5th dnd – Which playable races were cut between 4th and 5th?

I'm just starting with D & D, and although I have not played yet, I'm in love with everything in the PHB. But I'm a fan of self-torture / more content, and I was wondering what had been forgotten when 5th was out in terms of playable races.

What playable races were cut in the 4th to 5th transition?
