The new gTLD landscape is still evolving quite smoothly. The 20 top new gTLD are more or less the same since 6 months.
In February, there has been one newcomer in the top 20 : .rocks. All the others are the same.
Yet, with Google spending 25 million USD on .app, and other potentially very popular strings coming, changes may come in the next months !

xyz is still number 1, then xn-ses554g and club, trusting the podium since a few months..
