, animations, etc...
