- Fix `callable_mp` bindings to methods which used to have default
arguments passed to `bind_method`. We now have to re-specify them
manually when connecting.
- Re-add `GroupsEditor::update_tree` binding.
- Misc code quality changes along the way.
Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.
Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.
