These take us closer to a complete Cygwin build, thanks to Mike Hansen. * New spkg: cephes-2.8 * Upgraded spkg: pynac-0.2.0.p3 * Updated spkg's: boehm_gc-7.1.p5, gd-2.0.35.p5, ntl-5.4.2.p12, pari-2.3.5.p1, polybori-0.6.4.p1, python-2.6.4.p8, scipy-0.7.p5, scipy_sandbox-20071020.p5 * Bug statistics We closed 40 tickets. For details see http://trac.sagemath.org/sage_trac/milestone/sage-4.4.3 or check out the closed ticket section at the end of the announcement. * Doctesting coverage For Sage 4.4.2, we had an overall weighted doctest coverage score of 82.1%, with 25,513 functions. In Sage 4.4.3, added 3 new functions.
