In the time since the original QVS catalog release, the overlap between publicly available SDSS data and QVS data has increased by 8% in sky coverage and 16728 in number of matched objects. The astrometric matching and the treatment of SDSS masks have been refined for the updated catalog. We report on these improvements and present multiple bandpass light curves, global variability information, and matched SDSS photometry for 214941 QUEST1 objects. Description: QUEST1 constructed a 16-chip CCD camera to be used on the 1m Schmidt telescope at the Llano del Hato National Astronomical Observatory in Venezuela. Normally operated in the drift-scan mode, an equatorial scan will expose any point on the sky for 143s and result in limiting magnitudes of B=18.5, V=19.2, and R=19.5 at S/N=10. These data were collected between 1999 February and 2001 April. File Summary:
