WordPress incoming links have gone

After “WordPress” released new Wordpess version 2.8 there was many strange problems with it. Lots of bloggers noticed that there was no incoming links available anymore after logging in. I haven’t found an answer on the forums but I got the same problem. Several days later when WP 2.8 was released I found one incoming link on the list however the link was gone next day. People think that it may be a problem with WP version 2.8 but my personal opinion is that Google has changed the Page rank policy. I just noticed the difference after new WordPress version was released because all my incoming links have gone. I have checked all the Websites (blogs) and backlinks that was on the list but everything was fine and no links were removed from other blogs so there is a very strange thing with that because all these links can increase page rank.
