#1861's issues have already been dealt with on the wiki, which is more or less official, so that is good now.
The spkg is located here. I see that 0.8 has all the other good changes mentioned at #1861 and elsewhere.
A question about the 0.8 spkg, though perhaps that doesn't belong here:
$ hg st
? emacs/sage-load.el
Ivan, do you think the goal of this ticket should be 0.7 on the optional spkg? If so, then since Nick wrote it, you can review it. For 0.8, though, you'd have to find someone else to review it, and that could take a while. I recommend the former course. In that case we can open another ticket for 0.8, where all these doc issues are 100% taken care of, I already given positive review to that stuff and the spkg qua spkg (well, except for the thing above!).
