Tim Burke a8d377c96d Use temporary redirects for future series

That doesn't seem like a good idea when we *know* that the redirect
location is going to change, and on a reasonably short time scale. Use
302 instead; 303 or 307 would probably work as well, but 302 should have
very broad client support.
