Hello, Sage-2.8.6 (http://sagemath.org) has been released!
Many people including (but not limited to) Nils Bruin, Yi Qiang, Craig Citro, Joel Mohler, Martin Albrecht, William Stein, Jason Grout, Robert Bradshaw, Michael Abshoff, Soroosh Yazdani, Justin Walker, David Harvey, Robert Miller, and Gonzalo Tornaria contributed new code to this release. As usual, there is a huge amount of code "in the pipeline" that is not in this release yet. Some of the main highlights include: * Robert Bradshaw -- upgrade Cython * Martin Albrecht -- upgrade singular * Jason Grout (refereed by Robert Miller) -- lots of updates to the graph theory package * Mike Hansen -- updates to combinatorics; improved how multi-variate poly rings print. * William Stein -- many bug fixes * Martin Albrecht -- many small improvements to commutative algebra * Joel Mohler -- optimizations * Soroosh Yazdani -- improvements to smith normal form * Gonzalo Tornaria and William Stein -- made pari c library interface automatically * Change Sage library to "GPL version >= 2." * Craig Citro and William Stein -- improvements to scons so that branch switching works. ---------------------------------------------------------------------------------------------- 741 sage -bdist: after doing this in sage-2.8.5, the dsage unit tests don't run for the resulting binary 763 serious bug latexing p-adic L-series 769 Matrix_mod2_dense._echelon_strassen gives false results sometimes 528 write new Integer_mod_dense class that wraps NTL directly 593 MPolynomialIdeal.reduced_basis() doesn't behave as expected 694 SAGE's multivariate gcd sucks over QQ and/or ZZ 701 port srange to Cython for speed 719 make pari.allocatemen() more clever 728 sage_inspect broken 735 issues with server timing out worksheets 745 update the version of FLINT that is in Sage 746 graphs: graph name is not reset using clear() 747 flint build problem on itanium 755 graphs: adjacency_matrix() does not call multiple_edges correctly. 759 graphs: density returns incorrect result for directed graphs. 764 repr(PolynomialRing(ZZ, 1, 'x')) is ambiguous 770 Bad behaviour when Ctrl-C hit while running an expect interface 776 kernel of linear homomorphism fails 784 quotient spaces of vector spaces 789 Can't create a submodule over a QQ[x]-module 798 MPolynomial_libsingular.subs 801 graphs: Latexify module-level documentation 806 matrix_integer_dense.elementary_divisors return a mutable object 809 class_graph fixes 810 gens_reduced for general ideals 816 Commutative Algebra assorted functionality 817 O(3^(-2)) is broken 818 Convert of prod to Cython 822 Some matrix multiplications inefficiencies 730 graphs: fickle equality testing 736 combinatorics updates 761 graphs: Lots of various doc changes and additional doc tests. 774 graphs: change "node" to "vertex" 782 sage -testall should support ctrl-C 786 standard smith normal form 794 MPolynomial_libsingular.jacob() 796 Yet another fix for c_lib/scons stuff 802 graphs: Streamline and document _cmp_ more 760 graphs: a small change to subgraphs allow it to default to the original graph. 795 tiny documentation update for MPolynomialIdeal.groebner_basis 802 graphs: Streamline and document _cmp_ more 760 graphs: a small change to subgraphs allow it to default to the original graph. 795 tiny documentation update for MPolynomialIdeal.groebner_basis -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
