Hi folks,

This is the first release candidate for Sage 4.1.2, which mostly fixed
bugs. With the Sage 4.1.2.rc0 release, I'm stepping down as release
manager for the 4.1.2 release cycle and hand over the release chair to
William Stein.

Binary for sage.math is available at

http://sage.math.washington.edu/home/mvngu/release/upgrade/sage-4.1.2.rc0-sage.math.washington.edu-x86_64-Linux.tar.gz

The source tarball is

http://sage.math.washington.edu/home/mvngu/release/upgrade/sage-4.1.2.rc0.tar

You can upgrade with the path

http://sage.math.washington.edu/home/mvngu/release/upgrade/sage-4.1.2.rc0/

Please test and report all issues.


* Known issues for OS X 10.6

This is our first port to Mac OS X 10.6 so there would be many more
bugs to iron out. The OS X 10.6 port is tracked at meta-ticket #6849
[1]. There are still some more packages to update/upgrade before the
OS X 10.6 is complete. I have listed various tickets on the milestone
page [3] that I think need to be resolved before releasing the stable
version of Sage 4.1.2. Please edit that page if there are any tickets
missing.


* Known issues for 64-bit Fedora 11 and 64-bit openSUSE 11.1

If you're going to upgrade to Sage 4.1.2.rc0 or build that version
from source, then you should use the cliquer spkg at ticket #6681 [2].
The version of cliquer that is shipped with Sage 4.1.2.rc0 is known to
fail to build on some 64-bit platforms.
