Popis:	We investigate the median flattening of galaxies at $0.210^{11}M_{\odot}$ are rounder than those at lower masses, consistent with the hypothesis that they have grown significantly through dry merging. The massive quiescent galaxies at higher redshift become flatter, and are as flat as star forming massive galaxies at $2.5 Comment: 13 pages, 11 figures, accepted to ApJ
