Dose replaceScene in cocos2d-x clean up memory, sprites , etc ?

Hi all been wonderful changing to cocos2dx. I have been using coco2d and when I replace the scene memory, sprites, arrays, box2d, etc was automatically cleaned for me i did not have to free any memory or sprites or any thing, I was just wondering if i get the same result in cocos2d-x if i call replace scene if I have to do the housekeeping and free all the memory myself or do i still get all that for free in 2d-x.

Only for CCObjects. Any other objects you allocated yourself, you still have to clean them up manually.
