Yes, there are differences. I, however, can't remember them all. I would
guess that most of the differences are related to the symbol table. So,
if you are only using the basic class (Matric, Cell, ...), then you
won't have to change anything. The easiest way to figure out, is (IMHO)
to try to compile your code with Octave 3.2. Most of the code in
Octave-Forge didn't have to be changed.

The manual is kept with the Octave source code in the 'doc/interpreter'
directory.

There will be changes to the oct interface as well in 3.4. Of the top of
my head, I remember that 'ArrayN' will be deprecated in favour of
'Array', but other changes are likely as well.

In general, the interface is not stable. A stable interface has been
discussed, but we have yet to decide on an API.
