Hi,
I've released sage-2.8. Get it now at http://sagemath.org/ or
do "sage -upgrade". (Binaries will appear in the near future.)
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.
NOTE: GCC-4.2 support isn't quite there yet, though we're very close
(M Abshoff did build SAGE under GCC-4.2, but there are some issues).
We'll
try for GCC-4.2 support in SAGE-2.8.1.

------------------------
2.8:
* 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.
