Hello! We haven't had an update in a while, and the radical new features of GiNaC 1.2 are taking a bit longer, so I've packed up the latest fixes of the 1.1 line in a nice release: GiNaC 1.1.2 - Fixed a bug in the unarchiving of sums and products: terms were not reordered in a canonical way. - Fixed a bug in normal()/numer_denom(): denominator was not made unit normal if it was a simple number. - Improved the speed of subs() in some cases. As usual, it's on ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC For oldskool fans, there's also a GiNaC 1.0.15 that contains the same two bug fixes.
