Primary modifications: In August, a problem with the GMOS South detectors resulted in a slight changes in the gain values. The PIs of the affected programs were notified and given a special file with the correct values to be used with the Gemini IRAF software. This patch release includes the new and the old values, with full support for automatic selection of the correct gain values based on the date at which the data were obtained. Also include in this release: - a fix to the IFU 1-slit mode support in GFDISPLAY. - improvements to the GSCUT usage and error messages. - new noise values for NIRI. - a fix to NSMDFHELPER to remove a 1-pixel difference between the cut coordinates obtained on Solaris versus Linux. - an update to the nsappwave.fits database for Michelle lowQ, T-ReCS low10, and T-ReCS low20 modes.
