Oh, I see. The plan, as discussed at the release meeting at Gophercon
but probably never sent to the list, is to do another real release
candidate later this week. The 1.7rc2 release candidate was just
pushed out for the security fix. For the next release candidate all
the relevant changes (which is probably all the changes except for one
that was committed accidentally and then reverted) will be migrated
from the master branch to the 1.7 branch.
