A new GiNaC release is out and available. These are the changes:

* Fixed pow(+(...),2).expand() where the sum contained roots of rationals.
* Various improvements for info(info_flags::nonnegative).
* Make power::expand() (x*p)^c -> x^c * p^c, if p>0.
* Fixed normal() where nested functions occur multiple times.
* Add optional explicit derivatives to functions and use it in abs(),
imag_part(), real_part().
* Evaluate abs(z)^(2n) -> z^n * conjugate(z)^n.

Happy hacking
Richard B. Kreckel
