We present an upgrade of the OGLE Collection of RR Lyrae stars in theGalactic bulge and disk. The size of our sample has been doubled and reached 78350 RR Lyr variables, of which 56 508 are fundamental-mode pulsators (RRabstars), 21 321 pulsate solely in the first-overtone (RRc stars), 458 areclassical double-mode pulsators (RRd stars), and 63 are anomalous RRd variables(including five triple-mode pulsators). For all the newly identified RR Lyrstars, we publish time-series photometry obtained during the OGLE GalaxyVariability Survey.  We present the spatial distribution of RR Lyr stars on the sky, provide alist of globular clusters hosting RR Lyr variables, and discuss the Petersendiagram for multimode pulsators. We find new RRd stars belonging to a compactgroup in the Petersen diagram (with period ratios P_1O/P_F = 0.74 andfundamental-mode periods P_F = 0.44 d) and we show that their spatialdistribution is roughly spherically symmetrical around the Milky Way center.
