Hello everybody, GiNaC 1.4.4 is out and available. The changes are: * Fixed a bug in the multiple polylogarithms Li/G that caused imaginary parts of the arguments to be ignored. * Fixed archiving of complex numbers. * Made the behaviour of class function more consistent with respect to ncmul::eval(). * Fixed a bug in power::is_polynomial. * Improved heur_gcd() so it can handle rational polynomials. * Improved build scripts. As always, this release can be downloaded from http://www.ginac.de/Download.html Best wishes, Jens
