Hello! We're proud to present GiNaC release 1.1.7 "Legacy of Taylor" in which we: - Fixed a bug in canonicalize_clifford(). - Series expansion now works predictably. All terms with the exponent of the expansion variable smaller than the given order are calculated exactly. If the series is not terminating, the Order function is (at least) of the given order. Predictably, this release can be downloaded from ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/ Never stop coding, Christian -- / Physics is an algorithm \/ http://www.uni-mainz.de/~bauec002/
