 Version 0.11.7 (still in progress)
+
+- Fixed: Security Problem found by Stefan Cornelius.
+  For more information look here:
+  https://lists.uni-koeln.de/pipermail/sec-info/Week-of-Mon-20060313/006561.html
+    
+- Added: "more random" by Patrik Nilsson:
+  This map type is just a hacked version of "autogenerated",
+  and is as the name tells more random. Since both block, 
+  rock and nothing are placed randomly inside the border.
+
 - Fixed: High CPU usage in menus.
   This fix was made by Chris E..
