For all the details of what else changed in Sage 4.3.1, please see the release tour on the Sage wiki at http://wiki.sagemath.org/ReleaseTours/sage-4.3.1 * Bug Statistics We closed 193 tickets. For details see http://trac.sagemath.org/sage_trac/milestone/sage-4.3.1 or check out the closed ticket section at the end of the announcement. * Upcoming Release The upcoming release is Sage 4.3.2, planned to be release in time for Sage Days 20 in Marseille, France, from February 22 to February 26, 2010. For more information on Sage Days 20, see its official website http://www.lirmm.fr/arith/wiki/MathInfo2010/SageDays or the Sage wiki page http://wiki.sagemath.org/daysmarseille * Doctesting Coverage For Sage 4.3, we had an overall weighted doctest coverage score of 80.8%, with 23,763 functions. In Sage 4.3.1, we increased the doctest coverage by 0.5% and added 634 new functions. Thus for Sage 4.3.1 we now have * Overall weighted coverage score: 81.3% * Total number of functions: 24397 * Known issues Sage 4.3.1 was planned to be a release in which Sage would build successfully on SPARC Solaris 10, especially on the machine t2.math.washington.edu During development, a ticket was merged that prevented a successful build on that platform. We are tracking this issue at ticket #7932. Building the reference manual can result in some errors due to a bad docstring formatting. We are tracking this issue at ticket #8021. Fortran is now a pre-requisite for building Sage on Linux. During compilation on Linux, you might receive the following error message: Error installing Fortran: You must install gfortran or set SAGE_FORTRAN (and possibly SAGE_FORTRAN_LIB). If so, then you need to first install Fortran using your Linux distribution's package manager. After that, you can resume building Sage. * Closed Tickets #1439: make install_package('...') through the notebook far less verbose #1663: Tim Dumol: scipy build fails in tr_TR locale [Reviewed by Burcin Erocal] #1964: attaching multiple files should work but is broken (or never implemented?) #2145: doc -- add shift-enter prominently to both the reference manual and tutorial (easy doc fix) #2174: upgrade -- make upgrade() so that when run in the notebook it is not very verbose #2899: Make RDF round and friends return Integers #3089: removing an attached file doesn't work #3114: blacklist gcc version 4.0.0 on OSX #3329: attempting to convert relative number field elements to Singular should fail quickly #3469: Something funny with free modules #3777: notebook -- issue parsing out
