 Version 2.0.2 (in progress)
 ===========================
 
+2010-12-14: wsfulton
+            Fix $basemangle expansion in array typemaps. For example if type is int *[3],
+            $basemangle expands to _p_int.
+
 2010-12-07: iant
 	    Check that we are using a sufficiently new version of the
 	    6g or 8g Go compiler during configure time. If not, disable Go.
