What Does Maker-Taker Mean?
Every trade occurs between two parties: the maker, whose order exists on the order book prior to the trade, and the taker, who places the order that matches (or "takes") the maker's order. Makers are so named because their orders make the liquidity in a market. Takers are the ones who remove this liquidity by matching makers' orders with their own.

The maker-taker model encourages market liquidity by rewarding the makers of that liquidity with a fee discount. It also results in a tighter market spread due to the increased incentive for makers to outbid each other. The higher fee that the taker pays is usually offset by the better prices this tighter spread provides.

What Are the New Fees?
