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. + +1.5.7 (29 March 2010) +* Fixed a bug in the GCD code (infinite loop in pgcd()). +* Fixed a bug in atan2() (division by zero error for atan2(x,0) if x is a + negative and composite term). +* Products now correctly set info_flags::negative and info_flags::negint. + 1.5.6 (28 January 2010) * Fixed compile problem with gcc 3.4. * Improved excompiler: The ginac-excompiler script will only be installed if
