+            #1340 Remove -cppcast and -nocppcast command line options (this was an option
+            available to the scripting language targets).
+
+            The -cppcast option is still turned on by default. The -nocppcast option
+            to turn off the use of c++ casts (const_cast, static_cast etc) has been
+            removed. However, defining SWIG_NO_CPLUSPLUS_CAST will still generate C casts
+            instead of C++ casts for C++ wrappers.

+            [Python] #1340 Remove -outputtuple and -nooutputtuple command line options.
+
+            Both the command line and %module options of the same name have been
+            removed. These were undocumented. The -outputtuple option returned a
+            Python tuple instead of a list, mostly typically in the OUTPUT
+            typemap implementations.
+
+            It unclear why a tuple instead of a list return type is needed and
+            hence this option has been removed as part of the simplification of
+            the SWIG Python command line options for SWIG 4.

+            [Python] #1340 Remove -noproxyimport command line option.
+
+            This option turned off the insertion of Python import statements
+            derived from a %import directive. For example given:
+
+              %module module_b
+              %import "module_a.i"
+
+            then module_b.py will contain:
+
+              import module_a
