symbolic 2.2.0 released

[Carnë Draug]

Hi everyone

a new release of the symbolic package [1] is out, version 2.2.0, by
Colin B. Macdonald.
A summary of important user-visible changes is also available online [2].

This package adds symbolic calculation features to GNU Octave.
These include common Computer Algebra System tools such as algebraic
operations, calculus, equation solving, Fourier and Laplace transforms,
variable precision arithmetic and other features.  Internally, the
package uses [SymPy](www.sympy.org), but no knowledge of Python is
required.  Compatibility with other symbolic toolboxes is intended.

Enjoy Octave responsibly,
Carnë
