GNU Octave, a high-level programming language for numerical computations and an open-source alternative to MATLAB, is out this weekend with a huge release. Meet GNU Octave 4.0.

The GNU Octave 4.0 release now uses a GUI by default when running interactively, defaults to using OpenGL graphics with Qt while having fallback support for Gnuplot and Fltk, adds new audio functions/classes, makes other language additions, and has a whole lot of other changes.

Those wanting to learn more about GNU Octave 4.0 can visit its GNU.org project site and/or read the 4.0 NEWS file.
