@@ -4,6 +4,10 @@ AS OF SVN REV. 5091, WE ARE NOW USING TRUNK.  ALL UNTESTED BUGFIXES/FEATURES GO
 IF YOU HAVE A WORKING AND TESTED BUGFIX PUT IT INTO STABLE AS WELL AS TRUNK.
 
 2006/04/06
+	* The IRC Bot is now able to check each users access level prefix
+	  in the channel (~/&/@/%/+), the IRC command @kami now requires the
+	  user to be at least channel operator(@). Now I need to make it store
+	  the users access level on every nick/mode change. [Zido]
 	* Changed the default of skill_add_range to 0, said value now disables
 	  skill-range checking when casting ends. [Skotlex]
 	* Corrected the Soul Drain formula, thanks to Haplo for pointing it out.
