Godot's upcoming 4.3 release introduces the Parallax2D node, an improved replacement for ParallaxBackground and ParallaxLayer. The change was made to address issues and introduce new features to the parallax system. Users can convert their current nodes to Parallax2D, which offers a simplified workflow, camera rotation compatibility, support for CanvasGroup and BackBufferCopy, zooming with a Camera2D, autoscroll, improved documentation, and performance improvements. The new node is now compatible with BackBufferCopy and CanvasGroup and allows for rotating the camera without breaking the parallax effect.
