Hi everybody, GiNaC 1.5.8 is out and available. The changes are: * Changed default behaviour of conjugate() for user-defined functions to avoid wrong evaluations. A user-defined conjugate_func must now be explicitly registered. * Fixed: Parser now handles abbreviations as advertized in the manual. * Fixed two bugs in the GCD code (one infinite loop, one miscalculation). * Fixed dangerous iterator use. * Fixed a memory leak in excompiler. * Fixed several syntax issues wrt to gcc 4.5 and wrt to compile option -std=cxx0x. * Fixed a wrong URL and a texinfo problem in the manual. * Added degree_vector() utility function. As always, this release can be downloaded from http://www.ginac.de/Download.html Best wishes, Jens
