Hello folks, this is Sage 3.0.alpha2. Up to now we closed 111 tickets. But things are still of alpha quality:
Issue: Invalid read in libgroebner.so (#2822) - this happens with each sage session and results on occasional segfautls at exit. They look like *** glibc detected *** corrupted double-linked list: 0x0000000000958a60 *** They are caused by PolyBoRi, but I am unsure at the moment if it is a general problem or in our PolyBoRi Wrapper. Issue: sage-3.0-alpha1 on ppc -- new randstate code doesn't work right at all (#2814) - you will see loads of doctest failure on PPC OSX since the randgen framework by cwitty has some endianess issues Issue: Linbox build failure on OSX 10.4 intel (#2833) - build will fail in OSX 10.4. So far no solution What is new? Update of Singular, DSage fixes, a LinBox segfault has been fixed and the usual set of other improvements. What is next? gcc 4.3 fixes, the usual set of merges. Alpha3 should be out in the next 48 hours. Sources and binaries are in the usual place: http://sage.math.washington.edu/home/mabshoff/release-cycles-3.0/sage-3.0.alpha2.tar http://sage.math.washington.edu/home/mabshoff/release-cycles-3.0/sage-3.0.alpha2-sage.math-only-x86_64-Linux.tar.gz According to http://trac.sagemath.org/sage_trac/report/13 there are 45 tickets with patches - so please do reviews.
