+	  - Add the -proxydel/-noproxydel options to enable/disable
+	    the generation of proxy/shadow __del__ methods, even
+	    when now are redundant, since they are empty.
+	    However, old interfaces could relay in calling them.
+
+	    The default behavior is to generate the __del__ methods
+	    as in 1.3.27 or older swig versions.
+
+	    The option -O now also implies -noproxydel.
