I guess it started with 2.1.51:

great fanfare when it finally came into existence.  I'm not sure of the 
limitations and differences with MATLAB.

You'll want to install the most recent Octave *and* Octave-forge:

http://www.octave.org/
http://octave.sourceforge.net/
http://sourceforge.net/projects/octave/
http://wiki.octave.org/

Always get the most recent development versions.
