A few issues have been identified in the last RC, which should now be fixed with the help of feedback I got from users. In a nutshell:
* Fixed a critical error which prevented dispcalGUI from launching under Mac OS X 10.6 * Fixed a critical error in certain situations related to source profile under advanced/gamut mapping options * Fixed issues with correctly addressing the selected display under multi-display Linux setups * Added support for "very low" calibration quality http://dispcalgui.hoech.net Enjoy, Florian Höch
