Hello folks, Sage 3.3 was released on February 21st, 2009. It is available at http://www.sagemath.org/download.html * About Sage (http://www.sagemath.org) Sage is developed by volunteers and combines 83 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.

The final status report can be found at http://wiki.sagemath.org/days12/statusreports?action=AttachFile&do=view&target=report.pdf We also updated various Sage components with known security issues, so please update if you run a Sage server, especially if it is exposed to the public net. Aside from the above there a are very large number of improvements as well as updates to the components of Sage. One of the new major usability improvements to the notebook is the addition and integration of the TinyMCE editor which now allows to add inline text cells to the notebook via a very nice WYSIWYG editor. This was made possible by Jason Grout who while working on this ticket did also clean up the way Sage's other Javascript based components were installed and used. For all the details of what else changed in Sage 3.3 please see the release tour in the Sage wiki at http://wiki.sagemath.org/sage-3.3 * Known Issues with 3.3: * RHEL 5 clisp build issue: the latest clisp.spkg does not build so please use the clisp.spkg from Sage 3.0.3. * On Fedora Core 9 and 10 system Sage can fail at startup due to "out of memory" conditions related to libSingular. These failures are due to a bug in the Fedora kernel's new security features that interacts poorly with libSingular's memory allocation system. It also seems to be much more easily triggered on 64 bit platforms. The bug indeed was first detected about 9 months ago, but we hoped that the kernel would be fixed; we have decided to fix the problem on the Singular side, instead, but have not yet completed the fix. * If you upgrade please delete the old matplotlibrc from $DOT_SAGE, $SAGE_ROOT, and $SAGE_ROOT/tmp since they cause deprecation warnings when doctesting or using certain functionality. These are false positives and caused by the outdated matplotlibrc we used to ship. * Bug Statistics We closed a record 385 tickets. For details see http://trac.sagemath.org/sage_trac/milestone/sage-3.3 or check out the closed ticket section at the end of the announcement. * Upcoming Releases * Sage 3.4 will focus on two major features: The ReST transition of the documentation in Sage spearheaded by Mike Hansen and the merging of Jon Hanke's quadratic forms library code into the main Sage library. This code will play a central role at Sage Days 13 that will take place from February 28th until March 2nd 2009 at the University of Georgia, Athens. This implies that this release will be made in the next 4 days. * Sage 3.4.1 will merge code from the coding sprint of SD 13 as well as fixes for the usual bugs that will crop up. This release ought to be out two or three days after the end of SD 13 and is meant to stabilize the 3.4 series due to the large amount of code that went into the 3.3 and 3.4 release cycles. * Sage 3.4.2 should contain additional bug fixes and maybe even more code for quadratic forms to get ready for the Arizona Winterschool 2009 which takes place during the middle of March. There will be many Sage developers and users there, so this ought to be an interesting workshop. * Doctesting Coverage For 3.2.3 we had: Overall weighted coverage score: 64.3% Total number of functions: 21982 We increased coverage by 0.7% in 3.3 while adding 247 functions: Overall weighted coverage score: 65.0% Total number of functions: 22229 * Closed Tickets: Merged in Sage 3.3.final: #1641: William Stein: Make ATLAS restart build on tolerance error [Reviewed by Michael Abshoff] #5329: William Stein: sage-3.3.rc3 -- latex mistake [Reviewed by Michael Abshoff] #5327: Robert Miller: multiple edge plots use symbolic computations [Reviewed William Stein] Merged in Sage 3.3.rc3: #4440: Alexander Hupfer, Tom Boothby: Automatic Indentation [Reviewed by Jason Grout] #4746: Robert Bradshaw: Bug in srange [Reviewed by Carl Witty, William Stein] #4688: Maite Aranes, Alex Ghitza: wrap pari functions idealstar and ideallog [Reviewed by John Cremona] #4779: William Stein: make function for creating random rings and running automated testing on them [Reviewed by Martin Albrecht, Michael Abshoff] #5104: Robert Bradshaw: setup.py dependency checking issues [Reviewed by Michael Abshoff] #5216: Mike Hansen: Update bzip2 to 1.0.5 release [Reviewed by Michael Abshoff] #5251: Robert Bradshaw: preparser bug in parsing the backslash "solve right" notation [Reviewed by Mike Hansen] #5257: Mike Hansen: Clicking on "Log" in the notebook (bringing you to the /history page) gives errors [Reviewed by Michael Abshoff] #5287: Martin Albrecht: improve mq.SR usability and performance [Reviewed by William Stein] #5293: Tom Boothby: tab-completion menu creates two copies of the choice made [Reviewed by Marshall Hampton, Jason Grout] #5301: William Stein: In sage-3.3.rc2, doing sage -t -long "devel/sage/sage/plot/plot.py" causing a matplotlib GUI window to popup [Reviewed by Michael Abshoff] #5302: Robert Miller: Numerical noise in graph.py get_pos() and graph_plot.py [Reviewed by Jaap Spies, Michael Abshoff] #5303: Michael Abshoff: Sage 3.3.rc2: numerical noise in sage/schemes/elliptic_curves/sha_tate.py [Reviewed by William Stein, John Cremona] #5304: Michael Abshoff: Sage 3.3.rc2: Fix documentation build [Reviewed by Mike Hansen] #5309: William Stein: mark some doctests in misc/package.py #optional - internet [Reviewed by Michael Abshoff] #5311: Michael Abshoff: Update to ATLAS 3.8.3 (latest upstream release) [Reviewed by Glenn Tarbox] #5314: Florent Hivert: The empty permutations exists!
