But there is no official statement as such! Here are some of the key points that have emerged out of the thread:

1. Link counts have seen some amount of drop
2. Canonical issues are discussed in a major way
3. One person is reporting I am seeing two different titles and descriptions for singular vs. plural of my main keyword. It's the same URL, so kind of odd.

But the issue that now arises is why Yahoo! is not giving any kind of official statement on it? But the Yahoo Search Japan blog has already announced it. Here is the translation

Yahoo! In search, Yahoo! Inc. UEBUSACHIENJIN has developed the "Yahoo! Search Technology (YST)" has started a full update of the index.
