Hi, GiNaC 1.3.1 is out and available. The changes are: - integral() and eval_integ() can be used from ginsh. - Integrals can be series-expanded. - Fixed a library initialization problem. - GiNaC compiles from tarball even if lex/flex is missing. - Fixed bugs in canonicalize_clifford(), clifford_prime() and clifford_to_lst(). - clifford_moebius_map(), remove_dirac_ONE() and LaTeX output of Clifford objects now care about representation labels. - Fixed bug in gcd. - Better output for slashed expressions. As always, this release can be downloaded from ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/ Enjoy, Jens
