+ [Octave] add support for version 4.2.0
+ - C++11 compiler is required to compile examples/test suite
+ - Octave has dropped support for << and >> operators, so SWIG now
+ ignores them
+ - The Octave error() function now raises C++ exceptions to propagate
+ Octave errors, so %exception directives may need to be modified.
+ For convenience the SWIG_RETHROW_OCTAVE_EXCEPTIONS macro can be used
+ to rethrow any Octave exceptions for Octave itself to handle, e.g.:
+
+ try {
+ $action // may call error()
+ }
+ SWIG_RETHROW_OCTAVE_EXCEPTIONS // error() exceptions are rethrown
+ catch(...) {
+ ... // all other exceptions
+ }

-As of SWIG 3.0.7, the Octave module is regularly tested with Octave versions 3.2.4, 3.8.1, and 4.0.0.
-Use of older Octave versions is not recommended, as these versions are no longer tested with SWIG.
+SWIG is regularly tested against the following versions of Octave: 3.8, 4.0, 4.2.
+</p>
+
+<p>
+Every effort is made to maintain backward compatibility with older versions of Octave.
+This cannot be guaranteed however, as in recent times new Octave releases have required nontrivial updates to SWIG, which may break backward compatibility for older Octave versions against which SWIG is not regularly tested.

The SWIG runtime exports the function <tt>swig_octave_prereq()</tt> for checking the version of Octave.
