Hi Sage-Devel, See below -- Singular 3-1-0 has been released.
Note that their polynomial factorization over GF(p) is still broken (I try to factor the same polynomial over GF(3) twice and get different answers). I'm reporting this here: http://www.singular.uni-kl.de/request_form.html wst...@sage:~/tmp/Singular/3-1-0$ x86_64-Linux/Singular SINGULAR / A Computer Algebra System for Polynomial Computations / version 3-1-0 0< by: G.-M.
