+            [Go] Removed golang stringing for signed/unsigned char
+
+            Changed default handling of signed char* and unsigned char* to be
+            opaque pointers rather than strings, similarly to how other
+            languages work.
+
+            Any existing code relying on treating signed char* or unsigned
+            char* as a string can restore the old behavior with typemaps.i by
+            using %apply to copy the [unchanged] char* behavior.
+
+            *** POTENTIAL INCOMPATIBILITY ***
