SceneTree overrides the virtual `process` and `physics_process` methods
that it inherits from MainLoop. These methods return a boolean that
determines if the main loop should end.
The SceneTree was ignoring the returned boolean, so scripts inheriting
from SceneTree that override these methods and return true didn't exit
the main loop. Now the boolean is checked.
* Node processing works on the concept of process groups.
* A node group can be inherited, run on main thread, or a sub-thread.
* Groups can be ordered.
* Process priority is now present for physics.
This is the first steps towards implementing https://github.com/godotengine/godot-proposals/issues/6424.
No threading or thread guards exist yet in most of the scene code other than Node. That will have to be added later.
Provides an obvious way to unload the currently loaded scene (which is nowhere to be found in the docs).
The SceneTree.change_scene_to() method must now always provide a valid PackedScene.
Fixes#63565.
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".
This prevents the project setting from being located directly within
a root category, which is confusing from an UX perspective in the
project settings editor.
Control-nodes without a shortcut-context were missing a check if
the event was handled, so that a single shortcut-event was passed to
multiple Control-nodes.
Nodes may have been deleted by shortcuts. For example, when switching
scenes with `Ctrl` + `Tab` / `Ctrl` + `Shift` + `Tab`, some controls
will be deleted and recreated.
Before this change, the SceneTree had methods named “change_scene” and
“change_scene_to”. One of them accepted a String as a parameter and the
other accepted a PackedScene, but you couldn’t tell which one was which
just by looking at their names.
This change renames those two methods to “change_scene_to_file” and
“change_scene_to_packed”. These new names came from this suggestion [1].
These new names make the difference between the two methods more clear
and hint at the fact that there’s more than one change_scene method.

Fixes#27640.
