  The Sloan Digital Sky Survey has allowed us to increase the number of known
white dwarfs by a factor of five and consequently the number of known pulsating
white dwarfs also by a factor of five. It has also led to the discovery of new
types of variable white dwarfs, as the variable hot DQs, and the pulsating
Extremely Low Mass white dwarfs. With the Kepler Mission, it has been possible
to discover new phenomena, the outbursts present in a few pulsating white
dwarfs.
