Building clisp 2.44.1 manually fixes the problem. * Bug Statistics We closed a record number of 138 tickets. For details see http://trac.sagemath.org/sage_trac/milestone/sage-3.0.2 or check out the closed ticket section at the end of the announcement. * Upcoming Releases The next release will be 3.0.3, chaired by Michael Abshoff. The release is planned in about a week. It will be mostly a bug fix release to clear up issues from the 3.0.2 release. * Doctesting Coverage For 3.0.1 we had: Overall weighted coverage score: 51.8% Total number of functions: 19553 We increased coverage by 0.4% in 3.0.2 while adding 211 functions: Overall weighted coverage score: 52.2% Total number of functions: 19764 * Closed Tickets: Merged in rc3: #3285: Robert Miller: segfault in binary_code.pyx on 32-bit linux #3287: William Stein: worksheet.py -- doctest failure blocking a release #3288: Robert Miller: linear_code -- memory errors in doctests on Arch Linux #3289: Robert Miller: linear_code -- segfaults on ubuntu linux #3291: Gary Furnish: pbuild doesn't properly compile mwrank.so on some systems Merged in rc1/2: #3279: Michael Abshoff: Sage 3.0.2.rc0: Copy dsage_* scripts from the scrips.spkg #3280: Michael Abshoff: Sage 3.0.2.rc0: fix rebuild Sage documentation issues #3281: Gary Furnish: libecm fails to pbuild Merged in rc0: #1762: Robert Miller, Michael Abshoff: Create optional graphviz package #2121: Robert Miller: move libecm wrapper from interfaces to libs #2519: Franco Saliola, Peter Jipsen: Add support for posets, semi-lattices, etc. to Sage #3018: Bjarke Hammersholt Roune: Integrate Frobby into Sage #3097: Gary Furnish, Michael Abshoff: pbuild: make sure the files from setup.py's scripts section are copied #3104: William Stein: pbori.pyx: Make some doctest long since it uses a lot of RAM #3112: Robert Miller: Generate self-orthogonal binary codes #3148: Francis Clarke: improved orthogonal functions #3218: Michael Abshoff: fix 64 bit OSX build support for mercurial #3219: William Stein: upgrade to gmp-4.2.2 while we wait for MPIR #3242: Robert Miller: Fix little bug in G.relabel() for G a graph #3245: Mike Hansen: provide coefficient and coefficients methods for symbolic expressions #3257: Gary Furnish: Pbuild ignores gcc specific default settings #3263: Craig Citro: typo in lseries_ell.py #3266: William Stein: Sage 3.0.2.alpha1: doctest failure in sage/server/simple/twist.py #3267: Michael Abshoff: Sage 3.0.2.alpha1: doctest failure in sage/server/support.py #3269: Jason Bandlow: Improve documentation for combinat/dyck_word.py #3270: Robert Miller: trivial 100x speedup in coding theory #3272: Craig Citro: Bug in sparse polynomials over finite fields #3273: Robert Bradshaw: extend isqrt to work for Python int's in addition to Sage integers and objects with an isqrt method #3274: Michael Abshoff: OSX: delete libpng*.la since we also nuke libpng*.dylib #3275: Craig Citro: Make SL2Z distinct Merged in alpha1: #406: William Stein: notebook -- make tab completion not stick gap. when using the notebook in gap mode #637: William Stein: notebook improvement -- upload allow txt worksheets. #1733: William Stein: notebook bug -- %foo (or anything else) in a cell by itself (with nothing else in the cell) does not give an error but it *should* #1864: William Stein: simple notebook bug -- typing ? in a comment yields introspection but shouldn't #1892: William Stein: notebook -- uploading a data file should give some help about the DATA variable #2359: William Stein: notebook -- make it so when you send a kill signal to the notebook server it saves state #2636: William Stein: notebook -- changing a cell without evaluate should put the red line back to the left #2860: William Stein: easy-to-fix bug in html.py #2884: William Stein, Tom Boothby: notebook -- bug;
