Node editor , compositing nodes autorender materials not updating

Hello

The node editor, compositing nodes autorender won’t update materials ,the world color settings and texture settings

unless i move objects or press F12 Is this a bug or feature that is missing?

Update:

Its a feature that is not implented yet

This is useful basically the idea is change materials,textures,world colors and its automatically updating the render,

rather than just pressing f12 or move objects to update the render
