Checking the sage-release Google group is not a bad place to start. I thought there was also a link to the 'bleeding-edge' status on the main Sage site front page, but apparently I was mistaken. But don't feel bad asking; I was replying to one of the people replying to you, who did not read the previous posts carefully. Always feel free to report bugs in the latest 'official' release here - we don't require users to have development releases, which by definition may not be stable. - kcrisman -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
