• desitarget.cuts now always uses DR4-style column names and formats
• new 60-bit TARGETID schema that incorporates RELEASE column from imaging surveys
• desitarget.brightstar builds masks on DR4-style data
• HEALPix pixel number (current nside=64) added to output target files
• select_targets passes around information related to HEALPix
• column PHOTSYS added to output files, recording North or South for the photometric system
