Hi folks, Now that all binaries are in place and the standard documentation is up, I thought it's a good time to post the release note here and give a link to the release tour. Note that sage-announce is the appropriate place to do this, but only the sage-announce group admin can do that. So here goes. A nicely formatted release tour can be found at
