common error messages to port old resources

i was trying to port several old resources.

and all of them having these errors:

Quote:
"error C3861: 'isLastState': identifier not found
error C2039: 'isObjectRendered' : is not a member of 'SceneRenderState'
class "SceneRenderState" has no member "isObjectRendered" "

i belief all this errors was for changing the name of class SceneState to "class SceneRenderState".
+sceneGraph folder was renamed to scene.

question is where i can find record of this changes?
and can someone give me proper replacement of these function:

isLastState()
isObjectRendered()
