Google: Rel=prev/next Is Not An Indexing Signal Anymore; Help Docs Removed

Yesterday during the webmaster hangout, I noticed that the documentation on "Indicating paginated content to Google" that talks about rel=next/prev is now gone, 404ing. Also, the blog post about it from 2011 in bold reads at the top "Note: The information in this post is outdated. Rel=prev/next is not an indexing signal anymore."
