I don't know what to tell ya. But in IMO, if you click on the title or the last unread link then you should just read the remaining thread. The page delimitation is just an arbitrary delineation. If you don't want to read it then don't click on the thread. What if it was just one long single page, then what part of the thread is considered unread?
In any case here's a link to the initial release notes. And the subsequent bug fix release.
If you want to post this directly to their bug tracker go here. Not sure if you can do this if you're not a customer but give it a shot.
