* Notebook updates (Timothy Clemans)
* @parallel and pyprocessing (William Stein, Tom Boothby, Mike Hansen)
For details see the Sage 3.0.4 Release Tour at
http://wiki.sagemath.org/sage-3.0.4
* Known Issues with 3.0.4:
* RHEL 5 clisp build issue: the latest clisp.spkg does not build
so please use the clisp.spkg from Sage 3.0.3.
* Bug Statistics
We closed 131 tickets. For details see
http://trac.sagemath.org/sage_trac/milestone/sage-3.0.4
or check out the closed ticket section at the end of the
announcement.
* Upcoming Releases
The next release will be 3.0.5, chaired by Michael Abshoff. It will
focus on getting optional packages to work well and fix some of the
remaining blockers left over from 3.0.4. This will be the ISSAC
release, so we should really make this a good one.

For 3.0.3 we had:
Overall weighted coverage score: 52.5%
Total number of functions: 19949
We increased coverage by 1.1% in 3.0.4 while adding 284 functions:
