I built the source tarballs with a slightly-out-of-date tree. We slipped the release by a day to get two fixes in, but the tree I built from didn't have those two fixes.
I yanked the tarballs off the release page as soon as I suspected something. I'm rebuilding the tarballs and the docs now. If you grabbed the tarball as soon as it appeared, it's slightly out of date, please re-grab.
