Seems like Tim Mayer was just a bit late to hit that upload entry button at the Y! Search Blog. He just recently posted Third Weather Report: Yahoo! Launched New Search Index Last Night. This is an update for this mornings entry named Unannounced Yahoo! Search Update.
I guess the SEO forums beat him to it.
Tim told me to expect more changes soon, this is not the end of it he said. He also writes in the blog, "The changes will be a little more intense than the second weather report and changes will continue over the next week or two."
