Sun Aug 12 18:22:22 2007 ------------------------ This is a fairly nontrivial upgrade, mainly because it includes a major new version of Singular, and updates to Linbox. There's also new graph theory-related code that came out of the summer REU at Washington and optimizations to mwrank. If you wrote something, sent me a patch, and it isn't in here, definitely send me an email with a new version of the patch. Thanks to the many many people who contributed to this release, including M Abshoff, M Albrecht, C Citro, C Pernet, D Kohel, G Nebe, D Joyner, E Kirkman, R Miller, S Howe, J Mohler, B moretti, J. Rivas, and anybody else who I didn't mention explicitly. High level change log: * m albrecht: upgrade to singular-3-0-3 (this was nontrivial) * m albrecht, c pernet: new version of givaro that fixes some bugs. (gcc-4.2 support) * m abshoff, c pernet, w stein: new version of linbox that fixes some bugs. (gcc-4.2 support) * d kohel, g nebe, et al.: Genus computation for quadratic forms (not really made public yet but it is there in quadratic_forms/genus). * e kirkman, r miller: graph database improvements (which are generally useful). * s howe, r miller: bruhat intervals * j mohler: programming guide improvement * b moretti: cayley graphs * juan m bello rivas: fix so clisp can be built in the background. * w stein: upgraded sympy to version 0.5.1, whose main features included much optimization * w stein: implement computing half_integer_weight_modform_basis function for computing a basis for half-integral modular forms of given weight, level, and character.
