Hello everybody, GiNaC 1.4.2 is out and available. The changes are: * Fixed VPATH building of documentation. * Fixed bug in numerical evaluation of multiple polylogarithms for arguments equal to certain roots of unity (thanks to Jianqiang Zhao). * Fixed check for memory leakage in parser. * Made internal function coerce() standard compliant. * Improved lsolve() of systems containing non-numeric coefficients. * Improved automatic test programs. Now they work on MinGW and Cygwin as well. As always, this release can be downloaded from http://www.ginac.de/Download.html Best wishes, Jens
