             [Python] Fix #294 #296 - Regression introduced in SWIG-3.0.3 when
-            wrapping functions with default arguments. Now any method with default
-            arguments obtains the default arguments from C++ instead of generating
-            Python code with the default arguments.
-
-            The "python:defaultargs" feature has been introduced for users to
-            optionally generate Python methods with the default arguments instead
-            the default *args.
+            wrapping functions with default arguments. Invalid or missing default
+            arguments were sometimes being generated into the python layer.
