Version 1.3.0 includes a number of bug fixes, and a couple of new features: Added option to dispcal and dispread that attempts to counteract instrument black drift and display white drift (-I option). Added option to dispcal to allow specifying a non 1931 2 degree observer if a spectrometer is being used. Added new utility ccmxmake, which makes Colorimeter Correction Matrices for a particular Colorimeter + Display combination, using a Spectrometer as a reference. The resulting .ccmx file can then be used with spotread/dispcal/dispread (-X option). Fixed bug in spotread's handling of emissive spectral measurements. Fixed bug in i1pro normal resolution wavelength calibration. Added support for HP DreamColor version of the i1 display. Fixed problem with ARGYLL_NOT_INTERACTIVE. Fixed bug in ColorMunki adaptive mode. See <http://www.argyllcms.com/> for the downloads. Graeme Gill.
