N.B. I might have used "forward-compatible" incorrectly above (perhaps
it should have been "backward-compatible"? I get those terms mixed
up...). Everything else there is correct, though. In short, CC
BY-SA-licensed material under a given version of that license can be
re-used under the same or later versions of the license but not under
earlier versions of the license. (I'm assuming all the other
requirements of the license are complied with.)
