Does SKShapeNode save memory?

Question

There is a lot of information about all the problems with SKShapeNode in iOS 7.

Memory leak in Sprite Kit application

Have all problems been resolved in iOS 8? There were no problem reports in August 2014, but I wanted to make sure before I dedicated SKShapeNode.

Update:

According to LearnCocos2D, you probably shouldn't use SKShapeNode for serious games. However, based on what I read and from my (brief) experience, SKShapeNode will not cause headaches during everyday use. I am inclined to assume that this is true, unless someone has the information specified otherwise?
