Hi folks,
Sage 4.3.4 was released on March 19, 2010. It is available at
http://www.sagemath.org/download.html
* About Sage (http://www.sagemath.org)
Sage is developed by volunteers and combines over 90 open source packages.
It is available for download from www.sagemath.org and its mirrors in
source or binary form. If you have any questions and/or problems,
please report them to the Google groups sage-devel or sage-support.
You can also drop by in #sage-devel on freenode.

Binary for t2.math will be announced in a day or two. I have started a
build of Sage 4.3.4 on t2.math and it would take over 24 hours for the
build to complete.

* Major features, new spkg's, and bug fixes
* Merged 16 tickets enhancing the combinatorics module. A big thank
you to the Sage-Combinat team for their hard work before and during
Sage Days 20 to get those tickets merged.
* Sage now builds on SPARC Solaris 10, in particular on the machine
t2.math.washington.edu. A big thank you to David Kirkby for his
consistent hard work to get Sage to build on that machine. Please also
thank Jaap Spies and John Palmieri for their work on getting Sage to
build on t2.math.
* New spkg: iconv-1.13.1
* Removed spkg: pyprocessing-0.52.p0
* Upgraded spkg's: ecl-10.2.1, mpfr-2.4.2, mpmath-0.14,
sagenb-0.7.5.3, sqlalchemy-0.5.8, sqlite-3.6.22, twisted-9.0.p2
* Updated spkg's: atlas-3.8.3.p12, cddlib-094f.p5,
eclib-20080310.p10, flint-1.5.0.p4, python-2.6.4.p7, r-2.10.1.p0,
sagetex-2.2.3.p0, scipy-0.7.p4, zn_poly-0.9.p3
* Bug statistics
We closed 120 tickets. For details see
http://trac.sagemath.org/sage_trac/milestone/sage-4.3.4
or check out the closed ticket section at the end of the announcement.
* Upcoming release
The upcoming major release is Sage 5.0, scheduled to be released in
early June 2010. The goals for Sage 5.0 include:
* Resolve the high-impact tickets at
http://trac.sagemath.org/sage_trac/wiki/stab1
* Raise the doctest coverage score to 90% by removing the notebook
from the score and writing about 1500 docstrings
* Official 32-bit Solaris 10 support on SPARC (automatic build, all tests pass)
* Official Cygwin support (automatic build, all tests pass)
* Doctesting coverage
To my dismay, this release of Sage actually has a decrease in doctest
coverage. For Sage 4.3.3, we had an overall weighted doctest coverage
score of 81.6%, with 24,808 functions. In Sage 4.3.4, we decreased the
doctest coverage by 0.1% and added 314 new functions. Thus for Sage 4.3.4
we now have
* Overall weighted coverage score: 81.5%
* Total number of functions: 25,122
* Known issues
* Kiran Kedlaya reported that Sage can fail to compile on 64-bit
Fedora 10. This build problem occurs after we added the new iconv
spkg.
