-      - Improved JTAC Performance - priority & targeting
+      - Allow minimum distance from friendly logistics to be set
-      - Added JTAC report for in view
-      - Added ability to set maximum group size that can be carried
-      - Added new sling load crates
-      - Fixed bug where crates and / or groups would disappear
-      - Fixed bug where count in zone wouldn't work for mission crates
-      - Delayed config of F10 menu and other scheduled functions so they can be overwritten by mission if a user wants
