+KGamma 0.9.9:
+
+* Add multi-head support (fix bug #321)
+* Add screen selector
+* Add screen synchronisation
+* Change kgammarc format (old user settings are lost)
+* Fix a localisation bug in class GammaCtrl 
+* Add class XF86ConfigPath
+* Add Dutch translation (by Rinse de Vries) 
+* Add Czech translation (by Daniel Prynych)
+
+KGamma 0.9.2:
+
+* Fix compile errors with configure option --enable-final (again)
+* Cancel the split into two parts (admin and user mode), add a
+  checkbox to choose where to store the settings (user config file 
+  or XF86Config)
+
+KGamma 0.9.1:
+
+* Fix compile errors with configure option --enable-final
+* French and spanish translation update
+* Install script update
+
+KGamma 0.9:
+
+* Add admin mode (in this mode, gamma settings are stored to XF86Config)
+* Add spec file for RPM based distributions (Dominik Seichter)
+* Remove class RGBCtrl, handle the widgets in main widget
+* Add check for XFree86-VidModeExtension to configure.in.in
+* Add wrapper class XVidExtWrap to access XFree86-VidModeExtension directly, 
+  KGamma no longer needs xgamma as a backend
+
+KGamma 0.2.3:
+
+* Minor install script changes, should compile with KDE2 and KDE3 now 
+
+KGamma 0.2.2:
+
+* Ported to KDE3 
+
+KGamma 0.2.1:
+
+* Code clean up
+* Converted all strings to QString to avoid copying between QString and char*
