You can get Octave 2.9.6 in Ubuntu (edgy) in the package octave2.9.
It's in the edgy universe repository.  I presume 2.9.10 will turn up
there eventually?  The Ubuntu package "octave" is just an alias for the
package "octave2.1".

You can have both octave2.1 and octave2.9 packages installed.  The real
binaries are /usr/bin/octave-2.1.73 and /usr/bin/octave-2.9.6.  The
packages provide symbolic links octave2.1 and octave2.9 for these, and
another link /usr/bin/octave to /etc/alternatives/octave which is itself
a symbolic link to /usr/bin/octave-2.1.73 if you have octave2.1
installed or otherwise to /usr/bin/octave-2.9.6 if you have octave2.9
but not octave2.1 installed.

Not too high.  Acceptable, I think.  Personally though since updating to
octave2.9 I haven't looked back.  Lots of great new features and I don't
recall encountering any backward incompatibilities.
