I've already tagged 1.8 and am waiting for Ralf to do the binaries. If we get this figured out, we could maybe do a 1.8.1, but I'd rather figure out something for 1.9. This doesn't fall into the category of a bug fix and it isn't clear to me that we yet have a consensus on what should be done, or for that matter, what has already been done. For instance, IIRC, PyArrayNeighborhoodIterObject goes back several releases. All that makes me loathe to stop the 1.8 process at this point.
