[GiNaC-devel] GiNaC release 1.5.7

[Jens Vollinga]

Hi everybody,

GiNaC 1.5.7 is out and available. The changes are:

* Fixed a bug in the GCD code (infinite loop in pgcd()).
* Fixed a bug in atan2() (division by zero error for atan2(x,0) if x is
   a negative and composite term).
* Products now correctly set info_flags::negative and
   info_flags::negint.

As always, this release can be downloaded from

Best wishes,
Jens
