Several new features have been added to the 3.6.N series. The full details are in [https://www.gnu.org/software/octave/NEWS-3.6.html the NEWS file], but in brief 3.6.N series brings:
Each new Octave release introduces many new features.  The following are
a distilled list of the major changes.  A complete list of user visible
