Sorry.
I updated http://alpha.sagenb.org to sage-4.0.rc0, and strongly encourage people to try it. Especially try symbolic calculus computations since we switched from Maxima to Ginac for the core of symbolics in sage-4.0. I've built this on a number of machine and there are a number of doctest failures, segfaults, and other issues that pop up when not building on sage.math. To get sage-4.0 formally released requires (at least) two things: (1) sort out all these doctest failures (2) get the new pynac-based symbolics code refereed: http://trac.sagemath.org/sage_trac/ticket/6111 William > > Cheers, > > Michael > > Merged in Sage 4.0.rc0: > > #6104: Michael Abshoff: Fix Solaris specific build issue for > libfplll.spkg [Needs review] > > #3932: Ryan Dingman: generate size n trees in linear time [Reviewed by > Robert Miller] > #4875: Marshall Hampton: Polyhedron.show(fill=True) fails [Reviewed by > David Perkison] > #5076: David Roe: bug with (coercion in?) p-adic extension fields > [Reviewed by Robert Bradshaw] > #5120: Nicolas Thiery: An alternative implementation of the Unique > Representation design pattern [Reviewed by David Roe] > #5236: David Roe: x^(-pm) in ramified extensions of Qp [Reviewed by > Kiran Kedlaya] > #5554: Nick Alexander: implement cholesky_decomposition for matrices > other than RDF [Reviewed by Rob Beezer, Michael Abshoff] > #5581: Marshall Hampton: Face lattices and f-vectors for polytopes;
