Yahoo! Search Index Update October 2008

The Yahoo! search blog announced index update on 14th Oct, 2008 as a "Weather Report" with the Yahoo! Site Explorer New Look information they just have done earlier in Aug 2008.

From the Yahoo! Search blog :

We'll be rolling out some changes to our crawling, indexing and ranking algorithms over the next few days and expect the update will be completed soon. As you know, throughout this process you may see some ranking changes and page shuffling in the index.

I am seeing some changes but not much for my sites' SERPs in Yahoo! Search.
