---------------------------------+--------------------------------
 octave-symbolic has been updated to version 2.2.3. New this version:
 * New commands:
  - cross
  - dot
 * sym('var') is more robust in case var happens to be a special  value in
 SymPy.  Now sym('E') is just a symbol rather than exp(sym(1)).  Also
 sym('E1') and sym('Eq') no longer give errors.
 * Fix bug in assigning to column vectors.
 * Fix for Octave 4.1+ development versions.
