Hello folks,
Sage 2.10.4 has been released on March 17th, 2008. It is available at
http://sagemath.org/download.html
* About Sage (http://www.sagemath.org)
Sage is developed by volunteers and combines 71 open source packages.
It is available for download from 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, sage-support,
You can also drop by in #sage-devel or #sage-support infreenode.
We have closed the Google Groups sage-newbie and sage-forum so
that we can deal with support questions in sage-support only. We
decided to close those two groups since we had various inquiries
left unanswered due to people posting to the wrong group.

* Major Features, New Spkgs and Bugfixes
This
* Memory leaks exposed by modular symbols: Michael Abshoff,
Martin Albrecht, Burcin Erocal, Willem Jan Palenstijn,
Clement Pernet, William Stein: memory leaks exposed by
modular symbols functionality. This ticket is a composite
of numerous other memleak fixes merged over a *7 month*
period. Modular forms are an excellent way to expose
memory leaks in pretty much every algebraic component
of Sage and all known issues there are now finally fixed.
* SQLAlchemy and DSage: We merged SetupTools and SQLAlchemy
into Sage as standard packages. SQLAlchemy is now used as
in DSage replacing hand written code with much more
efficient classes from SQLAlchemy. SetupTools is required
to install SQLAlchemy, but is also useful for a number of
experimental spkgs like Mayavi2, TVTK and other packages
from the Enthought Tool Suite. Yi Qiang improved DSage
making it more robust and finally adding the documentation
to the standard Sage manual.
* Graph theory: chromatic polynomial: An algorithm originally
written in C by Gordon Royle has been adapted by Robert
Miller to replace the old slow method. This algorithm
uses a cut and merge algorithm to recursively compute
the chromatic polynomial, and is written in Cython.
* Documentation: Many doctest patches written during Doc
Day 2 were merged. In addition many people kept up the
good work after Doc Day 2 was over and have been
submitting patches to increase coverage. We did exceed
the target for the release by 0.6% reaching 47.6%.
* Symmetric function updates: Mike Hansen, reviewed by
Franco Saliola: Sage 2.10.4 adds support for Macdonald
polynomials, LLT polynomials, and Jack polynomials as
well as a whole class of user-defined symmetric functions
which can characterized by orthogonality and triangularity
conditions. Support for working with ribbon tableaux was
also added as part of these updates. In addtition, many
doctests were added and subtle bugs fixed.
* Notebook Updates Tom Boothby and William Stein and
Timothy Clemans: Fixed a bunch of new and old issue that
improve the usability of the notebook. Among those are
a working trash, fixes to the polling infrastructure,
saving the content of unevaluated cells, URL issues to
work around problems introduced by restrictive firewalls
and small improvements to the interact command.
* Parallel Doctesting: Gary Furnish reviewed by Michael
Abshoff: "sage -tp" has been introduced as an experimental
multithreaded doctester. The first parameter is the number
of threads, and the second parameter is the folder to
doctest. Thus "sage -tp 4 devel/sage/sage" tests everything
with four threads running. Additional options like "-long"
or valgrind options like "-memcheck" do work. The code base
is still young and needs more testing. The eventual goal
will be to replace the current doctesting infrastructure
with this code base.
* SBox Class: Martin Albrecht introduced a new S-box class
to Sage to support (algebraic) exploration of this
fundamental cryptographic primitive.
* Known Issues with 2.10.4:
* None
* Bug Statistics
We closed 89 tickets. For details see
http://trac.sagemath.org/sage_trac/milestone/sage-2.10.4
or check out the closed ticket section at the end of the
announcement.
* Upcoming Releases
The next release will be 2.11, chaired by Michael Abshoff.
The release is planned in about two weeks. Potential features
(which are also the goals for 3.0) include:
* Upgrade many core components of Sage: Python 2.5.2,
ATLAS 3.8.1, clisp 2.44.1
* 50% doctest coverage
* OSX 10.5 support in 64 bit mode [this will depend on fixing
a vexing segfault in libSingular and getting disutils to
play nice with numpy]
* Pexpect interace to R
* Doctesting Coverage
For 2.10.3 we had:
Overall weighted coverage score: 44.5%
Total number of functions: 18640
We increased coverage by 3.1% in 2.10.4 while removing 24 functions:
Overall weighted coverage score: 47.6%
Total number of functions: 18616
