Hi everybody, GiNaC 1.5.4 is out and available. The changes are: * Default parser now can again read in user defined classes. * Add mul::info() and add::info() support for numeric info_flags (GiNaC now can detect that the sum or product of a number of positive expressions is again a positive expression). * Fixed cast that caused compile error on 64bit machines. * Fixed incorrect uses of STL iterators. * Removed subdirectory debian. * Output LaTeX-symbols using \mathrm, instead of \mbox. As always, this release can be downloaded from http://www.ginac.de/Download.html Best wishes, Jens
