         * Version 0.8.0 released
         ========================
  
         Clean-up public interface
 	Adapt to GammaLib 0.9.0 interface
+        Introduce ctool base class
         ctbin now always merges event lists into a single counts cube
         ctmodel now always creates a single model cube
         Add ctexpcube tool (generates exposure cube)
