We report the discovery of 8800 new spectroscopically confirmed white dwarfs or subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtained Teff, log g and mass for most stars, and estimated the calcium abundances for DZs. We found 2 new Doxygen, 81 DQs, 187 DO/PG1159s, 228 DCs, 185 DAHs, 371 DZs, 418 DBs, 920 subdwarfs and 6534 new DAs.
